Modeling and simulation of Bazyan Gas Power Plant

The aim of this thesis is to investigate the modeling and simulation of the Bazyan gas power plant (BGPP). The demand for energy in the developing regions of the world has shown a clear increase in the recent past. Therefore, it is important to use power generations that have high efficiency and specific power output, low pollutant emissions and low operating and maintenance costs for possible use of available fuels. Industrial gas turbines are one of the established technologies for power generation. Power supply systems require the exact models of energy system elements. Exciter, speed control and gas turbine are important components of the production units. First, each part of the turbine is described by its transfer function, and then the block model is thoroughly built. In addition to the turbine, the IEEE AC7B excitation system with an Power system stabilizer (PSS2B), a synchronous generator and a transformer are considered in simulation studies. This model is then adapted to the newly installed gas power plant in the north of Iraq, called Bazyan Gas Power Plant (BGPP), using real data from the data sheets of the BGPP manufacturers. For the simulation, the station is connected to a load. Simulation studies are carried out under small signal disturbances, For example, a unit-step controller change, as well as large disturbing conditions such as ground fault and three phase faults. In each step, various system variables such as rotor angle, acceleration power, connection voltage and rotor speed are recorded and plotted.
