Needs assessment for manufacturing ceramic gas turbine components  

SciTech Connect

An assessment of needs for the manufacturing of ceramic gas turbine components was undertaken to provide a technical basis for planning R&D activities to support DOE`s gas turbine programs. The manufacturing processes for ceramic turbine engine components were examined from design through final inspection and testing. The following technology needs were identified: Concurrent engineering early in the design phase to develop ceramic components that are more readily manufacturable. Additional effort in determining the boundaries of acceptable design dimensions and tolerances through experimental and/or analytical means. Provision, by the designer, of a CAD based model of the component early in the design cycle. Standardization in the way turbine components are dimensioned and toleranced, and in the way component datum features are defined. Rapid means of fabricating hard tooling, including intelligent systems for design of tooling and rapid prototyping of tooling. Determination of process capabilities by manufacturing significant numbers of parts. Development of more robust ceramic manufacturing processes which are tolerant of process variations. Development of intelligent processing as a means of controlling yield and quality of components. Development of computer models of key manufacturing steps, such as green forming to reduce the number of iterations required to manufacture intolerance components. Development of creep feed or other low-damage precision grinding for finish machining of components. Improved means of fixturing components for finish machining. Fewer and lower-cost final inspection requirements. Standard procedures, including consistent terminology and analytical software for dimensional inspection of components. Uniform data requirements from the US turbine engine companies. An agreed-upon system of naming ceramic materials and updating the name when changes have been made.

An application reference model for layered manufacturing  

SciTech Connect

The Intelligent Manufacturing Systems (IMS) Test Case 6 project (Rapid Product Development) was set up to demonstrate rapid product development and 3D measurement techniques where the agencies performing the work were distributed over different countries. Test Case 6 provided a unique opportunity to examine the process by which an application protocol (AP) of the Standard for Exchange of Product Data is prepared. The test case had a well defined scope, the production of simple parts by means of layered manufacturing techniques. The information concerned with this manufacture was similarly well defined, due to the requirement that the information be transmitted among the organizations participating in the test case. STEP is an international standard specifying the data content and format for storage and exchange of product data throughout the product`s life cycle. STEP has been under development since 1984 and is just now emerging as an International Standard. STEP is specified as a series of information models using the EXPRESS computer language. For purposes of data exchange, a mapping to a physical file format is specified. Informally, product data can be defined as all the data about a product which one might wish to save. This definition implies some variation in the amount of data to be saved in any one instance. In the case of Test Case 6, one would certainly wish to save the IGES files describing the part. One may or may not wish to save the manufacturing parameters. While there are many parts of STEP with different purposes, the important series of parts for the purposes of standardizing product data are those dealing with application protocols. An application protocol specifies the details of product data within the context of a single application (in this case, layered manufacturing). Other APs deal with such subjects as configuration-managed solid parts and associated drafting.

Wind turbine composite blade manufacturing : the need for understanding defect origins, prevalence, implications and reliability.  

DOE Green Energy (OSTI)

Renewable energy is an important element in the US strategy for mitigating our dependence on non-domestic oil. Wind energy has emerged as a viable and commercially successful renewable energy source. This is the impetus for the 20% wind energy by 2030 initiative in the US. Furthermore, wind energy is important on to enable a global economy. This is the impetus for such rapid, recent growth. Wind turbine blades are a major structural element of a wind turbine blade. Wind turbine blades have near aerospace quality demands at commodity prices; often two orders of magnitude less cost than a comparable aerospace structure. Blade failures are currently as the second most critical concern for wind turbine reliability. Early blade failures typically occur at manufacturing defects. There is a need to understand how to quantify, disposition, and mitigate manufacturing defects to protect the current wind turbine fleet, and for the future. This report is an overview of the needs, approaches, and strategies for addressing the effect of defects in wind turbine blades. The overall goal is to provide the wind turbine industry with a hierarchical procedure for addressing blade manufacturing defects relative to wind turbine reliability.

Evaluation of Hand Lay-Up and Resin Transfer Molding in Composite Wind Turbine Blade Manufacturing  

DOE Green Energy (OSTI)

The majority of the wind turbine blade industry currently uses low cost hand lay-up manufacturing techniques to process composite blades. While there are benefits to the hand lay-up process, drawbacks inherent to this process along with advantages of other techniques suggest that better manufacturing alternatives may be available. Resin Transfer Molding (RTM) was identified as a processing alternative and shows promise in addressing the shortcomings of hand lay-up. This report details a comparison of the RTM process to hand lay-up of composite wind turbine blade structures. Several lay-up schedules and critical turbine blade structures were chosen for comparison of their properties resulting from RTM and hand lay-up processing. The geometries investigated were flat plate, thin and thick flanged T-stiffener, I-beam, and root connection joint. It was found that the manufacturing process played an important role in laminate thickness, fiber volume, and weight for the geometries investigated. RTM was found to reduce thickness and weight and increase fiber volumes for all substructures. RTM resulted in tighter material transition radii and eliminated the need for most secondary bonding operations. These results would significantly reduce the weight of wind turbine blades. Hand lay-up was consistently slower in fabrication times for the structures investigated. A comparison of mechanical properties showed no significant differences after employing fiber volume normalization techniques to account for geometry differences resulting from varying fiber volumes. The current root specimen design does not show significant mechanical property differences according to process and exceeds all static and fatigue requirements.

Task 4.1 Intelligent Manufacturing of Hybrid Carbon-Glass Fiber-Reinforced Composite Wind Turbine Blades  

DOE Green Energy (OSTI)

EXECUTIVE SUMARY In this subtask, the manufacturability of hybrid carbon-glass fiber-reinforced composite wind turbine blades using Vacuum-Assisted Resin Transfer Molding (VARTM) was investigated. The objective of this investigation was to study the VARTM process and its parameters to manufacture cost-effective wind turbine blades with no defects (mainly eliminate dry spots and reduce manufacturing time). A 2.5-dimensional model and a 3-dimensional model were developed to simulate mold filling and part curing under different conditions. These conditions included isothermal and non-isothermal filling, curing of the part during and after filling, and placement of injection gates at different locations. Results from this investigation reveal that the process can be simulated and also that manufacturing parameters can be optimized to eliminate dry spot formation and reduce the manufacturing time. Using computer-based models is a cost-effective way to simulate manufacturing of wind turbine blades. The approach taken herein allows the design of the wind blade manufacturing processes without physically running trial-and-error experiments that are expensive and time-consuming; especially for larger blades needed for more demanding environmental conditions. This will benefit the wind energy industry by reducing initial design and manufacturing costs which can later be passed down to consumers and consequently make the wind energy industry more competitive.

Reference wind speed distributions and height profiles for wind turbine design and performance evaluation applications. [USA  

DOE Green Energy (OSTI)

The purpose of this report is to provide a set of reference or standard values of wind profiles, wind speed distributions and their effects on wind turbine performance for engineering design applications. Based on measured Weibull distribution parameters, representative average, low, and high variance data are given for height profiles of mean, 25 percentile, and 75 percentile wind speeds; and for wind speed probability density (velocity frequency) functions and cumulative probability (velocity duration) functions at selected heights. Results of a sensitivity analysis of the dependence of wind turbine performance parameters on cut-in speed, and rated speed for various mean wind and wind variance regimes are also presented. Wind turbine performance is expressed in terms of capacity factor (ratio of mean power output to rated power) and recovery factor (ratio of mean energy output to energy theoretically available in the wind). The representative high, mean, and low variance cases were determined from calculated Weibull distributions at 140 sites across the Continental U.S., and all of the representative functions are evaluated at mean wind speeds of 4, 5, 6, 7, and 8 m/s at standard 10 m level.

The objective of the the Direct Coal-Fueled 80 MW Combustion Turbine Program is to establish the technology required for private sector use of an advanced coal-fueled combustion turbine power system. Under this program the technology for a direct coal-fueled 80 MW combustion turbine is to be developed. This unit would be an element in a 207 MW direct coal-fueled combustion turbine combined cycle which includes two combustion turbines, two heat recovery steam generators and a steam turbine. Key to meeting the program objectives is the development of a successful high pressure slagging combustor that burns coal, while removing sulfur, particulates, and corrosive alkali matter from the combustion products. Westinghouse and Textron (formerly AVCO Research Laboratory/Textron) have designed and fabricated a subscale slagging combustor. This slagging combustor, under test since September 1988, has been yielding important experimental data, while having undergone several design iterations.

Sustainable Energy Solutions Task 4.1 Intelligent Manufacturing of Hybrid Carbon-Glass Fiber-Reinforced Composite Wind Turbine Blades  

SciTech Connect

EXECUTIVE SUMARY In this subtask, the manufacturability of hybrid carbon-glass fiber-reinforced composite wind turbine blades using Vacuum-Assisted Resin Transfer Molding (VARTM) was investigated. The objective of this investigation was to study the VARTM process and its parameters to manufacture cost-effective wind turbine blades with no defects (mainly eliminate dry spots and reduce manufacturing time). A 2.5-dimensional model and a 3-dimensional model were developed to simulate mold filling and part curing under different conditions. These conditions included isothermal and non-isothermal filling, curing of the part during and after filling, and placement of injection gates at different locations. Results from this investigation reveal that the process can be simulated and also that manufacturing parameters can be optimized to eliminate dry spot formation and reduce the manufacturing time. Using computer-based models is a cost-effective way to simulate manufacturing of wind turbine blades. The approach taken herein allows the design of the wind blade manufacturing processes without physically running trial-and-error experiments that are expensive and time-consuming; especially for larger blades needed for more demanding environmental conditions. This will benefit the wind energy industry by reducing initial design and manufacturing costs which can later be passed down to consumers and consequently make the wind energy industry more competitive.

Application of Resin Transfer Molding to the Manufacture of Wind Turbine Blade Substructures. Final Report  

DOE Green Energy (OSTI)

The U.S. has generally lacked the capability for an iterative process of detailed structural design, manufacturing, and testing at the full blade level to achieve specific structural performance, cost, and weight targets. This project examined the effects that different composites processing methods had on the performance of representative blade substructures. In addition, the results of the testing of these substructures was used to validate NuMAD, the design tool developed at Sandia National Laboratories.

Simulation of the Manufacturing of Non-Crimp Fabric-Reinforced Composite Wind Turbine Blades to Predict the Formation of Wave Defects  

SciTech Connect

NCFs (Non-Crimp Fabrics) are commonly used in the design of wind turbine blades and other complex systems due to their ability to conform to complex shapes without the wrinkling that is typically experienced with woven fabrics or prepreg tapes. In the current research, a form of vacuum assisted resin transfer molding known as SCRIMP registered is used to manufacture wind turbine blades. Often, during the compacting of the fabric layers by the vacuum pressure, several plies may bunch together out-of-plane and form wave defects. When the resin is infused, the areas beneath the waves become resin rich and can compromise the structural integrity of the blade. A reliable simulation tool is valuable to help predict where waves and other defects may appear as a result of the manufacturing process. Forming simulations often focus on the in-plane shearing and tensile behavior of fabrics and do not necessarily consider the bending stiffness of the fabrics, which is important to predict the formation of wrinkles and/or waves. This study incorporates experimentally determined in-plane shearing, tensile, and bending stiffness information of NCFs into a finite element model (ABAQUS/Explicit) of a 9-meter wind turbine blade to investigate the mechanical behaviors that can lead to the formation of waves as a result of the manufacturing process.

Feasibility studies to establish at the Kazakhstan Ulba metallurgical plant the manufacturing capability to produce low-enriched uranium certified reference materials  

SciTech Connect

One of the salient features of the transition plan that the United States Department of Energy/National Nuclear Security Administration (DOE/NNSA) is presently implementing in the Former Soviet Union countries is the availability of uranium certified reference materials for calibration of nondestructive assay (NDA) measurement equipment. To address this challenge, DOE/NNSA and U.S. national laboratories have focused their cooperative efforts on establishing a reliable source for manufacturing, certifying, and supplying of such standards. The Ulba Metallurgical Plant (UMP), Kazakhstan, which processes large quantities of low-enriched uranium to produce ceramic fuel pellets for nuclear-powered reactors, is well situated to become a key supplier of low-enriched uranium certified reference materials for the country and Central Asia region. We have recently completed Phase I of a feasibility study to establish at UMP capabilities of manufacturing these standards. In this paper we will discuss details of a proposed methodology for uranium down-blending, material selection and characterization, and a proposed methodology of measurement by destructive (DA) and non-destructive (NDA) analysis to form a database for material certification by the competent State authorities in the Republic of Kazakhstan. In addition, we will discuss the prospect for manufacturing of such standards at UMP.

Steam turbine plant  

SciTech Connect

A system for regulating the rate of closing of the turbine intake valve of a steam turbine plant is disclosed. A steam turbine is supplied from a steam generator through a turbine intake valve. A branch line conducts the steam to a bypass valve which is normally closed. In the event of conditions making it necessary to close the turbine intake valve rapidly, a regulator is provided to control the rate of closing of the turbine intake valve and the opening of the bypass valve so that the pressure conditions in the steam generator do not exceed the limits established by the manufacturer. Pressure measuring instruments are placed in the system to sense the pressure immediately upstream from the turbine intake valve and the bypass valve as well as the initial steam supply pressure. These pressure signals are transmitted to a computer which produces a control signal in accordance with predetermined conditions.

Blade Manufacturing Improvement: Remote Blade Manufacturing Demonstration  

DOE Green Energy (OSTI)

The objective of this program was to investigate manufacturing improvements for wind turbine blades. The program included a series of test activities to evaluate the strength, deflection, performance, and loading characteristics of the prototype blades. The original contract was extended in order to continue development of several key blade technologies identified in the project. The objective of the remote build task was to demonstrate the concept of manufacturing wind turbine blades at a temporary manufacturing facility in a rural environment. TPI Composites successfully completed a remote manufacturing demonstration in which four blades were fabricated. The remote demonstration used a manufacturing approach which relied upon material ''kits'' that were organized in the factory and shipped to the site. Manufacturing blades at the wind plant site presents serious logistics difficulties and does not appear to be the best approach. A better method appears to be regional manufacturing facilities, which will eliminate most of the transportation cost, without incurring the logistical problems associated with fabrication directly onsite. With this approach the remote facilities would use commonly available industrial infrastructure such as enclosed workbays, overhead cranes, and paved staging areas. Additional fatigue testing of the M20 root stud design was completed with good results. This design provides adhesive bond strength under fatigue loading that exceeds that of the fastener. A new thru-stud bonding concept was developed for the M30 stud design. This approach offers several manufacturing advantages; however, the test results were inconclusive.

