  1. 21. Network Programming Applied too Operation Planning of Hydrothermal Power Systems

    Författare :Håkan Brännlund; Janis Bubenko; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Network programming; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The objective of the project was to develop models and methods suitable for computer implementation. In particular, this work has been devoted to generation scheduling of a power system with a sizeable amount. of hydro energy. LÄS MER

  3. 22. 14C Produced by Nuclear Power Reactors - Generation and Characterization of Gaseous, Liquid and Solid Waste

    Författare :Åsa Magnusson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; waste disposal; spent ion-exchange resins; mass balance assessment; Nuclear physics; environmental impact; Fysicumarkivet A:2007:Magnusson; nuclear power plant; Kärnfysik; Carbon-14;

    Sammanfattning : This thesis presents the results from studies on carbon-14 produced by nuclear power reactors. Radioactive 14C enters the carbon cycle and can be taken up by humans, where it will constitute a potential health hazard. LÄS MER

  4. 23. Humidification in Evaporative Power Cycles

    Författare :Farnosh Dalili; KTH; []
    Nyckelord :Gas Turbines; EvGT; HAT; Humidification; Evaporator; Saturator;

    Sammanfattning : Evaporative gas turbine cycles (EvGT) show an exceptionalexhaust heat recovery potential, which makes them a strongcompetitor to other advanced gas turbine cycles, especiallyfrom small to intermediate sizes. Evaporative gas turbines aredistinguished by humidifying the working fluid beforecombustion at temperatures below the boiling point of water;and the heat required for evaporation of water is partly takenout of the exhaust gas.

  5. 24. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

    Författare :Nilsson Olof; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... LÄS MER

  7. 25. Ammonia as an Absorbent of Carbon Dioxide in Post-Combustion Capture - an Experimental, Technical and Economic Process Evaluation

    Författare :Henrik Jilvero; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost of capture; carbon dioxide; carbon capture; power plant; ammonia; process simulations;

    Sammanfattning : Carbon capture and storage is vital to facilitating the transition from our current fossil fuel-based energy system to a sustainable energy system. The concept of post-combustion capture is based on the selective chemical absorption of carbon dioxide (CO2). LÄS MER
