Chapter 21 - Hydroelectric Power  

Science Journals Connector (OSTI)

Hydroelectric power (hydropower) is a renewable energy source where electrical power is derived from the energy of water moving from higher to lower elevations. It is a proven, mature, predictable and price competitive technology. Hydropower has the best conversion efficiencies among all known energy sources (about 90% efficiency, water to wire). It requires relatively high initial investment, but has a long lifespan with very low operation and maintenance costs. The existing hydropower system has an annual generation capacity of 3500TWha?1 and contributes to 16% of the annual electricity generation worldwide. There is still a large potential for further development, as the total technical potential has been estimated to be roughly 15000TWh. Out of this, about 8000TWh has been classified as economical potential. In Europe close to 50% of technical potential has already been developed, in Asia 25% and in Africa only 8%. Significant potential can also be found in existing infrastructure that currently lacks generating units (e.g. existing barrages, weirs, dams, canal fall structures, water supply schemes) by adding new hydropower facilities. Only 25% of the existing 45000 large dams in the world are currently used for hydropower, the other 75% are used exclusively for other purposes (e.g. irrigation, flood control, navigation and urban water supply schemes). Hydropower offers significant potential for carbon emissions reductions, since greenhouse gas (GHG) emissions are generally very low, typically less than 1% of that from coal power plants. Hydropower is cost competitive, with levelised cost of energy (LCOE) typically in the range (3 to 5) USc(kWh)?1, which is comparable to the cost of energy from thermal power plants. Hydropower has an energy payback ratio (EPR) of 200300, highest of all types of renewable energies. Hydropower can provide both energy and water management services and also help to support other variable renewable energy sources like wind and solar, by providing storage and load balancing services.

Solar Power(SSP) Solar Power(SSP) Jump to: navigation, search Space Solar Power (SSP) is the name commonly given to the concept of deploying a system of satellites and ground receivers that would collect the sun's energy at GeoSynchronous Earth Orbit (GEO is an orbit 35,000 km above the Earth's equator) [1] and beam that energy, via wireless power transmission (WPT) to Earth for use. Many names have been given to such satellites and systems since Peter Glaser first invented the concept in 1968: Solar Power Satellites (SPS), Satellite Solar Power Systems (SSPS), Space-Based Solar Power (SBSP), Power Satellites, Sunsats, etc., The numerous existing communication satellites (comsats) differ from the envisioned SSP Satellites, or sunsats, in that sunsats would optimize for

High-efficiency solar dynamic space power generation system  

SciTech Connect (OSTI)

Space power technologies have undergone significant advances over the past few years, and great emphasis is being placed on the development of dynamic power systems at this time. A design study has been conducted to evaluate the applicability of a combined cycle concept-closed Brayton cycle and organic Rankine cycle coupling-for solar dynamic space power generation systems. In the concept presented in this paper (solar dynamic combined cycle), the waste heat rejected by the closed Brayton cycle working fluid is utilized to heat the organic working fluid of an organic Rankine cycle system. This allows the solar dynamic combined cycle efficiency to be increased compared to the efficiencies of two subsystems (closed Brayton cycle and organic fluid cycle). Also, for small-size space power systems (up to 50 kW), the efficiency of the solar dynamic combined cycle can be comparable with Stirling engine performance. The closed Brayton cycle and organic Rankine cycle designs are based on a great deal of maturity assessed in much previous work on terrestrial and solar dynamic power systems. This is not yet true for the Stirling cycles. The purpose of this paper is to analyze the performance of the new space power generation system (solar dynamic combined cycle). The significant benefits of the solar dynamic combined cycle concept such as efficiency increase, mass reduction, specific area-collector and radiator-reduction, are presented and discussed for a low earth orbit space station application.

Integrated solar upper stage (ISUS) space demonstration design  

Science Journals Connector (OSTI)

High temperature solar thermal propulsion/power systems will enable the placement of higher power satellite systems launched from smaller less expensive launch vehicles. The on-going Integrated Solar Upper Stage (ISUS) Program sponsored by Phillips Laboratory is one such solar thermal system. A system test of an engine ground test configuration of ISUS is planned for Spring 1997. The next step in the development of the ISUS system will be a flight demonstration mission. This paper details the conceptual designs for two potential ISUS space demonstration configurations. These designs were developed with a design-to-cost philosophy for a LEO (low Earth orbit) to GEO (geosynchronous equatorial orbit) and LEO to HEEO (highly elliptical Earth orbit) flight demonstration missions. Design considerations included packaging within the selected launch vehicle fairings (Pegasus XL and SSLV Taurus) system performance propellant selection ( H 2 CH 4 or NH 3 ) and 100150 watts of power production using thermionic diodes.

Recently the Air Force has been investigating the feasibility of developing a thermionic generator heated with a large inflatable solar concentrator for orbital space power missions with electrical power requirements that exceed 50 kWe. This concept analysis follows a similar study by the NASA Jet Propulsion Laboratory in the 1960s where the objective was a 500 We power generator for interplanetary probes. Details of the potential missions system designs and power specifications as well as results of ground tests and demonstrations are detailed and compared for each era.

Underground pumped hydroelectric storage  

SciTech Connect (OSTI)

Underground pumped hydroelectric energy storage was conceived as a modification of surface pumped storage to eliminate dependence upon fortuitous topography, provide higher hydraulic heads, and reduce environmental concerns. A UPHS plant offers substantial savings in investment cost over coal-fired cycling plants and savings in system production costs over gas turbines. Potential location near load centers lowers transmission costs and line losses. Environmental impact is less than that for a coal-fired cycling plant. The inherent benefits include those of all pumped storage (i.e., rapid load response, emergency capacity, improvement in efficiency as pumps improve, and capacity for voltage regulation). A UPHS plant would be powered by either a coal-fired or nuclear baseload plant. The economic capacity of a UPHS plant would be in the range of 1000 to 3000 MW. This storage level is compatible with the load-leveling requirements of a greater metropolitan area with population of 1 million or more. The technical feasibility of UPHS depends upon excavation of a subterranean powerhouse cavern and reservoir caverns within a competent, impervious rock formation, and upon selection of reliable and efficient turbomachinery - pump-turbines and motor-generators - all remotely operable.

Automation of hydroelectric power plants  

SciTech Connect (OSTI)

This paper describes how the author's company has been automating its hydroelectric generating plants. The early automations were achieved with a relay-type supervisory control system, relay logic, dc tachometer, and a pneumatic gate-position controller. While this system allowed the units to be started and stopped from a remote location, they were operated at an output that was preset by the pneumatic control at the generating site. The supervisory control system at the site provided such information as unit status, generator breaker status, and a binary coded decimal (BCD) value of the pond level. The generating units are started by energizing an on-site relay that sets the pneumatic gate controller to a preset value above the synchronous speed of the hydroelectric generator. The pneumatic controller then opens the water-wheel wicket gates to the preset startup position. As the hydroelectric generator starts to turn, the machine-mounted dc tachometer produces a voltage. At a dc voltage equivalent to synchronous speed, the generator main breaker closes, and a contact from the main breaker starts a field-delay timer. Within a few seconds, the field breaker closes. Once the cycle is complete, a relay changes the pneumatic setpoint to a preset operating point of about 8/10 wicket gate opening.

SciTech Connect (OSTI)

1-MeV electron irradiation effects on MBE-grown InGaAs and AlGaAs solar cells have been examined in comparison with previous results for radiation damage of InP and GaAs solar cells in order to clarify radiation-resistance of advanced space solar cells. Moreover, 1-MeV electron irradiation results of several space solar cells such as InP, InGaP, InGaAsP, GaAs, AlGaAs, InGaAs, Si, Ge, and CuInSe{sub 2} cells have also been analyzed by considering their damage constants, bandgap energies and optical absorption coefficients. The authors believe that this study will provide a unified model for radiation-resistance of advanced space solar cells.

Toward space solar power: Wireless energy transmission experiments past, present and future  

Science Journals Connector (OSTI)

Solar power is a reality. Today increasing numbers of photovoltaic and other solar-powered installations are in service around the world and in space. These uses range from the primary electric power source for satellites remote site scientific experiments and villages in developing countries to augmenting the commercial electric grid and providing partial power for individual businesses and homeowners in developed countries. In space electricity generated by photovoltaic conversion of solar energy is the mainstay of power for low Earth and geostationary satellite constellations. Still for all its acceptance as a benign and environmentally friendly energy source terrestrial solar power has yet to be seriously considered a viable technology for providing base electrical generating capacity. The obvious reason is sunshine on Earth is too unreliable. In addition to the diurnal and seasonal cycles inclement weather reduces the average daily period and intensity of insolation. However the Sun shines constantly in space. The challenge is to harvest and transmit the energy from space to Earth. The concept of space solar power based on microwave wireless energy transmission was first put forth more than 25 years ago by Dr. Peter Glaser. We review historical experiments in wireless energy transmission which have brought the technology from a laboratory curiosity to its present status. Results from recent experiments and their implications for wireless energy transmission as an enabling technology for space solar power are reviewed. Current developments are discussed along with proposed terrestrial and space experiments.

Solar abundances and helioseismology: fine structure spacings and separation ratios of low-degree p modes  

E-Print Network [OSTI]

We have used 4752 days of data collected by the Birmingham Solar-Oscillations Network (BiSON) to determine very precise oscillation frequencies of acoustic low-degree modes that probe the solar core. We compare the fine (small frequency) spacings and frequency separation ratios formed from these data with those of different solar models. We find that models constructed with low metallicity are incompatible with the observations. The results provide strong support for lowering the theoretical uncertainties on the neutrino fluxes. These uncertainties had recently been raised due to the controversy over the solar abundances.

Fish and hydroelectricity; Engineering a better coexistence  

SciTech Connect (OSTI)

This paper reports on the problems that hydroelectric plants have regarding fish populations. The utilities that operate these plants are finding that accommodating migrating fish presents unique engineering challenges, not the least of which involves designing and building systems to protect fish species whose migratory behavior remains something of a mystery. Where such systems cannot be built, the status of hydroelectric dams may be in doubt, as is now the case with several dams in the United States. A further twist in some regions in the possibility that certain migratory fish will be declared threatened or endangered-a development that could wreak havoc on the hydroelectric energy supply in those regions.

Design Space Exploration of a 5 \\{MWth\\} Small Particle Solar Receiver  

Science Journals Connector (OSTI)

Abstract We present a design space exploration of a 5 \\{MWth\\} Small Particle Solar Receiver for solar tower power plants. This new solar receiver, developed under the support of the U.S. Department of Energy's SunShot Program, aims to volumetrically absorb concentrated solar irradiation using an air-particle mixture to drive a gas turbine or a combined cycle at much higher temperature than the state-of-the-art molten salt receivers. Among other advantages, the thermodynamic efficiency of the power block and the overall efficiency of the plant would considerably increase with this technology. The design space consists of the wall angle of the receiver, the geometry of the window (necessary to allow the solar irradiation to enter into the receiver) and the radiative properties of the walls. The constraints are based on material limits, ensuring the mechanical integrity of the quartz window, and other technical issues; though some of them are imposed via a penalty method. The design space is explored through parametric studies and a multidisciplinary approach is adopted. The aluminum oxide walls, the 45 spherical-cap window and the 45 wall- angle receiver are preferred due to their best compromise between thermal efficiency and wall temperature.

