1. 1. Development and validation of a combined heat and power plant model for integration in DYESOPT

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : José Angel García; [2018]
   Keywords : ;

   Abstract : The liberalization of electricity markets and a growing penetration of renewables has led many countries to feel changes in the operation of their grids. The boundary conditions for the operation of conventional power plants are changing and, as such, an improved understanding of the varying loads and prices on the electricity grid is required to assess the performance of emerging combined cycle gas turbine (CCGT) concepts and to further optimize their design for these new markets in the pursuit of increasing their profitability, especially when considering co-generation of heat and power.

3. 2. Nonlinear Model Predictive Control for Combined Cycle Power Plants

   University essay from Lunds universitet/Institutionen för reglerteknik

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

   Abstract : 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. READ MORE

4. 3. Development of a tool for simulating performance of sub systems of a combined cycle power plant

   University essay from KTH/Energiteknik

   Author : Prabodha Jayasinghe; [2012]
   Keywords : Heat rate; Power plant efficiency; Gas turbine efficiency; Steam turbine efficiency;

   Abstract : 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. READ MORE

5. 4. Simulation of Heat Recovery Steam Generator in a Combined Cycle Power Plant

   University essay from Institutionen för systemteknik; Tekniska högskolan

   Author : Kristofer Horkeby; [2012]
   Keywords : Modelling and Simulation; Control System; Combined-Cycle Power Plant; Heat Recovery Steam Generator; Dymola; Modelica; Siemens;

   Abstract : This thesis covers the modelling of a Heat Recovery Steam Generator (HRSG) in a Combined Cycle Power Plant(CCPP). This kind of power plant has become more and more utilized because of its high efficiency and low emissions. The HRSG plays a central role in the generation of steam using the exhaust heat from the gas turbine. READ MORE

6. 5. Waste Heat Recovery Modellering

   University essay from KTH/Förbränningsmotorteknik

   Author : Fernando Rojas Tena; Reber Kadir; [2011]
   Keywords : ;

   Abstract : SammanfattningI ett tidigare projekt, utfört under våren 2010, modellerades och simulerades en ånggenerator i GT-SUITE för att analysera och jämföra dess resultat med de faktiska motormätningarna. Projektet utfördes på Kungliga Tekniska Högskolan i Stockholm, på uppdrag av företaget som introducerat idén, Ranotor. READ MORE