Ceramics for ATS industrial turbines  

DOE Green Energy (OSTI)

US DOE and most US manufacturers of stationary gas turbines are participating in a major national effort to develop advanced turbine systems (ATS). The ATS program will achieve ultrahigh efficiencies, environmental superiority, and cost competitiveness compared with current combustion turbine systems. A major factor in the improved efficiencies of simple cycle ATS gas turbines will be higher operating efficiencies than curren engines. These temperatures strain the limits of metallic alloy and flow-path cooling technologies. Ceramics materials offer a potential alterative to cooled turbine alloys for ATS turbines due to higher melting points than metallics. This paper evaluates ceramics technology and plant economic issues for ATS industrial turbine systems. A program with the objective of demonstrating first-stage ceramic vanes in a commerical industrial turbine is also described.

Blade Manufacturing Improvement Project: Final Report  

SciTech Connect

The Blade Manufacturing Improvement Project explores new, unique and improved materials integrated with innovative manufacturing techniques that promise substantial economic enhancements for the fabrication of wind turbine blades. The primary objectives promote the development of advanced wind turbine blade manufacturing in ways that lower blade costs, cut rotor weight, reduce turbine maintenance costs, improve overall turbine quality and increase ongoing production reliability. Foam Matrix (FMI) has developed a wind turbine blade with an engineered foam core, incorporating advanced composite materials and using Resin Transfer Molding (RTM) processes to form a monolithic blade structure incorporating a single molding tool. Patented techniques are employed to increase blade load bearing capability and insure the uniform quality of the manufactured blade. In production quantities, FMI manufacturing innovations may return a sizable per blade cost reduction when compared to the cost of producing comparable blades with conventional methods.

Fluid turbine  

SciTech Connect

A fluid turbine designed for increased power output includes an annular housing provided with a semi-spherical dome for directing incoming fluid flow to impinge on a plurality of rotor blades within the housing fixed to a vertical output shaft. An angle on the order of between 5 to 85/sup 0/, in the direction of rotation of the shaft, exists between the upper (Leading) and lower (Trailing) edges of each blade. The blades are manufactured from a plurality of aerodynamically-shaped, radially spaced ribs covered with a skin. The leading edge of each rib is curved, while the trailing edge is straight. The straight edge of the ribs in each blade approach a vertical plane through the vertical axis of the housing output shaft as the ribs progress radially inwardly towards the output shaft. The housing has fluid exit passages in its base so that deenergized fluid can be quickly flushed from the housing by the downwardly directed flow in combination with the novel blade configuration, which acts as a screw or force multiplier, to expel deenergized fluid. The airfoil shaped ribs also provide the blades with a contour for increasing the fluid velocity on the underside of the blades adjacent the fluid exit passage to aid in expelling the deenergized air while providing the turbine with both impulse and axial-flow, fluid impingement on the blades, resulting in a force vector of increased magnitude. A downwardly directed, substantially semi-cylindrical deflector frame connected to the housing blocks the path of flow of ambient fluid to create a low pressure area beneath the base to aid in continuously drawing fluid into the housing at high velocity to impinge on the rotor blades. The increased flow velocity and force on the blades along with the enhanced removal of deenergized fluid results in increased power output of the turbine.

Life Cycle Environmental Impacts Resulting from the Manufacture of the Heliostat Field for a Reference Power Tower Design in the United States: Preprint  

SciTech Connect

Life cycle assessment (LCA) is recognized as a useful analytical approach for quantifying environmental impacts of renewable energy technologies, including concentrating solar power (CSP). An LCA accounts for impacts from all stages in the development, operation, and decommissioning of a CSP plant, including such upstream stages as the extraction of raw materials used in system components, manufacturing of those components, and construction of the plant. The National Renewable Energy Laboratory is conducting a series of LCA studies for various CSP technologies. This paper contributes to a thorough LCA of a 100 MWnet molten salt power tower CSP plant by estimating the environmental impacts resulting from the manufacture of heliostats. Three life cycle metrics are evaluated: greenhouse gas emissions, water consumption, and cumulative energy demand. The heliostat under consideration (the 148 m2 Advanced Thermal Systems heliostat) emits 5,300 kg CO2eq, consumes 274 m3 of water, and requires 159,000 MJeq during its manufacture. Future work will incorporate the results from this study into the LCA model used to estimate the life cycle impacts of the entire 100 MWnet power tower CSP plant.

Gas turbines face new challenges  

SciTech Connect

Gas turbines continue to increase the electric power generation market in both the peaking and the intermediate load categories. With the increase in unit size and operating efficiencies. capital costs per kilowatt are reduced. Clean fuels---gas, light oil, or alcohol-type fuel--are needed for the gas turbines. The most efficient method of power generation is now attained from gas turbines, but the shortage of clean fuels looms. Manufacturers are anticipating the availability of clean fuels and continue working on the development of high- pressure, high-temperature turbines. In the near-term, increased efficiency is sought by making use of the turbine exhaust heat. involving combined or regenerative cycles. (MCW)

3) Turbine manufacturer profitability, which can impact turbine prices independently of costs; and 4) Turbine design, which for the purpose of this analysis is principally manifested through increased turbine size. The other three drivers analyzed in this study can be considered exogenous influences, in that they can impact wind turbine costs but fall mostly outside of the direct control of the wind industry. These exogenous drivers include changes in: 5) Raw materials prices, which affect the cost of inputs to the manufacturing process; 6) Energy prices, which impact the cost of manufacturing and transporting turbines; and 7) Foreign exchange rates, which can impact the dollar amount paid for turbines and components imported into the United States.

21st century advanced hydropower turbine system  

DOE Green Energy (OSTI)

While hydropower turbine manufacturers have incrementally improved turbine technology to increase efficiency, the basic design concepts haven`t changed for decades. These late 19th and early 20th century designs did not consider environmental effects, since little was known about environmental effects of hydropower at the time. The U.S. Department of Energy (DOE) and the hydropower industry recognize that hydropower plants have an effect on the environment and there is a great need to bring turbine designs into the 21st century. DOE has issued a request for proposals (RFP) that requested proposers to discard conventional thinking, search out innovative solutions, and to visualize innovative turbines designed from a new perspective. This perspective would look at the {open_quotes}turbine system{close_quotes} (intake to tailrace) which will balance environmental, technical, and economic considerations. This paper describes the DOE Advanced Hydropower Turbine System Program.

Understanding Trends in Wind Turbine Prices Over the Past Decade  

SciTech Connect

Taking a bottom-up approach, this report examines seven primary drivers of wind turbine prices in the United States, with the goal of estimating the degree to which each contributed to the doubling in turbine prices from 2002 through 2008, as well as the subsequent decline in prices through 2010 (our analysis does not extend into 2011 because several of these drivers are best gauged on a full-year basis due to seasonality issues). The first four of these drivers can be considered, at least to some degree, endogenous influences – i.e., those that are largely within the control of the wind industry – and include changes in: 1) Labor costs, which have historically risen during times of tight turbine supply; 2) Warranty provisions, which reflect technology performance and reliability, and are most often capitalized in turbine prices; 3) Turbine manufacturer profitability, which can impact turbine prices independently of costs; and 4) Turbine design, which for the purpose of this analysis is principally manifested through increased turbine size. The other three drivers analyzed in this study can be considered exogenous influences, in that they can impact wind turbine costs but fall mostly outside of the direct control of the wind industry. These exogenous drivers include changes in: 5) Raw materials prices, which affect the cost of inputs to the manufacturing process; 6) Energy prices, which impact the cost of manufacturing and transporting turbines; and 7) Foreign exchange rates, which can impact the dollar amount paid for turbines and components imported into the United States.

Advanced turbine systems program  

SciTech Connect

In accordance with the goals of the DOE program, improvements in the gas turbine are the primary focus of Allison activity during Phase I. To this end Allison conducted a survey of potentially applicable gas turbine cycles and selected the advanced combined cycle as reference system. Extensive analysis of two versions of the advanced combined cycle was performed against the requirement for a 60% thermal efficiency (LHV) utility-sized, natural gas fired system. This analysis resulted in technology requirements for this system. Additional analysis determined emissions potential for the system, established a coal-fueled derivative system and a commercialization plan. This report deals with the technical requirements for a system that meets the thermal efficiency goal. Allison initially investigated four basic thermodynamic cycles: Humid air turbine, intercalate-recuperated systems, advanced combined cycle, chemically recuperated cycle. Our survey and cycle analysis indicated that au had the potential of reaching 60% thermal efficiency. We also concluded that engine hot section technology would be a critical technology regardless of which cycle was chosen. Based on this result Allison chose to concentrate on the advanced combined cycle. This cycle is well known and understood by the utility turbine user community and is therefore likely to be acceptable to users.

To this end Allison conducted a survey of potentially applicable gas turbine cycles and selected the advanced combined cycle as reference system. Extensive analysis of two versions of the advanced combined cycle was performed against the requirement for a 60% thermal efficiency (LHV) utility-sized, natural gas fired system. This analysis resulted in technology requirements for this system. Additional analysis determined emissions potential for the system, established a coal-fueled derivative system and a commercialization plan. This report deals with the technical requirements for a system that meets the thermal efficiency goal. Allison initially investigated four basic thermodynamic cycles: Humid air turbine, intercalate-recuperated systems, advanced combined cycle, chemically recuperated cycle. Our survey and cycle analysis indicated that au had the potential of reaching 60% thermal efficiency. We also concluded that engine hot section technology would be a critical technology regardless of which cycle was chosen. Based on this result Allison chose to concentrate on the advanced combined cycle. This cycle is well known and understood by the utility turbine user community and is therefore likely to be acceptable to users.

Industrial type gas turbines for offshore applications  

SciTech Connect

The paper discusses, with reference to the power generating gas turbines on the FRIGG TCP-2 platform, the specific and general requirements for offshore gas turbine, and how those sometimes conflicting requirements are met. Furthermore, interesting details of the particular installation on the FRIGG TCP-2 platform are described. The gas turbines on the FRIGG TCP-2 platform are the first ones to be installed in Norwegian water after the Norwegian regulations for ''Production and auxiliary systems on production installations, etc.'' were officially issued in April 1978. Some of these special regulations and their influence on the gas turbine design are discussed. Paper No. 79-GT-105.

PowerJet Wind Turbine Project  

SciTech Connect

PROJECT OBJECTIVE The PowerJet wind turbine overcomes problems characteristic of the small wind turbines that are on the market today by providing reliable output at a wide range of wind speeds, durability, silent operation at all wind speeds, and bird-safe operation. Prime Energy�s objective for this project was to design and integrate a generator with an electrical controller and mechanical controls to maximize the generation of electricity by its wind turbine. The scope of this project was to design, construct and test a mechanical back plate to control rotational speed in high winds, and an electronic controller to maximize power output and to assist the base plate in controlling rotational speed in high winds. The test model will continue to operate beyond the time frame of the project, with the ultimate goal of manufacturing and marketing the PowerJet worldwide. Increased Understanding of Electronic & Mechanical Controls Integrated With Electricity Generator The PowerJet back plate begins to open as wind speed exceeds 13.5 mps. The pressure inside the turbine and the turbine rotational speed are held constant. Once the back plate has fully opened at approximately 29 mps, the controller begins pulsing back to the generator to limit the rotational speed of the turbine. At a wind speed in excess of 29 mps, the controller shorts the generator and brings the turbine to a complete stop. As the wind speed subsides, the controller releases the turbine and it resumes producing electricity. Data collection and instrumentation problems prevented identification of the exact speeds at which these events occur. However, the turbine, controller and generator survived winds in excess of 36 mps, confirming that the two over-speed controls accomplished their purpose. Technical Effectiveness & Economic Feasibility Maximum Electrical Output The output of electricity is maximized by the integration of an electronic controller and mechanical over-speed controls designed and tested during the course of this project. The output exceeds that of the PowerJet�s 3-bladed counterparts (see Appendix). Durability All components of the PowerJet turbine assembly�including the electronic and mechanical controls designed, manufactured and field tested during the course of this project�proved to be durable through severe weather conditions, with constant operation and no interruption in energy production. Low Cost Materials for the turbine, generator, tower, charge controllers and ancillary parts are available at reasonable prices. Fabrication of these parts is also readily available worldwide. The cost of assembling and installing the turbine is reduced because it has fewer parts and requires less labor to manufacture and assemble, making it competitively priced compared with turbines of similar output manufactured in the U.S. and Europe. The electronic controller is the unique part to be included in the turbine package. The controllers can be manufactured in reasonably-sized production runs to keep the cost below $250 each. The data logger and 24 sensors are for research only and will be unnecessary for the commercial product. Benefit To Public The PowerJet wind-electric system is designed for distributed wind generation in 3 and 4 class winds. This wind turbine meets DOE�s requirements for a quiet, durable, bird-safe turbine that eventually can be deployed as a grid-connected generator in urban and suburban settings. Results As described more fully below and illustrated in the Appendices, the goals and objectives outlined in 2060 SOPO were fully met. Electronic and mechanical controls were successfully designed, manufactured and integrated with the generator. The turbine, tower, controllers and generators operated without incident throughout the test period, surviving severe winter and summer weather conditions such as extreme temperatures, ice and sustained high winds. The electronic controls were contained in weather-proof electrical boxes and the elec

Wind turbine  

DOE Patents (OSTI)

A wind turbine of the type having an airfoil blade (15) mounted on a flexible beam (20) and a pitch governor (55) which selectively, torsionally twists the flexible beam in response to wind turbine speed thereby setting blade pitch, is provided with a limiter (85) which restricts unwanted pitch change at operating speeds due to torsional creep of the flexible beam. The limiter allows twisting of the beam by the governor under excessive wind velocity conditions to orient the blades in stall pitch positions, thereby preventing overspeed operation of the turbine. In the preferred embodiment, the pitch governor comprises a pendulum (65,70) which responds to changing rotor speed by pivotal movement, the limiter comprising a resilient member (90) which engages an end of the pendulum to restrict further movement thereof, and in turn restrict beam creep and unwanted blade pitch misadjustment.

