Transforming the U.S. Energy Infrastructure  

SciTech Connect

The U.S. energy infrastructure is among the most reliable, accessible and economic in the world. On the other hand, the U.S. energy infrastructure is excessively reliant on foreign sources of energy, experiences high volatility in energy prices, does not practice good stewardship of finite indigenous energy resources and emits significant quantities of greenhouse gases (GHG). This report presents a Technology Based Strategy to achieve a full transformation of the U.S. energy infrastructure that corrects these negative factors while retaining the positives.

Reliability centered maintenance of power transformers and circuit breakers  

SciTech Connect

At the Bonneville Power Administration (BPA), we have historically maintained high voltage equipment. Including transformers and power circuit breakers, on a time driven basis. While this has served our needs in the past, newer methods are needed to effectively maintain the power system in future years. Today aging equipment, maintenance backlogs, and budget constraints are a reality. BPA has initiated a research and development project to examine reliability centered maintenance (RCM) as an alternative to time based maintenance on high voltage equipment. Under RCM, the performance of each place of equipment is to be monitored by observing many operating parameters. For example, with circuit breakers we will observe (measure) the trip time, accumulated contact wear using I{sup 2}T, timing of the mechanism, plus several other parameters. Equipment performing below a predetermined level, or equipment having accumulated a large amount of ``usage`` will receive maintenance. The maintenance will restore full performance and preserve an acceptable service life for that piece of equipment. To develop and evaluate RCM concepts, BPA is installing a prototype system at our Alvey Substation on 4 transformers and 25 breakers.

Inducing Transformational Energy Technological Change  

Science Conference Proceedings (OSTI)

Reducing risks of severe climate change in the latter part of the 20th Century is likely to require not only incremental improvements in known energy technologies, but the discovery of transformational new energy technologies. This paper reviews current knowledge about both demand and supply aspects of the challenge of accelerating transformational change, considering both economic and policy incentives, including targeted government funding of research and development, and several other schools of thought about drivers of scientific discovery and innovation.

Energy Efficiency and Reliability in Wireless Biomedical Implant Systems  

E-Print Network (OSTI)

The use of wireless implant technology requires correct delivery of the vital physiological signs of the patient along with the energy management in power-constrained devices. Toward these goals, we present an augmentation protocol for the physical layer of the Medical Implant Communications Service (MICS) with focus on the energy efficiency of deployed devices over the MICS frequency band. The present protocol uses the rateless code with the Frequency Shift Keying (FSK) modulation scheme to overcome the reliability and power cost concerns in tiny implantable sensors due to the considerable attenuation of propagated signals across the human body. In addition, the protocol allows a fast start-up time for the transceiver circuitry. The main advantage of using rateless codes is to provide an inherent adaptive duty-cycling for power management, due to the flexibility of the rateless code rate. Analytical results demonstrate that an 80% energy saving is achievable with the proposed protocol when compared to the IE...

Speaker(s): Norma Anglani Date: April 10, 2001 - 12:00pm Location: Bldg. 90 Seminar Host/Point of Contact: Kristina LaCommare The energy saving assessment for each chosen transformer is a very important issue in the rule-making process, not only because of the obvious environmental consequences but also considering the economic impact of the standards. The life cycle cost equation, which is a keystone feature, is also affected by the correct definition of the savings achieved by improving the efficiency of each class of transformers. Setting up efficiency standards by looking at what is offered in the current distribution transformers market doesn't necessarily entail an improvement

Emergency Diesel Generator reliability at Department of Energy (DOE) facilities  

Science Conference Proceedings (OSTI)

This report is the culmination of the first phase of a comprehensive effort by the Department of Energy (DOE) Defense Programs (DP) Office of Self-Assessment and Emergency Management (DP-9) to assess the reliability and availability of emergency power supplies (i.e., standby or backup supplies providing electric power to systems or equipment that perform functions important to safety) at DOE management concerns over the recent number of reported failures of emergency and back-up supplies to provide power when required. Augmented Evaluation Team (AET) on-site reviews were conducted during the week of September 30, 1991 at Rocky Flats (RF), and the week of October 7, 1991 at the Richland (RL) and Savannah River (SR) sites to investigate the failures. The AET reviews focused on Emergency Diesel Generator (EDG) failures because they were identified as the dominant contributor to power supply failures (46 of the 77 failures involved EDGs, as opposed to other sources such as batteries, motor-generator sets, etc.). The RF, RL, and SR sites were chosen because they were among the leaders in numbers of EDG failures. The objectives of the AET investigations were to collect, analyze, and document factual information concerning the causes, conditions, and circumstances surrounding EDG failures, to conduct a preliminary assessment of the safety significance of the failures and the site specific and generic safety implications for DOE facilities, and to identify appropriate follow-on actions necessary to complete the overall assessment of the adequacy of emergency and back-up power sources. This report presents the AET findings concerning the reliability of EDGs at the RF, RL, and SR sites, and the safety significance of EDG failures.

Reliable Protein Folding on Complex Energy Landscapes: The Free Energy Reaction Path  

E-Print Network (OSTI)

ABSTRACT A theoretical framework is developed to study the dynamics of protein folding. The key insight is that the search for the native protein conformation is influenced by the rate r at which external parameters, such as temperature, chemical denaturant, or pH, are adjusted to induce folding. A theory based on this insight predicts that 1), proteins with complex energy landscapes can fold reliably to their native state; 2), reliable folding can occur as an equilibrium or out-of-equilibrium process; and 3), reliable folding only occurs when the rate r is below a limiting value, which can be calculated from measurements of the free energy. We test these predictions against numerical simulations of model proteins with a single energy scale.

Magnetic energy harvesting and concentration at distance by transformation optics  

E-Print Network (OSTI)

Magnetic energy is one the main agents powering our society: generating energy in power plants, keeping information in magnetic memories, moving our devices with motors. All of these applications require a certain spatial distribution of magnetic energy, for example concentrating it in a transformer core or in a magnetic sensor. We introduce in this work a way to collect magnetic energy and distribute it in space with unprecedented efficiency and flexibility, allowing very large concentration of magnetic energy in a free space region, an enhanced magnetic coupling between two magnetic sources, and the transfer of magnetic energy from a source to a given distant point separated by empty space. All these features are achieved with a single device, a magnetic shell designed by transformation optics.

Reliability-aware dynamic energy management in dependable embedded real-time systems  

E-Print Network (OSTI)

Recent studies show that, voltage scaling, which is an efficient energy management technique, has a direct and negative effect on system reliability because of the increased rate of transient faults (e.g., those induced by cosmic particles). In this work, we propose energy management schemes that explicitly take system reliability into consideration. The proposed reliability-aware energy management schemes dynamically schedule recoveries for tasks to be scaled down to recuperate the reliability loss due to energy management. Based on the amount of available slack, the application size and the fault rate changes, we analyze when it is profitable to reclaim the slack for energy savings without sacrificing system reliability. Checkpoint technique is further explored to efficiently use the slack. Analytical and simulation results show that, the proposed schemes can achieve comparable energy savings as ordinary energy management schemes while preserving system reliability. The ordinary energy management schemes that ignore the effects of voltage scaling on fault rate changes could lead to drastically decreased system reliability.

Energy Management for Real-Time Embedded Systems with Reliability Requirements  

E-Print Network (OSTI)

With the continued scaling of CMOS technologies and reduced design margins, the reliability concerns induced by transient faults have become prominent. Moreover, the popular energy management technique dynamic voltage and frequency scaling (DVFS) has been shown to have direct and negative effects on reliability. In this work, for a set of real-time tasks, we focus on the slack allocation problem to minimize their energy consumption while preserving the overall system reliability. Building on our previous findings for a single real-time application where a recovery task was used to preserve reliability, we identify the problem of reliabilityaware energy management for multiple tasks as NP-hard and propose two polynomial-time heuristic schemes. We also investigate the effects of on-chip/off-chip workload decomposition on energy management, by considering a generalized power model. Simulation results show that ordinary energy management schemes could lead to drastically decreased system reliability, while the proposed reliability-aware heuristic schemes are able to preserve the system reliability and obtain significant energy savings at the same time.

Market Transformation Efforts for Residential Energy Efficient Windows: An  

NLE Websites -- All DOE Office Websites (Extended Search)

Market Transformation Efforts for Residential Energy Efficient Windows: An Market Transformation Efforts for Residential Energy Efficient Windows: An Update of National Activities Title Market Transformation Efforts for Residential Energy Efficient Windows: An Update of National Activities Publication Type Report LBNL Report Number LBNL-46620 Year of Publication 2000 Authors Ward, Alecia, Margaret Suozzo, and Joseph H. Eto Date Published 01/2000 Publisher LBNL Abstract With the burst of recent initiatives to accelerate adoption of energy-efficient fenestration technologies in the marketplace, an update on window market transformation efforts is needed. Because of the impact of glazing on total home energy performance, the residential window market has received increasing attention over the past two years. National programs such as the ENERGY STAR Windows program, the Efficient Windows Collaborative, and regional initiatives such as the California Windows Initiative and the Northwest Collaborative have begun to move markets toward higher-efficiency windows. The results have included increasing sales of efficient products, stocking of more efficient/ENERGY STAR qualifying products, and price reductions of high-efficiency product, all of which secure dramatic energy savings at a national level. This paper takes stock of publicly supported national and regional transformation efforts for residential windows underway in the U.S. In particular, it documents ways in which National Fenestration Rating Council certification, Efficient Windows Collaborative education, and ENERGY STAR marketing, are working together to change window markets across the United States. Although it is too early to quantify the national-level impacts changes of these efforts, the authors offer a preliminary qualitative evaluation of efficient window promotion efforts to gain insight into the broader impacts that these and other future activities will achieve. Finally, the paper summarizes how other federally-funded building industry initiatives that emphasize "whole house" performance can complement these window technology-specific and component-specific initiatives. Demonstration houses from the Building America, ENERGY STAR Homes, and PATH projects all contribute to the success of windows-specific initiatives.

Slice Energy in Higher Order Gravity Theories and Conformal Transformations  

E-Print Network (OSTI)

We study the generic transport of slice energy between the scalar field generated by the conformal transformation of higher-order gravity theories and the matter component. We give precise relations for this exchange in the cases of dust and perfect fluids. We show that, unless we are in a stationary spacetime where slice energy is always conserved, in non-stationary situations contributions to the total slice energy depend on whether or not test matter follows geodesics in both frame representations of the dynamics, that is on whether or not the two conformally related frames are physically indistinguishable.

