  3. 2. 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

  4. 3. Gas Turbine Plant Modeling for Dynamic Simulation

    Sammanfattning : Gas turbines have become effective in industrial applications for electric and thermal energy production partly due to their quick response to load variations. A gas turbine power plant is a complex assembly of a varietyof components that are designed on the basis of aero thermodynamiclaws. LÄS MER