On the Fatigue Analysis of Wind Turbines  

DOE Green Energy (OSTI)

Modern wind turbines are fatigue critical machines that are typically used to produce electrical power from the wind. Operational experiences with these large rotating machines indicated that their components (primarily blades and blade joints) were failing at unexpectedly high rates, which led the wind turbine community to develop fatigue analysis capabilities for wind turbines. Our ability to analyze the fatigue behavior of wind turbine components has matured to the point that the prediction of service lifetime is becoming an essential part of the design process. In this review paper, I summarize the technology and describe the ''best practices'' for the fatigue analysis of a wind turbine component. The paper focuses on U.S. technology, but cites European references that provide important insights into the fatigue analysis of wind turbines.

GAS TURBINES  

E-Print Network (OSTI)

In the age of volatile and ever increasing natural gas fuel prices, strict new emission regulations and technological advancements, modern IGCC plants are the answer to growing market demands for efficient and environmentally friendly power generation. IGCC technology allows the use of low cost opportunity fuels, such as coal, of which there is a more than a 200-year supply in the U.S., and refinery residues, such as petroleum coke and residual oil. Future IGCC plants are expected to be more efficient and have a potential to be a lower cost solution to future CO2 and mercury regulations compared to the direct coal fired steam plants. Siemens has more than 300,000 hours of successful IGCC plant operational experience on a variety of heavy duty gas turbine models in Europe and the U.S. The gas turbines involved range from SGT5-2000E to SGT6-3000E (former designations are shown on Table 1). Future IGCC applications will extend this experience to the SGT5-4000F and SGT6-4000F/5000F/6000G gas turbines. In the currently operating Siemens ’ 60 Hz fleet, the SGT6-5000F gas turbine has the most operating engines and the most cumulative operating hours. Over the years, advancements have increased its performance and decreased its emissions and life cycle costs without impacting reliability. Development has been initiated to verify its readiness for future IGCC application including syngas combustion system testing. Similar efforts are planned for the SGT6-6000G and SGT5-4000F/SGT6-4000F models. This paper discusses the extensive development programs that have been carried out to demonstrate that target emissions and engine operability can be achieved on syngas operation in advanced F-class 50 Hz and 60 Hz gas turbine based IGCC applications.

Advanced coal-fueled gas turbine systems  

SciTech Connect

Several technology advances since the early coal-fueled turbine programs that address technical issues of coal as a turbine fuel have been developed in the early 1980s: Coal-water suspensions as fuel form, improved methods for removing ash and contaminants from coal, staged combustion for reducing NO{sub x} emissions from fuel-bound nitrogen, and greater understanding of deposition/erosion/corrosion and their control. Several Advanced Coal-Fueled Gas Turbine Systems programs were awarded to gas turbine manufacturers for for components development and proof of concept tests; one of these was Allison. Tests were conducted in a subscale coal combustion facility and a full-scale facility operating a coal combustor sized to the Allison Model 501-K industrial turbine. A rich-quench-lean (RQL), low nitrogen oxide combustor design incorporating hot gas cleanup was developed for coal fuels; this should also be applicable to biomass, etc. The combustor tests showed NO{sub x} and CO emissions {le} levels for turbines operating with natural gas. Water washing of vanes from the turbine removed the deposits. Systems and economic evaluations identified two possible applications for RQL turbines: Cogeneration plants based on Allison 501-K turbine (output 3.7 MW(e), 23,000 lbs/hr steam) and combined cycle power plants based on 50 MW or larger gas turbines. Coal-fueled cogeneration plant configurations were defined and evaluated for site specific factors. A coal-fueled turbine combined cycle plant design was identified which is simple, compact, and results in lower capital cost, with comparable efficiency and low emissions relative to other coal technologies (gasification, advanced PFBC).

LIST/BMI Turbines Instrumentation and Infrastructure  

E-Print Network (OSTI)

In support of two major SNL programs, the Long-term Inflow and Structural Test (LIST) program and the Blade Manufacturing Initiative (BMI), three Micon 65/13M wind turbines have been erected at the USDA Agriculture Research Service (ARS) center in Bushland, Texas. The inflow and structural response of these turbines are being monitored with an array of 60 instruments: 34 to characterize the inflow, 19 to characterize structural response and 7 to characterize the time-varying state of the turbine. The primary characterization of the inflow into the LIST turbine relies upon an array of five sonic anemometers. Primary characterization of the structural response of the turbine uses several sets of strain gauges to measure bending loads on the blades and the tower and two accelerometers to measure the motion of the nacelle. Data are sampled at a rate of 30 Hz using a newly developed data acquisition system. The system features a time-synchronized continuous data stream and telemetered data from the turbine rotor. This paper documents the instruments and infrastructure that have been developed to monitor these turbines and their inflow.

Plan for an Advanced Turbine Systems Program  

Science Conference Proceedings (OSTI)

A draft version of this paper was presented at the Clemson Clean, affordable, and reliable natural gas utilization technologies will play a growing role in meeting future power generation needs in the United States. The US Department of Energy's (DOE) National Energy Strategy projected that total demand for natural gas will rise from 18.5 trillion cubic feet (tcf) in 1990 to 24.2 tcf by the year 2000. Much of this increase is attributed to the increased use of natural gas as a fuel for electric power generation. Candidate technologies for gas fired power generation include gas turbine and fuel cell systems. The first workshop on research needs for advanced gas turbine systems for power generation was held on April 8-10, 1991 in Greenville, South Carolina. The goals of the Clemson-I Workshop were to identify research needs which would accelerate the development of advanced gas turbines and to consider new approaches to implement this research. The Clemson-I Workshop focused on advanced gas turbine systems which would have a lower cost of electricity or better environmental performance than systems currently under development. The workshop was cosponsored by the DOE's Morgantown Energy Technology Center (METC), Clemson University, and the South Carolina Energy Research and Development Center. The proceedings from the workshop have been published. The 75 participants in the Clemson-I Workshop represented a broad spectrum of the gas turbine Research Development (R D) community as well as potential users of advanced gas turbines. Gas turbine manufacturers, the electric utility industry, the university community, as well as government and private sector R D sponsors were represented. Participants in the Clemson-I Workshop concluded that it is technically feasible to develop advanced turbine systems and that Government participation would accelerate the developmental effort. Advanced turbine systems could be operated on natural gas or adapted to coal or biomass firing.

Flow Characteristics Analysis of Widows' Creek Type Control Valve for Steam Turbine Control  

Science Conference Proceedings (OSTI)

The steam turbine converts the kinetic energy of steam to mechanical energy of rotor blades in the power conversion system of fossil and nuclear power plants. The electric output from the generator of which the rotor is coupled with that of the steam turbine depends on the rotation velocity of the steam turbine bucket. The rotation velocity is proportional to the mass flow rate of steam entering the steam turbine through valves and nozzles. Thus, it is very important to control the steam mass flow rate for the load following operation of power plants. Among various valves that control the steam turbine, the control valve is most significant. The steam flow rate is determined by the area formed by the stem disk and the seat of the control valve. While the ideal control valve linearly controls the steam mass flow rate with its stem lift, the real control valve has various flow characteristic curves pursuant to the stem lift type. Thus, flow characteristic curves are needed to precisely design the control valves manufactured for the operating conditions of nuclear power plants. OMEGA (Optimized Multidimensional Experiment Geometric Apparatus) was built to experimentally study the flow characteristics of steam flowing inside the control valve. The Widows' Creek type control valve was selected for reference. Air was selected as the working fluid in the OMEGA loop to exclude the condensation effect in this simplified approach. Flow characteristic curves were plotted by calculating the ratio of the measured mass flow rate versus the theoretical mass flow rate of the air. The flow characteristic curves are expected to be utilized to accurately design and operate the control valve for fossil as well as nuclear plants. (authors)

Program to develop advanced gas turbine systems  

SciTech Connect

The need for an advanced turbine program for land-based engines has been broadly recognized in light of reductions in military funding for turbines, rapid growth in the sale of gas turbines for utility and industrial usage, and the fierce competition with off-shore manufacturers. Only with Government support can US manufacturers meet rapidly changing market conditions such as increased emissions requirements and lower capital cost requirements. In light of this, ATS planning was requested by Congress in the fiscal year (FY) 92 appropriations and is included in thee Energy Policy Act of 1992. The program budget has increased rapidly, with the FY 94 budget including. over $28 million for ATS program activities. The Natural Gas Strategic Plan and Multi-Year Program Crosscut Plan, 1993--1998, includes the ATS program as part of the overall DOE plan for natural gas-related research and development (R&D) activities. Private sector support for the program is sufficient. Three open meetings have been held during the last 2 years to provide an opportunity for industry suggestions and comments. As the result of a public review of the program plan held June 4, 1993, in Pittsburgh, 46 letters of support were received from industry, academia, and others. Gas turbines represent the fastest growing market segment in electrical and cogeneration markets, with over 60 percent of recent installations based on gas turbines. Gas turbine systems offer low installation and operating costs, low emissions (currently with add-on equipment for non-attainment areas), and quick installation (1--2 years). According to the Annual Energy Outlook 1993, electricity and natural gas demand should both grow substantially through 2010. Natural gas-fired gas turbine systems continue to be the prime candidates for much of both new and retrofit capacity in this period. Emissions requirements continue to ratchet downward with single-digit NO{sub x} ppM required in several non-attainment areas in the US

Adaptive simulation of gas turbine performance  

SciTech Connect

A method is presented allowing the simulation of gas turbine performance with the possibility of adapting to engine particularities. Measurements along the gas path are used, in order to adapt a given performance model by appropriate modification of the component maps. The proposed method can provide accurate simulation for engines of the same type, differing due to manufacturing or assembly tolerances. It doesn't require accurate component maps, as they are derived during the adaptation process. It also can be used for health monitoring purposes, introducing thus a novel approach for component condition assessment. The effectiveness of the proposed method is demonstrated by application to an industrial gas turbine.

Turbine power plant system  

SciTech Connect

A turbine power plant system consisting of three sub-systems; a gas turbine sub-system, an exhaust turbine sub-system, and a steam turbine sub-system. The three turbine sub-systems use one external fuel source which is used to drive the turbine of the gas turbine sub-system. Hot exhaust fluid from the gas turbine sub-system is used to drive the turbines of the exhaust turbine sub-system and heat energy from the combustion chamber of the gas turbine sub-system is used to drive the turbine of the steam turbine sub-system. Each sub-system has a generator. In the gas turbine sub-system, air flows through several compressors and a combustion chamber and drives the gas turbine. In the exhaust turbine sub-system, hot exhaust fluid from the gas turbine sub-system flows into the second passageway arrangement of first and fourth heat exchangers and thus transfering the heat energy to the first passageway arrangement of the first and fourth heat exchangers which are connected to the inlets of first and second turbines, thus driving them. Each turbine has its own closed loop fluid cycle which consists of the turbine and three heat exchangers and which uses a fluid which boils at low temperatures. A cooler is connected to a corresponding compressor which forms another closed loop system and is used to cool the exhaust fluid from each of the two above mentioned turbines. In the steam turbine sub-system, hot fluid is used to drive the steam turbine and then it flows through a fluid duct, to a first compressor, the first fluid passageway arrangement of first and second heat exchangers, the second passageway of the first heat exchanger, the combustion chamber of the gas turbine where it receives heat energy, and then finally to the inlet of the steam turbine, all in one closed loop fluid cycle. A cooler is connected to the second passageway of the second heat exchanger in a closed loop fluid cycle, which is used to cool the turbine exhaust.

Wind power manufacturing and supply chain summit USA.  

Science Conference Proceedings (OSTI)

The area of wind turbine component manufacturing represents a business opportunity in the wind energy industry. Modern wind turbines can provide large amounts of electricity, cleanly and reliably, at prices competitive with any other new electricity source. Over the next twenty years, the US market for wind power is expected to continue to grow, as is the domestic content of installed turbines, driving demand for American-made components. Between 2005 and 2009, components manufactured domestically grew eight-fold to reach 50 percent of the value of new wind turbines installed in the U.S. in 2009. While that growth is impressive, the industry expects domestic content to continue to grow, creating new opportunities for suppliers. In addition, ever-growing wind power markets around the world provide opportunities for new export markets.

Annual Report: Turbines (30 September 2012)  

SciTech Connect

The FY12 NETL-RUA Turbine Thermal Management effort supported the Department of Energy (DOE) Hydrogen Turbine Program through conduct of novel, fundamental, basic, and applied research in the areas of aerothermal heat transfer, coatings development, and secondary flow control. This research project utilized the extensive expertise and facilities readily available at NETL and the participating universities. The research approach includes explorative studies based on scaled models and prototype coupon tests conducted under realistic high-temperature, pressurized, turbine operating conditions. This research is expected to render measurable outcomes that will meet DOE advanced turbine development goals of a 3- to 5-point increase in power island efficiency and a 30 percent power increase above the hydrogen-fired combined cycle baseline. In addition, knowledge gained from this project will further advance the aerothermal cooling and TBC technologies in the general turbine community. This project has been structured to address ? Development and design of aerothermal and materials concepts in FY12-13. ? Design and manufacturing of these advanced concepts in FY13. ? Bench-scale/proof-of-concept testing of these concepts in FY13-14 and beyond. The Turbine Thermal Management project consists of four tasks that focus on a critical technology development in the areas of aerothermal and heat transfer, coatings and materials development, design integration and testing, and a secondary flow rotating rig.

Automotive turbine engine  

SciTech Connect

Gas flow through a turbine is divided, with part of the flow directed to the compressor for the combusion chamber and part directed to the primary power turbine. Division of the gas flow is accomplished by a mixing wheel of novel design. Before passing to the primary power turbine the gas flow passes through a secondary power turbine that drives the compressor for the combustion chamber. Both the secondary power turbine and the compressor rotate independently of the main turbine rotor shaft. The power input to the secondary power turbine is varied in accordance with the pressure differential between the gas pressure at the outlet of the compressor for the combustion chamber and the outlet from the mixing wheel. If the speed of the main turbine shaft slows down more power is put into the secondary power turbine and the combustion chamber compressor is speeded up so as to produce a higher gas pressure than would otherwise be the case.

DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines DOE Technology Successes - "Breakthrough" Gas Turbines For years, gas turbine manufacturers faced a barrier that, for all practical purposes, capped power generating efficiencies for turbine-based power generating systems. The barrier was temperature. Above 2300 degrees F, available cooling technologies were insufficient to protect the turbine blades and other internal components from heat degradation. Since higher temperatures are the key to higher efficiencies, this effectively limited the generating efficiency at which a turbine power plant could convert the energy in the fuel into electricity. The Department of Energy's Office of Fossil Energy took on the challenge of turbine temperatures in 1992, and nine years later, its private sector

Advanced turbine systems program overview  

SciTech Connect

The US Department of Energy`s (DOE) Office of Fossil Energy and Office of Energy Efficiency & Renewable Energy are jointly supporting a program to develop Advanced Turbine Systems (ATS). Demonstrations of commercial prototypes will be completed by the year 2000 for both utility- and industrial-scale applications. The program is primarily directed toward natural gas utilization, but eventual application of the technology to coal-fired systems is not overlooked. In major procurements, contractors are required to address (in paper studies though not in testing) the eventual adaptation of their systems to coal firing. Implementation of the program is proceeding well. Phase 1 systems studies have been completed, and Phase 2 concept development has been underway for about a year. Release of solicitation for Phase 3 proposals has been announced for July, 1994. This phase of the program will see teams led by turbine manufacturers move into full scale testing of critical components. Generic research and development has been proceeding in parallel with the major development effort. METC has started testing in their Advanced Turbine Combustion test facility, and Oak Ridge National Laboratory has initiated a materials test program. The industry/university consortium established by the South Carolina Energy Research and Development Center has completed their second round of university awards, with 23 university projects now underway.

Design of high-efficiency turbomachinery and gas turbines  

SciTech Connect

The present treatment of pump, compressor, and turbine turbomachinery emphasizes thermodynamics, design methods, and the use that can be made of relatively simple rules for the choosing of cycle types, vector diagrams, blading types, heat exchanger configurations, etc. Gas dynamics are treated to the virtual exclusion of mechanical design considerations, although a brief historical account of the family of turbomachine systems notes gradual structural as well as thermodynamic and gas dynamic refinements. The complete systems described and analyzed include aircraft, marine, and electrical power generation gas turbines, steam turbines, and hydraulic pumps and turbines. Both axial and centrifugal flow turbomachine types are considered. 112 references.

Stationary turbine component with laminated skin  

DOE Patents (OSTI)

A stationary turbine engine component, such as a turbine vane, includes a internal spar and an external skin. The internal spar is made of a plurality of spar laminates, and the external skin is made of a plurality of skin laminates. The plurality of skin laminates interlockingly engage the plurality of spar laminates such that the external skin is located and held in place. This arrangement allows alternative high temperature materials to be used on turbine engine components in areas where their properties are needed without having to make the entire component out of such material. Thus, the manufacturing difficulties associated with making an entire component of such a material and the attendant high costs are avoided. The skin laminates can be made of advanced generation single crystal superalloys, intermetallics and refractory alloys.

Improving steam turbine-gas turbine plants  

SciTech Connect

Leningrad Polytechnic Institute investigated the main characteristics of combined plants according to their structure, determined by very important parameters. The following parameters were selected: utilization factor (ratio of heat added to the steam-water working medium from the heat of the exhaust gases to the entire amount of heat added to the steam-water working medium) and fuel consumption factor (ratio of heat from fuel added to the steam-water working medium to the entire consumption of heat in the combined plant). It is concluded that steam turbine-gas turbine plants working at comparatively low gas temperatures (about 800/sup 0/C) must be constructed as plants of maximum capacity, i.e., with large steam flows. Gas turbine-steam turbine plants with high-temperature gas turbines operating at a high utilization factor (approaching binary plants) ensure a qualitative rise in efficiency and have high flexibility characteristics. They are the most promising power plants. A long-term plan for development of combined plants on the basis of standard steam turbine and gas turbine equipment, the production of which is planned in the USSR and in Comecon countries, is required. This plan must be closely connected with solution of the problem of using coals for gas turbine plants.

Geothermal turbine installation  

SciTech Connect

A geothermal turbine intallation in which high-pressure steam is separated from geothermal steam, which is a mixture of steam and water, with the high pressure steam connected to a high pressure turbine. Low pressure steam produced by flashing the hot water component of the geothermal steam is introduced to a low pressure turbine which is constructed and operates independently of the high pressure turbine. The discharge steam from the high pressure turbine is introduced to a steam condenser operating at a low vacuum while discharge steam from the low pressure turbine is introduced into a steam condenser operating at a high vacuum. The cooling water system of the high and low pressure condensers are connected in series with one another. A maximum power increase is obtained if the flow rates of the high and low pressure steams at the extraction ports of the high and low pressure turbines are made substantially equal to one another.

Understanding Trends in Wind Turbine Prices Over the Past Decade

Understanding Trends in Wind Turbine Prices Over the Past Decade Understanding Trends in Wind Turbine Prices Over the Past Decade Title Understanding Trends in Wind Turbine Prices Over the Past Decade Publication Type Report Refereed Designation Unknown Year of Publication 2011 Authors Bolinger, Mark, and Ryan H. Wiser Pagination 46 Date Published 10/2011 Publisher LBNL City Berkeley Keywords electricity markets and policy group, energy analysis and environmental impacts department Abstract Berkeley Lab has gathered price data on 81 U.S. wind turbine transactions totaling 23,850 MW announced from 1997 through early 2011. Figure ES-1 depicts these reported wind turbine transaction prices (along with the associated trend line), broken out by the size of the transaction (in MW). Figure ES-1 also presents average (global) turbine prices reported by Vestas for the years 2005 through 2010, as well as a range of reported pricing (among various turbine manufacturers) for transactions signed in 2010 and so far in 2011 (with 2011 prices generally lower than 2010 prices). After hitting a low of roughly $750/kW from 2000 to 2002, average wind turbine prices doubled through 2008, rising to an average of roughly $1,500/kW. Wind turbine prices have since declined substantially, with price quotes for transactions executed in 2010 and to date in 2011 ranging from $900-$1,400/kW depending on the manufacturer and turbine model. For example, turbines designed for lower wind speed sites - deploying higher hub heights and larger rotor diameters for a given nameplate capacity - are priced at the higher end of this range. These quotes suggest price declines of as much as 33% or more since late 2008, with an average decline closer to perhaps 20% for orders announced in 2010 (as opposed to in 2011, which has seen further price declines). These two substantial and opposing wind turbine price trends over the past decade - and particularly the doubling in prices in the 2002-2008 period - run counter to the smooth, gradually declining technology cost trajectories that are often assumed by energy analysts modeling the diffusion of new technologies, including wind power. Understanding and explaining this notable discrepancy between theory and historical reality is the primary motivation for this work. Taking a bottom-up approach, this report examines seven primary drivers of wind turbine prices in the United States, with the goal of estimating the degree to which each contributed to the doubling in turbine prices from 2002 through 2008, as well as the subsequent decline in prices through 2010 (our analysis does not extend into 2011 because several of these drivers are best gauged on a full-year basis due to seasonality issues).

Economics of grid-connected small wind turbines in the domestic market  

DOE Green Energy (OSTI)

Exploitation of certain niche markets for small wind turbines is one strategy that could help speed the commercialization of grid-connected small turbines. The authors review the world's turbine manufacturers, the utility grid-connected applications and selected niche markets for grid-connected small wind systems (0.1 to 100 kilowatts). Wind turbine installation and purchase are handled under three different payment scenarios: paid in full up front, paid through a second mortgage, or paid as part of a first mortgage. The authors used a simple payback method to compare these scenarios and analyze the costs and energy produced for three different U.S. small wind turbines. When there is a buy-down program for the small wind turbine combined with other financial factors such as net metering, tax exemptions, and tax credits, a strong market incentive is created for the use of grid-connected small wind turbines.

Low-NOx combustors reduce peak flame temperatures by mixing fuel and air before combustion and by keeping the fuel-to-air ratio as low (lean) as possible, while still maintaining combustion stability over the broadest possible operating range. Low-NOx combustion systems are inherently more complex than diffusion combustion systems, a fact that impacts operational flexibility, re...

Using Machine Learning to Create Turbine Performance Models (Presentation)  

DOE Green Energy (OSTI)

Wind turbine power output is known to be a strong function of wind speed, but is also affected by turbulence and shear. In this work, new aerostructural simulations of a generic 1.5 MW turbine are used to explore atmospheric influences on power output. Most significant is the hub height wind speed, followed by hub height turbulence intensity and then wind speed shear across the rotor disk. These simulation data are used to train regression trees that predict the turbine response for any combination of wind speed, turbulence intensity, and wind shear that might be expected at a turbine site. For a randomly selected atmospheric condition, the accuracy of the regression tree power predictions is three times higher than that of the traditional power curve methodology. The regression tree method can also be applied to turbine test data and used to predict turbine performance at a new site. No new data is required in comparison to the data that are usually collected for a wind resource assessment. Implementing the method requires turbine manufacturers to create a turbine regression tree model from test site data. Such an approach could significantly reduce bias in power predictions that arise because of different turbulence and shear at the new site, compared to the test site.

Larger Turbines and the Future Cost of Wind Energy (Poster)  

DOE Green Energy (OSTI)

The move to larger turbines has been observed in the United States and around the world. Turbine scaling increases energy capture while reducing general project infrastructure costs and landscape impacts, each of which of can reduce the cost of wind energy. However, scaling in the absence of innovation, can increase turbine costs. The ability of turbine designers and manufacturers to continue to scale turbines, while simultaneously reducing costs, is an important factor in long-term viability of the industry. This research seeks to better understand how technology innovation can allow the continued development of larger turbines on taller towers while also achieving lower cost of energy. Modeling incremental technology improvements identified over the past decade demonstrates that cost reductions on the order of 10%, and capacity factor improvements on the order of 5% (for sites with annual mean wind speed of 7.25 m/s at 50m), are achievable for turbines up to 3.5 MW. However, to achieve a 10% cost reduction and a 10% capacity factor improvement for turbines up to 5 MW, additional technology innovations must be developed and implemented.

Alternative Liquid Fuel Effects on Cooled Silicon Nitride Marine Gas Turbine Airfoils  

Science Conference Proceedings (OSTI)

With prior support from the Office of Naval Research, DARPA, and U.S. Department of Energy, United Technologies is developing and engine environment testing what we believe to be the first internally cooled silicon nitride ceramic turbine vane in the United States. The vanes are being developed for the FT8, an aeroderivative stationary/marine gas turbine. The current effort resulted in further manufacturing and development and prototyping by two U.S. based gas turbine grade silicon nitride component manufacturers, preliminary development of both alumina, and YTRIA based environmental barrier coatings (EBC's) and testing or ceramic vanes with an EBC coating.

Steam Turbine Cogeneration  

E-Print Network (OSTI)

Steam turbines are widely used in most industrial facilities because steam is readily available and steam turbine is easy to operate and maintain. If designed properly, a steam turbine co-generation (producing heat and power simultaneously) system can increase energy efficiency, reduce air emissions and qualify the equipment for a Capital Cost tax Allowance. As a result, such a system benefits the stakeholders, the society and the environment. This paper describes briefly the types of steam turbine classified by their conditions of exhaust and review quickly the fundamentals related to steam and steam turbine. Then the authors will analyze a typical steam turbine co-generation system and give examples to illustrate the benefits of the System.

Economical Condensing Turbines?  

E-Print Network (OSTI)

Steam turbines have long been used at utilities and in industry to generate power. There are three basic types of steam turbines: condensing, letdown and extraction/condensing. • Letdown turbines reduce the pressure of the incoming steam to one or more pressures and generate power very efficiently, assuming that all the letdown steam has a use. Two caveats: Letdown turbines produce power based upon steam requirements and not based upon power requirements, and if all the steam letdown does not have a use, letdown turbines can become a very expensive way of producing electric power. • Condensing turbines have the ability to handle rapid swings in electrical load. Unfortunately, they can only condense a small percentage of the steam, usually less than 14%. Therefore only a small percent of the heat of condensation is available for their use. Also equipment must be used to condense the remaining steam below atmospheric pressure. • Extraction/condensing turbines both extract steam at a useful temperature and pressure and then condense the remainder of the steam. These units have the ability to load follow also. They are often used in concert with gas turbines to produce the balance of electrical power and to keep a electric self generator from drawing electrical power from the grid. The method for analyzing the cost of the condensing steam produced power is exactly the same in all cases. This paper will attempt to provide a frame work for preliminary economic analysis on electric power generation for condensing steam turbines.

Rampressor Turbine Design  

DOE Green Energy (OSTI)

The design of a unique gas turbine engine is presented. The first Rampressor Turbine engine rig will be a configuration where the Rampressor rotor is integrated into an existing industrial gas turbine engine. The Rampressor rotor compresses air which is burned in a traditional stationary combustion system in order to increase the enthalpy of the compressed air. The combustion products are then expanded through a conventional gas turbine which provides both compressor and electrical power. This in turn produces shaft torque, which drives a generator to provide electricity. The design and the associated design process of such an engine are discussed in this report.

Hermetic turbine generator  

DOE Patents (OSTI)

A Rankine cycle turbine drives an electric generator and a feed pump, all on a single shaft, and all enclosed within a hermetically sealed case. The shaft is vertically oriented with the turbine exhaust directed downward and the shaft is supported on hydrodynamic fluid film bearings using the process fluid as lubricant and coolant. The selection of process fluid, type of turbine, operating speed, system power rating, and cycle state points are uniquely coordinated to achieve high turbine efficiency at the temperature levels imposed by the recovery of waste heat from the more prevalent industrial processes.

Open cycle - OTEC turbine design  

Science Conference Proceedings (OSTI)

The design of a low-pressure, open cycle ocean thermal energy conversion system (OTEC) is described. Near-surface ocean water at 80 F is allowed to expand in a one-half psi evaporator for passage through a turbine cold water (40 F), pumped upward from a 3,000 ft depth, is used to recondense the steam. Plans for a 2.5-3 MWe prototype plant, as a proof-of-principle project for a 100 MWe plant, include seawater pumps driven off the generator shaft, potable water as a by-product of the condensor, ease of access for O and M, and an integrated, gear-driven deaerator system with reinjection into the warm seawater discharge. An inlet flow of 3,000,000 cu ft/sec, a single stage vertical turbine with 40 ft fiber reinforced composite blades, 200 rpm operation on a 65 ft diameter disk, and an overall efficiency of 3% are features of the 100 MWe plant. A flowfield analysis, a velocity triangle analysis, and a structural dynamics analysis are outlined, along with materials applications and manufacturing process considerations in blade design. The 3MWe OTEC will be one-sixth the size of a 100MWe OTEC.