On the effects of solar storms to the decaying orbital space debris  

SciTech Connect (OSTI)

Any man-made object in Earth's orbit that no longer serves a useful purpose is classified as orbital debris. Debris objects come from a variety of sources. The majority is related to satellite fragmentation. Other major sources of debris are propulsion systems, and fragmentation of spent upper stages, payload and mission related debris. Serious concern about orbital debris has been growing. Knowledge of the future debris environment is important to both satellite designers, and mission planners, who need to know what hazards a satellite might encounter during the course of its mission. Therefore, it is important to know how much debris is in orbit, where it is located, and when it will decay. The debris environment is complex and dynamically evolving. Objects of different shape and size behave differently in orbit. The geoeffectiveness space environments include solar flux at 10.7 cm, solar energetic particles flux or speed, solar wind flow pressure, electric field, and geomagnetic indices. We study the decaying orbital debris from Tracking and Impact Prediction (TIP) messages in conjuction with geoeffectiveness space environments through time epoch correlation. We found that the decaying and reentry orbital debris are triggered by space environment enhancement within at least one week before reentry. It is not necessary a transient or high energetic and severe solar storm events are needed in decaying processes. We propose that the gradual enhancement processes of space environment will cause satellite surface charging due to energetic electron and enhance drag force.

LHC: the emptiest space in the solar system  

Science Journals Connector (OSTI)

Proton beams have been colliding at 7TeV in the Large Hadron Collider(LHC) since 30 March 2010, meaning that the LHC research programme is underway. Particle physicists around the world are looking forward to using the data from these collisions, as the LHC is running at an energy three and a half times higher than previously achieved at any particle accelerator. There are some important questions to be answered by the LHC experiments. What is the origin of mass? What is 96% of the universe made of? Why is there no more antimatter? To avoid colliding with gas molecules inside the accelerator, the beams of particles travel in an ultra-high vacuuma cavity as empty as interplanetary space. The internal pressure of the LHC is 10 ? 9Pa, one hundred times less than the pressure on the Moon! The aim of this article is to introduce a few simple physical calculations about some physics phenomena related to pressure that take place in the LHC, so that they can be directly used in the secondary school classroom and stimulate the students' interest in the greatest experiment in history.

Chemically strengthened protection glasses for the applications of space solar cells  

SciTech Connect (OSTI)

The effects of chemically strengthened processing and the ion beam irradiation on the mechanical characteristics of space solar cell protection glasses are investigated using dynamic mechanical analysis and micro hardness instrument; also the corresponding optical properties were analyzed by utilizing the UV/visible spectrophotometer. The results suggest that the flexural strength, fracture toughness and surface characteristics are enhanced via the chemical strengthening process. Importantly, such process has a trivial influence with ?0.2% degradation on the transparency of chemically strengthened glasses in the band range of 350 ? 1000 nm, while exhibits an excellent resistance on radiation damage by ion beams bombardment, demonstrating an outstanding durability in the space radiation environment.

Exploitation of temporary water flow by hybrid PV-hydroelectric plant  

Science Journals Connector (OSTI)

The paper presents a new type of Renewable Energy Sources (RES) suitable for exploitation watercourse with periodical-temporary water flow. This innovative solution consist of Hydroelectric Plant (HEP) and solar Photovoltaic (PV) generator working together as one hybrid power plant, producing green energy with the same characteristics as classical hydroelectric plants. The main objective of this hybrid solution is achievement of optimal renewable energy production in order to increase the share of RES in an Electricity Power System (EPS). As a paradigm of such exploitation of RES, the example of HEP Zavrelje/Dubrovnik in Croatia was used, where it was ascertained that the proposed solution of hybrid PV-HEP system is natural, realistic and very acceptable, which enhances the characteristics of both energy sources. The application of such hybrid systems would increase the share of high quality RES in energy systems.

Analysis of a solar assisted heat pump system for indoor swimming pool water and space heating  

Science Journals Connector (OSTI)

Solar energy application is a good alternative to replace primary energy source especially for large-scale installations. Heat pumps are also effective means to reduce primary energy consumption. This paper describes a case study with a new design of solar assisted heat pump (SAHP) for indoor swimming pool space- and water-heating purposes. The system design procedure was first presented. The entire system was then modeled via the TRNSYS simulation environment and the energy performance was evaluated based on the winter time operation schedule. Economic analysis with a range of collector areas was also performed. The simulation results show that the overall system COP can reach 4.5, and the fractional factor of energy saving is 79% as compared to the conventional energy system. The economical payback period is less than 5years.

Towards Space Solar Power - Examining Atmospheric Interactions of Power Beams with the HAARP Facility  

E-Print Network [OSTI]

In the most common space solar power (SSP) system architectures, solar energy harvested by large satellites in geostationary orbit is transmitted to Earth via microwave radiation. Currently, only limited information about the interactions of microwave beams with energy densities of several tens to hundreds of W/m$^2$ with the different layers of the atmosphere is available. Governmental bodies will likely require detailed investigations of safety and atmospheric effects of microwave power beams before issuing launch licenses for SSP satellite systems. This paper proposes to collect representative and comprehensive data of the interaction of power beams with the atmosphere by extending the infrastructure of the High Frequency Active Auroral Research Program (HAARP) facility in Alaska, USA. Estimates of the transmission infrastructure performance as well as measurement devices and scientific capabilities of possible upgrade scenarios will be discussed. The proposed upgrade of the HAARP facility is expected to d...

Radioisotope electric propulsion of sciencecraft to the outer solar system and near-interstellar space  

SciTech Connect (OSTI)

Recent results are presented in the study of radioisotope electric propulsion as a near-term technology for sending small robotic sciencecraft to the outer Solar System and near-interstellar space. Radioisotope electric propulsion (REP) systems are low-thrust, ion propulsion units based on radioisotope electric generators and ion thrusters. Powerplant specific masses are expected to be in the range of 100 to 200 kg/kW of thrust power. Planetary rendezvous missions to Pluto, fast missions to the heliopause (100 AU) with the capability to decelerate an orbiter for an extended science program and prestellar missions to the first gravitational lens focus of the Sun (550 AU) are investigated.

Natural Transfer of Viable Microbes in Space from Planets in the Extra-Solar Systems to a Planet in our Solar System and Vice-Versa  

E-Print Network [OSTI]

We investigate whether it is possible that viable microbes could have been transported to Earth from the planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comet or asteroid impacts on such planets. The probabilities of close encounters with other solar systems are taken into account as well as the limitations of bacterial survival times inside ejecta in space, caused by radiation and DNA decay. The conclusion is that no potentially DNA/RNA life-carrying ejecta from another solar system in the general Galactic star field landed on Earth before life already existed on Earth, not even if microbial survival time in space is as long as tens of millions of years. However, if the Sun formed initially as a part of a star cluster, as is commonly assumed, we cannot rule out the possibility of transfer of life from one of the sister systems to us. Likewise, there is a possibility that some extra-solar planets carry life that originated in our solar system. It will be of great interest to identify the members of the Sun's birth cluster of stars and study them for evidence for planets and life on the planets. The former step may be accomplished by the GAIA mission, the latter step by the SIM and DARWIN missions. Therefore it may not be too long until we have experimental knowledge on the question whether the natural transfer of life from one solar system to another has actually taken place.

Forced response analysis of hydroelectric systems  

Science Journals Connector (OSTI)

At off-design operating points, Francis turbines develop cavitation vortex rope in the draft tube which may interact with the hydraulic system. Risk resonance assessment by means of eigenmodes computation of the system is usually performed. However, the system response to the excitation source induced by the cavitation vortex rope is not predicted in terms of amplitudes and phase. Only eigenmodes shapes with related frequencies and dampings can be predicted. Besides this modal analysis, the risk resonance assessment can be completed by a forced response analysis. This method allows identifying the contribution of each eigenmode into the system response which depends on the system boundary conditions and the excitation source location. In this paper, a forced response analysis of a Francis turbine hydroelectric power plant including hydraulic system, rotating train, electrical system and control devices is performed. First, the general methodology of the forced response analysis is presented and validated with time domain simulations. Then, analysis of electrical, hydraulic and hydroelectric systems are performed and compared to analyse the influence of control structures on pressure fluctuations induced by cavitation vortex rope.

The field test and optimization of a solar assisted heat pump system for space heating in extremely cold area  

Science Journals Connector (OSTI)

Abstract As a kind of sustainable energy source, solar energy is becoming highly valued. Especially in extremely cold areas, the amount of energy consumed for space heating is huge, and the conventional coal heating has polluted the environment seriously, therefore solar heating is significant on both energy and environment conservation. In this study, a solar assisted heat pump (SAHP) system was investigated for space heating under extremely cold climatic condition. The system principle and operation modes was presented, and then the project profile and design procedure were introduced, and finally the system performance was evaluated by field test on typical winter days and modeling via TRNSYS simulation environment. The results show that the solar collector efficiency was 51%, and the solar fraction can reach 66% in December. Economic analysis was also performed and the heating expenses for the present SAHP system was 18RMB/m2. Finally, the temperatures of solar energy for both direct heating and storage and only for direct heating (T1A and T1B) were simulated and optimized, which have important significance on the operation time of different operation modes.

Solar Photovoltaic and Solar Thermal Electric Technologies Solar Photovoltaic and Solar Thermal Electric Technologies International Energy Outlook 2009 Solar Photovoltaic and Solar Thermal Electric Technologies Solar power is one of the fastest-growing sources of renewable energy worldwide. Many nations, concerned about the environmental impacts of electricity generation from fossil fuels or from large-scale hydroelectric plants, have been turning to solar power as an environmentally benign alternative. The solar energy that reaches the earth can be harnessed to generate electric power, and the potential for large-scale applications of solar power has improved markedly in recent years. Two solar power technologies—solar photovoltaic and solar thermal—are widely employed today, and their use is likely to increase in the future.

Health and environmental impacts of the hydroelectric fuel cycle  

Science Journals Connector (OSTI)

The impacts on health and the environment and the associated damage costs caused by the hydroelectric fuel cycle are assessed in this paper. To this purpose, a large hydroelectric project along the Nestos river in northern Greece has been selected as an example. A large number of impacts have been identified. Occupational accidents, impacts on agriculture and forests, noise produced during the operation of the plant, impacts on biodiversity due to the physical presence of the dams, and alterations to the local water balance are the most important of them. The results of the analysis show that the major contributors to the damage cost of the hydroelectric fuel cycle are impacts on biodiversity and fatal occupational accidents, especially those that occur during the construction phase of the project. Nonetheless hydroelectricity is an environmentally-friendly energy source that exhibits lower damage values compared to other electricity generating technologies.