The Energy Transformation Limit Theorem for Gas Flow Systems  

E-Print Network (OSTI)

The limit energy theorem which determines the possibility of transformation the energy flow in power systems in the absence of technical work is investigated and proved for such systems as gas lasers and plasmatrons, chemical gas reactors, vortex tubes, gas-acoustic and other systems, as well as a system of close stars. In the case of the same name ideal gas in the system the maximum ratio of energy conversion effectiveness is linked to the Carnot theorem, which in its turn is connected with the Nernst theorem. However, numerical analyses show that the class of flow energy systems is non-carnot one. The ratio of energy conversion effectiveness depends on the properties of the working medium; a conventional cycle in open-circuit is essentially irreversible. The proved theorem gives a more strongly worded II law of thermodynamics for the selected class of flow energy systems. Implications for astrophysical thermodynamic systems and the theory of a strong shock wave are discussed.

TRANSFORMATION  

SciTech Connect

Transformation, which alters the genetic makeup of an individual, is a concept that intrigues the human imagination. In Streptococcus pneumoniae such transformation was first demonstrated. Perhaps our fascination with genetics derived from our ancestors observing their own progeny, with its retention and assortment of parental traits, but such interest must have been accelerated after the dawn of agriculture. It was in pea plants that Gregor Mendel in the late 1800s examined inherited traits and found them to be determined by physical elements, or genes, passed from parents to progeny. In our day, the material basis of these genetic determinants was revealed to be DNA by the lowly bacteria, in particular, the pneumococcus. For this species, transformation by free DNA is a sexual process that enables cells to sport new combinations of genes and traits. Genetic transformation of the type found in S. pneumoniae occurs naturally in many species of bacteria (70), but, initially only a few other transformable species were found, namely, Haemophilus influenzae, Neisseria meningitides, Neisseria gonorrheae, and Bacillus subtilis (96). Natural transformation, which requires a set of genes evolved for the purpose, contrasts with artificial transformation, which is accomplished by shocking cells either electrically, as in electroporation, or by ionic and temperature shifts. Although such artificial treatments can introduce very small amounts of DNA into virtually any type of cell, the amounts introduced by natural transformation are a million-fold greater, and S. pneumoniae can take up as much as 10% of its cellular DNA content (40).

A FRAMEWORK FOR ASSESSING THE RELIABILITY OF WIND ENERGY CONVERSION SYSTEMS  

E-Print Network (OSTI)

During the last decade, wind power generation has seen rapid development. According to the U.S. Department of Energy, achieving 20 % wind power penetration in the U.S. by 2030 will require: (i) enhancement of the transmission infrastructure, (ii) improvement of reliability and operability of wind systems and (iii) increased U.S. manufacturing capacity of wind generation equipment. This research will concentrate on improvement of reliability and operability of wind energy conversion systems (WECSs). The increased penetration of wind energy into the grid imposes new operating conditions on power systems. This change requires development of an adequate reliability framework. This thesis proposes a framework for assessing WECS reliability in the face of external disturbances, e.g., grid faults and internal component faults. The framework is illustrated using a detailed model of type C WECS- doubly fed induction generator with corresponding deterministic and random variables in a simplified grid model.

Reliability estimation for multiunit nuclear and fossil-fired industrial energy systems  

SciTech Connect

The purpose of this paper is twofold: to report industrial experience with process energy system reliability, and to assess the reliability of multiunit nuclear and fossil-fired energy systems in an industrial setting. Reliability here refers to the percentage of clock time that sufficient amounts of steam energy were available to permit desired production quotas to be met at a particular plant. A nationwide survey was conducted to obtain data relative to energy system reliabilities during 1973--74, and these data for 29 plants from chemicals and allied products (S.I.C. 28), petroleum refining and related industries (S.I.C. 29) and primary metals industries (S.I.C. 33) are reported here. A simulation model in which various operating characteristics of the energy systems were taken into account was developed to obtain estimates of reliabilities of proposed multiunit nuclear and fossil-fired systems. Based on several example problems evaluated with the simulation model, study results indicated that multiple nuclear units or a combination of nuclear and fossil-fired units could provide adequate reliability to meet large-scale industrial requirements for continuity of service.

Integration of renewable energy sources: reliability-constrained power system planning and operations using computational intelligence  

E-Print Network (OSTI)

Renewable sources of energy such as wind turbine generators and solar panels have attracted much attention because they are environmentally friendly, do not consume fossil fuels, and can enhance a nation’s energy security. As a result, recently more significant amounts of renewable energy are being integrated into conventional power grids. The research reported in this dissertation primarily investigates the reliability-constrained planning and operations of electric power systems including renewable sources of energy by accounting for uncertainty. The major sources of uncertainty in these systems include equipment failures and stochastic variations in time-dependent power sources. Different energy sources have different characteristics in terms of cost, power dispatchability, and environmental impact. For instance, the intermittency of some renewable energy sources may compromise the system reliability when they are integrated into the traditional power grids. Thus, multiple issues should be considered in grid interconnection, including system cost, reliability, and pollutant emissions. Furthermore, due to the high complexity and high nonlinearity of such non-traditional power systems with multiple energy sources, computational intelligence based optimization methods are used to resolve several important and challenging problems in their operations and planning. Meanwhile, probabilistic methods are used for reliability evaluation in these reliability-constrained planning and design. The major problems studied in the dissertation include reliability evaluation of power systems with time-dependent energy sources, multi-objective design of hybrid generation systems, risk and cost tradeoff in economic dispatch with wind power penetration, optimal placement of distributed generators and protective devices in power distribution systems, and reliability-based estimation of wind power capacity credit. These case studies have demonstrated the viability and effectiveness of computational intelligence based methods in dealing with a set of important problems in this research arena.

Harris, and Edgar Villasenor Franco Conference Name 2006 ACEEE Summer Study on Energy Efficiency in Buildings Date Published 08/2006 Conference Location Pacific Grove, CA Abstract The evolution of government purchasing initiatives in Mexico and China, part of the PEPS (Promoting an Energy-efficient Public Sector) program, demonstrates the need for flexibility in designing energy-efficiency strategies in the public sector. Several years of pursuing a top-down (federally led) strategy in Mexico produced few results, and it was not until the program was restructured in 2004 to focus on municipal-level purchasing that the program gained momentum. Today, a new partnership with the Mexican federal government is leading to an intergovernmental initiative with strong support at the federal level. By contrast, the PEPS purchasing initiative in China was successfully initiated and led at the central government level with strategic support from international experts. The very different success trajectories in these two countries provide valuable lessons for designing country-specific public sector energy-efficiency initiatives. Enabling conditions for any successful public sector purchasing initiative include the existence of mandatory energy-efficiency performance standards, an effective energy-efficiency endorsement labeling program, an immediate need for energy conservation, a simple pilot phase (focusing on a limited number of strategically chosen products), and specialized technical assistance. Top-down purchasing programs are likely to be more successful where there is high-level political endorsement and a national procurement law in place, supported by a network of trained purchasers. Bottom-up (municipally led) purchasing programs require that municipalities have the authority to set their own purchasing policies, and also benefit from existing networks of cities, supported by motivated municipal leaders and trained purchasing officials.

Reliability assessment of active residential solar energy systems, Phase I  

SciTech Connect

Experiences with active solar energy systems in the last few years have, in many cases, been less than encouraging. A quantification of the problem areas discovered in a sampling of the active residential solar energy systems in the state of Colorado is presented. While many problems were found, the potential for easy solution of the problems by design or installation refinement is great. Reported is a summary of the findings of the mechanical inspections of twelve systems during the 1978-79 winter. Only one system operated at its expected mechanical, thermal and economic performance level. Four other systems performed well mechanically, but only one of these had thermal performance meeting design expectations. The remaining seven systems did not work well mechanically or thermally. One significantly raised the utility bill of the residence on which it was installed. Poor system design was found to be the major cause of low performance. Also, installation quality was low and installation errors were frequent. Qualified solar system service was virtually unavailable. Nearly all the problems found were solvable using present technology. The greatest immediate need is for training of designers, installers and service people and support of off-market development of total systems.

This report addresses the general data requirements for reliability analysis of fielded wind turbines and other wind plant equipment. The report provides a rationale for why this data should be collected, a list of the data needed to support reliability and availability analysis, and specific data recommendations for a Computerized Maintenance Management System (CMMS) to support automated analysis. This data collection recommendations report was written by Sandia National Laboratories to address the general data requirements for reliability analysis of operating wind turbines. This report is intended to help develop a basic understanding of the data needed for reliability analysis from a Computerized Maintenance Management System (CMMS) and other data systems. The report provides a rationale for why this data should be collected, a list of the data needed to support reliability and availability analysis, and specific recommendations for a CMMS to support automated analysis. Though written for reliability analysis of wind turbines, much of the information is applicable to a wider variety of equipment and analysis and reporting needs. The 'Motivation' section of this report provides a rationale for collecting and analyzing field data for reliability analysis. The benefits of this type of effort can include increased energy delivered, decreased operating costs, enhanced preventive maintenance schedules, solutions to issues with the largest payback, and identification of early failure indicators.

Achieving A Long Term Business Impact by Improving the Energy Effectiveness and Reliability of Electric Motors  

E-Print Network (OSTI)

Over 100,000 electric motors drive the production equipment throughout a large chemical company. The energy-efficiency and reliability of these motors during their entire life have a decided impact on the company's manufacturing costs and production capability. The Corporate Motor Technology Team (CMTT) conceived and led a program to optimize the cost effectiveness and reliability of new motors and developed criteria to determine whether to repair or replace motors that fail. The higher energy efficiency of the electric motors offered by vendors today plays a crucial role in these decisions. The company's current motor specification, procurement, maintenance, repair and replacement practices are vastly improved and consistent across the corporation. The 1995 savings attributed to the higher energy efficiency of over 2000 motors installed the prior year amount to $570,000 and will continue to accrue year after year. So will the savings stemming from lower maintenance cost and reduced downtime.