Large heavy-duty gas turbines for base-load power generation and heat cogeneration  

SciTech Connect

The predominant role of large gas turbines has shifted from peaking-load duty to midrange and base-load electric power generation, especially within combined-cycle plants. Such applications require heavy-duty industrial gas turbines to ensure the same high reliability and availability for continuous service as the associated steam turbines. It is also important that the gas turbines be designed for low maintenance to minimize the necessary outage times and costs for component repair and replacement. The basic design principles and applications of Model V94 gas turbines are discussed with special reference to highly reliable and economic bulk power generation.

Advanced Turbine Systems Program and coal applications  

Science Conference Proceedings (OSTI)

The US Department of Energy (DOE) is conducting a program to develop ultra high-efficiency, cost-effective, environmentally benign gas turbine systems for industrial and utility applications. The Advanced Turbine Systems (ATS) Program, jointly managed by the DOE's Office of Fossil Energy (DOE/FE) and Office of Conservation and Renewable Energy (DOE/CE), will lead to the commercial offering by industry of systems meeting full program goals by the years 2000--2002. It is expected that some advanced technology will already have been commercialized in intermediate systems before that time. Teams, led by US turbine manufacturers, will conduct most of the development work in the ATS Program. However, a substantial technology base element of the program see universities and others conduct significant research and development (R D) on generic technology issues relevant to the program. The program is primarily aimed at developing natural gas-fired turbine systems. Although the conversion of ATS to firing with coal or biomass fuels will be addressed in the analysis of ATS, tests will not be conducted in the program to verify conversion to alternate fuel firing. The program will however, include work to transfer advanced technology to the coal- and biomass-fueled systems being developed in other DOE programs.

Advanced turbine systems: Studies and conceptual design  

SciTech Connect

The ABB selection for the Advanced Turbine System (ATS) includes advanced developments especially in the hot gas path of the combustion turbine and new state-of-the-art units such as the steam turbine and the HRSG. The increase in efficiency by more than 10% multiplicative compared to current designs will be based on: (1) Turbine Inlet Temperature Increase; (2) New Cooling Techniques for Stationary and Rotating Parts; and New Materials. Present, projected component improvements that will be introduced with the above mentioned issues will yield improved CCSC turbine performance, which will drive the ATS selected gas-fired reference CC power plant to 6 % LHV or better. The decrease in emission levels requires a careful optimization of the cycle design, where cooling air consumption has to be minimized. All interfaces of the individual systems in the complete CC Plant need careful checks, especially to avoid unnecessary margins in the individual designs. This study is an important step pointing out the feasibility of the ATS program with realistic goals set by DOE, which, however, will present challenges for Phase II time schedule of 18 months. With the approach outlined in this study and close cooperation with DOE, ATS program success can be achieved to deliver low emissions and low cost of electricity by the year 2002. The ABB conceptual design and step approach will lead to early component demonstration which will help accelerate the overall program objectives.

Single rotor turbine engine  

SciTech Connect

There has been invented a turbine engine with a single rotor which cools the engine, functions as a radial compressor, pushes air through the engine to the ignition point, and acts as an axial turbine for powering the compressor. The invention engine is designed to use a simple scheme of conventional passage shapes to provide both a radial and axial flow pattern through the single rotor, thereby allowing the radial intake air flow to cool the turbine blades and turbine exhaust gases in an axial flow to be used for energy transfer. In an alternative embodiment, an electric generator is incorporated in the engine to specifically adapt the invention for power generation. Magnets are embedded in the exhaust face of the single rotor proximate to a ring of stationary magnetic cores with windings to provide for the generation of electricity. In this alternative embodiment, the turbine is a radial inflow turbine rather than an axial turbine as used in the first embodiment. Radial inflow passages of conventional design are interleaved with radial compressor passages to allow the intake air to cool the turbine blades.

Dynamic Models for Wind Turbines and Wind Power Plants  

DOE Green Energy (OSTI)

The primary objective of this report was to develop universal manufacturer-independent wind turbine and wind power plant models that can be shared, used, and improved without any restrictions by project developers, manufacturers, and engineers. Manufacturer-specific models of wind turbines are favored for use in wind power interconnection studies. While they are detailed and accurate, their usages are limited to the terms of the non-disclosure agreement, thus stifling model sharing. The primary objective of the work proposed is to develop universal manufacturer-independent wind power plant models that can be shared, used, and improved without any restrictions by project developers, manufacturers, and engineers. Each of these models includes representations of general turbine aerodynamics, the mechanical drive-train, and the electrical characteristics of the generator and converter, as well as the control systems typically used. To determine how realistic model performance is, the performance of one of the models (doubly-fed induction generator model) has been validated using real-world wind power plant data. This work also documents selected applications of these models.

Steam turbine control  

SciTech Connect

In a power plant which includes a steam turbine with main control valves for admitting steam into the steam turbine and a steam bypass with bypass control valves for diverting steam around the steam turbine directly into a condenser, it is necessary to coordinate the operation of the respective valves so that the steam turbine can be started, brought up to speed, synchronized with a generator and then loaded as smoothly and efficiently as possible. The present invention provides for such operation and, in addition, allows for the transfer of power plant operation from the so-called turbine following mode to the boiler following mode through the use of the sliding pressure concept. The invention described is particularly applicable to combined cycle power plants.

Fish-Friendly Hydropower Turbine Development & Deployment: Alden Turbine Preliminary Engineering and Model Testing  

SciTech Connect

The Alden turbine was developed through the U.S. Department of Energy's (DOE's) former Advanced Hydro Turbine Systems Program (1994-2006) and, more recently, through the Electric Power Research Institute (EPRI) and the DOE's Wind & Water Power Program. The primary goal of the engineering study described here was to provide a commercially competitive turbine design that would yield fish passage survival rates comparable to or better than the survival rates of bypassing or spilling flow. Although the turbine design was performed for site conditions corresponding to 92 ft (28 m) net head and a discharge of 1500 cfs (42.5 cms), the design can be modified for additional sites with differing operating conditions. During the turbine development, design modifications were identified for the spiral case, distributor (stay vanes and wicket gates), runner, and draft tube to improve turbine performance while maintaining features for high fish passage survival. Computational results for pressure change rates and shear within the runner passage were similar in the original and final turbine geometries, while predicted minimum pressures were higher for the final turbine. The final turbine geometry and resulting flow environments are expected to further enhance the fish passage characteristics of the turbine. Computational results for the final design were shown to improve turbine efficiencies by over 6% at the selected operating condition when compared to the original concept. Prior to the release of the hydraulic components for model fabrication, finite element analysis calculations were conducted for the stay vanes, wicket gates, and runner to verify that structural design criteria for stress and deflections were met. A physical model of the turbine was manufactured and tested with data collected for power and efficiency, cavitation limits, runaway speed, axial and radial thrust, pressure pulsations, and wicket gate torque. All parameters were observed to fall within ranges expected for conventional radial flow machines. Based on these measurements, the expected efficiency peak for prototype application is 93.64%. These data were used in the final sizing of the supporting mechanical and balance of plant equipment. The preliminary equipment cost for the design specification is $1450/kW with a total supply schedule of 28 months. This equipment supply includes turbine, generator, unit controls, limited balance of plant equipment, field installation, and commissioning. Based on the selected head and flow design conditions, fish passage survival through the final turbine is estimated to be approximately 98% for 7.9-inch (200-mm) fish, and the predicted survival reaches 100% for fish 3.9 inches (100 mm) and less in length. Note that fish up to 7.9- inches (200 mm) in length make up more than 90% of fish entrained at hydro projects in the United States. Completion of these efforts provides a mechanical and electrical design that can be readily adapted to site-specific conditions with additional engineering development comparable to costs associated with conventional turbine designs.

Foam Cleaning of Steam Turbines  

E-Print Network (OSTI)

The efficiency and power output of a steam turbine can be dramatically reduced when deposits form on the turbine blades. Disassembly and mechanical cleaning of the turbine is very time consuming and costly. Deposits can be removed from the turbine internals in situ by foaming an appropriate cleaning solution and injecting it through the turbine, dissolving the deposits and removing them from the system. Because disassembly of the turbine is not required, foam cleaning is a much faster and more cost-effective method of removing deposits. In recent years, HydroChem has removed copper deposits from over 130 Westinghouse and General Electric turbines nationwide using patented equipment.

An overview of DOE`s wind turbine development programs  

DOE Green Energy (OSTI)

The development of technologically advanced, higher efficiency wind turbines continues to be a high priority activity of the US wind industry. The United States Department of Energy (DOE) is conducting and sponsoring a range of programs aimed at assisting the wind industry with system design, development, and testing. The overall goal is to develop systems that can compete with conventional electric generation for $.05/kWh at 5.8 m/s (13 mph sites) by the mid-1990s and with fossil-fuel-based generators for $.04/kWh at 5.8 m/s sites by the year 2000. These goals will be achieved through several programs. The Value Engineered Turbine Program will promote the rapid development of US capability to manufacture wind turbines with known and well documented records of performance, cost, and reliability, to take advantage of near-term market opportunities. The Advanced Wind Turbine Program will assist US industry to develop and integrate innovative technologies into utility-grade wind turbines for the near-term (mid 1990s) and to develop a new generation of turbines for the year 2000. The collaborative Electric Power Research Institute (EPRI)/DOE Utility Wind Turbine Performance Verification Program will deploy and evaluate commercial-prototype wind turbines in typical utility operating environments, to provide a bridge between development programs currently underway and commercial purchases of utility-grade wind turbines. A number of collaborative efforts also will help develop a range of small systems optimized to work in a diesel hybrid environment to provide electricity for smaller non-grid-connected applications.

Gas turbine plant emissions  

SciTech Connect

Many cogeneration facilities use gas turbines combined with heat recovery boilers, and the number is increasing. At the start of 1986, over 75% of filings for new cogeneration plants included plans to burn natural gas. Depending on the geographic region, gas turbines are still one of the most popular prime movers. Emissions of pollutants from these turbines pose potential risks to the environment, particularly in geographical areas that already have high concentrations of cogeneration facilities. Although environmental regulations have concentrated on nitrogen oxides (NO/sub x/) in the past, it is now necessary to evaluate emission controls for other pollutants as well.

Streamlining blade production would reduce turbine costs  

SciTech Connect

Gas turbine technology's overall future will see continuing increases in both size and higher operating temperatures, each contributing to improved energy conversion efficiency and reduced comparative capital outlay. Manufacturing technology will become even more relevant as blades acquire more sophisticated cooling or adopt the use of exotic refractory material such as crystal fibers and ceramics or both. The trend towards rising temperatures will continue. The incentives are high when it is realized that for every 100/sup 0/C increase in firing temperature there is a gain of approximately 18 percent in machine output and 2.7 percent increase in thermal efficiency.

Operation of a third generation wind turbine  

SciTech Connect

A modern wind turbine was installed on May 26, 1982, at the USDA Conservation and Production Research Laboratory, Bushland, Texas. This wind machine was used to provide electrical energy for irrigation pumping and other agricultural loads. The wind turbine purchased for this research is an Enertech Model 44, manufactured by Enertech Corporation, Norwich, Vermont. The horizontal-axis wind turbine has a 13.4 m diameter, three-bladed, fixed-pitch rotor on a 24.4-m tower. The blades are laminated epoxy-wood, and are attached to a steel hub. A 25-kW induction generator provides 240 V, 60 Hz, single-phase electrical power. The wind turbine operated 64 percent of the time, while being available to operate over 94 percent of the time. The unit had a net energy production of over 80,000 kWh in an average windspeed of 5.9 m/s at a height of 10 m in a 16-month period. The blade pitch was originally offset two degrees from design to maintain power production within the limitations of the gearbox, generator, and brakes. A maximum output of 23.2 kW averaged over a 15-second period indicated that with a new brake, the system was capable of handling more power. After a new brake was installed, the blade pitch was changed to one degree from design. The maximum power output measured after the pitch change was 29.3 kW. Modified blade tip brakes were installed on the wind turbine on July 7, 1983. These tip brakes increased power production at lower windspeeds while reducing power at higher windspeeds.

Investigation of Various Wind Turbine Drivetrain Condition Monitoring Techniques  

SciTech Connect

The wind industry has experienced premature turbine component failures during the past years. With the increase in turbine size, these failures, especially those found in the major drivetrain components, i.e. main shaft, gearbox, and generator, have become extremely costly. Given that the gearbox is the most costly component in the drivetrain to fix, the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC) to determine the causes for premature gearbox failures and subsequently, recommend improvements to gearbox design, manufacture, and operational practices. The GRC has two identical test gearboxes, which are planned for a dynamometer and a field test, respectively.

Turbine blade tip flow discouragers  

SciTech Connect

A turbine assembly comprises a plurality of rotating blade portions in a spaced relation with a stationery shroud. The rotating blade portions comprise a root section, a tip portion and an airfoil. The tip portion has a pressure side wall and a suction side wall. A number of flow discouragers are disposed on the blade tip portion. In one embodiment, the flow discouragers extend circumferentially from the pressure side wall to the suction side wall so as to be aligned generally parallel to the direction of rotation. In an alternative embodiment, the flow discouragers extend circumferentially from the pressure side wall to the suction side wall so as to be aligned at an angle in the range between about 0.degree. to about 60.degree. with respect to a reference axis aligned generally parallel to the direction of rotation. The flow discouragers increase the flow resistance and thus reduce the flow of hot gas flow leakage for a given pressure differential across the blade tip portion so as to improve overall turbine efficiency.

Turbines in the sky  

SciTech Connect

Gas turbines are being investigated as power sources for the proposed Star Wars weapons flatforms. The gas turbine engine offers the best opportunity for exploiting the high-temperature potential of both nuclear and chemical combustion. The use of mature gas turbine technology and existing materials would result in highly reliable PCUs capable of meeting SDI's requirements. However, operation under the temperature limits imposed by existing materials would result in a prohibitively heavy system. Cooled blades would somewhat increase temperature capability; however the turbine's mass, though reduced, would still be unacceptably large. The greatest improvements would result from the ability to operate at temperatures of up to 2000 K, pressures up to 14 MPa, and stress up to 690 MPa.

Reaction Injection Molded 7.5 Meter Wind Turbine Blade  

DOE Green Energy (OSTI)

An optimized small turbine blade (7.5m radius) was designed and a partial section molded with the RIM (reaction-injection molded polymer) process for mass production. The intended market is for generic three-bladed wind turbines, 100 kilowatts or less, for grid-assist end users with rural and semi-rural sites, such as the farm/ranch market, having low to moderate IEC Class 3-4 wind regimes. This blade will have substantial performance improvements over, and be cheaper than, present-day 7.5m blades. This is made possible by the injection-molding process, which yields high repeatability, accurate geometry and weights, and low cost in production quantities. No wind turbine blade in the 7.5m or greater size has used this process. The blade design chosen uses a RIM skin bonded to a braided infused carbon fiber/epoxy spar. This approach is attractive to present users of wind turbine blades in the 5-10m sizes. These include rebladeing California wind farms, refurbishing used turbines for the Midwest farm market, and other manufacturers introducing new turbines in this size range.