Cost assessment of efficiency losses in hydroelectric plants  

Science Journals Connector (OSTI)

Some important real-time tasks of the independent system operator (ISO) are the monitoring and control of power system events (load deviations and contingencies). These events are usually managed by the ISO using operating reserve ancillary services. These services represent an additional capacity (MW) available in generators and some interruptible loads. Generators must change their operating points in order that this capacity can remain available. These changes might lead to efficiency losses in energy production. In systems with a high percentage of hydroelectric production, hydroelectric plants need to know the impact of ancillary services on their profits. This work therefore analyzes the cost of efficiency losses due to operating reserve availability in hydroelectric generators. A method to calculate this cost component is proposed using a unit commitment dispatch for a single hydroelectric plant. This dispatch is performed without considering the operating reserve availability and is compared with the traditional dispatch, which takes into account the availability of operating reserve. The proposal is used to calculate the cost of efficiency losses on a Brazilian hydroelectric generator. We found that the cost of efficiency losses can be considerable when compared to the incomes of a hydroelectric plant in the short-term market.

Hoopa Valley Small Scale Hydroelectric Feasibility Project  

SciTech Connect (OSTI)

This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

Progress and future view of silicon space solar cells in Japan  

SciTech Connect (OSTI)

The progress and the future of silicon (Si) space solar cells in Japan are reviewed. In 1994, two types of the high-efficiency silicon (HES) cells were developed: (1) NRS/LBSF cell; (2) NRS/BSF cell. The former shows the conversion efficiency of 18.0% (AM0, 28 C) at beginning-of-life (BOL), the latter shows superior radiation tolerance. In 1998, the radiation tolerance of the NRS/BSF cell was improved; moreover, the advanced high-efficiency silicon-1 (AHES-1) cell was accomplished. It shows 13.1% at end-of-life (EOL). The development has been proceeded to make the 13.7% EOL cell: AHES-2 cell. In 1994, the integrated bypass function (IBF), which prevents failures due to reverse biasing of cells, was proposed. The NRS/BSF cells with IBF have been used already on several satellites. The structures, performance, and radiation tolerances of these cells are introduced. New approaches for further improvement are proposed in the future view.

Short-term solar irradiance forecasting using exponential smoothing state space model  

Science Journals Connector (OSTI)

Abstract We forecast high-resolution solar irradiance time series using an exponential smoothing state space (ESSS) model. To stationarize the irradiance data before applying linear time series models, we propose a novel Fourier trend model and compare the performance with other popular trend models using residual analysis and the Kwiatkowski-Phillips-Schmidt-Shin (KPSS) stationarity test. Using the optimized Fourier trend, an ESSS model is implemented to forecast the stationary residual series of datasets from Singapore and Colorado, USA. To compare the performance with other time series models, autoregressive integrated moving average (ARIMA), linear exponential smoothing (LES), simple exponential smoothing (SES) and random walk (RW) models are tested using the same data. The simulation results show that the ESSS model has generally better performance than other time series forecasting models. To assess the reliability of the forecasting model in real-time applications, a complementary study of the forecasting 95% confidence interval and forecasting horizon of the ESSS model has been conducted.

Current issues in terrestrial solar radiation instrumentation for energy, climate, and space applications  

Science Journals Connector (OSTI)

Uncertainty in terrestrial solar radiation measurements of a few watts per square metre (1 W/m2 to 2 W/m2) is needed to validate estimates of the Earth's radiation balance derived from satellite data. The characterization of solar energy resources for renewable energy technologies requires similar accuracy for economical technology deployment. Solar radiation measurement research at the National Renewable Energy Laboratory addresses calibrations, operational characteristics, and corrections for terrestrial solar radiation measurements. The characterization of field instrument geometric and thermal responses contributing to radiometric errors is described, together with correction schemes reducing the uncertainty of broadband irradiance measurements from tens of watts per square metre to a few (2 W/m2 to 5 W/m2). Such improvements in accuracy reduce the time and labour required for detecting and quantifying trends in terrestrial solar radiation and possible changes in the Earth's radiation budget.

A Study of United States Hydroelectric Plant Ownership  

SciTech Connect (OSTI)

Ownership of United States hydroelectric plants is reviewed from several perspectives. Plant owners are grouped into six owner classes as defined by the Federal Energy Regulatory Commission. The numbers of plants and the corresponding total capacity associated with each owner class are enumerated. The plant owner population is also evaluated based on the number of owners in each owner class, the number of plants owned by a single owner, and the size of plants based on capacity ranges associated with each owner class. Plant numbers and corresponding total capacity associated with owner classes in each state are evaluated. Ownership by federal agencies in terms of the number of plants owned by each agency and the corresponding total capacity is enumerated. A GIS application that is publicly available on the Internet that displays hydroelectric plants on maps and provides basic information about them is described.

The renewable energy share of total world energy consumption is expected to continue at a level of about 8 percent from 1997 through 2020, despite a projected 54-percent increase in consumption of hydroelectricity and other renewable resources. The renewable energy share of total world energy consumption is expected to continue at a level of about 8 percent from 1997 through 2020, despite a projected 54-percent increase in consumption of hydroelectricity and other renewable resources. The development of renewable energy sources is constrained in the International Energy Outlook 2000 (IEO2000) reference case projections by expectations that fossil fuel prices will remain low and, as a result, renewables will have a difficult time competing. Although energy prices rebounded in 1999 from 1998 lows, it remains unlikely that renewable energy can compete economically over the projection period.

Karnataka power sector: a case for hydroelectric power  

Science Journals Connector (OSTI)

Karnataka, a southern state in India, flanked by the rich tropical forests of the Western Ghats, has a large potential for hydroelectric power, only a third of which has been harnessed so far. Only about two decades back, this state had surplus power/energy. The state has of late been going through an acute power crisis due to the unplanned growth of industry, unmetered energy supply to the agricultural sector, large losses in transmission, distribution and inefficient utilisation of electrical energy. Stalling of some hydroelectric projects on environmental issue and delaying the completion of some due to shortage of funds have aggravated the crisis. Coal-based thermal generators are already providing 630 MW of power and more are to be installed soon. A 470 MW nuclear generating station is about to be completed. While this drive for increasing power generation is on, the sustainability of this effort from the economic and environmental view point is being seriously questioned. An alternative end-use-oriented approach to energy planning has been proposed which is described as an 'environmentally sound development pathway'. It seems unlikely, however, that this path will be followed to its end, not at least in the near future. A prudent combination of: (a) hydroelectric power generation, large and small, (b) energy conservation and end-use-oriented energy utilisation to the extent feasible, may be the most economically and environmentally suitable option for some time to come - particularly for Karnataka State.

Technology of Computational Fluid Dynamics in space engines and solar-gravity draught power plants  

Science Journals Connector (OSTI)

Non-isentropic discontinuous, unsteady flows with energy addition or extraction, during ignition of solid propellant rocket motors or tall solar towers heating transients are approached through a wave front method, initially developed by Zannetti for isentropic flows in aerodynamics. Its application in discontinuous flows with zones of different behaviour and energy extraction proves highly efficient. Computational efficiency is demonstrated by Computational Fluid Dynamics simulation of the starting transients in ADDA Solid Rocket Engines (SRE) and in the SEATTLER solar mirror tower. The code is exclusively directed to unsteady flow simulations in slender channels. The wave front model scheme covers the dual behaviour of fully non-isentropic flow with mass addition and mixing in the thrust chamber or blunt heat addition in a heater and fully isentropic through the exhaust nozzle or gravity draught in a tall tower. Along the tower of the solar-gravity draught power plants, small perturbation discontinuous flows are covered. Code robustness is demonstrated during runs on the PC. The 1D numerical scheme is based on the resolution of gasdynamic discontinuities within the enhanced method of Zannetti.

International Energy Outlook 1999 - Hydroelectricity and Other Renewable  

Gasoline and Diesel Fuel Update (EIA)

hydroelectricty.gif (7905 bytes) hydroelectricty.gif (7905 bytes) Renewable energy use is projected to increase by 62 percent between 1996 and 2020. Almost half the increase is expected in the developing world, where large-scale hydroelectric projects still are being undertaken. Low prices for oil and natural gas in world energy markets continued to diminish the potential for rapid development of renewable energy sources worldwide. Oil prices hit 20-year lows in 1998, in part because the Asian economic crisis resulted in lower worldwide demand. Even production cut agreements by some major oil producers, such as Saudi Arabia, Mexico, and Venezuela, failed to provide measurable price recovery during 1998. On the positive side, the Kyoto Climate Change Protocol proposals to cut greenhouse gas emissions levels may provide an opportunity for growth in

On the Fatigue Reliability of Hydroelectric Francis Runners  

Science Journals Connector (OSTI)

Abstract The reliability assessment of large rotating structures like hydroelectric Francis runners is often limited by our capacity to define a proper limit state combined with a relevant degradation model. In this paper, we propose that the proper limit state for fatigue reliability of such structures is the onset of high cycle fatigue (HCF). Based on this premise, a prior interval for our limit state based on available literature is presented. The prior assumptions are believed to be the first step toward validation of the applicability and suitability of the proposed model. The paper includes an overview of the theoretical background for reliability assessment of Francis turbine runners, the methodology used, and the results obtained from the information gathered from the available literature.

Optimization of Technical Diagnostics Procedures for Hydroelectric Power Plants  

Science Journals Connector (OSTI)

In this paper, a mathematical model is proposed for determination of the optimal solution for the maintenance system of a specific steel structure the hydraulic power plant. The aim is to obtain the maximum efficiency of the plant within existing conditions and limitations. The objective of a mathematical model is to select the diagnostics parameters, which define knowledge of the permissible reliability level and certain analytic expression, which corresponds to precisely described state of hydroelectric power plant components assembly. Model of technical diagnostics procedures optimization represents a specific approach to problems of preventive maintaining according to state. It is related to the concept of state parameters change, which represents a basis for obtaining the optimal solution for procedures of technical diagnostics. It also creates direct relations between the law of the state parameter changes and reliability of the considered power plant components.

Productivity growth and biased technological change in hydroelectric dams  

Science Journals Connector (OSTI)

This paper analyses productivity growth and the nature of technical change in a sample of Portuguese hydroelectric generating plants over the period 2001 to 2008. In a first step, we employ the Luenberger productivity indicator to estimate and decompose productivity change. A Malmquist productivity index is also used for a comparative purpose. The results paint a picture of mixed productivity performance in the Portuguese energy sector. The first decomposition underlines that, in average, the productivity variation is explained by the technological change. Then, in a second step, we analyse the nature of this technical change by using the recent concept of parallel neutrality (Briec et al., 2006). We observe a global shift in the best practice frontier as well as in the evidence of input bias in technical change.

