  • The rise of Fresnel technology is heavily aided by the consolidation in the CSP industry

    The need for increasing project scale is driving a round of partnerships and acquisitions that could soon see the CSP industry reduced to a few vertically-integrated monoliths and this could be aiding the raise of the Fresnel technology with AREVA entering strongly this market. In an industry that has seen more than its fair share of mergers and acquisitions in the last couple of years, ...

  • Gorham hydro - Case study

    The Gorham plant is located on the Androscoggin River in Gorham, New Hampshire and is owned and operated by Great Lakes Hydro America, a subsidiary of Brookfield Power. CHC provided three 890 mm replacement Francis runner assemblies as part of the Gorham Hydro upgrade project. Commissioning of the three new turbines was completed in ...

  • Evaluation of Gas Turbine Startup and Shutdown Emissions for New Source Permitting

    Utility deregulation and the increase in electrical demand have led to a surge in new gas turbine-based power projects. This paper examines the regulatory issues relating to startup/shutdown emissions, emissions profiles during gas turbine startups/shutdowns, annual emissions calculations, a methodology for evaluating the air quality impacts of startup emissions, and compliance with emission ...

  • Vector control of current regulated inverter connected to grid for wind energy applications

    Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

  • Tidal influence on offshore wind fields and resource predictions

    The rise and fall of the sea surface due to tides effectively moves an offshore wind turbine hub through the wind shear profile. This effect is quantified using measured data from three offshore UK sites. Statistical evidence of the influence of tide on mean wind speed and turbulence is presented. The implications of this effect for predicting offshore wind resource are outlined.Keywords: Tidal, ...

  • Modelling of the hydro-generator local network operation and load disturbance rejection

    The paper describes models of the local network operation of the hydraulic turbine-generator unit. Two different models are proposed. They describe the dynamic behaviour of a system in which the unit is connected to an equivalent system. A nonlinear model of the interconnection to an equivalent power system is considered. An optimal controller for load disturbance rejection in water turbine speed ...