Lightning Activities in the DOE-EPRI Turbine Verification Program  

DOE Green Energy (OSTI)

The US Department of Energy (DOE)-Electric Power Research Institute (EPRI) Turbine Verification Program (TVP) has played a vital role in improving the understanding of lightning protection for wind turbines. In response to concerns from host utilities, the TVP began a lightning protection project to study the impact of lightning activity at the 6.0-megawatt (MW) wind power facility in Ft. Davis, Texas. McNiff Light Industry (MLI) and Global Energy Concepts (GEC) established a broad observation and documentation effort to survey the lightning protection methodologies used and to evaluate the damage resulting from lightning activity at the turbines. The 6.05-MW wind power plant in Searsburg, Vermont, was inspected after a severe lightning storm caused damage to several turbines there. Zond, McNiff, and consultants from Lightning Technologies, Inc. conducted post-damage inspections at both sites to develop recommendations for improving lightning protection. Site operators implemented the recommended mitigation strategies, and the turbines were monitored to determine if the protection measures improved project operations. This paper summarizes the experience gained through TVP's lightning-related research, and provides a set of guidelines for wind turbine manufacturers, owners, and operators.

High temperature nuclear gas turbine  

SciTech Connect

Significance of gas turbine cycle, process of the development of gas turbines, cycle and efficiency of high-temperature gas turbines, history of gas turbine plants and application of nuclear gas turbines are described. The gas turbines are directly operated by the heat from nuclear plants. The gas turbines are classified into two types, namely open cycle and closed cycle types from the point of thermal cycle, and into two types of internal combustion and external combustion from the point of heating method. The hightemperature gas turbines are tbe type of internal combustion closed cycle. Principle of the gas turbines of closed cycle and open cycle types is based on Brayton, Sirling, and Ericsson cycles. Etficiency of the turbines is decided only by pressure ratio, and is independent of gas temperature. An example of the turbine cycle for the nuclear plant Gestacht II is explained. The thermal efficiency of that plant attains 37%. Over the gas temperature of about 750 deg C, the thermal efficiency of the gas turbine cycle is better than that of steam turbine cycle. As the nuclear fuel, coated particle fuel is used, and this can attain higher temperature of core outlet gas. Direct coupling of the nuclear power plants and the high temperature gas turbines has possibility of the higher thermal efficiency. (JA)

Low Speed Technology for Small Turbine Development Reaction Injection Molded 7.5 Meter Wind Turbine Blade  

Science Conference Proceedings (OSTI)

An optimized small turbine blade (7.5m radius) was designed and a partial section molded with the RIM (reaction-injection molded polymer) process for mass production. The intended market is for generic three-bladed wind turbines, 100 kilowatts or less, for grid-assist end users with rural and semi-rural sites, such as the farm/ranch market, having low to moderate IEC Class 3-4 wind regimes. This blade will have substantial performance improvements over, and be cheaper than, present-day 7.5m blades. This is made possible by the injection-molding process, which yields high repeatability, accurate geometry and weights, and low cost in production quantities. No wind turbine blade in the 7.5m or greater size has used this process. The blade design chosen uses a RIM skin bonded to a braided infused carbon fiber/epoxy spar. This approach is attractive to present users of wind turbine blades in the 5-10m sizes. These include rebladeing California wind farms, refurbishing used turbines for the Midwest farm market, and other manufacturers introducing new turbines in this size range.

Cost Study for Large Wind Turbine Blades  

SciTech Connect

The cost study for large wind turbine blades reviewed three blades of 30 meters, 50 meters, and 70 meters in length. Blade extreme wind design loads were estimated in accordance with IEC Class I recommendations. Structural analyses of three blade sizes were performed at representative spanwise stations assuming a stressed shell design approach and E-glass/vinylester laminate. A bill of materials was prepared for each of the three blade sizes using the laminate requirements prepared during the structural analysis effort. The labor requirements were prepared for twelve major manufacturing tasks. TPI Composites developed a conceptual design of the manufacturing facility for each of the three blade sizes, which was used for determining the cost of labor and overhead (capital equipment and facilities). Each of the three potential manufacturing facilities was sized to provide a constant annual rated power production (MW per year) of the blades it produced. The cost of the production tooling and overland transportation was also estimated. The results indicate that as blades get larger, materials become a greater proportion of total cost, while the percentage of labor cost is decreased. Transportation costs decreased as a percentage of total cost. The study also suggests that blade cost reduction efforts should focus on reducing material cost and lowering manufacturing labor, because cost reductions in those areas will have the strongest impact on overall blade cost.

Development of environmentally advanced hydropower turbine system design concepts  

DOE Green Energy (OSTI)

A team worked together on the development of environmentally advanced hydro turbine design concepts to reduce hydropower`s impact on the environment, and to improve the understanding of the technical and environmental issues involved, in particular, with fish survival as a result of their passage through hydro power sites. This approach brought together a turbine design and manufacturing company, biologists, a utility, a consulting engineering firm and a university research facility, in order to benefit from the synergy of diverse disciplines. Through a combination of advanced technology and engineering analyses, innovative design concepts adaptable to both new and existing hydro facilities were developed and are presented. The project was divided into 4 tasks. Task 1 investigated a broad range of environmental issues and how the issues differed throughout the country. Task 2 addressed fish physiology and turbine physics. Task 3 investigated individual design elements needed for the refinement of the three concept families defined in Task 1. Advanced numerical tools for flow simulation in turbines are used to quantify characteristics of flow and pressure fields within turbine water passageways. The issues associated with dissolved oxygen enhancement using turbine aeration are presented. The state of the art and recent advancements of this technology are reviewed. Key elements for applying turbine aeration to improve aquatic habitat are discussed and a review of the procedures for testing of aerating turbines is presented. In Task 4, the results of the Tasks were assembled into three families of design concepts to address the most significant issues defined in Task 1. The results of the work conclude that significant improvements in fish passage survival are achievable.

Tutorial of Wind Turbine Control for Supporting Grid Frequency through Active Power Control: Preprint  

DOE Green Energy (OSTI)

As wind energy becomes a larger portion of the world's energy portfolio and wind turbines become larger and more expensive, wind turbine control systems play an ever more prominent role in the design and deployment of wind turbines. The goals of traditional wind turbine control systems are maximizing energy production while protecting the wind turbine components. As more wind generation is installed there is an increasing interest in wind turbines actively controlling their power output in order to meet power setpoints and to participate in frequency regulation for the utility grid. This capability will be beneficial for grid operators, as it seems possible that wind turbines can be more effective at providing some of these services than traditional power plants. Furthermore, establishing an ancillary market for such regulation can be beneficial for wind plant owner/operators and manufacturers that provide such services. In this tutorial paper we provide an overview of basic wind turbine control systems and highlight recent industry trends and research in wind turbine control systems for grid integration and frequency stability.

Applicability of Nacelle Anemometer Measurements for Use in Turbine Power Performance Tests: Preprint  

DOE Green Energy (OSTI)

Collection of accurate wind speed data is one of the more problematic elements in conducting wind turbine power performance tests. IEC 61400-12 specifies meteorological tower placement between two and four rotor diameters upwind of the test turbine. However, use of an upwind meteorological tower can be difficult at some sites. In some cases, complex terrain near the turbine may make placement of an upwind tower impossible. In addition, purchase and erection of a meteorological tower can be expensive, particularly as the hub height of large turbines increases. Because of these concerns, wind farm owners and turbine manufacturers have expressed interest in the use of turbine nacelle-mounted anemometers for collection of wind speed data. The U.S. Department of Energy (DOE)-Electric Power Research Institute (EPRI) Wind Turbine Verification Program (TVP) has performed data collection and power performance tests at wind energy facilities located in the United States. The purpose of this paper is to evaluate the data gathered from the Big Spring, Texas; Algona, Iowa; and Springview, Nebraska, facilities to determine whether a meaningful relationship can be derived between meteorological-tower and nacelle-anemometer wind speed measurements for Vestas V47 and V66 turbines (Big Spring) and Enron Z-50 turbines (Algona and Springview).

Gas Turbine Emissions  

E-Print Network (OSTI)

Historically, preliminary design information regarding gas turbine emissions has been unreliable, particularly for facilities using steam injection and other forms of Best Available Control Technology (BACT). This was probably attributed to the lack of regulatory interest in the 'real world' test results coupled with the difficulties of gathering analogous bench test data for systems employing gas turbines with Heat Recovery Steam Generators (HRSG) and steam injection. It appears that the agencies are getting a better grasp of emissions, but there are still problem areas, particularly CO and unburned hydrocarbon emissions. The lag in data has resulted in the imposition of a CO reactor as BACT for the gas turbine. With the renewed concern about the environment, air permits will have a high profile with offsets being the next fix beyond BACT. 'The manner in which technology developers and electric utilities will share emissions reductions in the coming era of pollution allowance trading is becoming prominent on the agendas of strategic planners at technology vendors and the electric power industry....' (1) Therefore, it becomes increasingly important that the proponents of gas turbine-based facilities establish more reliable data on their proposed emissions. This paper addresses the gas turbine emissions experiences of eight cogeneration plants utilizing: 1) steam injection for both NOx control and power augmentation, 2) CO reactors, 3) selective catalytic reduction units. It also looks at possible regulatory actions.

Ceramic stationary gas turbine  

DOE Green Energy (OSTI)

The performance of current industrial gas turbines is limited by the temperature and strength capabilities of the metallic structural materials in the engine hot section. Because of their superior high-temperature strength and durability, ceramics can be used as structural materials for hot section components (blades, nozzles, combustor liners) in innovative designs at increased turbine firing temperatures. The benefits include the ability to increase the turbine inlet temperature (TIT) to about 1200{degrees}C ({approx}2200{degrees}F) or more with uncooled ceramics. It has been projected that fully optimized stationary gas turbines would have a {approx}20 percent gain in thermal efficiency and {approx}40 percent gain in output power in simple cycle compared to all metal-engines with air-cooled components. Annual fuel savings in cogeneration in the U.S. would be on the order of 0.2 Quad by 2010. Emissions reductions to under 10 ppmv NO{sub x} are also forecast. This paper describes the progress on a three-phase, 6-year program sponsored by the U.S. Department of Energy, Office of Industrial Technologies, to achieve significant performance improvements and emissions reductions in stationary gas turbines by replacing metallic hot section components with ceramic parts. Progress is being reported for the period September 1, 1994, through September 30, 1995.

A gas turbine power unit is disclosed in which the arrangement and configuration of parts is such as to save space and weight in order to provide a compact and self-contained assembly. An air-intake casing supports the upstream end of a gas generator, the down-stream end of which is integral with a power turbine. The stator casing of the turbine is connected to a cone thermally insulated and completely inserted into any exhaust casing having a vertical outlet, wherein the turbine exhaust is conveyed into the exhaust casing by an annular diffusing cone. The turbine casing is supported on four legs. In addition, the turbine rotor and thus the turbine shaft are overhangingly supported by an independent structure, the weight of which bears on the machine base outside the exhaust casing and away of the power turbine space.

Innovative Design Approaches for Large Wind Turbine Blades  

SciTech Connect

The primary goal of the WindPACT Blade System Design Study (BSDS) was investigation and evaluation of design and manufacturing issues for wind turbine blades in the one to ten megawatt size range. The initial project task was to assess the fundamental physical and manufacturing issues that govern and constrain large blades and entails three basic elements: (1) a parametric scaling study to assess blade structure using current technology, (2) an economic study of the cost to manufacture, transport, and install large blades, and (3) identification of promising innovative design approaches that show potential for overcoming fundamental physical and manufacturing constraints. This report discusses several innovative design approaches and their potential for blade cost reduction. During this effort we reviewed methods for optimizing the blade cross-section to improve structural and manufacturing characteristics. We also analyzed and compared a number of composite materials and evaluated their relative merits for use in large wind turbine blades in the range from 30 meters to 70 meters. The results have been summarized in dimensional and non-dimensional format to aid in interpretation. These results build upon earlier parametric and blade cost studies, which were used as a guide for the innovative design approaches explored here.

Wind turbine spoiler  

DOE Patents (OSTI)

An aerodynamic spoiler system for a vertical axis wind turbine includes spoilers on the blades initially stored near the rotor axis to minimize drag. A solenoid latch adjacent the central support tower releases the spoilers and centrifugal force causes the spoilers to move up the turbine blades away from the rotor axis, thereby producing a braking effect and actual slowing of the associated wind turbine, if desired. The spoiler system can also be used as an infinitely variable power control by regulated movement of the spoilers on the blades over the range between the undeployed and fully deployed positions. This is done by the use of a suitable powered reel and cable located at the rotor tower to move the spoilers.

Operating experience feedback report -- turbine-generator overspeed protection systems: Commercial power reactors. Volume 11  

SciTech Connect

This report presents the results of the US Nuclear Regulatory Commission`s Office for Analysis and Evaluation of Operational Data (AEOD) review of operating experience of main turbine-generator overspeed and overspeed protection systems. It includes an indepth examination of the turbine overspeed event which occurred on November 9, 1991, at the Salem Unit 2 Nuclear Power Plant. It also provides information concerning actions taken by other utilities and the turbine manufacturers as a result of the Salem overspeed event. AEOD`s study reviewed operating procedures and plant practices. It noted differences between turbine manufacturer designs and recommendations for operations, maintenance, and testing, and also identified significant variations in the manner that individual plants maintain and test their turbine overspeed protection systems. AEOD`s study provides insight into the shortcomings in the design, operation, maintenance, testing, and human factors associated with turbine overspeed protection systems. Operating experience indicates that the frequency of turbine overspeed events is higher than previously thought and that the bases for demonstrating compliance with NRC`s General Design Criterion (GDC) 4, Environmental and dynamic effects design bases, may be nonconservative with respect to the assumed frequency.