Environmental mitigation at hydroelectric projects. Volume 2, Benefits and costs of fish passage and protection  

SciTech Connect (OSTI)

This study examines envirorunental mitigation practices that provide upstream and downstream fish passage and protection at hydroelectric projects. The study includes a survey of fish passage and protection mitigation practices at 1,825 hydroelectric plants regulated by the Federal Energy Regulatory Commission (FERC) to determine frequencies of occurrence, temporal trends, and regional practices based on FERC regions. The study also describes, in general terms, the fish passage/protection mitigation costs at 50 non-Federal hydroelectric projects. Sixteen case studies are used to examine in detail the benefits and costs of fish passage and protection. The 16 case studies include 15 FERC licensed or exempted hydroelectric projects and one Federally-owned and-operated hydroelectric project. The 16 hydroelectric projects are located in 12 states and range in capacity from 400 kilowatts to 840 megawatts. The fish passage and protection mitigation methods at the case studies include fish ladders and lifts, an Eicher screen, spill flows, airburst-cleaned inclined and cylindrical wedgewire screens, vertical barrier screens, and submerged traveling screens. The costs, benefits, monitoring methods, and operating characteristics of these and other mitigation methods used at the 16 case studies are examined.

Strategic analysis of the Great Canadian Hydroelectric Power Conflict  

Science Journals Connector (OSTI)

Abstract The contract negotiation that led to the 1969 agreement between Newfoundland and Labrador,and Quebec, is systemically analyzed within the framework of Graph Model for Conflict Resolution. The Great Canadian Hydroelectric Power Conflict has been ongoing since 1963 and shows no signs of ending. In this dispute, the Province of Quebec has the right to buy almost all of the power generated from the Upper Churchill Falls, which is located in the Labrador territory in Newfoundland and Labrador, at a very low price. Originally, the contract was signed by Churchill Falls Labrador Corporation to secure finances for the Upper Churchill Falls development. The unpopularity of the contract led to several unsuccessful attempts by the Newfoundland and Labrador Government to escape its provisions. Newfoundland and Labrador is currently negotiating to develop the Lower Churchill Project and seeking to avoid the mistakes of the first contract. Furthermore, the automatic renewal clause of the original contract is expected to cause another round of conflict in 2016. The analysis shows that, given the circumstances in which the agreement was signed, the outcome was almost inevitable. Athird party intervener rule could have remediated the damage caused by the conflict.

Final Technical Report - Modernization of the Boulder Canyon Hydroelectric Project  

SciTech Connect (OSTI)

The Boulder Canyon Hydroelectric Project (BCH) was purchased by the City of Boulder, CO (the city) in 2001. Project facilities were originally constructed in 1910 and upgraded in the 1930s and 1940s. By 2009, the two 10 MW turbine/generators had reached or were nearing the end of their useful lives. One generator had grounded out and was beyond repair, reducing plant capacity to 10 MW. The remaining 10 MW unit was expected to fail at any time. When the BCH power plant was originally constructed, a sizeable water supply was available for the sole purpose of hydroelectric power generation. Between 1950 and 2001, that water supply had gradually been converted to municipal water supply by the city. By 2001, the water available for hydroelectric power generation at BCH could not support even one 10 MW unit. Boulder lacked the financial resources to modernize the facilities, and Boulder anticipated that when the single, operational historical unit failed, the project would cease operation. In 2009, the City of Boulder applied for and received a U.S. Department of Energy (DOE) grant for $1.18 million toward a total estimated project cost of $5.155 million to modernize BCH. The federal funding allowed Boulder to move forward with plant modifications that would ensure BCH would continue operation. Federal funding was made available through the American Recovery and Reinvestment Act (ARRA) of 2009. Boulder determined that a single 5 MW turbine/generator would be the most appropriate capacity, given the reduced water supply to the plant. Average annual BCH generation with the old 10 MW unit had been about 8,500 MW-hr, whereas annual generation with a new, efficient turbine could average 11,000 to 12,000 MW-hr. The incremental change in annual generation represents a 30% increase in generation over pre-project conditions. The old turbine/generator was a single nozzle Pelton turbine with a 5-to-1 flow turndown and a maximum turbine/generator efficiency of 82%. The new unit is a double nozzle Pelton turbine with a 10-to-1 flow turndown and a maximum turbine/generator efficiency of 88%. This alone represents a 6% increase in overall efficiency. The old turbine operated at low efficiencies due to age and non-optimal sizing of the turbine for the water flow available to the unit. It was shut down whenever water flow dropped to less than 4-5 cfs, and at that flow, efficiency was 55 to 60%. The new turbine will operate in the range of 70 to 88% efficiency through a large portion of the existing flow range and would only have to be shut down at flow rates less than 3.7 cfs. Efficiency is expected to increase by 15-30%, depending on flow. In addition to the installation of new equipment, other goals for the project included: ?¢???¢ Increasing safety at Boulder Canyon Hydro ?¢???¢ Increasing protection of the Boulder Creek environment ?¢???¢ Modernizing and integrating control equipment into Boulder?¢????s municipal water supply system, and ?¢???¢ Preserving significant historical engineering information prior to power plant modernization. From January 1, 2010 through December 31, 2012, combined consultant and contractor personnel hours paid for by both the city and the federal government have totaled approximately 40,000. This equates roughly to seven people working full time on the project from January 2010 through December 2012. This project also involved considerable material expense (steel pipe, a variety of valves, electrical equipment, and the various components of the turbine and generator), which were not accounted for in terms of hours spent on the project. However, the material expense related to this project did help to create or preserve manufacturing/industrial jobs throughout the United States. As required by ARRA, the various components of the hydroelectric project were manufactured or substantially transformed in the U.S. BCH is eligible for nomination to

Optimization of solar assisted ground source heat pump system for space heating application by Taguchi method and utility concept  

Science Journals Connector (OSTI)

Abstract In the present research, a methodology is proposed to optimize the solar collector area and ground heat exchanger length for achieving higher COP of Solar Assisted Ground Source Heat Pump (SAGSHP) system using Taguchi method and utility concept. Four operating parameters for solar collector and four parameters for ground heat exchanger have been selected with mixed level variation using an L18 (21, 37) orthogonal array. The key parameters such as solar collector area, ground heat exchanger length and COP of the SAGSHP system are optimized to predict the best levels of operating parameters for maximum COP of SAGSHP system. Lower the better concept has been used for the solar collector area and ground heat exchanger length whereas higher the better concept has been employed for the COP of SAGSHP system and the results have been analyzed for the optimum conditions using signal-to-noise (SN) ratio and ANOVA method. Computations were carried out for 18 experimental trial runs by considering 2ton heating load in winter season. The optimum COP for SAGSHP was estimated to be 4.23 from the utility concept, which is 8.74% higher than the optimum COP predicted by Taguchi optimization. Optimization of solar collector area and ground heat exchanger length by the utility concept has shown only about 2.3% reduction in area and 1.6% reduction in length respectively compared to those values optimized by the Taguchi method.

The Leo Archipelago: A System of Earth-Rings for Communications, Mass-Transport to Space, Solar Power, and Control of Global Warming  

E-Print Network [OSTI]

A multi-purpose low-earth-orbit system of rings circling the earth - the "LEO ARCHIPELAGO" - is proposed as a means of solving or bypassing many major problems hindering man's quest to get into space. A fiber-optic ring about the earth would be an initial testing and developmental stage for the ring systems, while providing cash-flow through a LEO-based, high-band-width, world-wide communication system. A Low-Earth-Orbit-based space-elevator system, "Sling-on-a-Ring," is proposed as the crucial developmental stage of the LEO Archipelago. Being a LEO-based heavy-mass lifter, rather than earth- or GEO-based, it is much less massive and therefore less costly than other proposed space-elevators. With the advent of lower-cost, higher-mass transport to orbit, the options for further space development (e.g., communications, space solar power, radiation dampers, sun shades, and permanent LEO habitation) are greatly expanded. This paper provides an update of the Sling-on-a-Ring concept in terms of new materials, poten...

Underwater noise generated by Columbia River hydroelectric dams  

Science Journals Connector (OSTI)

Low?frequency (101000 Hz) underwater noise measurements have been made in water within and upstream from four Columbia River hydroelectric dams. The motivation for these measurements was to map out the sound field within and upstream from the power dams as a first step in understanding the effect of this field on the behavior of migrating salmonids that must choose between the bypass system or intakes to the turbines. Eventually sound may be used to guide the juvenile fish safely past the turbine intakes and into the bypass system. Thus far single hydrophonemeasurements have been made in the bypass slots within the dam and at a number of locations upstream from the dam. The noise level varies with location decreasing as the hydrophone is moved upsteam from the dam and as the hydrophone is moved closer to the water surface immediately upstream of the dam as well as in the bypass slot. The noise spectra below 200 Hz are highly modulated displaying one or more sharp peaks which indicates resonances in the structural generating mechanism or propagation path. The spectrum level and modulation vary significantly from one dam to another and sometimes from one configuration to another (e.g. when one of the turbines is on or off). A final set of measurements will be made at the Bonneville Dam using several hydrophones placed at a number of locations in the vicinity of the intake channel and these may help identify sources and propagation paths to the hydrophone.

New vision solar system exploration missions study: Analysis of the use of biomodal space nuclear power systems to support outer solar system exploration missions. Final report  

SciTech Connect (OSTI)

This report presents the results of an analysis of the capability of nuclear bimodal systems to perform outer solar system exploration missions. Missions of interest include orbiter mission s to Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. An initial technology baseline consisting of a NEBA 10 kWe, 1000 N thrust, 850 s, 1500 kg bimodal system was selected, and its performance examined against a data base for trajectories to outer solar system planetary destinations to select optimal direct and gravity assisted trajectories for study. A conceptual design for a common bimodal spacecraft capable of performing missions to all the planetary destinations was developed and made the basis of end to end mission designs for orbiter missions to Jupiter, Saturn, and Neptune. Concepts for microspacecraft capable of probing Jupiter`s atmosphere and exploring Titan were also developed. All mission designs considered use the Atlas 2AS for launch. It is shown that the bimodal nuclear power and propulsion system offers many attractive option for planetary missions, including both conventional planetary missions in which all instruments are carried by a single primary orbiting spacecraft, and unconventional missions in which the primary spacecraft acts as a carrier, relay, and mother ship for a fleet of micro spacecraft deployed at the planetary destination.

Solar collector  

SciTech Connect (OSTI)

A solar collector is disclosed which is tiltable about a horizontal axis so as to vary the angle at which solar radiation is received by the collector. The solar collector, which uses air as the heat transfer medium, has connected to it a pair of fixed, well-insulated air transfer passages which penetrate through into the interior of the collector at the lateral sides thereof aligned with the horizontal axis about which the collector is pivoted. The air transfer passages are insulated and are gasketed to the sides of the collector so as to improve the efficiency of the solar energy system by avoiding losses of heat from the heat transfer fluid during transfer of the fluid from the collector to the space being heated.

OBSERVATIONS OF THE 2006 DECEMBER 13 AND 14 SOLAR PARTICLE EVENTS IN THE 80 MeV n{sup -1}-3 GeV n{sup -1} RANGE FROM SPACE WITH THE PAMELA DETECTOR  

SciTech Connect (OSTI)

We present the space spectrometer PAMELA observations of proton and helium fluxes during the 2006 December 13 and 14 solar particle events. This is the first direct measurement of the solar energetic particles in space with a single instrument in the energy range from {approx}80 MeV n{sup -1} up to {approx}3 GeV n{sup -1}. For the December 13 event, measured energy spectra of solar protons and helium are compared with results obtained by neutron monitors and other detectors. Our measurements show a spectral behavior different from those derived from the neutron monitor network. No satisfactory analytical fitting was found for the energy spectra. During the first hours of the December 13 event, solar energetic particles spectra were close to the exponential form, demonstrating rather significant temporal evolution. Solar He with energy up to 1 GeV n{sup -1} was recorded on December 13. For the December 14 event, energy of solar protons reached 600 MeV, whereas the maximum energy of He was below 100 MeV n{sup -1}. The spectra were slightly bent in the lower energy range and preserved their form during the second event. Differences in the particle flux appearance and temporal evolution of these two events may argue for special conditions leading to the acceleration of solar particles up to relativistic energies.

