1. 1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Sanger Shinwari; [2023]
   Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

   Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

3. 2. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Daniel Almailea; [2023]
   Nyckelord :Gas Turbines; Synchronous Machines; Generators; Turbogenerators; Fault Ride Through FRT ; Low Voltage Ride Through LVRT ; Grid Codes; Frequency; Inertia; Generator Inertia; Power System; MATLAB; Simulink; Modeling; Excitation System; Automatic Voltage Regulator AVR ; Saturation Curve; Capability Curve; Load Angle; Siemens Energy.;

   Sammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER

4. 3. Aerothermal and Kinetic Modelling of a Gas Turbine Dry Low Emission Combustion System

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :David Håkansson; [2021]
   Nyckelord :Gas turbine; combustion; one-dimensional combustion simulation; network model; general network model; NOx emissions; hydrogen; Gasturbin; förbränning; endimensionell förbränningssimulering; nätverksmodell; generell nätverksmodell; NOx-utsläpp; väte;

   Sammanfattning : Growing environmental concerns are causing a large transformation within the energy industry. Within the gas turbine industry, there is a large drive to develop improved modern dry-low emission combustion systems. The aim is to enable gas turbines to run on green fuels like hydrogen, while still keeping emission as NOx down. LÄS MER

5. 4. Transient Performance of Siemens SGT-750 and SGT-800 : Modeling and Simulations of Industrial Gas Turbines on Island Grids

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Alexander Raddum; [2020]
   Nyckelord :Gas Turbine; Transients; Simulation;

   Sammanfattning : Distributed energy production in the form of renewable energy sources are expected to increase in the coming years, a consequence of this is instability of the power grids due to the stochastic nature and lack of inertia of renewable energy sources. In addition, small and local, so called island grids, are on the rise and these system may present an even higher sensitivity to frequency fluctuations. LÄS MER

7. 5. Frequency Simulation at Island Grid Operation of a SGT-800 Gas Turbine

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Viktor Kasimir; [2020]
   Nyckelord :;

   Sammanfattning : A frequency simulation for island grid operation of a SGT-800 gas turbine has been developed using the swing equation derived for synchronous machines. With the ever expanding and changing power grid, the requirements for plants to comply with grid code is getting more strict. LÄS MER