E-Print Network (OSTI)

The computation of the dependability measures is a crucial point in the planning and development of a wind farm. In this paper we address the issue of energy production by wind turbine by using an indexed semi-Markov chain as a model of wind speed. We present the mathematical model, we describe the data and technical characteristics of a commercial wind turbine (Aircon HAWT-10kW). We show how to compute some of the main dependability measures such as reliability, availability and maintainability functions. We compare the results of the model with real energy production obtained from data available in the Lastem station (Italy) and sampled every 10 minutes.

General reliability and safety methodology and its application to wind energy conversion systems  

DOE Green Energy (OSTI)

In conventional system reliability calculations, each component may be in the Operable state or the Under Repair state. These calculations derive system unavailability, or the probability of the system's being down for repairs. By introducing a third component state between Operable and Under Repair - namely, Defective, But Defect Undetected - the methods developed in this report enable system safety projections to be made in addition to availability projections. Also provided is a mechanism for computing the effect of inspection schedules on both safety and availability. A Reliability and Safety Program (RASP) is detailed which performs these computations and also calculates costs for system inspections and repairs. RASP is applied to a simplified wind energy conversion system example.

DOE Green Energy (OSTI)

Circuit and energy storage transformer configurations are developed to match high impedance loads to low impedance sources. With the secondary open, a large di/dt is produced in the primary circuit by inserting a resistance, characteristic of an opening switch, and the load circuit is connected using a preset spark gap. Transformer design concepts using a foil-MYLAR ''sandwich'' for the secondary winding are described, permitting close primary-secondary coupling. Transformer experiments driven by a 0.25 MJ capacitor bank support the overall system concepts. A compact flux compression generator-transformer system is described.

Impact of Distributed Energy Resources on the Reliability of a Critical Telecommunications Facility  

DOE Green Energy (OSTI)

Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages, as documented by analyses of Federal Communications Commission (FCC) outage reports by the National Reliability Steering Committee (under auspices of the Alliance for Telecommunications Industry Solutions). There are two major issues that are having increasing impact on the sensitivity of the power distribution to telecommunication facilities: deregulation of the power industry, and changing weather patterns. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. But does the diversity in power sources actually increase the reliability of offered power to the office equipment, or does the complexity of installing and managing the extended power system induce more potential faults and higher failure rates? This report analyzes a system involving a telecommunications facility consisting of two switch-bays and a satellite reception system.

Impact of Distributed Energy Resources on the Reliability of Critical Telecommunications Facilities: Preprint  

DOE Green Energy (OSTI)

This paper documents a probabilistic risk assessment of existing and alternative power supply systems at a large telecommunications office. The analysis characterizes the increase in the reliability of power supply through the use of two alternative power configurations. Failures in the power systems supporting major telecommunications service nodes are a main contributor to significant telecommunications outages. A logical approach to improving the robustness of telecommunication facilities is to increase the depth and breadth of technologies available to restore power during power outages. Distributed energy resources such as fuel cells and gas turbines could provide additional on-site electric power sources to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Replacement energy, capacity, and reliability costs for permanent nuclear reactor shutdowns  

SciTech Connect

Average replacement power costs are estimated for potential permanent shutdowns of nuclear electricity-generating units. Replacement power costs are considered to include replacement energy, capacity, and reliability cost components. These estimates were developed to assist the US Nuclear Regulatory Commission in evaluating regulatory issues that potentially affect changes in serious reactor accident frequencies. Cost estimates were derived from long-term production-cost and capacity expansion simulations of pooled utility-system operations. Factors that affect replacement power cost, such as load growth, replacement sources of generation, and capital costs for replacement capacity, were treated in the analysis. Costs are presented for a representative reactor and for selected subcategories of reactors, based on estimates for 112 individual reactors.

The CPUC envisions that funding {open_quotes}would only be needed for specific and limited periods of time to cause the market to be transformed{close_quotes}. At the same time, the CPUC also acknowledges that {open_quotes}there are many definitions of market transformation{close_quotes} ... and does {open_quotes}not attempt to refine those definitions today{close_quotes}. We argue that a definition of market transformation is essential. The literature is now replete with definitions, and an operational definition is needed for the CPUC to decide on which programs should be supported with public funds. The CPUC decision initially indicated a preference for programs that do not provide financial assistance 4-efficiency programs that rely on financial assistance to customers. However, energy customers have traditionally accounted for a substantial portion of California utility`s DSM programs, so the CPUC`s direction to use ratepayer funds to support programs that will transform the market raises critical questions about how to analyze what has happened in order to plan effectively for the future: Which utility energy-efficiency programs, including those that provide financial assistance to customers, have had market transforming effects? To what extent do current regulatory rules and practices encourage or discourage utilities from running programs that are designed to transform the market? Should the rules and programs be modified, and, if so, how, to promote market transformation?

Non-locality of energy separating transformations for Dirac electrons in a magnetic field  

E-Print Network (OSTI)

We investigate a non-locality of Moss-Okninski transformation (MOT) used to separate positive and negative energy states in the 3+1 Dirac equation for relativistic electrons in the presence of a magnetic field. Properties of functional kernels generated by the MOT are analyzed and kernel non-localities are characterized by calculating their second moments parallel and perpendicular to the magnetic field. Transformed functions are described and investigated by computing their variances. It is shown that the non-locality of the energy-separating transformation in the direction parallel to the magnetic field is characterized by the Compton wavelength $\\lambda_c=\\hbar/mc$. In the plane transverse to magnetic field the non-locality depends both on magnetic radius $L=(\\hbar/eB)^{1/2}$ and $\\lambda_c$. The non-locality of MO transformation for the 2+1 Dirac equation is also considered.

Transforming our Nation's Transforming our Nation's Energy System With all the benefits associated with renewable energy, why hasn't the grid already been modernized to accommodate these clean sources of energy? The short answer is: Megawatt-scale integration is hard to find. Our nation's existing power grid is crucial to our way of life and cannot be shut down, overhauled, and started back up again. Yet, critical to moving clean energy technologies onto the electrical grid is the ability to carry out research, development, and megawatt-scale testing of the complex integrated systems, devices, and concepts of future electric supply and demand systems.

Vision for cross-layer optimization to address the dual challenges of energy and reliability  

Science Conference Proceedings (OSTI)

We are rapidly approaching an inflection point where the conventional target of producing perfect, identical transistors that operate without upset can no longer be maintained while continuing to reduce the energy per operation. With power requirements already limiting chip performance, continuing to demand perfect, upset-free transistors would mean the end of scaling benefits. The big challenges in device variability and reliability are driven by uncommon tails in distributions, infrequent upsets, one-size-fits-all technology requirements, and a lack of information about the context of each operation. Solutions co-designed across traditional layer boundaries in our system stack can change the game, allowing architecture and software (a) to compensate for uncommon variation, environments, and events, (b) to pass down invariants and requirements for the computation, and (c) to monitor the health of collections of deVices. Cross-layer codesign provides a path to continue extracting benefits from further scaled technologies despite the fact that they may be less predictable and more variable. While some limited multi-layer mitigation strategies do exist, to move forward redefining traditional layer abstractions and developing a framework that facilitates cross-layer collaboration is necessary.

Impact of distributed energy resources on the reliability of a critical telecommunications facility.  

DOE Green Energy (OSTI)

This report documents a probabilistic risk assessment of an existing power supply system at a large telecommunications office. The focus is on characterizing the increase in the reliability of power supply through the use of two alternative power configurations. Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Energy-Efficient Dry-Type Distribution Transformers: New Opportunities to Cut Energy Bills and Lock-in Long-Term Energy Savings  

E-Print Network (OSTI)

Nearly 90% of the electricity that powers the industrial sector flows through dry-type distribution transformers. These transformers are very efficient- most convert in excess of 95% of input power to output power. However, because transformers are generally energized 24 hours per day, 365 days per year, even small efficiency improvements can yield big energy and dollar savings for power users. Until now, energy-efficient dry-type transformers have been hard to identify. As a result, most users either have failed to specify efficiency at all or relied on the imperfect indicator of low temperature rise. Most manufactures have not offered an "energy-efficient" product line. Now, the National Electrical Manufacturers' Association (NEMA), the transformer manufacturers' trade association, has published a standard defining energy-efficient transformers. This new standard, NEMA standard TP-1, makes it easier for vendors, specifiers, contractors and end-users to identify and determine the cost-effectiveness of energy-efficient transformers. In addition, some manufacturers are beginning to offer equipment lines specifically designed to meet the energy efficiency levels defined in NEMA standard TP-1.

The temperature dependence of the dielectric permittivity is taken into account to study the energy change in a capacitor that follows a cycle between a cold and a hot thermal reservoirs. There is a net energy gain in the process that, in principle, can be transformed into usable work. The article is simple enough as to be used with keen undergraduates that have taken a university general physics or thermodynamics course. Further experimental work and a possible technological application are suggested.

Fundamental limits on energy transfer and circuit considerations for piezoelectric transformers  

E-Print Network (OSTI)

Abstract—This work investigates fundamental limits on electromechanical energy conversion capacity of piezoelectric transformers by considering a work cycle analysis. Fundamental limitations in a lossless piezoelectric transformer are imposed by maximum electric field strength, maximum surface charge density, maximum stress, and maximum strain. For the lossless case, our analysis indicates that the mechanical stress limit is the effective constraint in typical PZT materials. For a specific PZT-5H sample considered, a mechanical stress-limited work cycle indicates that this material can handle 330 W/cm3 at 100 kHz. A second direction this work has taken has been an investigation into a soft-switching drive and control circuit, that does not require any magnetic components. The theory of operation of softswitching resonant drive circuitry is discussed, and experimental results on a soft-switching inverter incorporating no magnetic components are reported. Index Terms—Piezoelectric, soft-switching, transformer, work cycle.

Technology Prioritization: Transforming the U.S. Building Stock to Embrace Energy Efficiency  

SciTech Connect

The U.S. Buildings sector is responsible for about 40% of the national energy expenditures. This is due in part to wasteful use of resources and limited considerations made for energy efficiency during the design and retrofit phases. Recent studies have indicated the potential for up to 30-50% energy savings in the U.S. buildings sector using currently available technologies. This paper discusses efforts to accelerate the transformation in the U.S. building energy efficiency sector using a new technology prioritization framework. The underlying analysis examines building energy use micro segments using the Energy Information Administration Annual Energy Outlook and other publically available information. The tool includes a stock-and-flow model to track stock vintage and efficiency levels with time. The tool can be used to investigate energy efficiency measures under a variety of scenarios and has a built-in energy accounting framework to prevent double counting of energy savings within any given portfolio. This tool is developed to inform decision making and estimate long term potential energy savings for different market adoption scenarios.