Water development for hydroelectric in southeastern Anatolia project (GAP) in Turkey  

Science Journals Connector (OSTI)

Southeastern Anatolia Project (GAP) region in Turkey is rich in water for irrigation and hydroelectric power. The Euphrates and Tigris rivers represent over 28% of the nations water supply by rivers, and the economically irrigable areas in the region make up 20% of those for the entry country. On the other hand, 85% of the total hydro capacity in operation has been developed by DSI, corresponding to 9931MW (49 hydro plants) and 35,795GWh/year respectively. The largest and most comprehensive regional development project ever implemented by DSI in Turkey is The Southeast Anatolian (GAP) Project, which is located in the region of Southeast Anatolia on the Euprates and Tigris rivers and their tributaries, which originate in Turkey. The energy potential of the Tigris and Euphrates is estimated as 12,000GWh and 35,000GWh, respectively. These two rivers constitute 10% and 30% of the total hydroelectric energy potential. The GAP region will be an important electric power producer with 1000MW installed capacity from the Karakaya dam, 2400MW installed capacity from the Atatrk dam and 1360MW installed capacity from the Keban dam. The GAP region has a 22% share of the countrys total hydroelectric potential, with plans for 22 dams and 19 hydroelectric power plants. Once completed, 27 billionkWh of electricity will be generated annually.

What is the role of hydroelectric power in the United States?  

Reports and Publications (EIA)

The importance of hydropower as a source of electricity generation varies by geographic region. While hydropower accounted for 6% of total U.S. electricity generation in 2010, it provided over half of the electricity in the Pacific Northwest. Because hydroelectric generation relies on precipitation, it varies widely from month to month and year to year.

Report on technical feasibility of underground pumped hydroelectric storage in a marble quarry site in the Northeast United States  

SciTech Connect (OSTI)

The technical and economic aspects of constructing a very high head underground hydroelectric pumped storage were examined at a prefeasibility level. Excavation of existing caverns in the West Rutland Vermont marble quarry would be used to construct the underground space. A plant capacity of 1200 MW and 12 h of continuous capacity were chosen as plant operating conditions. The site geology, plant design, and electrical and mechanical equipment required were considered. The study concluded that the cost of the 1200 MW underground pumped storage hydro electric project at this site even with the proposed savings from marketable material amounts to between $581 and $595 per kilowatt of installed capacity on a January 1982 pricing level. System studies performed by the planning group of the New England Power System indicate that the system could economically justify up to about $442 per kilowatt on an energy basis with no credit for capacity. To accommodate the plant with the least expensive pumping energy, a coal and nuclear generation mix of approximately 65% would have to be available before the project becomes feasible. It is not expected that this condition can be met before the year 2000 or beyond. It is therefore concluded that the West Rutland underground pumped storage facility is uneconomic at this time. Several variables however could have marked influence on future planning and should be examined on periodic basis.

Efficiency analysis of hydroelectric generating plants: A case study for Portugal  

Science Journals Connector (OSTI)

This paper estimates changes in total productivity, breaking this down into technically efficient change and technological change, by means of data envelopment analysis (DEA) applied to the hydroelectric energy generating plants of EDP the Portugal Electricity Company. The aim of this procedure is to seek out those best practices that will lead to improved performance in the energy market. We rank the plants according to their change in total productivity for the period 20012004, concluding that some plants experienced productivity growth while others experienced a decrease in productivity. The implications arising from the study are that EDP should adopt an internal benchmark management procedure in order to evaluate the relative position of each hydroelectric generating plant and to adopt managerial strategies designed to catch up with the frontier of best practices. As the frontier is shifting along the time, constant efforts are needed in this respect along the time.

Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility  

SciTech Connect (OSTI)

Final Technical Report for the Recovery Act Project for the Installation of a Low Flow Unit at the Abiquiu Hydroelectric Facility. The Abiquiu hydroelectric facility existed with two each 6.9 MW vertical flow Francis turbine-generators. This project installed a new 3.1 MW horizontal flow low flow turbine-generator. The total plant flow range to capture energy and generate power increased from between 250 and 1,300 cfs to between 75 and 1,550 cfs. Fifty full time equivalent (FTE) construction jobs were created for this project - 50% (or 25 FTE) were credited to ARRA funding due to the ARRA 50% project cost match. The Abiquiu facility has increased capacity, increased efficiency and provides for an improved aquatic environment owing to installed dissolved oxygen capabilities during traditional low flow periods in the Rio Chama. A new powerhouse addition was constructed to house the new turbine-generator equipment.

Induced hydroelectric energy generated by compressing a single-walled carbon nanotube hydrogel  

Science Journals Connector (OSTI)

Using single-walled carbon nanotubes (SWCNTs) for energy harvesting and storage have attracted much attention recently because SWCNTs have supercapacity performance. In this paper we report a simple electromechanical approach for the generation of induced electrical potential by the compression of a SWCNT-triggered sodium deoxycholate hydrogel. This hydrogel enhances the electrical potential generated under compression and this is mainly because of the generation of hydroelectric power by the flow of water over the SWCNTs. The induced voltage was 63.1?mV upon the compression of a 4% SWCNT hydrogel to a compression ratio of 50% which is superior to values reported previously. The enhancement in hydroelectric potential increased with SWCNT loading in the hydrogel and with the compression ratio because of an enhancement of the impact frequency between water molecules and the SWCNTs.

Giant otter population responses to habitat expansion and degradation induced by a mega hydroelectric dam  

Science Journals Connector (OSTI)

Abstract Large hydroelectric dams are major drivers of habitat loss and degradation in lowland Amazonia. Hydroelectric reservoirs reduce the habitat available for terrestrial species, but create new open-water and shoreline lake habitat that can potentially boost populations of aquatic and semi-aquatic species, such as the threatened giant otter (Pteronura brasiliensis). To assess the impacts of mega-dams on this apex-predator, we surveyed the giant otter population across the 443,772-hectare Balbina Hydroelectric Reservoir of central Brazilian Amazonia between 14 and 25years after this reservoir creation. We compared changes in habitat area and estimated giant otter population size between the reservoir pre- and post-filling stages. The Balbina dam created ?3525 islands and increased the open-water surface and total reservoir perimeter available to otters by a factor of 62.7 and 8.9, respectively. Some 25years after damming, however, the estimated post-filling giant otter population size was only twice greater than that estimated before filling and 4.5 times smaller than would be predicted given the total available habitat area and density of dens quantified at a neighbouring undisturbed area used as a surrogate of the pre-filling phase. The observed mismatch between the proportional increase in otter population size and the much greater newly available reservoir habitat area is likely due to low habitat quality in terms of low fish prey productivity and scarcity of suitable sites for denning and territory demarcation. This should be considered in strategic environmental impact assessments of planned hydroelectric dams and in managing existing and future hydropower development in lowland tropical forests.

The real estate parcel must include the requisite interest in the land adjacent to the watercourse, access to the underlying streambed and where needed, the land necessary for an upstream impoundment area. Land acquisition may be effectuated by purchase, lease, or grant by the state. In addition to these methods, New York permits the use of the eminent domain power of the state for public utilities under certain circumstances.

Innovative reservoir sediments reuse and design for sustainability of the hydroelectric power plants  

Science Journals Connector (OSTI)

Abstract In the process of producing hydroelectricity, plants all over the world are faced with the problem of reservoir sediment. If this sediment is removed but not properly disposed of, it can become a secondary pollutant. This study proposes a way to resolve this problem through reuse and recycling. In this study, the process is based on Design for Six Sigma (DFSS) where reservoir sediment and the masonry waste from the construction industry are combined with cement and a curing agent. The resulting mixture transforms into a high strength, non-sintered cured brick after 28 days of natural curing. This product is a new walling material that is friendly to environment, fulfill the goal of energy conservation, waste recycle, protect ecosystems, and promote sustainable development. Large scale recycling of reservoir sediment solves the problems that reservoir sediment poses, as well as increasing the capacity of reservoirs and the effectiveness of hydroelectric power plants. The green milestone reached by the technology is of great industrial, economic and social significance.

Can Fish Morphological Characteristics be Used to Re-design Hydroelectric Turbines?  

SciTech Connect (OSTI)

Safe fish passage affects not only migratory species, but also populations of resident fish by altering biomass, biodiversity, and gene flow. Consequently, it is important to estimate turbine passage survival of a wide range of susceptible fish. Although fish-friendly turbines show promise for reducing turbine passage mortality, experimental data on their beneficial effects are limited to only a few species, mainly salmon and trout. For thousands of untested species and sizes of fish, the particular causes of turbine passage mortality and the benefits of fish-friendly turbine designs remain unknown. It is not feasible to measure the turbine-passage survival of every species of fish in every hydroelectric turbine design. We are attempting to predict fish mortality based on an improved understanding of turbine-passage stresses (pressure, shear stress, turbulence, strike) and information about the morphological, behavioral, and physiological characteristics of different fish taxa that make them susceptible to the stresses. Computational fluid dynamics and blade strike models of the turbine environment are re-examined in light of laboratory and field studies of fish passage effects. Comparisons of model-predicted stresses to measured injuries and mortalities will help identify fish survival thresholds and the aspects of turbines that are most in need of re-design. The coupled model and fish morphology evaluations will enable us to make predictions of turbine-passage survival among untested fish species, for both conventional and advanced turbines, and to guide the design of hydroelectric turbines to improve fish passage survival.

Drivers of phytoplankton, bacterioplankton, and zooplankton carbon biomass in tropical hydroelectric reservoirs  

Science Journals Connector (OSTI)

Abstract Studies of carbon sources in plankton communities are important because carbon content has become the main currency used in functional studies of aquatic ecosystems. We evaluated the contribution to the total organic carbon pool from different plankton communities (phytoplankton, bacterioplankton, and zooplankton C-biota) and its drivers in eight tropical hydroelectric reservoirs with different trophic and hydrological status and different physical features. Our systems were separated into three groups based on trophic status and water residence time: (i) mesotrophic with low residence time (ML); (ii) mesotrophic with high residence time (MH); and (iii) eutrophic with low residence time (EL). Our hypothesis that reservoirs with low water residence times and low nutrient concentrations would show the lowest C-biota was supported. Phytoplankton carbon (C-phy) showed the highest concentrations in the EL, followed by MH and ML systems. The EL group also showed significantly higher zooplankton carbon (C-zoo). No significant difference was observed for bacteria carbon (C-bac) among the three system groups. In addition to trophic status and water residence time, regression analyses revealed that water temperature, light, pH, and dissolved organic carbon concentrations were the main drivers of plankton communities in these large tropical hydroelectric reservoirs.

energy energy Radiant energy emitted by the sun[1] View on Wikipedia Wikipedia Definition Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Incorporating daily flood control objectives into a monthly stochastic dynamic programming model for a hydroelectric complex  

SciTech Connect (OSTI)

A monthly stochastic dynamic programing model was recently developed and implemented at British Columbia (B.C.) Hydro to provide decision support for short-term energy exports and, if necessary, for flood control on the Peace River in northern British Columbia. The model established the marginal cost of supplying energy from the B.C. Hydro system, as well as a monthly operating policy for the G.M. Shrum and Peace Canyon hydroelectric plants and the Williston Lake storage reservoir. A simulation model capable of following the operating policy then determines the probability of refilling Williston Lake and possible spill rates and volumes. Reservoir inflows are input to both models in daily and monthly formats. The results indicate that flood control can be accommodated without sacrificing significant export revenue.

