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. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Nikolaos Bozikis; [2022]
   Nyckelord :Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

   Sammanfattning : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. LÄS MER

4. 3. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Johan Hansson; [2020]
   Nyckelord :Machine Learning; Vibrations;

   Sammanfattning : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. 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