ADVANCED TURBINE SYSTEMS PROGRAM  

SciTech Connect

Natural gas combustion turbines are rapidly becoming the primary technology of choice for generating electricity. At least half of the new generating capacity added in the US over the next twenty years will be combustion turbine systems. The Department of Energy has cosponsored with Siemens Westinghouse, a program to maintain the technology lead in gas turbine systems. The very ambitious eight year program was designed to demonstrate a highly efficient and commercially acceptable power plant, with the ability to fire a wide range of fuels. The main goal of the Advanced Turbine Systems (ATS) Program was to develop ultra-high efficiency, environmentally superior and cost effective competitive gas turbine systems for base load application in utility, independent power producer and industrial markets. Performance targets were focused on natural gas as a fuel and included: System efficiency that exceeds 60% (lower heating value basis); Less than 10 ppmv NO{sub x} emissions without the use of post combustion controls; Busbar electricity that are less than 10% of state of the art systems; Reliability-Availability-Maintainability (RAM) equivalent to current systems; Water consumption minimized to levels consistent with cost and efficiency goals; and Commercial systems by the year 2000. In a parallel effort, the program was to focus on adapting the ATS engine to coal-derived or biomass fuels. In Phase 1 of the ATS Program, preliminary investigators on different gas turbine cycles demonstrated that net plant LHV based efficiency greater than 60% was achievable. In Phase 2 the more promising cycles were evaluated in greater detail and the closed-loop steam-cooled combined cycle was selected for development because it offered the best solution with least risk for achieving the ATS Program goals for plant efficiency, emissions, cost of electricity and RAM. Phase 2 also involved conceptual ATS engine and plant design and technology developments in aerodynamics, sealing, combustion, cooling, materials, coatings and casting development. The market potential for the ATS gas turbine in the 2000-2014 timeframe was assessed for combined cycle, simple cycle and integrated gasification combined cycle, for three engine sizes. The total ATS market potential was forecasted to exceed 93 GW. Phase 3 and Phase 3 Extension involved further technology development, component testing and W501ATS engine detail design. The technology development efforts consisted of ultra low NO{sub x} combustion, catalytic combustion, sealing, heat transfer, advanced coating systems, advanced alloys, single crystal casting development and determining the effect of steam on turbine alloys. Included in this phase was full-load testing of the W501G engine at the McIntosh No. 5 site in Lakeland, Florida.

TX-100 manufacturing final project report.  

DOE Green Energy (OSTI)

This report details the work completed under the TX-100 blade manufacturing portion of the Carbon-Hybrid Blade Developments: Standard and Twist-Coupled Prototype project. The TX-100 blade is a 9 meter prototype blade designed with bend-twist coupling to augment the mitigation of peak loads during normal turbine operation. This structural coupling was achieved by locating off axis carbon fiber in the outboard portion of the blade skins. The report will present the tooling selection, blade production, blade instrumentation, blade shipping and adapter plate design and fabrication. The baseline blade used for this project was the ERS-100 (Revision D) wind turbine blade. The molds used for the production of the TX-100 were originally built for the production of the CX-100 blade. The same high pressure and low pressure skin molds were used to manufacture the TX-100 skins. In order to compensate for the difference in skin thickness between the CX-100 and the TX-100, however, a new TX-100 shear web plug and mold were required. Both the blade assembly fixture and the root stud insertion fixture used for the CX-100 blades could be utilized for the TX-100 blades. A production run of seven TX-100 prototype blades was undertaken at TPI Composites during the month of October, 2004. Of those seven blades, four were instrumented with strain gauges before final assembly. After production at the TPI Composites facility in Rhode Island, the blades were shipped to various test sites: two blades to the National Wind Technology Center at the National Renewable Energy Laboratory in Boulder, Colorado, two blades to Sandia National Laboratory in Albuquerque, New Mexico and three blades to the United States Department of Agriculture turbine field test facility in Bushland, Texas. An adapter plate was designed to allow the TX-100 blades to be installed on existing Micon 65/13M turbines at the USDA site. The conclusion of this program is the kick-off of the TX-100 blade testing at the three testing facilities.

Final Report: Retrofit Aeration System (RAS) for Francis Turbine  

DOE Green Energy (OSTI)

Osage Plant and Bagnell Dam impounds the Osage River forming the Lake of the Ozarks in Missouri. Since it is nearly 100 feet deep, the lake stratifies during the summer months causing low DO water to be discharged into the Osage river below the dam. To supplement DO, the turbines are vented during the low DO season. AmerenUE is continually researching new methods of DO enhancement. New turbines, manufactured by American Hydro Corporation, were installed in Units 3 & 5 during the spring of 2002. Additional vent capacity and new nosecones were included in the new turbine design. The retrofit aeration system is an attempt to further enhance the DO in the tailrace by installation of additional venting capability on Unit 6 (not upgraded with new turbine) and refining design on special nosecones which will be mounted on both Unit 3 (upgraded turbine) and Unit 6. Baseline DO testing for Units 3 & 6 was conducted mid August, 2002. This data wascompared to further tests planned for the summer of 2003 and 2004 after installation of the retrofit aeration system.

Energy harvesting to power sensing hardware onboard wind turbine blade  

SciTech Connect

Wind turbines are becoming a larger source of renewable energy in the United States. However, most of the designs are geared toward the weather conditions seen in Europe. Also, in the United States, manufacturers have been increasing the length of the turbine blades, often made of composite materials, to maximize power output. As a result of the more severe loading conditions in the United States and the material level flaws in composite structures, blade failure has been a more common occurrence in the U.S. than in Europe. Therefore, it is imperative that a structural health monitoring system be incorporated into the design of the wind turbines in order to monitor flaws before they lead to a catastrophic failure. Due to the rotation of the turbine and issues related to lightning strikes, the best way to implement a structural health monitoring system would be to use a network of wireless sensor nodes. In order to provide power to these sensor nodes, piezoelectric, thermoelectric and photovoltaic energy harvesting techniques are examined on a cross section of a CX-100 wind turbine blade in order to determine the feasibility of powering individual nodes that would compose the sensor network.

U.S. Department of Energy Wind Turbine Development Projects  

DOE Green Energy (OSTI)

This paper provides an overview of wind-turbine development activities in the Unites States and relates those activities to market conditions and projections. Several factors are responsible for a surge in wind energy development in the United States, including a federal production tax credit, ''green power'' marketing, and improving cost and reliability. More development is likely, as approximately 363 GW of new capacity will be needed by 2020 to meet growing demand and replace retiring units. The U.S. Department of Energy (DOE) is helping two companies develop next-generation turbines intended to generate electricity for $0.025/kWh or less. We expect to achieve this objective through a combination of improved engineering methods and configuration advancements. This should ensure that wind power will compete effectively against advanced combined-cycle plants having projected generating costs of $0.031/kWh in 2005. To address the market for small and intermediate-size wind turbines, DOE is assisting five companies in their attempts to develop new turbines having low capital cost and high reliability. Additional information regarding U.S. wind energy programs is available on the internet site www.nrel.gov/wind/. E-mail addresses for the turbine manufacturers are found in the Acknowledgements.

UNIVERSITY TURBINE SYSTEMS RESEARCH PROGRAM SUMMARY AND DIRECTORY  

Science Conference Proceedings (OSTI)

The South Carolina Institute for Energy Studies (SCIES), administratively housed at Clemson University, has participated in the advancement of combustion turbine technology for over a decade. The University Turbine Systems Research Program, previously referred to as the Advanced Gas Turbine Systems Research (AGTSR) program, has been administered by SCIES for the U.S. DOE during the 1992-2003 timeframe. The structure of the program is based on a concept presented to the DOE by Clemson University. Under the supervision of the DOE National Energy Technology Laboratory (NETL), the UTSR consortium brings together the engineering departments at leading U.S. universities and U.S. combustion turbine developers to provide a solid base of knowledge for the future generations of land-based gas turbines. In the UTSR program, an Industrial Review Board (IRB) (Appendix C) of gas turbine companies and related organizations defines needed gas turbine research. SCIES prepares yearly requests for university proposals to address the research needs identified by the IRB organizations. IRB technical representatives evaluate the university proposals and review progress reports from the awarded university projects.

Turbine blade tip gap reduction system  

DOE Patents (OSTI)

A turbine blade sealing system for reducing a gap between a tip of a turbine blade and a stationary shroud of a turbine engine. The sealing system includes a plurality of flexible seal strips extending from a pressure side of a turbine blade generally orthogonal to the turbine blade. During operation of the turbine engine, the flexible seal strips flex radially outward extending towards the stationary shroud of the turbine engine, thereby reducing the leakage of air past the turbine blades and increasing the efficiency of the turbine engine.

SMART POWER TURBINE  

SciTech Connect

Gas turbines are the choice technology for high-performance power generation and are employed in both simple and combined cycle configurations around the world. The Smart Power Turbine (SPT) program has developed new technologies that are needed to further extend the performance and economic attractiveness of gas turbines for power generation. Today's power generation gas turbines control firing temperatures indirectly, by measuring the exhaust gas temperature and then mathematically calculating the peak combustor temperatures. But temperatures in the turbine hot gas path vary a great deal, making it difficult to control firing temperatures precisely enough to achieve optimal performance. Similarly, there is no current way to assess deterioration of turbine hot-gas-path components without shutting down the turbine. Consequently, maintenance and component replacements are often scheduled according to conservative design practices based on historical fleet-averaged data. Since fuel heating values vary with the prevalent natural gas fuel, the inability to measure heating value directly, with sufficient accuracy and timeliness, can lead to maintenance and operational decisions that are less than optimal. GE Global Research Center, under this Smart Power Turbine program, has developed a suite of novel sensors that would measure combustor flame temperature, online fuel lower heating value (LHV), and hot-gas-path component life directly. The feasibility of using the ratio of the integrated intensities of portions of the OH emission band to determine the specific average temperature of a premixed methane or natural-gas-fueled combustion flame was demonstrated. The temperature determined is the temperature of the plasma included in the field of view of the sensor. Two sensor types were investigated: the first used a low-resolution fiber optic spectrometer; the second was a SiC dual photodiode chip. Both methods worked. Sensitivity to flame temperature changes was remarkably high, that is a 1-2.5% change in ratio for an 11.1 C (20 F) change in temperature at flame temperatures between 1482.2 C (2700 F) and 1760 C (3200 F). Sensor ratio calibration was performed using flame temperatures determined by calculations using the amount of unburned oxygen in the exhaust and by the fuel/air ratio of the combustible gas mixture. The agreement between the results of these two methods was excellent. The sensor methods characterized are simple and viable. Experiments are underway to validate the GE Flame Temperature Sensor as a practical tool for use with multiburner gas turbine combustors. The lower heating value (LHV) Fuel Quality Sensor consists of a catalytic film deposited on the surface of a microhotplate. This micromachined design has low heat capacity and thermal conductivity, making it ideal for heating catalysts placed on its surface. Several methods of catalyst deposition were investigated, including micropen deposition and other proprietary methods, which permit precise and repeatable placement of the materials. The use of catalysts on the LHV sensor expands the limits of flammability (LoF) of combustion fuels as compared with conventional flames; an unoptimized LoF of 1-32% for natural gas (NG) in air was demonstrated with the microcombustor, whereas conventionally 4 to 16% is observed. The primary goal of this work was to measure the LHV of NG fuels. The secondary goal was to determine the relative quantities of the various components of NG mixes. This determination was made successfully by using an array of different catalysts operating at different temperatures. The combustion parameters for methane were shown to be dependent on whether Pt or Pd catalysts were used. In this project, significant effort was expended on making the LHV platform more robust by the addition of high-temperature stable materials, such as tantalum, and the use of passivation overcoats to protect the resistive heater/sensor materials from degradation in the combustion environment. Modeling and simulation were used to predict improved sensor designs.

Advanced Turbine System (ATS) program conceptual design and product development. Quarterly report, March 1, 1994--May 31, 1994  

DOE Green Energy (OSTI)

GE has achieved a leadership position in the worldwide gas turbine industry in both industrial/utility markets and in aircraft engines. This design and manufacturing base plus their close contact with the users provides the technology for creation of the next generation advanced power generation systems for both the industrial and utility industries. GE has been active in the definition of advanced turbine systems for several years. These systems will leverage the technology from the latest developments in the entire GE gas turbine product line. These products will be USA based in engineering and manufacturing and are marketed through the GE Industrial and Power Systems. Achieving the advanced turbine system goals of 60% efficiency, 8 ppmvd NO{sub x} and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NO{sub x} emission. Improved coating and materials technologies along with creative combustor design can result in solutions to achieve the ultimate goal. GE`s view of the market, in conjunction with the industrial and utility objectives requires the development of Advanced Gas Turbine Systems which encompasses two potential products: a new aeroderivative combined cycle system for the industrial market and a combined cycle system for the utility sector that is based on an advanced frame machine.

Torque ripple in a Darrieus, vertical axis wind turbine  

DOE Green Energy (OSTI)

Interaction between a steady wind and a rotating, Darrieus, vertical axis wind turbine produces time periodic aerodynamic loads which cause time dependent torque variations, referred to as torque ripple, to occur in the mechanical link between the turbine and the electrical generator. There is concern for the effect of torque ripple upon fatigue life of drive train components and upon power quality. An analytical solution characterizing the phenomenon of torque ripple has been obtained which is based upon a Fourier expansion of the time dependent features of the problem. Numerical results for torque ripple, some experimental data, determination of acceptable levels and methods of controlling it, are presented and discussed.

NREL Collaborates to Improve Wind Turbine Technology (Fact Sheet)  

DOE Green Energy (OSTI)

NREL's Gearbox Reliability Collaborative leads to wind turbine gearbox reliability, lowering the cost of energy. Unintended gearbox failures have a significant impact on the cost of wind farm operations. In 2007, the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC), which follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers, and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. NREL and other GRC partners have been able to identify shortcomings in the design, testing, and operation of wind turbines that contribute to reduced gearbox reliability. In contrast to private investigations of these problems, GRC findings are quickly shared among GRC participants, including many wind turbine manufacturers and equipment suppliers. Ultimately, the findings are made public for use throughout the wind industry. This knowledge will result in increased gearbox reliability and an overall reduction in the cost of wind energy. Project essentials include the development of two redesigned and heavily instrumented representative gearbox designs. Field and dynamometer tests are conducted on the gearboxes to build an understanding of how selected loads and events translate into bearing and gear response. The GRC evaluates and validates current wind turbine, gearbox, gear and bearing analytical tools/models, develops new tools/models, and recommends improvements to design and certification standards, as required. In addition, the GRC is investigating condition monitoring methods to improve turbine reliability. Gearbox deficiencies are the result of many factors, and the GRC team recommends efficient and cost-effective improvements in order to expand the industry knowledge base and facilitate immediate improvements in the gearbox life cycle.

