    Nyckelord :solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Sammanfattning : 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. LÄS MER

  2. 2. On Degradation and Monitoring Tools for Gas and Steam Turbines

    Författare :Magnus Genrup; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Throughflow; Thermal engineering; Monitoring; Gas Turbine; Turbomachinery; termodynamik; Termisk teknik; Deterioration; Steam Turbine;

    Sammanfattning : The revenue from a power plant is strongly dependent on the life cycle cost. Today, when the market conditions for power-producing companies have shifted from a protected market to a deregulated market, the need for tools to monitor power plants has increased significantly.

    Sammanfattning : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. LÄS MER

  5. 5. Improving Concentrating Solar Power Plant Performance through Steam Turbine Flexibility

    Författare :Monika Topel; Björn Laumert; Markus Jöcker; Magnus Genrup; Tony Arts; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating Solar Power; Steam Turbines; Transients; Start-up; Energy Technology; Energiteknik;

    Sammanfattning : The amount of incoming solar energy to earth is greater than any other source. Among existing technologies to harness solar energy there is concentrating solar power (CSP). One advantage of CSP is that is dispatchable, meaning that it can provide power even when the sun is not shining. LÄS MER