Reliability and maintainability study of select solar-energy-system components in the National Solar Data Network. Final subcontract report  

Science Conference Proceedings (OSTI)

This study reports on the reliability and maintainability of select solar energy system components evaluated in 16 solar heating and cooling systems over a one-year period. The systems evaluated were instrumented sites from the National Solar Data Network (NSDN). A complete description and system schematic for each site is provided. The study period was generally between October 1981 to October 1982. The report provides quantitative R and M data (e.g., Failure Rate and Mean Time Between Failures) on pumps, motors and fans from the selected NSDN sites, along with conclusions and recommendations based on comparative data for other components. In summary, pumps, valves, and heat exchangers in solar heating and cooling (SHAC) systems appear to be very reliable and show failure rates comparable to other mechanical system applications. Control systems typically used in SHAC systems appear to be the least reliable but still fall within the range of failures exhibited by other mechanical systems. Evidence suggests that piping leaks in SHAC systems occur at three times the rate of other mechanical systems. Recommendations are provided on other areas of research necessary to determine the useful life of SHAC system components. Finally, an appendix to this report describes actual failures encountered in the 16 systems evaluated.

In this paper we consider the problem of wind energy production using a second order semi-Markov chain in state and duration as a model of wind speed. We present the mathematical model, we describe the data and technical characteristics of a commercial wind turbine (Aircon HAWT-10kW). We show how to compute some of the main dependability measures such as reliability, availability and maintainability functions. We compare the results of the model with real energy production obtained from data available in the Lastem station (Italy) and sampled every 10 minutes. The computation of the dependability measures is a crucial point in the planning and development of a wind farm.

To reduce petroleum consumption, Fort Carson is considering grid-connected vehicles (GCVs) such as pure electric trucks to replace some of its on-base truck fleet. As the availability and affordability of distributed renewable energy generation options increase, so will the GCV options (currently, three all-electric trucks are available on the GSA schedule). The presence of GCVs on-base opens up the possibility to utilize these vehicles to provide stability to the base micro-grid. This poster summarizes work to estimate the potential impacts of three electric vehicle grid interactions between the electric truck fleet and the Fort Carson micro-grid: 1) full-power charging without management, 2) full-power charging capability controlled by the local grid authority, and 3) full-power charge and discharge capability controlled by the local grid authority. We found that even at relatively small adoption rates, the control of electric vehicle charging at Fort Carson will aid in regulation of variable renewable generation loads and help stabilize the micro-grid.

Advanced Heat Transfer Technologies Increase Vehicle Performance and Reliability, The Spectrum of Clean Energy Innovation (Fact Sheet)  

NLE Websites -- All DOE Office Websites (Extended Search)

Advanced Heat Transfer Advanced Heat Transfer Technologies Increase Vehicle Performance and Reliability Keeping yourself cool while driving your car on a hot, sunny day can be a challenge. But it can be even more challenging to cool the power electronic components that are critically important in hybrid electric and all-electric vehicles. Researchers at the National Renewable Energy Laboratory (NREL) investigate and develop these vehicles and their components to help reduce our use of imported petroleum and curb the emissions associated with climate change. A vehicle's power electronic components include the motor controller, converters, and inverters that condition the flow of electrical power between the battery and the electric motor. The problem is that power electronics generate a lot of heat. This heat can decrease

Science Conference Proceedings (OSTI)

In 2009, Transformations, Inc. partnered with U.S. Department of Energy (DOE) Building America team Building Science Corporation (BSC) to build new net zero energy houses in three developments in Massachusetts. The company has been developing strategies for cost-effective super-insulated homes in the New England market since 2006. After years of using various construction techniques, it has developed a specific set of assemblies and specifications that achieve a 44.9% reduction in energy use compared with a home built to the 2009 International Residential Code, qualifying the houses for the DOE's Challenge Home. The super-insulated houses provide data for several research topics in a cold climate. BSC studied the moisture risks in double stud walls insulated with open cell spray foam and cellulose. The mini-split air source heat pump (ASHP) research focused on the range of temperatures experienced in bedrooms as well as the homeowners' perceptions of equipment performance. BSC also examined the developer's financing options for the photovoltaic (PV) systems, which take advantage of Solar Renewable Energy Certificates, local incentives, and state and federal tax credits.

Transformation of the single energy group transport, equation to axissymmetric toroidal coordinates  

SciTech Connect

The streaming term of the single energy group transport equation was derived for a general class of axisymmetric toroidal geometries using a tensor transformation formalism. The particular case of nested circular toroids treated previously by Pomraning and Stevens may be obtained by direct substitution into the equation. Other, more complicated geometries of interest to plasma physics and fusion reactor research are obtainable in the same manner. The cylindrical limit in which the azimuthal curvature is neglected may be obtained by taking the ratio of the poloidal curvature to X$sup 1$, the toroidal curvature, to zero. Similarly the planar limit results when both curvatures are small compared to the inverse of the physical dimension measured normal to the toroidal surface. (auth)

Challenges to Integration of Safety and Reliability with Proliferation Resistance and Physical Protection for Generation IV Nuclear Energy Systems  

Science Conference Proceedings (OSTI)

The optimization of a nuclear energy system's performance requires an integrated consideration of multiple design goals - sustainability, safety and reliability (S&R), proliferation resistance and physical protection (PR&PP), and economics - as well as careful evaluation of trade-offs for different system design and operating parameters. Design approaches motivated by each of the goal areas (in isolation from the other goal areas) may be mutually compatible or in conflict. However, no systematic methodology approach has yet been developed to identify and maximize synergies and optimally balance conflicts across the possible design configurations and operating modes of a nuclear energy system. Because most Generation IV systems are at an early stage of development, design, and assessment, designers and analysts are only beginning to identify synergies and conflicts between PR&PP, S&R, and economics goals. The close coupling between PR&PP and S&R goals has motivated early attention within the Generation IV International Forum to their integrated consideration to facilitate the optimization of their effects and the minimization of potential conflicts. This paper discusses the status of this work.

CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights  

Science Conference Proceedings (OSTI)

Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

Photovoltaic module reliability workshop  

DOE Green Energy (OSTI)

The paper and presentations compiled in this volume form the Proceedings of the fourth in a series of Workshops sponsored by Solar Energy Research Institute (SERI/DOE) under the general theme of photovoltaic module reliability during the period 1986--1990. The reliability Photo Voltaic (PV) modules/systems is exceedingly important along with the initial cost and efficiency of modules if the PV technology has to make a major impact in the power generation market, and for it to compete with the conventional electricity producing technologies. The reliability of photovoltaic modules has progressed significantly in the last few years as evidenced by warranties available on commercial modules of as long as 12 years. However, there is still need for substantial research and testing required to improve module field reliability to levels of 30 years or more. Several small groups of researchers are involved in this research, development, and monitoring activity around the world. In the US, PV manufacturers, DOE laboratories, electric utilities and others are engaged in the photovoltaic reliability research and testing. This group of researchers and others interested in this field were brought together under SERI/DOE sponsorship to exchange the technical knowledge and field experience as related to current information in this important field. The papers presented here reflect this effort.

Component reliability testing  

SciTech Connect

Component and system reliability of active solare energy systems continues to be a major concern of designers, manufacturers, installers, and consumers. Six test loops were constructed at the Solar Energy Research Institute in Golden, Colorado, to thermally cycle active solar energy system components. Drain valves, check valves, air vents, vacuum breakers, tempering valves, and polybutylene pipe were included in the testing. Test results show poor reliabiity of some of the components and limited performance from others. The results lead to a better understanding of certain failures in the field and present designers with realistic expectations for these components.

State of the States 2010: The Role of Policy in Clean Energy Market Transformation  

SciTech Connect

This report builds on the emerging body of literature seeking to identify quantitative connections between clean energy policy and renewable energy. The methods presented test the relationships between a broad set of policies and clean energy resources (energy efficiency, biomass, geothermal, solar, and wind). Energy efficiency findings are an initial foray into this type of analysis and indicate significant connections between reduced energy use and buildings codes, energy efficiency resource standards (in some cases), and electricity price. Renewable energy findings specify that there is most often a relationship between state policies and solar and wind development, indicating that while policies might apply to a wide variety of renewable resources, further tailoring of policy specifics to resource needs may lead to increased development of a wider variety of renewable energy resources. Further research is needed to refine the connections between clean energy development and policy, especially in the area of the impact of the length of time that a policy has been in place.

Lorentz Transformations  

E-Print Network (OSTI)

This paper describes a particularly didactic and transparent derivation of basic properties of the Lorentz group. The generators for rotations and boosts along an arbitrary direction, as well as their commutation relations, are written as functions of the unit vectors that define the axis of rotation or the direction of the boost (an approach that can be compared with the one that in electrodynamics, works with the electric and magnetic fields instead of the Maxwell stress tensor). For finite values of the angle of rotation or the boost's velocity, collectively denoted by V, the existence of an exponential expansion for the coordinate transformation's matrix, M (in terms of GV where G is the generator) requires that the matrix's derivative with respect to V, be equal to GM. This condition can only be satisfied if the transformation is additive as it is indeed the case for rotations, but not for velocities. If it is assumed, however, that for boosts such an expansion exists, with V = V(v), v being the velocity, and if the above condition is imposed on the boost's matrix then its expression in terms of hyperbolic cosh(V) and sinh(V} is recovered, and the expression for V(= arc tanh(v)) is determined. A general Lorentz transformation can be written as an exponential containing the sum of a rotation and a boost, which to first order is equal to the product of a boost with a rotation. The calculations of the second and third order terms show that the equations for the generators used in this paper, allow to reliably infer the expressions for the higher order generators, without having recourse to the commutation relations. The transformationmatrices for Weyl spinors are derived for finite values of the rotation and velocity, and field representations, leading to the expression for the angular momentum operator, are studied.