Simulation of quantum dots size and spacing effect for intermediate band solar cell application based on InAs quantum dots arrangement in GaAs  

SciTech Connect (OSTI)

Intermediate band solar cell (IBSC) has become a promising technology in increasing solar cell efficiency. In this work we compare absorption coefficient profile between InAs quantum dots with GaAs bulk. We calculate the efficiency of GaAs bulk and GaAs doped with 2, 5, and 10 nm InAs quantum dot. Effective distances in quantum dot arrangement based on electron tunneling consideration were also calculated. We presented a simple calculation method with low computing power demand. Results showed that arrangement of quantum dot InAs in GaAs can increase solar cell efficiency from 23.9 % initially up to 60.4%. The effective distance between two quantum dots was found 2 nm in order to give adequate distance to prevent electron tunneling and wave functions overlap.

A HIRARC model for safety and risk evaluation at a hydroelectric power generation plant  

Science Journals Connector (OSTI)

Abstract There are many formal techniques for the systematic analysis of occupational safety and health in general, and risk analysis in particular, for power generation plants at hydroelectric power stations. This study was initiated in order to create a HIRARC model for the evaluation of environmental safety and health at a hydroelectric power generation plant at Cameron Highlands in Pahang, Malaysia. The HIRARC model was used to identify the primary and secondary hazards which may be inherent in the system which were determined as a serious threat for plant operation and maintenance. The primary tools of the model consisted of, generic check-lists, work place inspection schemes which included task observation and interview, safety analysis as well as accident and incident investigation. For risk assessment, the Likert scale was complemented by the severity matrix analysis in order to determine the probability and extent of safety and health at the study power generation plant. These were used to identify and recommend control measures which included engineering and administrative aspects as well as the use of personal protective equipment (PPE). A total of forty-one important hazard items were identified in the system at target power generation plant. These hazards were mainly identified by means of checklists which were sourced from literature and subsequently customized for the current purpose. Risk assessment was conducted by initially classifying the hazards into three levels such as Low, Medium and High. Generally 66% of the hazards identified were at low risk, 32% at medium and 2% at high risk. This indicated that there was sufficient awareness and commitment to safety and health at the study power station. Meanwhile the Power Station was also certified by MS 1722:2005, OHSAS 18001, MS ISO 14001:2004, MS ISO 9001:2000 and scheduled waste regulation 2005 which give credibility to the current study in creating a working model which may find widespread application in the future.

Short-term cascaded hydroelectric system scheduling based on chaotic particle swarm optimization using improved logistic map  

Science Journals Connector (OSTI)

In order to solve the model of short-term cascaded hydroelectric system scheduling, a novel chaotic particle swarm optimization (CPSO) algorithm using improved logistic map is introduced, which uses the water discharge as the decision variables combined with the death penalty function. According to the principle of maximum power generation, the proposed approach makes use of the ergodicity, symmetry and stochastic property of improved logistic chaotic map for enhancing the performance of particle swarm optimization (PSO) algorithm. The new hybrid method has been examined and tested on two test functions and a practical cascaded hydroelectric system. The experimental results show that the effectiveness and robustness of the proposed CPSO algorithm in comparison with other traditional algorithms.

A novel KICAPCA fault detection model for condition process of hydroelectric generating unit  

Science Journals Connector (OSTI)

Abstract Fault detection and diagnosis of hydroelectric generating unit (HGU) have significant importance to the security of hydropower plant and the power system. In recent years, many fault detection methods based on spectral characteristic of vibration signals have been published. However, some faults cannot be effectively recognized just with spectral features for condition process monitoring of HGU. Thus, this study presents a novel fault detection model based on kernel independent component analysis and principal component analysis (KICAPCA) monitoring model for condition process of HGU. Each of the condition processes is equivalent to a multivariate statistical process monitoring (MSPM). KICAPCA model of the specific MSPM is trained by normal condition process data at first. Then, confidence limits of two monitoring indices (Hotellings T2 statistic and SPE statistic) of the trained KICAPCA model are used to monitor the same condition process and detect fault online. Moreover, the proposed monitoring model is applied to a real condition process of HGU. Compared to ICAPCA and PCA monitoring model, the proposed model has superior performance in fault detection.

Hydroelectric power plant management relying on neural networks and expert system integration  

Science Journals Connector (OSTI)

The use of Neural Networks (NN) is a novel approach that can help in taking decisions when integrated in a more general system, in particular with expert systems. In this paper, an architecture for the management of hydroelectric power plants is introduced. This relies on monitoring a large number of signals, representing the technical parameters of the real plant. The general architecture is composed of an Expert System and two NN modules: Acoustic Prediction (NNAP) and Predictive Maintenance (NNPM). The NNAP is based on Kohonen Learning Vector Quantization (LVQ) Networks in order to distinguish the sounds emitted by electricity-generating machine groups. The NNPM uses an ART-MAP to identify different situations from the plant state variables, in order to prevent future malfunctions. In addition, a special process to generate a complete training set has been designed for the ART-MAP module. This process has been developed to deal with the absence of data about abnormal plant situations, and is based on neural nets trained with the backpropagation algorithm.

Spring-Supported thrust bearings for hydroelectric generators: Influence of oil viscosity on power loss  

Science Journals Connector (OSTI)

Energy losses in the spring-supported thrust bearings used in many large hydroelectric generator units were estimated to be small compared to the rate of energy (power) generation but, nevertheless, commercially significant. The purpose of the present study was examine the influence of oil viscosity on power loss. Experiments were performed using a test facility containing a thrust bearing of 1.2 m outer diameter and both power loss and temperature rise were measured for oils of ISO grade 32, 46 and 68, all at various oil pot temperatures. Power loss and temperature rise decreased as the viscosity of the oil in the oil pot decreased. Minimum oil film thicknesses were predicted with numerical analysis using a specialized software package (GENMAT). The accuracy of this calculation was supported by the good agreement between the temperature rise predicted by numerical analysis and the experimentally determined values. Provided film thickness were adequate to avoid any danger of wiping (10 15 ?m), the present study showed clearly that significant energy savings could be realized in the large spring-supported thrust bearings and associated guide bearings by lowering oil viscosities.

Life cycle assessment of a community hydroelectric power system in rural Thailand  

Science Journals Connector (OSTI)

Rural electrification and the provision of low cost, low emission technology in developing countries require decision makers to be well informed on the costs, appropriateness and environmental credentials of all available options. While cost and appropriateness are often shaped by observable local considerations, environmental considerations are increasingly influenced by global concerns which are more difficult to identify and convey to all stakeholders. Life cycle assessment is an iterative process used to analyse a product or system. This study iteratively applies life cycle assessment (LCA) to a 3kW community hydroelectric system located in Huai Kra Thing (HKT) village in rural Thailand. The cradle to grave analysis models the hydropower schemes construction, operation and end of life phases over a period of twenty years and includes all relevant equipment, materials and transportation. The study results in the enumeration of the environmental credentials of the HKT hydropower system and highlights the need to place environmental performance, and LCA itself, in a proper context. In the broadest sense, LCA results for the HKT hydropower system are found to reflect a common trend reported in hydropower LCA literature, namely that smaller hydropower systems have a greater environmentally impact per kWh perform less well environmentally - than larger systems. Placed within a rural electrification context, however, the HKT hydropower system yields better environmental and financial outcomes than diesel generator and grid connection alternatives.

A case study on thrust bearing failures at the SO SIMO hydroelectric power plant  

Science Journals Connector (OSTI)

Abstract After twenty years without any apparent problems on their combined guide and thrust bearings, the six 280MW hydrogenerators of the So Simo Hydroelectric Power Plant were failing. The source of the failure was the melting of the thrust pad babbitt lining. The machines began showing performance failures, leading to a sudden interruption in their operation. This caused considerable losses with high direct and indirect costs. The solution proposed by the bearing manufacturer was an improvement in the bearing design and the installation of new wateroil heat exchangers. The direct cost of their solution was estimated to be US $2,400,000.00. In a search for a less expensive alternative, CEMIG started a parallel study focused on the heat exchangers. A methodology based on heat transfer was applied, indicating that an increase in the heat exchange surface area could solve the problem. A third heat exchanger was added in one machine that already possessed two. The results fulfilled the preliminary predictions, eliminating the risk of additional babbitt lining failures. As a consequence of this success modeling, heat exchangers were replaced by stainless steel plate ones in all machines. This alternative solution had a total direct cost of US $600,000.00.

Observations of Velocity Conditions near a Hydroelectric Turbine Draft Tube Exit using ADCP Measurements  

SciTech Connect (OSTI)

Measurement of flow characteristics near hydraulic structures is an ongoing challenge because of the need to obtain rapid measurements of time-varying velocity over a relatively large spatial domain. This paper discusses use of an acoustic Doppler current profiler (ADCP) to measure the rapidly diverging flow exiting from an operating hydroelectric turbine draft tube exit. The resolved three-dimensional velocity vectors show a highly complex and helical flow pattern developed near to and downstream of the exit. Velocity vectors were integrated across the exit and we computed an uneven percentage of flow (67%/33%) passing through the two draft tube barrels at a mid-range turbine discharge, consistent with physical model results. In addition to the three-dimensional velocity vectors, the individual one-dimensional velocities measured by each of the four ADCP beams can be separately used as calibration and validation datasets for numerical and physical models. This technique is demonstrated by comparing along-beam ADCP velocity measurements to data collected in a scaled physical model.

Development of an HTS hydroelectric power generator for the hirschaid power station  

Science Journals Connector (OSTI)

This paper describes the development and manufacture of a 1.7MW, 5.25kV, 28pole, 214rpm hydroelectric power generator consisting of superconducting HTS field coils and a conventional stator. The generator is to be installed at a hydro power station in Hirschaid, Germany and is intended to be a technology demonstrator for the practical application of superconducting technology for sustainable and renewable power generation. The generator is intended to replace and uprate an existing conventional generator and will be connected directly to the German grid. The HTS field winding uses Bi-2223 tape conductor cooled to about 30K using high pressure helium gas which is transferred from static cryocoolers to the rotor via a bespoke rotating coupling. The coils are insulated with multi-layer insulation and positioned over laminated iron rotor poles which are at room temperature. The rotor is enclosed within a vacuum chamber and the complete assembly rotates at 214rpm. The challenges have been significant but have allowed Converteam to develop key technology building blocks which can be applied to future HTS related projects. The design challenges, electromagnetic, mechanical and thermal tests and results are presented and discussed together with applied solutions.

