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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : James Spelling; KTH.; [2011]
    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

  2. 2. Steam Turbine Thermal Modeling for Improved Transient Operation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Monika Topel; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam turbines; transients; start-up; finite element model; heat transfer; Energiteknik; Energy Technology;

    Abstract : The growing shares of renewable energy sources in the market and solar thermal power applications have set higher requirements on steam turbine operation.These requirements are related to flexibility during transients. A key aspect sought of such flexibility is the capability for fast starts. READ MORE

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

    University dissertation from KTH Royal Institute of Technology

    Author : Monika Topel; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating Solar Power; Steam Turbines; Transients; Start-up; Energiteknik; Energy Technology;

    Abstract : 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. READ MORE

  4. 4. Improved Flutter Prediction for Turbomachinery Blades with Tip Clearance Flows

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Tianrui Sun; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam turbine; Flutter; Aeroelastic stability; Tip clearance flow; Detached-Eddy Simulation; Energiteknik; Energy Technology;

    Abstract : Recent design trends in steam turbines strive for high aerodynamic loading and high aspect ratio to meet the demand of higher efficiency. These design trends together with the low structural frequency in last stage steam turbines increase the susceptibility of the turbine blades to flutter. READ MORE

  5. 5. Improved Steam Turbine Design for Optimum Efficiency and Reduced Cost of Ownership

    University dissertation from Department of Energy Sciences, Lund University

    Author : Srikanth Deshpande; Lund University.; Lunds universitet.; [2017-04-02]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The cost of ownership of a power plant is partly governed by the efficiency of the turbine island. The turbine stands for the production revenues when transforming the energy in fuel into electric power and district heating. READ MORE
