  1. 1. Derivation of a correlation to determine a combined cycle's performance based on data from the gas turbine exhaust

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ingelström; [2019]
    Nyckelord :Combined Cycle efficiency; second law efficiency; HRSG; exergy; irreversibilities; Technology and Engineering;

    Sammanfattning : Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. LÄS MER

  3. 2. Relating gas turbine performance to combined cycle efficiency

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Simon Frick; [2018]
    Nyckelord :combined cycle efficiency; second law efficiency; exergy; HRSG; irreversibility; heat engine; thermodynamics; T-q diagram; Technology and Engineering;

    Sammanfattning : The gas turbine has been around for over a century, providing power for a variety of applications. The efficiency, i.e. the amount of power produced per kilogram of fuel provided, has increased steadily over the years and is today greater than 44 percent in a state of the art gas turbine. LÄS MER

  5. 4. Nonlinear Model Predictive Control for Combined Cycle Power Plants

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Anna Johnsson; [2013]
    Nyckelord :Optimization; Nonlinear Model Predictive Control; Extended Kalman lter; Modelica; Optimica; JModelica.org; Technology and Engineering;

    Sammanfattning : This master thesis project serves to investigate the possibilities of Nonlinear Model Predictive Control (NMPC) using the example of enthalpy control of the BENSON HRSG (heat recovery steam generator) of a combined cycle power plant (CCPP). The general idea of NMPC is to solve an optimization problem, to nd the next control action, and this optimization problem is based on a model of the system. LÄS MER

  7. 5. Development of a tool for simulating performance of sub systems of a combined cycle power plant

    Master-uppsats, KTH/Energiteknik

    Författare :Prabodha Jayasinghe; [2012]
    Nyckelord :Heat rate; Power plant efficiency; Gas turbine efficiency; Steam turbine efficiency;

    Sammanfattning : Abstract In Sri Lanka, around 50% of the electrical energy generation is done using thermal energy, and hence maintaining generation efficiencies of thermal power plants at an acceptable level is very important from a socio-economic perspective for the economic development of the country. Efficiency monitoring also plays a vital role as it lays the foundation for maintaining and improving of generation efficiency. LÄS MER