Advanced Hydrogen Turbine Development  

DOE Green Energy (OSTI)

Siemens has developed a roadmap to achieve the DOE goals for efficiency, cost reduction, and emissions through innovative approaches and novel technologies which build upon worldwide IGCC operational experience, platform technology, and extensive experience in G-class operating conditions. In Phase 1, the technologies and concepts necessary to achieve the program goals were identified for the gas turbine components and supporting technology areas and testing plans were developed to mitigate identified risks. Multiple studies were conducted to evaluate the impact in plant performance of different gas turbine and plant technologies. 2015 gas turbine technologies showed a significant improvement in IGCC plant efficiency, however, a severe performance penalty was calculated for high carbon capture cases. Thermodynamic calculations showed that the DOE 2010 and 2015 efficiency targets can be met with a two step approach. A risk management process was instituted in Phase 1 to identify risk and develop mitigation plans. For the risks identified, testing and development programs are in place and the risks will be revisited periodically to determine if changes to the plan are necessary. A compressor performance prediction has shown that the design of the compressor for the engine can be achieved with additional stages added to the rear of the compressor. Tip clearance effects were studied as well as a range of flow and pressure ratios to evaluate the impacts to both performance and stability. Considerable data was obtained on the four candidate combustion systems: diffusion, catalytic, premix, and distributed combustion. Based on the results of Phase 1, the premixed combustion system and the distributed combustion system were chosen as having the most potential and will be the focus of Phase 2 of the program. Significant progress was also made in obtaining combustion kinetics data for high hydrogen fuels. The Phase 1 turbine studies indicate initial feasibility of the advanced hydrogen turbine that meets the aggressive targets set forth for the advanced hydrogen turbine, including increased rotor inlet temperature (RIT), lower total cooling and leakage air (TCLA) flow, higher pressure ratio, and higher mass flow through the turbine compared to the baseline. Maintaining efficiency with high mass flow Syngas combustion is achieved using a large high AN2 blade 4, which has been identified as a significant advancement beyond the current state-of-the-art. Preliminary results showed feasibility of a rotor system capable of increased power output and operating conditions above the baseline. In addition, several concepts were developed for casing components to address higher operating conditions. Rare earth modified bond coat for the purpose of reducing oxidation and TBC spallation demonstrated an increase in TBC spallation life of almost 40%. The results from Phase 1 identified two TBC compositions which satisfy the thermal conductivity requirements and have demonstrated phase stability up to temperatures of 1850 C. The potential to join alloys using a bonding process has been demonstrated and initial HVOF spray deposition trials were promising. The qualitative ranking of alloys and coatings in environmental conditions was also performed using isothermal tests where significant variations in alloy degradation were observed as a function of gas composition. Initial basic system configuration schematics and working system descriptions have been produced to define key boundary data and support estimation of costs. Review of existing materials in use for hydrogen transportation show benefits or tradeoffs for materials that could be used in this type of applications. Hydrogen safety will become a larger risk than when using natural gas fuel as the work done to date in other areas has shown direct implications for this type of use. Studies were conducted which showed reduced CO{sub 2} and NOx emissions with increased plant efficiency. An approach to maximize plant output is needed in order to address the DOE turbine goal for 20-30% reduction o

Gas turbines for the future  

SciTech Connect

Utility gas turbine technology has been advancing fairly rapidly, one reason being that it shares in the benefits of the research and development for aviation gas turbines. In general, turbine progress is characterized by large, incremental advances in performance. At intervals of approx. 15 yr, new-generation turbines are introduced, refined, and eventually installed in relatively large numbers. A new generation of turbines is being readied for the market that will have power ratings into the 130- to 150-MW range (simple cycle), significantly higher than the 70 to 100 MW now in service. When the new turbines are installed in combined-cycle plants, the efficiency levels are expected to rise from the present value of approx. 42% higher heating value to approx. 46%.

The Manufacturing Laboratory at NREL's Energy Systems Integration Facility (ESIF) focuses on developing methods and technologies that will assist manufacturers of hydrogen and fuel cell technologies, as well as other renewable energy technologies, to scale up their manufacturing capabilities to volumes that meet DOE and industry targets. Specifically, the manufacturing activity is currently focused on developing and validating quality control techniques to assist manufacturers of low temperature and high temperature fuel cells in the transition from low to high volume production methods for cells and stacks. Capabilities include initial proof-of-concept studies through prototype system development and in-line validation. Existing diagnostic capabilities address a wide range of materials, including polymer films, carbon and catalyst coatings, carbon fiber papers and wovens, and multi-layer assemblies of these materials, as well as ceramic-based materials in pre- or post-fired forms. Work leading to the development of non-contact, non-destructive techniques to measure critical dimensional and functional properties of fuel cell and other materials, and validation of those techniques on the continuous processing line. This work will be supported by materials provided by our partners. Looking forward, the equipment in the laboratory is set up to be modified and extended to provide processing capabilities such as coating, casting, and deposition of functional layers, as well as associated processes such as drying or curing. In addition, continuous processes are used for components of organic and thin film photovoltaics (PV) as well as battery technologies, so synergies with these important areas will be explored.

Advanced turbine systems sensors and controls needs assessment study. Final report  

DOE Green Energy (OSTI)

The Instrumentation and Controls Division of the Oak Ridge National Laboratory performed an assessment of the sensors and controls needs for land-based advanced gas turbines being designed as a part of the Department of Energy`s (DOE`s) Advanced Turbine Systems (ATS) Program for both utility and industrial applications. The assessment included visits to five turbine manufacturers. During these visits, in-depth discussions were held with design and manufacturing staff to obtain their views regarding the need for new sensors and controls for their advanced turbine designs. The Unsteady Combustion Facilities at the Morgantown Energy Technology Center was visited to assess the need for new sensors for gas turbine combustion research. Finally, a workshop was conducted at the South Carolina Energy Research and Development Center which provided a forum for industry, laboratory, and university engineers to discuss and prioritize sensor and control needs. The assessment identified more than 50 different measurement, control, and monitoring needs for advanced turbines that cannot currently be met from commercial sources. While all the identified needs are important, some are absolutely critical to the success of the ATS Program.

Tornado type wind turbines  

DOE Patents (OSTI)

A tornado type wind turbine has a vertically disposed wind collecting tower with spaced apart inner and outer walls and a central bore. The upper end of the tower is open while the lower end of the structure is in communication with a wind intake chamber. An opening in the wind chamber is positioned over a turbine which is in driving communication with an electrical generator. An opening between the inner and outer walls at the lower end of the tower permits radially flowing air to enter the space between the inner and outer walls while a vertically disposed opening in the wind collecting tower permits tangentially flowing air to enter the central bore. A porous portion of the inner wall permits the radially flowing air to interact with the tangentially flowing air so as to create an intensified vortex flow which exits out of the top opening of the tower so as to create a low pressure core and thus draw air through the opening of the wind intake chamber so as to drive the turbine.

Development of a more fish tolerant turbine runner advanced hydropower turbine project. Final report  

DOE Green Energy (OSTI)

The Hidrostal pump is a single bladed combined screw/centrifugal pump which has been proven to transport fish with minimal injury. The focus of the ARL/NREC research project was to develop a new runner geometry which is effective in downstream fish passage and hydroelectric power generation. A flow of 1,000 cfs and a head in the range of 75 ft to 100 ft were selected for conceptual design of the new runner. Criteria relative to hydraulic characteristics which are favorable for fish passage were prepared based on a reassessment of the available information. Important criteria used to develop the new runner design included low pressure change rates, minimum absolute pressures, and minimum shear. Other criteria which are reflected in the runner design are a minimum number of blades (only two), minimum total length of leading edges, and large flow passages. Flow characteristics of the new runner were analyzed using two- dimensional and three-dimensional Computational Fluid Dynamic (CFD) models. The basic runner geometry was initially selected using the two-dimensional model. The three-dimensional model was used to investigate the flow characteristics in detail through the entire runner and to refine the design by eliminating potential problem areas at the leading and trailing edges. Results of the analyses indicated that the runner has characteristics which should provide safe fish passage with an overall power efficiency of approximately 90%. The size of the new runner, which is larger than conventional turbine runners with the same design flow and head, will provide engineering, fabrication, and installation.challenges related to the turbine components and the civil works. A small reduction in the overall efficiency would reduce the size of the runner considerably, would simplify the turbine manufacturing operations, and would allow installation of the new turbine at more hydroelectric sites.

Reference Inflow Characterization for River Resource Reference Model (RM2)  

DOE Green Energy (OSTI)

Sandia National Laboratory (SNL) is leading an effort to develop reference models for marine and hydrokinetic technologies and wave and current energy resources. This effort will allow the refinement of technology design tools, accurate estimates of a baseline levelized cost of energy (LCoE), and the identification of the main cost drivers that need to be addressed to achieve a competitive LCoE. As part of this effort, Oak Ridge National Laboratory was charged with examining and reporting reference river inflow characteristics for reference model 2 (RM2). Published turbulent flow data from large rivers, a water supply canal and laboratory flumes, are reviewed to determine the range of velocities, turbulence intensities and turbulent stresses acting on hydrokinetic technologies, and also to evaluate the validity of classical models that describe the depth variation of the time-mean velocity and turbulent normal Reynolds stresses. The classical models are found to generally perform well in describing river inflow characteristics. A potential challenge in river inflow characterization, however, is the high variability of depth and flow over the design life of a hydrokinetic device. This variation can have significant effects on the inflow mean velocity and turbulence intensity experienced by stationary and bottom mounted hydrokinetic energy conversion devices, which requires further investigation, but are expected to have minimal effects on surface mounted devices like the vertical axis turbine device designed for RM2. A simple methodology for obtaining an approximate inflow characterization for surface deployed devices is developed using the relation umax=(7/6)V where V is the bulk velocity and umax is assumed to be the near-surface velocity. The application of this expression is recommended for deriving the local inflow velocity acting on the energy extraction planes of the RM2 vertical axis rotors, where V=Q/A can be calculated given a USGS gage flow time-series and stage vs. cross-section area rating relationship.

Alstom 3-MW Wind Turbine Installed at NWTC (Fact Sheet)  

DOE Green Energy (OSTI)

The 3-MW Alstom wind turbine was installed at NREL's NWTC in October 2010. Test data will be used to validate advanced turbine design and analysis tools. NREL signed a Cooperative Research and Development Agreement with Alstom in 2010 to conduct certification testing on the company's 3-MW ECO 100 wind turbine and to validate models of Alstom's unique drivetrain concept. The turbine was installed at NREL's National Wind Technology Center (NWTC) in October 2010 and engineers began certification testing in 2011. Tests to be conducted by NREL include a power quality test to finalize the International Electrotechnical Commission (IEC) requirements for type certification of the 60-Hz unit. The successful outcome of this test will enable Alstom to begin commercial production of ECO 100 in the United States. NREL also will obtain additional measurements of power performance, acoustic noise, and system frequency to complement the 50 Hz results previously completed in Europe. After NREL completes the certification testing on the ECO 100, it will conduct long-term testing to validate gearbox performance to gain a better understanding of the machine's unique ALSTOM PURE TORQUE{trademark} drivetrain concept. In conventional wind turbines, the rotor is supported by the shaft-bearing gearbox assembly. Rotor loads are partially transmitted to the gearbox and may reduce gearbox reliability. In the ALSTOM PURE TORQUE concept, the rotor is supported by a cast frame running through the hub, which transfers bending loads directly to the tower. Torque is transmitted to the shaft through an elastic coupling at the front of the hub. According to Alstom, this system will increase wind turbine reliability and reduce operation and maintenance costs by isolating the gearbox from rotor loads. Gearbox reliability has challenged the wind energy industry for more than two decades. Gearbox failures require expensive and time-consuming replacement, significantly increasing the cost of wind plant operation while reducing the plant's power output and revenue. To solve gearbox reliability issues, NREL launched a Gearbox Reliability Collaborative (GRC) in 2006 and brought together the world's leading turbine manufacturers, consultants, and experts from more than 30 companies and organizations. GRC's goal was to validate the typical design process-from wind turbine system loads to bearing ratings-through a comprehensive dynamometer and field-test program. Design analyses will form a basis for improving reliability of future designs and retrofit packages. Through its study of Alstom's Eco 100 gearbox, NREL can compare its GRC model gearbox with Alstom's and add the results to the GRC database, which is helping to advance more reliable wind turbine technology.

Small gas-turbine-engine technology  

SciTech Connect

Performance of small gas turbine engines in the 250 to 1000 hp size range is significantly lower than that of large engines. Engines of this size are typically used in rotorcraft, commutercraft, general aviation, and cruise missile applications. Principal reasons for lower efficiencies of smaller engines are well known: Component efficiencies are lower by as much as 8 to 10 percentage points because of size effects. Small engines are designed for lower cycle pressures and temperatures because of smaller blading and cooling limitations. The highly developed analytical and manufacturing techniques evolved for large engines are not directly transferrable to small engines. Thus, it has been recognized that a focused effort addressing technologies for small engines was needed and could significantly impact their performance. Recently, in-house and contract studies were undertaken to identify advanced engine cycle and component requirements for substantial performance improvement of small gas turbines for projected year 2000 applications. This paper presents results of both in-house research and contract studies, conducted with Allison, AVCO Lycoming, Garrett, Teledyne CAE, and Williams International Rotorcraft results are emphasized. Projected fuel savings of 22-42% could be attained. Accompanying direct operating cost reductions of 11-17%, depending on fuel cost, were also estimated. High payoff technologies are identified for all engine applications, and recent results of experimental research to evolve the high payoff technologies are described.

A Summary of the Fatigue Properties of Wind Turbine Materials  

DOE Green Energy (OSTI)

Modern wind turbines are fatigue critical machines that are typically used to produce electrical power from the wind. The materials used to construct these machines are subjected to a unique loading spectrum that contains several orders of magnitude more cycles than other fatigue critical structures, e.g., an airplane. To facilitate fatigue designs, a large database of material properties has been generated over the past several years that is specialized to materials typically used in wind turbines. In this paper, I review these fatigue data. Major sections are devoted to the properties developed for wood, metals (primarily aluminum) and fiberglass. Special emphasis is placed on the fiberglass discussion because this material is current the material of choice for wind turbine blades. The paper focuses on the data developed in the U.S., but cites European references that provide important insights.