Two Paths to Transforming Markets through Public Sector EnergyEfficiency: Bottom Up versus Top Down  

SciTech Connect

The evolution of government purchasing initiatives in Mexicoand China, part of the PEPS (Promoting an Energy-efficient Public Sector)program, demonstrates the need for flexibility in designingenergy-efficiency strategies in the public sector. Several years ofpursuing a top-down (federally led) strategy in Mexico produced fewresults, and it was not until the program was restructured in 2004 tofocus on municipal-level purchasing that the program gained momentum.Today, a new partnership with the Mexican federal government is leadingto an intergovernmental initiative with strong support at the federallevel. By contrast, the PEPS purchasing initiative in China wassuccessfully initiated and led at the central government level withstrategic support from international experts. The very different successtrajectories in these two countries provide valuable lessons fordesigning country-specific public sector energy-efficiency initiatives.Enabling conditions for any successful public sector purchasinginitiative include the existence of mandatory energy-efficiencyperformance standards, an effective energy-efficiency endorsementlabeling program, an immediate need for energy conservation, a simplepilot phase (focusing on a limited number of strategically chosenproducts), and specialized technical assistance. Top-down purchasingprograms are likely to be more successful where there is high-levelpolitical endorsement and a national procurement law in place, supportedby a network of trained purchasers. Bottom-up (municipally led)purchasing programs require that municipalities have the authority to settheir own purchasing policies, and also benefit from existing networks ofcities, supported by motivated municipal leaders and trained purchasingofficials.

The interpretation of the optical Appell transformation, as previously elaborated in relation to the free-space paraxial propagation under both a rectangular and a circular cylindrical symmetry, is reviewed. Then, the caloric Appell transformation, well known in the theory of heat equation, is shown to be amenable for a similar interpretation involving the Laplace transform rather than the Fourier transform, when dealing with the 1D heat equation. Accordingly, when considering the radial heat equation, suitably defined Hankel-type transforms come to be involved in the inherent Appell transformation. The analysis is aimed at outlining the link between the Appell transformation and the canonical transforms.

On problems of experimental determination of reliable values of nucleus parameters at low excitation energy - Ni-60 as an example  

E-Print Network (OSTI)

The reanalysis of the published experimental data from reaction Co-59(p,2gamma)Ni-60 was performed. The region of the most probable values of level density and radiative strength functions of cascade gamma-transitions was determined. The obtained data were rather precisely approximated by the V.M. Strutinsky model and semi-phenomenological model - for strength functions. The region of appearance and magnitude of maximal errors of the calculated cross-section of nucleon emission in evaporation spectra in traditional methods of their analysis were determined as well. There was for the first time obtained methodically correct information on the radiation strength function of primary gamma-transitions in diapason of neutron binding energy with averaging over large set of initial levels.

We review Darboux-Crum transformation of Heun's differential equation. By rewriting an integral transformation of Heun's differential equation into a form of elliptic functions, we see that the integral representation is a generalization of Darboux-Crum transformation. We also consider conservation of monodromy with respect to the transformations.

Natural Gas and the Transformation of the U.S. Energy Sector: Electricity  

Science Conference Proceedings (OSTI)

The Joint Institute for Strategic Energy Analysis (JISEA) designed this study to address four related key questions, which are a subset of the wider dialogue on natural gas: 1. What are the life cycle greenhouse gas (GHG) emissions associated with shale gas compared to conventional natural gas and other fuels used to generate electricity?; 2. What are the existing legal and regulatory frameworks governing unconventional gas development at federal, state, and local levels, and how are they changing in response to the rapid industry growth and public concerns?; 3. How are natural gas production companies changing their water-related practices?; and 4. How might demand for natural gas in the electric sector respond to a variety of policy and technology developments over the next 20 to 40 years?

Single-transformer substation for 500 kV and over  

SciTech Connect

At extra high voltage substations which must meet high reliability requirements, in particular, two autotransformer groups are often installed almost simultaneously independent of the load. As a result, significant capital investment is frozen for long periods, and scarce electrical equipment is utilized inefficiently. Thus, in a number of cases the construction of substations with a single group of single-phase autotransformers is desirable. In this case, on failure of one autotransformer phase the time of subnormal energy output due to disconnection of the substation may reach several hours. The efficiency of extra high voltage substations may be improved significantly by using a proposed circuit for connection of a group of single-phase transformers with a single reserve phase, permitting installation of one group of single-phase transformers at a substation without impairment of reliability. The installation, performance and cost of this transformer arrangement are discussed. It is concluded that the use of single-transformer 500 kV substations with the proposed circuit as distribution substations would, on the one hand, provide sufficient reliability for users and, on the other hand, would make them competitive with 220 to 330 kV substations. In this case the network reliability can be provided by sectionalizing the lines at the site of transformer connection. This circuit can be used with two-sided substation supply. (LCL)

Power electronics reliability analysis.  

SciTech Connect

This report provides the DOE and industry with a general process for analyzing power electronics reliability. The analysis can help with understanding the main causes of failures, downtime, and cost and how to reduce them. One approach is to collect field maintenance data and use it directly to calculate reliability metrics related to each cause. Another approach is to model the functional structure of the equipment using a fault tree to derive system reliability from component reliability. Analysis of a fictitious device demonstrates the latter process. Optimization can use the resulting baseline model to decide how to improve reliability and/or lower costs. It is recommended that both electric utilities and equipment manufacturers make provisions to collect and share data in order to lay the groundwork for improving reliability into the future. Reliability analysis helps guide reliability improvements in hardware and software technology including condition monitoring and prognostics and health management.

Smart Grid - Transforming Power System Operations  

SciTech Connect

Abstract—Electric power systems are entering a new realm of operations. Large amounts of variable generation tax our ability to reliably operate the system. Couple this with a greater reliance on the electricity network to serve consumer demand that is likely to rise significantly even as we drive for greater efficiency. Trade-offs between energy and environmental needs will be constantly negotiated, while a reliable supply of electricity needs even greater assurance in a world where threats of disruption have risen. Smart grid capabilities are being proposed to help address the challenges confronting system operations. This paper reviews the impact of smart grid functionality on transforming power system operations. It explores models for distributed energy resources (DER – generation, storage, and load) that are appearing on the system. It reviews the evolving nature of electricity markets to deal with this complexity and a change of emphasis on signals from these markets to affect power system control. Smart grid capabilities will also impact reliable operations, while cyber security issues must be addressed as a culture change that influences all system design, implementation, and maintenance. Lastly, the paper explores significant questions for further research and the need for a simulation environment that supports such investigation and informs deployments to mitigate operational issues as they arise.

Virtually simulating the next generation of clean energy technologies: NETL's AVESTAR Center is dedicated to the safe, reliable and efficient operation of advanced energy plants with carbon capture  

SciTech Connect

Imagine using a real-time virtual simulator to learn to fly a space shuttle or rebuild your car's transmission without touching a piece of equipment or getting your hands dirty. Now, apply this concept to learning how to operate and control a state-of-the-art, electricity-producing power plant capable of carbon dioxide (CO{sub 2}) capture. That's what the National Energy Technology Laboratory's (NETL) Advanced Virtual Energy Simulation Training and Research (AVESTAR) Center (www.netl.doe.gov/avestar) is designed to do. Established as part of the Department of Energy's (DOE) initiative to advance new clean energy technology for power generation, the AVESTAR Center focuses primarily on providing simulation-based training for process engineers and energy plant operators, starting with the deployment of a first-of-a-kind operator training simulator for an integrated gasification combined cycle (IGCC) power plant with CO{sub 2} capture. The IGCC dynamic simulator builds on, and reaches beyond, conventional power plant simulators to merge, for the first time, a 'gasification with CO{sub 2} capture' process simulator with a 'combined-cycle' power simulator. Based on Invensys Operations Management's SimSci-Esscor DYNSIM software, the high-fidelity dynamic simulator provides realistic training on IGCC plant operations, including normal and faulted operations, as well as plant start-up, shutdown and power demand load changes. The highly flexible simulator also allows for testing of different types of fuel sources, such as petcoke and biomass, as well as co-firing fuel mixtures. The IGCC dynamic simulator is available at AVESTAR's two locations, NETL (Figure 1) and West Virginia University's National Research Center for Coal and Energy (www.nrcce.wvu.edu), both in Morgantown, W.Va. By offering a comprehensive IGCC training program, AVESTAR aims to develop a workforce well prepared to operate, control and manage commercial-scale gasification-based power plants with CO{sub 2} capture. The facility and simulator at West Virginia University promotes NETL's outreach mission by offering hands-on simulator training and education to researchers and university students.

Lightweight transformer  

DOE Green Energy (OSTI)

The technical effort described in this report relates to the program that was performed to design, fabricate, and test a lightweight transformer for Strategic Defense Initiative Organization (SDIO) mission requirements. The objectives of this program were two-fold: (1) design and fabricate a lightweight transformer using liquid hydrogen as the coolant; and (2) test the completed transformer assembly with a low voltage, dc power source. Although the full power testing with liquid helium was not completed, the program demonstrated the viability of the design approach. The lightweight transformer was designed and fabricated, and low and moderate power testing was completed. The transformer is a liquid hydrogen cooled air core transformer that uses thin copper for its primary and secondary windings. The winding mass was approximately 12 kg, or 0.03 kg/kW. Further refinements of the design to a partial air core transformer could potentially reduce the winding mass to as low as 4 or 5 kg, or 0.0125 kg/kW. No attempt was made on this program to reduce the mass of the related structural components or cryogenic container. 8 refs., 39 figs., 2 tabs.

Hawaii electric system reliability.  

SciTech Connect

This report addresses Hawaii electric system reliability issues; greater emphasis is placed on short-term reliability but resource adequacy is reviewed in reference to electric consumers' views of reliability "worth" and the reserve capacity required to deliver that value. The report begins with a description of the Hawaii electric system to the extent permitted by publicly available data. Electrical engineering literature in the area of electric reliability is researched and briefly reviewed. North American Electric Reliability Corporation standards and measures for generation and transmission are reviewed and identified as to their appropriateness for various portions of the electric grid and for application in Hawaii. Analysis of frequency data supplied by the State of Hawaii Public Utilities Commission is presented together with comparison and contrast of performance of each of the systems for two years, 2010 and 2011. Literature tracing the development of reliability economics is reviewed and referenced. A method is explained for integrating system cost with outage cost to determine the optimal resource adequacy given customers' views of the value contributed by reliable electric supply. The report concludes with findings and recommendations for reliability in the State of Hawaii.

