  2. 1. Steam Turbine Optimisation for Solar Thermal Power Plant Operation

    Author : James Spelling; Andrew Martin; Magnus Genrup; KTH; []
    Keywords : solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Abstract : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. READ MORE

  4. 2. Dynamic Thermal Rating for Improved Utilization of Wind Farm Export Systems : A Methodology for Improving Load Profile Estimation of Wind Farm Export Transformers

    Author : Zhongtian Li; Patrik Hilber; Tor Laneryd; Stefan Ivanell; Nguyen Nga; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic thermal rating; wake effect; turbine availability; transformer lifetime; transformer aging; dynamisk termisk klassificering; väckningseffekt; turbintillgänglighet; transformatorlivslängd; transformatoråldring; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The power system components connected to renewable energy sources, such as transformers, are often oversized and conservatively loaded. The design of transformers normally ignores the intermittent nature of the connected renewable energy sources (e.g. solar, wind). READ MORE

  5. 3. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

    Author : Joachim Härsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

    Abstract : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. READ MORE

  6. 4. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Author : Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Keywords : Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Abstract : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. READ MORE

  7. 5. Design of Internal Cooling Passages: Investigation of Thermal Performance of Serpentine Passages

    Author : Waseem Siddique; Torsten Fransson; Bengt Sundén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; heat transfer; CFD; Serpentine passages; SRA - Energy; SRA - Energi;

    Abstract : Gas turbines are used to convert thermal energy into mechanical energy. The thermal efficiency of the gas turbine is directly related to the turbine inlet temperature. READ MORE
