1. 1. Automated High-Temperature Pressure Sensor Verification and Characterization

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Algirdas Bartkevicius; [2023]
   Keywords : Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

   Abstract : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. READ MORE

3. 2. 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

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

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

   Abstract : 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. READ MORE

4. 3. 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

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Daniel Almailea; [2023]
   Keywords : 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.;

   Abstract : 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. READ MORE

5. 4. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Jean-Pierre Hamzo; [2023]
   Keywords : CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

   Abstract : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. READ MORE

6. 5. Assessing the Benefits of Fossil-Free Gas Turbines in Distribution Networks : A Case Study in Västerås

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

   Author : Fredrik Hansell; Axel Vällfors; [2023]
   Keywords : Gas turbine; power system stability; balancing markets; hydrogen; eMethanol; Gasturbin; kraftsystemstabilitet; balansmarknader; vätgas; e-metanol;

   Abstract : As the share of weather-dependent renewable electricity production increases, the demand for power system flexibility grows. In the Swedish power system, gas turbines have historically been utilised for back-up power generation. READ MORE