A Reliable Natural Language Interface  

E-Print Network (OSTI)

As household appliances grow in complexity and sophistication, they become harder and harder to use, particularly because of their tiny display screens and limited keyboards. This paper describes a strategy for building natural language interfaces to appliances that circumvents these problems. Our approach leverages decades of research on planning and natural language interfaces to databases by reducing the appliance problem to the database problem; the reduction provably maintains desirable properties of the database interface. The paper goes on to describe the implementation and evaluation of the EXACT interface to appliances, which is based on this reduction. EXACT maps each English user request to an SQL query, which is transformed to create a PDDL goal, and uses the Blackbox planner [13] to map the planning problem to a sequence of appliance commands that satisfy the original request. Both theoretical arguments and experimental evaluation show that EXACT is highly reliable.

SUPPLEMENT TO THE THIRD QUARTERLY REPORT ON THE ECONOMIC IMPACT OF THE AMERICAN RECOVERY AND REINVESTMENT ACT OF 2009 THE ARRA AND THE CLEAN ENERGY TRANSFORMATION  

E-Print Network (OSTI)

A central piece of the American Recovery and Reinvestment Act of 2009 (ARRA) is more than $90 billion in government investment and tax incentives to lay the foundation for the clean energy economy of the future. As discussed in CEA’s Second Quarterly Report on the impact of the ARRA, this investment will help create a new generation of jobs, reduce dependence on oil, enhance national security, and improve the environment. 1 Ultimately, the investments could help transform the United States into a global clean energy leader. The ARRA clean energy investments are also providing crucial stimulus to the economy. Through programs such as enhanced tax credits for homeowners who make energy-efficient improvements, funding for research into new clean energy technologies, or grants to qualifying businesses, these investments are generating economic activity and creating new employment opportunities. This supplement to the CEA’s Third Quarterly Report updates our estimates of the effect of the ARRA’s clean energy provisions on economic recovery through the first quarter of 2010. We find that the Recovery Act directly created more than 80,000 clean energy jobs in the first quarter of 2010, and that the clean energy investments supported an additional 20,000

Grid reliability management tools  

SciTech Connect

To summarize, Consortium for Electric Reliability Technology Solutions (CERTS) is engaged in a multi-year program of public interest R&D to develop and prototype software tools that will enhance system reliability during the transition to competitive markets. The core philosophy embedded in the design of these tools is the recognition that in the future reliability will be provided through market operations, not the decisions of central planners. Embracing this philosophy calls for tools that: (1) Recognize that the game has moved from modeling machine and engineering analysis to simulating markets to understand the impacts on reliability (and vice versa); (2) Provide real-time data and support information transparency toward enhancing the ability of operators and market participants to quickly grasp, analyze, and act effectively on information; (3) Allow operators, in particular, to measure, monitor, assess, and predict both system performance as well as the performance of market participants; and (4) Allow rapid incorporation of the latest sensing, data communication, computing, visualization, and algorithmic techniques and technologies.

Delivery and Energy Reliability, Permitting, Siting and Analysis of the U.S. Department of Energy under Contract No. DE-AC02-05CH11231. Quantitative Financial Analysis of Alternative Energy Efficiency Shareholder Incentive Mechanisms  

E-Print Network (OSTI)

Rising energy prices and climate change are central issues in the debate about our nation’s energy policy. Many are demanding increased energy efficiency as a way to help reduce greenhouse gas emissions and lower the total cost of electricity and energy services for consumers and businesses. Yet, as the National Action Plan on Energy Efficiency (NAPEE) pointed out, many utilities continue to shy away from seriously expanding their energy efficiency program offerings because they claim there is insufficient profit-motivation, or even a financial disincentive, when compared to supply-side investments. With the recent introduction of Duke Energy’s Save-a-Watt incentive mechanism and ongoing discussions about decoupling, regulators and policymakers are now faced with an expanded and diverse landscape of financial incentive mechanisms, Determining the “right” way forward to promote deep and sustainable demand side resource programs is challenging. Due to the renaissance that energy efficiency is currently experiencing, many want to better understand the tradeoffs in stakeholder benefits between these alternative incentive structures before aggressively embarking on a path for which course corrections can be time-consuming

Power electronics reliability.  

Science Conference Proceedings (OSTI)

The project's goals are: (1) use experiments and modeling to investigate and characterize stress-related failure modes of post-silicon power electronic (PE) devices such as silicon carbide (SiC) and gallium nitride (GaN) switches; and (2) seek opportunities for condition monitoring (CM) and prognostics and health management (PHM) to further enhance the reliability of power electronics devices and equipment. CM - detect anomalies and diagnose problems that require maintenance. PHM - track damage growth, predict time to failure, and manage subsequent maintenance and operations in such a way to optimize overall system utility against cost. The benefits of CM/PHM are: (1) operate power conversion systems in ways that will preclude predicted failures; (2) reduce unscheduled downtime and thereby reduce costs; and (3) pioneering reliability in SiC and GaN.

Final report for CCS cross-layer reliability visioning study  

SciTech Connect

The geometric rate of improvement of transistor size and integrated circuit performance known as Moore's Law has been an engine of growth for our economy, enabling new products and services, creating new value and wealth, increasing safety, and removing menial tasks from our daily lives. Affordable, highly integrated components have enabled both life-saving technologies and rich entertainment applications. Anti-lock brakes, insulin monitors, and GPS-enabled emergency response systems save lives. Cell phones, internet appliances, virtual worlds, realistic video games, and mp3 players enrich our lives and connect us together. Over the past 40 years of silicon scaling, the increasing capabilities of inexpensive computation have transformed our society through automation and ubiquitous communications. Looking forward, increasing unpredictability threatens our ability to continue scaling integrated circuits at Moore's Law rates. As the transistors and wires that make up integrated circuits become smaller, they display both greater differences in behavior among devices designed to be identical and greater vulnerability to transient and permanent faults. Conventional design techniques expend energy to tolerate this unpredictability by adding safety margins to a circuit's operating voltage, clock frequency or charge stored per bit. However, the rising energy costs needed to compensate for increasing unpredictability are rapidly becoming unacceptable in today's environment where power consumption is often the limiting factor on integrated circuit performance and energy efficiency is a national concern. Reliability and energy consumption are both reaching key inflection points that, together, threaten to reduce or end the benefits of feature size reduction. To continue beneficial scaling, we must use a cross-layer, Jull-system-design approach to reliability. Unlike current systems, which charge every device a substantial energy tax in order to guarantee correct operation in spite of rare events, such as one high-threshold transistor in a billion or one erroneous gate evaluation in an hour of computation, cross-layer reliability schemes make reliability management a cooperative effort across the system stack, sharing information across layers so that they only expend energy on reliability when an error actually occurs. Figure 1 illustrates an example of such a system that uses a combination of information from the application and cheap architecture-level techniques to detect errors. When an error occurs, mechanisms at higher levels in the stack correct the error, efficiently delivering correct operation to the user in spite of errors at the device or circuit levels. In the realms of memory and communication, engineers have a long history of success in tolerating unpredictable effects such as fabrication variability, transient upsets, and lifetime wear using information sharing, limited redundancy, and cross-layer approaches that anticipate, accommodate, and suppress errors. Networks use a combination of hardware and software to guarantee end-toend correctness. Error-detection and correction codes use additional information to correct the most common errors, single-bit transmission errors. When errors occur that cannot be corrected by these codes, the network protocol requests re-transmission of one or more packets until the correct data is received. Similarly, computer memory systems exploit a cross-layer division of labor to achieve high performance with modest hardware. Rather than demanding that hardware alone provide the virtual memory abstraction, software page-fault and TLB-miss handlers allow a modest piece of hardware, the TLB, to handle the common-case operations on a cyc1e-by-cycle basis while infrequent misses are handled in system software. Unfortunately, mitigating logic errors is not as simple or as well researched as memory or communication systems. This lack of understanding has led to very expensive solutions. For example, triple-modular redundancy masks errors by triplicating computations in either time or area. T

Measurement Practices for Reliability and Power Quality  

DOE Green Energy (OSTI)

This report provides a distribution reliability measurement ''toolkit'' that is intended to be an asset to regulators, utilities and power users. The metrics and standards discussed range from simple reliability, to power quality, to the new blend of reliability and power quality analysis that is now developing. This report was sponsored by the Office of Electric Transmission and Distribution, U.S. Department of Energy (DOE). Inconsistencies presently exist in commonly agreed-upon practices for measuring the reliability of the distribution systems. However, efforts are being made by a number of organizations to develop solutions. In addition, there is growing interest in methods or standards for measuring power quality, and in defining power quality levels that are acceptable to various industries or user groups. The problems and solutions vary widely among geographic areas and among large investor-owned utilities, rural cooperatives, and municipal utilities; but there is still a great degree of commonality. Industry organizations such as the National Rural Electric Cooperative Association (NRECA), the Electric Power Research Institute (EPRI), the American Public Power Association (APPA), and the Institute of Electrical and Electronics Engineers (IEEE) have made tremendous strides in preparing self-assessment templates, optimization guides, diagnostic techniques, and better definitions of reliability and power quality measures. In addition, public utility commissions have developed codes and methods for assessing performance that consider local needs. There is considerable overlap among these various organizations, and we see real opportunity and value in sharing these methods, guides, and standards in this report. This report provides a ''toolkit'' containing synopses of noteworthy reliability measurement practices. The toolkit has been developed to address the interests of three groups: electric power users, utilities, and regulators. The report will also serve to support activities to develop and share information among industry and regulatory participants about critical resources and practices. The toolkit has been developed by investigating the status of indices and definitions, surveying utility organizations on information sharing, and preparing summaries of reliability standards and monitoring requirements--the issues, needs, work under way, existing standards, practices and guidelines--for the following three classifications: (1) terms and definitions of reliability; (2) power quality standards, guidelines, and measurements; and (3) activities and organizations developing and sharing information on distribution reliability. As these synopses of reliability measurement practices are provided, it must be noted that an economic penalty may be associated with requiring too high a reliability level from the distribution system for all customers. It may be appropriate for the distribution system to supply only some base, generally accepted level of reliability. This base level would be adequate for the majority of customers. Users who need a higher level may find it economical to supply using distributed energy resources (DER) and other local solutions to reliability and power quality needs. Local solutions implemented by the customer may be the most cost-effective method for addressing the more stringent needs of a digital economy. These local solutions include energy storage, small distributed generators, and microgrids. This report also considers the market's role in addressing reliability issues and requirements. The customer's needs are discussed in view of issues such as power quality requirements of digital electronic equipment, the cost of outages, the cost of storage and new infrastructure, and natural gas prices. The market role in addressing these issues and requirements is explored. The economic considerations associated with the reliability issues are discussed, as well as the levels at which these economic decisions could be made.