In Outer Space without a Space Suit?  

E-Print Network [OSTI]

The author proposes and investigates his old idea - a living human in space without the encumbrance of a complex space suit. Only in this condition can biological humanity seriously attempt to colonize space because all planets of Solar system (except the Earth) do not have suitable atmospheres. Aside from the issue of temperature, a suitable partial pressure of oxygen is lacking. In this case the main problem is how to satiate human blood with oxygen and delete carbonic acid gas (carbon dioxide). The proposed system would enable a person to function in outer space without a space suit and, for a long time, without food. That is useful also in the Earth for sustaining working men in an otherwise deadly atmosphere laden with lethal particulates (in case of nuclear, chemical or biological war), in underground confined spaces without fresh air, under water or a top high mountains above a height that can sustain respiration.

In Outer Space without a Space Suit?  

E-Print Network [OSTI]

The author proposes and investigates his old idea - a living human in space without the encumbrance of a complex space suit. Only in this condition can biological humanity seriously attempt to colonize space because all planets of Solar system (except the Earth) do not have suitable atmospheres. Aside from the issue of temperature, a suitable partial pressure of oxygen is lacking. In this case the main problem is how to satiate human blood with oxygen and delete carbonic acid gas (carbon dioxide). The proposed system would enable a person to function in outer space without a space suit and, for a long time, without food. That is useful also in the Earth for sustaining working men in an otherwise deadly atmosphere laden with lethal particulates (in case of nuclear, chemical or biological war), in underground confined spaces without fresh air, under water or a top high mountains above a height that can sustain respiration.

Images of energy: Policy perspectives on the introduction of hydroelectricity in Italy, 1882-1914  

SciTech Connect (OSTI)

This study considers the link between energy technologies and cultural attitudes. Contemporary energy policy makers lack the conceptual tools with which to evaluate culturally appropriate energy choices. A way to regain a contextual capability is needed; that is, the capacity to recognize and avert situations where technological advance is insufficiently harmonized with its embedding environment. This study explores how both policy makers and the general public form their [open quotes]images of energy.[close quotes] It does so in three parts, beginning with an examination of the concepts of [open quotes]technology,[close quotes] [open quotes]culture[close quotes] and [open quotes]cognitive map,[close quotes] and an explanation of their interrelationship. The second part presents two historical case-studies of the introduction of hydroelectricity in Italy from 1882-1914. It considers how a relatively unknown technology made its way into urban and rural life, who its primary surveyors were, and how it shaped and was shaped by the cognitive maps of those into whose lives it marched. The final part extends the investigation to contemporary socio-cultural dynamics. Through concepts derived from General System Theory, the process of technological integration is interpreted in light of events that shape the world today. The design of a model to be used by energy makers and educators alike in conceiving culturally attuned energy alternatives is proposed. Such a model would describe energy-related cognitive maps and could serve as the basis for informed decision-making on energy choice at all levels of society. The study concludes with suggestions for a research agenda to further explore individual and collective energy-related cognitive maps.

Active Solar Heating Basics | Department of Energy  

Broader source: Energy.gov (indexed) [DOE]

Active Solar Heating Basics Active Solar Heating Basics Active Solar Heating Basics August 16, 2013 - 3:23pm Addthis There are two basic types of active solar heating systems based on the type of fluid-either liquid or air-that is heated in the solar energy collectors. The collector is the device in which a fluid is heated by the sun. Liquid-based systems heat water or an antifreeze solution in a "hydronic" collector, whereas air-based systems heat air in an "air collector." Both of these systems collect and absorb solar radiation, then transfer the solar heat directly to the interior space or to a storage system, from which the heat is distributed. If the system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat. Liquid systems are more often used when storage is included, and are well

The solar siblings in the Gaia era  

E-Print Network [OSTI]

We perform realistic simulations of the Sun's birth cluster in order to predict the current distribution of solar siblings in the Galaxy. We study the possibility of finding the solar siblings in the Gaia catalogue by using only positional and kinematic information. We find that the number of solar siblings predicted to be observed by Gaia will be around 100 in the most optimistic case, and that a phase space only search in the Gaia catalogue will be extremely difficult. It is therefore mandatory to combine the chemical tagging technique with phase space selection criteria in order to have any hope of finding the solar siblings.

Experience in operating and reconstructing the turbine bearings of units of the Sayano-Shushenskoe hydroelectric station  

SciTech Connect (OSTI)

This article reviews some of the operations and maintenance experiences at the Sayano-Shushenskoe hydroelectric sstation in Russia. In particular, the experiences gained in the operation of the turbines and the reconstruction of the turbine bearings are noted. The compact layout of this facility did not permit the traditional babbitt bearing or rubber ring bearing with water lubrication. Instead, a rubber sugmented bearing with water lubrication was used. The design and construction of this bearing, as well as the operation and maintenance of this bearing, is discussed in this article. The operating experiences have shown that the component is highly reliable.

Integrated solar collector  

DOE Patents [OSTI]

A solar collector having a copper panel in a contiguous space relationship with a condenser-evaporator heat exchanger located under the panel, the panel having a honeycomb-like structure on its interior defining individual cells which are filled with zeolite loaded, in its adsorbed condition, with 18 to 20% by weight of water. The interior of the panel and heat exchanger are maintained at subatmospheric pressure of about 0.1 to 1 psia. The panel and heat exchanger are insulated on their lateral sides and bottoms and on the top of the heat exchange. The panel has a black coating on its top which is exposed to and absorbs solar energy. Surrounding the insulation (which supports the panel) is an extruded aluminum framework which supports a pair of spaced-apart glass panels above the solar panel. Water in conduits from a system for heating or cooling or both is connected to flow into an inlet and discharge from outlet of a finned coil received within the heat exchanger. The collector panel provides heat during the day through desorption and condensing of water vapor from the heated solar panel in the heat exchanger and cools at night by the re-adsorption of the water vapor from the heat exchanger which lowers the absolute pressure within the system and cools the heat exchange coils by evaporation.

MULTI-WAVELENGTH OBSERVATIONS OF THE SPATIO-TEMPORAL EVOLUTION OF SOLAR FLARES WITH AIA/SDO. I. UNIVERSAL SCALING LAWS OF SPACE AND TIME PARAMETERS  

SciTech Connect (OSTI)

We extend a previous statistical solar flare study of 155 GOES M- and X-class flares observed with AIA/SDO to all seven coronal wavelengths (94, 131, 171, 193, 211, 304, and 335 ) to test the wavelength dependence of scaling laws and statistical distributions. Except for the 171 and 193 wavelengths, which are affected by EUV dimming caused by coronal mass ejections (CMEs), we find near-identical size distributions of geometric (lengths L, flare areas A, volumes V, and fractal dimension D{sub 2}), temporal (flare durations T), and spatio-temporal parameters (diffusion coefficient ?, spreading exponent ?, and maximum expansion velocities v{sub max}) in different wavelengths, which are consistent with the universal predictions of the fractal-diffusive avalanche model of a slowly driven, self-organized criticality (FD-SOC) system, i.e., N(L)?L {sup 3}, N(A)?A {sup 2}, N(V)?V {sup 5/3}, N(T)?T {sup 2}, and D{sub 2} = 3/2, for a Euclidean dimension d = 3. Empirically, we find also a new strong correlation ??L {sup 0.940.01} and the three-parameter scaling law L?? T {sup 0.1}, which is more consistent with the logistic-growth model than with classical diffusion. The findings suggest long-range correlation lengths in the FD-SOC system that operate in the vicinity of a critical state, which could be used for predictions of individual extreme events. We find also that eruptive flares (with accompanying CMEs) have larger volumes V, longer flare durations T, higher EUV and soft X-ray fluxes, and somewhat larger diffusion coefficients ? than confined flares (without CMEs)

Solar Neutrinos  

DOE R&D Accomplishments [OSTI]

The prospect of studying the solar energy generation process directly by observing the solar neutrino radiation has been discussed for many years. The main difficulty with this approach is that the sun emits predominantly low energy neutrinos, and detectors for observing low fluxes of low energy neutrinos have not been developed. However, experimental techniques have been developed for observing neutrinos, and one can foresee that in the near future these techniques will be improved sufficiently in sensitivity to observe solar neutrinos. At the present several experiments are being designed and hopefully will be operating in the next year or so. We will discuss an experiment based upon a neutrino capture reaction that is the inverse of the electron-capture radioactive decay of argon-37. The method depends upon exposing a large volume of a chlorine compound, removing the radioactive argon-37 and observing the characteristic decay in a small low-level counter.

FEMP-FS--Solar Ventilation Preheating  

Broader source: Energy.gov (indexed) [DOE]

Installing a "solar wall" to heat air before it enters a Installing a "solar wall" to heat air before it enters a building, called solar ventilation preheating, is one of the most efficient ways of reducing energy costs using clean and renewable energy. The system works by heating outside air with a south-facing solar collector-a dark-colored wall made of sheet metal and perforated with tiny holes. Outdoor air is drawn through the holes and heated as it absorbs the wall's warmth. The warm air rises in the space between the solar wall and the building wall and is moved into the air-duct system, usually by means of a fan, to heat the building. Any additional heating needed at night or on cloudy days is supplied by the build- ing's conventional heating system. During summer months, intake air bypasses the solar collector,

The Application of Traits-Based Assessment Approaches to Estimate the Effects of Hydroelectric Turbine Passage on Fish Populations  

SciTech Connect (OSTI)

One of the most important environmental issues facing the hydropower industry is the adverse impact of hydroelectric projects on downstream fish passage. Fish that migrate long distances as part of their life cycle include not only important diadromous species (such as salmon, shads, and eels) but also strictly freshwater species. The hydropower reservoirs that downstream-moving fish encounter differ greatly from free-flowing rivers. Many of the environmental changes that occur in a reservoir (altered water temperature and transparency, decreased flow velocities, increased predation) can reduce survival. Upon reaching the dam, downstream-migrating fish may suffer increased mortality as they pass through the turbines, spillways and other bypasses, or turbulent tailraces. Downstream from the dam, insufficient environmental flow releases may slow downstream fish passage rates or decrease survival. There is a need to refine our understanding of the relative importance of causative factors that contribute to turbine passage mortality (e.g., strike, pressure changes, turbulence) so that turbine design efforts can focus on mitigating the most damaging components. Further, present knowledge of the effectiveness of turbine improvements is based on studies of only a few species (mainly salmon and American shad). These data may not be representative of turbine passage effects for the hundreds of other fish species that are susceptible to downstream passage at hydroelectric projects. For example, there are over 900 species of fish in the United States. In Brazil there are an estimated 3,000 freshwater fish species, of which 30% are believed to be migratory (Viana et al. 2011). Worldwide, there are some 14,000 freshwater fish species (Magurran 2009), of which significant numbers are susceptible to hydropower impacts. By comparison, in a compilation of fish entrainment and turbine survival studies from over 100 hydroelectric projects in the United States, Winchell et al. (2000) found useful turbine passage survival data for only 30 species. Tests of advanced hydropower turbines have been limited to seven species - Chinook and coho salmon, rainbow trout, alewife, eel, smallmouth bass, and white sturgeon. We are investigating possible approaches for extending experimental results from the few tested fish species to predict turbine passage survival of other, untested species (Cada and Richmond 2011). In this report, we define the causes of injury and mortality to fish tested in laboratory and field studies, based on fish body shape and size, internal and external morphology, and physiology. We have begun to group the large numbers of unstudied species into a small number of categories, e.g., based on phylogenetic relationships or ecological similarities (guilds), so that subsequent studies of a few representative species (potentially including species-specific Biological Index Testing) would yield useful information about the overall fish community. This initial effort focused on modifying approaches that are used in the environmental toxicology field to estimate the toxicity of substances to untested species. Such techniques as the development of species sensitivity distributions (SSDs) and Interspecies Correlation Estimation (ICE) models rely on a considerable amount of data to establish the species-toxicity relationships that can be extended to other organisms. There are far fewer studies of turbine passage stresses from which to derive the turbine passage equivalent of LC{sub 50} values. Whereas the SSD and ICE approaches are useful analogues to predicting turbine passage injury and mortality, too few data are available to support their application without some form of modification or simplification. In this report we explore the potential application of a newer, related technique, the Traits-Based Assessment (TBA), to the prediction of downstream passage mortality at hydropower projects.