Substation Reliability Centered Maintenance  

SciTech Connect

Substation Reliability Centered Maintenance (RCM) is a technique that is used to develop maintenance plans and criteria so the operational capability of substation equipment is achieved, restored, or maintained. The objective of the RCM process is to focus attention on system equipment in a manner that leads to the formulation of an optimal maintenance plan. The RCM concept originated in the airline industry in the 1970s and has been used since 1985 to establish maintenance requirements for nuclear power plants. The RCM process is initially applied during the design and development phase of equipment or systems on the premise that reliability is a design characteristic. It is then reapplied, as necessary, during the operational phase to sustain a more optimal maintenance program based on actual field experiences. The purpose of the RCM process is to develop a maintenance program that provides desired or specified levels of operational safety and reliability at the lowest possible overall cost. The objectives are to predict or detect and correct incipient failures before they occur or before they develop into major defects, reduce the probability of failure, detect hidden problems, and improve the cost-effectiveness of the maintenance program. RCM accomplishes two basic purposes: (1) It identifies in real-time incipient equipment problems, averting potentially expensive catastrophic failures by communicating potential problems to appropriate system operators and maintenance personnel. (2) It provides decision support by recommending, identifying, and scheduling preventive maintenance. Recommendations are based on maintenance criteria, maintenance history, experience with similar equipment, real-time field data, and resource constraints. Hardware and software are used to accomplish these two purposes. The RCM system includes instrumentation that monitors critical substation equipment as well as computer software that helps analyze equipment data.

The Future of Nuclear Energy: Facts and Fiction Chapter III: How (un)reliable are the Red Book Uranium Resource Data?  

E-Print Network (OSTI)

For more than 40 years, the Nuclear Energy Agency of the OECD countries and the International Atomic Energy Administration of the United Nations have published a biannual document with the title “Uranium Resources, Production and Demand”. This book, known as the “Red Book”, summarizes data about the actual and near future nuclear energy situation and presents the accumulated worldwide knowledge about the existing and expected uranium resources. These data are widely believed to provide an accurate and solid basis for future decisions about nuclear energy. Unfortunately, as it is demonstrated in this paper, they do not. The conventional worldwide uranium resources are estimated by the authors of the Red Book as 5.5 million tons. Out of these, 3.3 million tons are assigned to the reasonable assured category and 2.2 million tons are associated with the not yet discovered but assumed to exist inferred resources. Our analysis shows that neither the 3.3 million tons of “assured ” resources nor the 2.2 million tons of inferred resources are justified by the Red Book data and that the actual known exploitable resources are probably much smaller. Despite many shortcomings of the uranium resource data, some interesting and valuable information can be extracted from the Red Book. Perhaps most importantly, the Red Book resource data can be used to test the “economic-geological hypothesis”, which claims for example that a doubling of uranium price will increase the amount exploitable uranium resources by an even larger factor. The relations between the uranium resources claimed for the different resource categories and their associated cost estimates are found to be in clear contradiction with this hypothesis.

Sustainable Energy Solutions Task 2.0: Wind Turbine Reliability and Maintainability Enhancement through System-wide Structure Health Monitoring and Modifications to Rotating Components  

DOE Green Energy (OSTI)

EXECUTIVE SUMARRY An evaluation of nondestructive structural health monitoring methods was completed with over 132 documents, 37 specifically about wind turbines, summarized into a technology matrix. This matrix lists the technology, what can be monitored with this technology, and gives a short summary of the key aspects of the technology and its application. Passive and active acoustic emission equipment from Physical Acoustics Corp. and Acellent Technologies have been evaluated and selected for use in experimental state loading and fatigue tests of composite wind turbine blade materials. Acoustic Emission (AE) and Active Ultrasonic Testing (AUT), were applied to composite coupons with both simulated and actual damage. The results found that, while composites are more complicated in nature, compared to metallic structures, an artificial neural network analysis could still be used to determine damage. For the AE system, the failure mode could be determined (i.e. fiber breakage, delamination, etc.). The Acellent system has been evaluated to work well with composite materials. A test-rig for reliability testing of the rotating components was constructed. The research on the types of bearings used in the wind turbines indicated that in most of the designs, the main bearings utilized to support the shaft are cylindrical roller bearings. The accelerated degradation testing of a population of bearings was performed. Vibration and acoustic emission data was collected and analyzed in order to identify a representative degradation signal for each bearing to identify the initiation of the degradation process in the bearings. Afterwards, the RMS of the vibration signal from degradation initiation up to the end of the useful life of the bearing was selected to predict the remaining useful life of the bearing. This step included fitting Autoregressive Moving Average (ARMA) models to the degradation signals and approximating the probability distribution function (PDF) of remaining useful life based on the results of Monte-Carlo simulation of the ARMA models. This step was performed for different percentages of the degradation signal of each bearing. The accuracy of the proposed approach then was assessed by comparing the actual life of the bearing and the estimated life of the bearing from the developed models. The results were impressive and indicated that the accuracy of the models improved as more data was utilized in developing the ARMA models (we get closer to the end of the life of the bearing).

Consider insulation reliability  

SciTech Connect

This paper reports that when calcium silicate and two brands of mineral wool were compared in a series of laboratory tests, calcium silicate was more reliable. And in-service experience with mineral wool at a Canadian heavy crude refinery provided examples of many of the lab's findings. Lab tests, conducted under controlled conditions following industry accepted practices, showed calcium silicate insulation was stronger, tougher and more durable than the mineral wools to which it was compared. For instance, the calcium silicate insulation exhibited only some minor surface cracking when heated to 1,200[degrees]F (649[degrees]C), while the mineral wools suffered binder burnout resulting in sagging, delamination and a general loss of dimensional stability.

Nuclear Energy Research Initiative Annual Report-Innovative Approaches to Automating QA/QC of Fuel Particle Production Using On-Line Nondestructive Methods for Higher Reliability.  

Science Conference Proceedings (OSTI)

This document summarizes the activities performed and progress made in FY-03. Various approaches for automating the particle fuel production QC process using on-line nondestructive methods for higher reliability were evaluated. In this first-year of a three-year project, surrogate fuel particles made available for testing included leftovers from initial coater development runs. These particles had a high defect fraction and the particle properties spanned a wide range, providing the opportunity to examine worst-case conditions before refining the inspection methods to detect more subtle coating features. Particles specifically designed to evaluate the NDE methods being investigated under this project will be specified and fabricated at ORNL early next reporting period. The literature was reviewed for existing inspection technology and to identify many of the fuel particle conditions thought to degrade its performance. A modeling study, including the electromagnetic and techniques, showed that the in-line electromagnetic methods should provide measurable responses to missing layers, kernel diameter, and changes in coating layer thickness, with reasonable assumptions made for material conductivities. The modeling study for the ultrasonic methods provided the resonant frequencies that should be measured using the resonant ultrasound technique, and the results from these calculations were published in the proceedings for two conferences. The notion of a particle quality index to relate coating properties to fabrication process parameters was explored. Progress was made in understanding the fabrication process. GA identified key literature in this area and Saurwein (2003a) provided a literature review/summary. This literature has been reviewed. An approach previously applied to flexible manufacturing was adopted and the modification and development of the concepts to meet TRISO particle fuel manufacturing and QA/QC needs initiated. This approach establishes relationships between key process parameters and part parameters, including ''defects'' for each manufacturing step--which in this case is a coating layer. This activity will continue in year two, when an initial evaluation will be made using available process and particle data. Radiographic and Computed Tomography (CT) techniques were developed and refined to examine individual particles and batches of up to about 30 to 40 particles for kernel diameter, coating layer thickness and spatial uniformity. These results are essential for developing the defect library of characterized particles that will be used to calibrate the high-speed nondestructive measurement methods that are found capable of automatically detecting particles having properties outside a specified range. The in-line inspection methods evaluated include the electrical property measurement methods traditionally referred to as eddy current and capacitance (or dielectric) in the nondestructive test methods literature. An eddy current technique was developed and evaluated on stationary particles. Good correlation was found between the eddy current measurements and the radiographically determined particle dimensions. Initial measurements on fuel compacts using the eddy current approach showed that these materials are amenable to electrical inspection and that significant coil impedance variability can be observed among different samples.

Perfect NOT transformation and conjugate transformation  

E-Print Network (OSTI)

The perfect NOT transformation, probabilistic perfect NOT transformation and conjugate transformation are studied. Perfect NOT transformation criteria on a quantum state set $S$ of a qubit are obtained. Two necessary and sufficient conditions for realizing a perfect NOT transformation on $S$ are derived. When these conditions are not satisfied we discuss a probabilistic perfect NOT transformation (gate). We construct a probabilistic perfect NOT machine (gate) by a general unitary-reduction operation. With a postselection of the measurement outcomes, the probabilistic NOT gate yields perfectly complements of the input states. We prove that one can realize probabilistically the NOT gate of the input states secretly chosen from a certain set $S=\\{|\\Psi_1>, |\\Psi_2>,..., |\\Psi_n>\\}$ if and only if $|\\Psi_1>, |\\Psi_2>,...,$ and $|\\Psi_n>$ are linearly independent. We also generalize the probabilistic NOT transformation to the conjugate transformation in the multi-level quantum system. The lower bound of the best p...

Load Response Fundamentally Matches Power System Reliability Requirements  

Science Conference Proceedings (OSTI)

Responsive load is the most underutilized reliability resource available to the power system. Loads are frequently barred from providing the highest value and most critical reliability services; regulation and spinning reserve. Advances in communications and control technology now make it possible for some loads to provide both of these services. The limited storage incorporated in some loads better matches their response capabilities to the fast reliability-service markets than to the hourly energy markets. Responsive loads are frequently significantly faster and more accurate than generators, increasing power system reliability. Incorporating fast load response into microgrids further extends the reliability response capabilities that can be offered to the interconnected power system. The paper discusses the desired reliability responses, why this matches some loads' capabilities, what the advantages are for the power system, implications for communications and monitoring requirements, and how this resource can be exploited.

Spacetime transformation acoustics  

E-Print Network (OSTI)

A recently proposed analogue transformation method has allowed the extension of transformation acoustics to general spacetime transformations. We analyze here in detail the differences between this new analogue transformation acoustics (ATA) method and the standard one (STA). We show explicitly that STA is not suitable for transformations that mix space and time. ATA takes as starting point the acoustic equation for the velocity potential, instead of that for the pressure as in STA. This velocity-potential equation by itself already allows for some transformations mixing space and time, but not all of them. We explicitly obtain the entire set of transformations that do not leave its form invariant. It is in these cases that ATA shows its true potential, allowing for building a transformation acoustics method that enables the full range of spacetime transformations. We provide an example of an important transformation which cannot be achieved with STA. Using this transformation, we design and simulate an acous...

Reliability-based design optimization using efficient global reliability analysis.  

Science Conference Proceedings (OSTI)

Finding the optimal (lightest, least expensive, etc.) design for an engineered component that meets or exceeds a specified level of reliability is a problem of obvious interest across a wide spectrum of engineering fields. Various methods for this reliability-based design optimization problem have been proposed. Unfortunately, this problem is rarely solved in practice because, regardless of the method used, solving the problem is too expensive or the final solution is too inaccurate to ensure that the reliability constraint is actually satisfied. This is especially true for engineering applications involving expensive, implicit, and possibly nonlinear performance functions (such as large finite element models). The Efficient Global Reliability Analysis method was recently introduced to improve both the accuracy and efficiency of reliability analysis for this type of performance function. This paper explores how this new reliability analysis method can be used in a design optimization context to create a method of sufficient accuracy and efficiency to enable the use of reliability-based design optimization as a practical design tool.

The dielectric fluid used in the transformers biodegrades more rapidly and completely, and is non-bioaccumulating in aquatic species. Standardized tests show that five to six weeks is required for biodegradation. The thermal design increases the efficiency of heat removal and reduces thermal gradients in the winding; the transformer is 20% smaller and 25% lighter than conventional transformers.

A new Fourier method for evaluating generation system reliability indices  

SciTech Connect

A new, robust, and computationally efficient Fourier method for evaluating the loss of load probability and expected value of energy not served in a generation system is presented in this paper. An efficient algorithm is developed for computing the transformed probability density function of outages of all the generating units of the system. The fast Fourier transform algorithm is then used for transforming the load duration curve, and for inverse transformation of the product of the transformed outage function and the transformed load duration curve. As the method does not involve any approximation, it is expected to yield highly accurate results in all situations. Being a Fourier domain method, significant saving in computational effort results for systems with identical units. The application of the method is illustrated for a typical medium-sized system.

Amorphous Metal Transformer: Next Steps  

Science Conference Proceedings (OSTI)

Amorphous-metal transformers were developed through EPRI in the early 1980's. Over the next 15 years, US electric utilities bought and installed over 500,000 units and had satisfactory field experience. The demand for this product disappeared in North America late in the 1990's as deregulation set-in. Globally, this product has been in use, and its acceptance has been increasing. This paper describes the current state of amorphous transformer activities globally. An analysis using US Department of Energy...

Continuous Reliability Enhancement for Wind (CREW) database : wind plant reliability benchmark.  

SciTech Connect

To benchmark the current U.S. wind turbine fleet reliability performance and identify the major contributors to component-level failures and other downtime events, the Department of Energy funded the development of the Continuous Reliability Enhancement for Wind (CREW) database by Sandia National Laboratories. This report is the third annual Wind Plant Reliability Benchmark, to publically report on CREW findings for the wind industry. The CREW database uses both high resolution Supervisory Control and Data Acquisition (SCADA) data from operating plants and Strategic Power Systems' ORAPWind%C2%AE (Operational Reliability Analysis Program for Wind) data, which consist of downtime and reserve event records and daily summaries of various time categories for each turbine. Together, these data are used as inputs into CREW's reliability modeling. The results presented here include: the primary CREW Benchmark statistics (operational availability, utilization, capacity factor, mean time between events, and mean downtime); time accounting from an availability perspective; time accounting in terms of the combination of wind speed and generation levels; power curve analysis; and top system and component contributors to unavailability.

On discrete cosine transform  

E-Print Network (OSTI)

The discrete cosine transform (DCT), introduced by Ahmed, Natarajan and Rao, has been used in many applications of digital signal processing, data compression and information hiding. There are four types of the discrete cosine transform. In simulating the discrete cosine transform, we propose a generalized discrete cosine transform with three parameters, and prove its orthogonality for some new cases. A new type of discrete cosine transform is proposed and its orthogonality is proved. Finally, we propose a generalized discrete W transform with three parameters, and prove its orthogonality for some new cases.

Constraint condition on transformed relation for generalized acoustics  

E-Print Network (OSTI)

Contrary to transformation optics (TO), there exist many possibilities for transformed relations of material property and field variable in case of transformation acoustics (TA). To investigate the underlining mechanism and develop a general method that can obtain the full transformed relations, an alternative interpretation to the form-invariance is explored. We consider a spatial transformation, with which a physical phenomenon described in an initial space is transformed to a deformed space, and interpret the mapping by local affine transformation point-by-point. Further, we postulate that the transformed material property and field must rebuild the same physical process, and that the energy must be conserved at each point during the transformation. These conditions impose the constraint on the transformed relation for material property and field. By establishing two local Cartesian frames defined uniquely by the spatial transformation, any physical quantity is shown to first experience a rigid rotation and then a stretch operation during the transformation. We show that the constraint conditions are not enough to determine completely the transformed relation for TA, leaving a possibility to define them differently as found in the literature. New acoustic transformations with constant density or modulus are also proposed and verified by constructing a two-dimensional acoustic cloak. Finally, we show that the transformed relation is uniquely determined for transformation optics, and discuss how this method can be extended to other transformation physics.

DAKOTA reliability methods applied to RAVEN/RELAP-7.  

SciTech Connect

This report summarizes the result of a NEAMS project focused on the use of reliability methods within the RAVEN and RELAP-7 software framework for assessing failure probabilities as part of probabilistic risk assessment for nuclear power plants. RAVEN is a software tool under development at the Idaho National Laboratory that acts as the control logic driver and post-processing tool for the newly developed Thermal-Hydraulic code RELAP-7. Dakota is a software tool developed at Sandia National Laboratories containing optimization, sensitivity analysis, and uncertainty quantification algorithms. Reliability methods are algorithms which transform the uncertainty problem to an optimization problem to solve for the failure probability, given uncertainty on problem inputs and a failure threshold on an output response. The goal of this work is to demonstrate the use of reliability methods in Dakota with RAVEN/RELAP-7. These capabilities are demonstrated on a demonstration of a Station Blackout analysis of a simplified Pressurized Water Reactor (PWR).

High-reliability computing for the smarter planet  

SciTech Connect

The geometric rate of improvement of transistor size and integrated circuit performance, known as Moore's Law, has been an engine of growth for our economy, enabling new products and services, creating new value and wealth, increasing safety, and removing menial tasks from our daily lives. Affordable, highly integrated components have enabled both life-saving technologies and rich entertainment applications. Anti-lock brakes, insulin monitors, and GPS-enabled emergency response systems save lives. Cell phones, internet appliances, virtual worlds, realistic video games, and mp3 players enrich our lives and connect us together. Over the past 40 years of silicon scaling, the increasing capabilities of inexpensive computation have transformed our society through automation and ubiquitous communications. In this paper, we will present the concept of the smarter planet, how reliability failures affect current systems, and methods that can be used to increase the reliable adoption of new automation in the future. We will illustrate these issues using a number of different electronic devices in a couple of different scenarios. Recently IBM has been presenting the idea of a 'smarter planet.' In smarter planet documents, IBM discusses increased computer automation of roadways, banking, healthcare, and infrastructure, as automation could create more efficient systems. A necessary component of the smarter planet concept is to ensure that these new systems have very high reliability. Even extremely rare reliability problems can easily escalate to problematic scenarios when implemented at very large scales. For life-critical systems, such as automobiles, infrastructure, medical implantables, and avionic systems, unmitigated failures could be dangerous. As more automation moves into these types of critical systems, reliability failures will need to be managed. As computer automation continues to increase in our society, the need for greater radiation reliability is necessary. Already critical infrastructure is failing too frequently. In this paper, we will introduce the Cross-Layer Reliability concept for designing more reliable computer systems.

Fatigue case study and reliability analyses for wind turbines  

DOE Green Energy (OSTI)

Modern wind turbines are fatigue critical machines used to produce electrical power. To insure long term, reliable operation, their structure must be optimized if they are to be economically viable. The fatigue and reliability projects in Sandia`s Wind Energy Program are developing the analysis tools required to accomplish these design requirements. The first section of the paper formulates the fatigue analysis of a wind turbine using a cumulative damage technique. The second section uses reliability analysis for quantifying the uncertainties and the inherent randomness associated with turbine performance and the prediction of service lifetimes. Both research areas are highlighted with typical results.

Optimization of distribution transformer efficiency characteristics. Final report, March 1979  

SciTech Connect

A method for distribution transformer loss evaluation was derived. The total levalized annual cost method was used and was extended to account properly for conditions of energy cost inflation, peak load growth, and transformer changeout during the evaluation period. The loss costs included were the no-load and load power losses, no-load and load reactive losses, and the energy cost of regulation. The demand and energy components of loss costs were treated separately to account correctly for the diversity of load losses and energy cost inflation. The complete distribution transformer loss evaluation equation is shown, with the nomenclature and definitions for the parameters provided. Tasks described are entitled: Establish Loss Evaluation Techniques; Compile System Cost Parameters; Compile Load Parameters and Loading Policies; Develop Transformer Cost/Performance Relationship; Define Characteristics of Multiple Efficiency Transformer Package; Minimize Life Cycle Cost Based on Single Efficiency Characteristic Transformer Design; Minimize Life Cycle Cost Based on Multiple Efficiency Characteristic Transformer Design; and Interpretation.