ASYMMETRIC SOLAR WIND ELECTRON DISTRIBUTIONS  

SciTech Connect (OSTI)

The present paper provides a possible explanation for the solar wind electron velocity distribution functions possessing asymmetric energetic tails. By numerically solving the electrostatic weak turbulence equations that involve nonlinear interactions among electrons, Langmuir waves, and ion-sound waves, it is shown that different ratios of ion-to-electron temperatures lead to the generation of varying degrees of asymmetric tails. The present finding may be applicable to observations in the solar wind near 1 AU and in other regions of the heliosphere and interplanetary space.

Reducing the Impacts of Hydroelectric Dams on Juvenile Anadromous Fishes: Bioengineering Evaluations Using Acoustic Imaging in the Columbia River, USA  

SciTech Connect (OSTI)

Dams impact the survival of juvenile anadromous fishes by obstructing migration corridors, lowering water quality, delaying migrations, and entraining fish in turbine discharge. To reduce these impacts, structural and operational modifications to dams such as voluntary spill discharge, turbine intake guidance screens, and surface flow outletsare instituted. Over the last six years, we have used acoustic imaging technology to evaluate the effects of these modifications on fish behavior, passage rates, entrainment zones, and fish/flow relationships at hydroelectric projects on the Columbia River. The imaging technique has evolved from studies documenting simple movement patterns to automated tracking of images to merging and analysis with concurrent hydraulic data. This chapter chronicles this evolution and shows how the information gleaned from the scientific evaluations has been applied to improve passage conditions for juvenile salmonids. We present data from Bonneville and The Dalles dams that document fish behavior and entrainment zones at sluiceway outlets (14 to 142 m3/s), fish passage rates through a gap at a turbine intake screen, and the relationship between fish swimming effort and hydraulic conditions. Dam operators and fisheries managers have applied these data to support decisions on operational and structural changes to the dams for the benefit of anadromous fish populations in the Columbia River basin.

Analysis of legal obstacles and incentives to the development of low-head hydroelectric power in Maine  

SciTech Connect (OSTI)

The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level in Maine is discussed. The Federal government also exercises extensive regulatory authority in the area. The dual regulatory system is examined. The first step any developer of small-scale hydropower must take is to acquire right, title, or interest in the real property. In Maine, that step requires acquisition in some form of both river banks, the river bed, and where necessary, the land needed for the upstream impoundment area. The developer must acquire the river banks to be considered a riparian owner. Classification as a riparian is important, for only a use of water by a riparian owner is deemed a reasonable use and hence a legal use. A non-riparian could not draw water from a stream to increase the water level of an impoundment area on another stream. Apart from the usual methods of land acquisition involving sale, lease, or perhaps gift, Maine has two somewhat unique methods a developer may use for property acquisition. These methods, authorized by statute, are use of the abandoned dams law and use of the Mill Dam Act for flowage of upstream impoundment areas.

Solar Neutrinos  

E-Print Network [OSTI]

Experimental work with solar neutrinos has illuminated the properties of neutrinos and tested models of how the sun produces its energy. Three experiments continue to take data, and at least seven are in various stages of planning or construction. In this review, the current experimental status is summarized, and future directions explored with a focus on the effects of a non-zero theta-13 and the interesting possibility of directly testing the luminosity constraint. Such a confrontation at the few-percent level would provide a prediction of the solar irradiance tens of thousands of years in the future for comparison with the present-day irradiance. A model-independent analysis of existing low-energy data shows good agreement between the neutrino and electromagnetic luminosities at the +/- 20 % level.

Solar collector  

SciTech Connect (OSTI)

The disclosure is a solar collector consisting of glass rods enclosed in a housing and mounted vertically on a roof or other elevated place to gather solar rays. The collector is fixed, with no tracking device or other moving parts. The glass rods are 6 mm or smaller in diameter, and there can be several thousand, depending on the sizes of the rods and collector. The upper ends of the rods are inclined at an angle of thirty degrees from horizontal, with the inclined surfaces occupying a plane which faces south so as to obtain maximum exposure to the winter sun. Solar rays striking the inclined ends of the rods are refracted into the rods. The rays travel down through the rods, with a predominantly parallel path of propagation being established by repeated reflections off the inside walls of the rods. The rays are emitted from the lower perpendicular ends of the rods as parallel rays of incoherent light which are directed into beam concentrators.

Annual measured performance of building-integrated solar energy systems in demonstration low-energy solar house  

Science Journals Connector (OSTI)

This paper presents the details of the output and efficiency of the annual performance of building-integrated solar energy systems for a solar water heating system and solar photovoltaic (PV) modules of a demonstration near-zero-energy solar house that was constructed on the campus of the Korea Institute of Energy Research. The thermal systems installed in the house were a solar water heating system with building-integrated solar collectors for water heating and for part of the space heating and a ground-coupled heat pump for space cooling and part of the space heating. Solar PV modules were installed on the roof of the house. The performance of these systems was monitored for more than 1 yr. The annual efficiencies of the building's integrated solar collectors and solar PV were 22.8% and 10.9% respectively. The total annual solar fraction of the solar heating system was 69.7% with an annual solar heat production of 248?kW h/m2. This paper also focuses on the efficiency of the house's solar storage based upon intentionally varied drainage of hot water from the storage tank. It was found that the thermal loss from the solar storage tank has a strong functional relationship with the thermal demand of the solar storage tank per unit volume. For example when the hot water consumption was reduced by half during September the thermal loss increased to more than 70% which would otherwise have been around 30%.

Active noise within the generating/pumping groups of a large hydroelectric plant  

Science Journals Connector (OSTI)

This work is related to a feasibility study for the implementation of an active noise control system to reduce the hydraulic turbomachines noise in the Presenzano power plant. Previous studies showed that interested turbines are low frequencies noise sources generating pure tones at 150 and 200 Hz (third and fourth harmonics of the turbines BPF). At these frequencies passive noise control systems are ineffective in front of relevant costs and an active approach was so decided to be tested. In accordance with a classical architecture the preliminary system was composed of four error microphones four secondary noise sources and a digital controller implementing an adaptive digital filter. Main performed activities could be identified through four successive steps: (i) analysis of the turbomachines generated primary field levels and space distribution (ii) secondary sources generated noise field measurement ten different loudspeakers locations were investigated at this stage; (iii) sensor and actuator locations optimization by the use of a genetic algorithms procedure and (iv) active noise control tests. A mean reduction of 15 dB at 150 Hz and 7.5 dB at 200 Hz was measured at the error sensors during these tests revealing the good opportunities of such an approach but also the opportune improvement to pass at a practical implementation.

Solar Photovoltaic Technology Basics Solar Photovoltaic Technology Basics Content on this page requires a newer version of Adobe Flash Player. Get Adobe Flash player This video provides an overview of NREL's research in solar photovoltaic technology. Text Version Solar cells, also called photovoltaic (PV) cells by scientists, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect. The PV effect was discovered in 1954, when scientists at Bell Telephone discovered that silicon (an element found in sand) created an electric charge when exposed to sunlight. Soon solar cells were being used to power space satellites and smaller items like calculators and watches. Today, thousands of people power their homes and businesses with individual

Solar neutrinos and the solar composition problem  

E-Print Network [OSTI]

Standard solar models (SSM) are facing nowadays a new puzzle: the solar composition problem. New determinations of solar metal abundances lead SSM calculations to conflict with helioseismological measurements, showing discrepancies that extend from the convection zone to the solar core and can not be easily assigned to deficiencies in the modelling of the solar convection zone. We present updated solar neutrino fluxes and uncertainties for two SSM with high (old) and low (new) solar metallicity determinations. The uncertainties in iron and carbon abundances are the largest contribution to the uncertainties of the solar neutrino fluxes. The uncertainty on the ^14N+p -> ^15O+g rate is the largest of the non-composition uncertainties to the CNO neutrino fluxes. We propose an independent method to help identify which SSM is the correct one. Present neutrino data can not distinguish the solar neutrino predictions of both models but ongoing measurements can help to solve the puzzle.

Si concentrator solar cell development. [Final report  

SciTech Connect (OSTI)

This is the final report of a program to develop a commercial, high-efficiency, low-cost concentrator solar cell compatible with Spectrolab`s existing manufacturing infrastructure for space solar cells. The period covered is between 1991 and 1993. The program was funded through Sandia National Laboratories through the DOE concentrator initiative and, was also cost shared by Spectrolab. As a result of this program, Spectrolab implemented solar cells achieving an efficiency of over 19% at 200 to 300X concentration. The cells are compatible with DOE guidelines for a cell price necessary to achieve a cost of electricity of 12 cents a kilowatthour.

U.S. Solar Market Trends  

SciTech Connect (OSTI)

U.S. solar installations by technology are detailed for 1998???¢????????2005. The growth and state distribution of installations are different for the three primary solar sectors: ???¢???????¢ photovoltaics, ???¢???????¢ solar water heating and space heating, and ???¢???????¢ solar pool heating. Photovoltaic installations have grown steadily. Since 2001, grid-connected installations grew at an average rate of 52%. California has 79% of the installations, with Arizona, New Jersey, New York, Illinois, Massachusetts, and Oregon accounting for most of the remaining installations. The offgrid growth has been steady, but significantly lower. Solar water heating and solar space heating installations have shown little growth since 1997. Hawaii dominates, with 41% of the market. Other states with a large number of installations include Puerto Rico, California, Florida, and Arizona. Solar pool heating accounts for the largest number of installations and has grown at an average rate of 13% since 1997. Installations in California and Florida are 75% of the pool heating market.
