Performance Simulation of Natural Gas Supply System of a Heavy Duty Gas Turbine

Abstract

Abstract: Abstract： The performance of the natural gas supply system has a great influence on the performance of the heavy duty gas turbine. Therefore, the modeling and simulation approach was used to study the performance of the natural gas supply system. First, the main components of the system were modeled based on the modular modeling concept. Next, according to the practical operation data provided by power plants, the setting criterion of pressure and pilot gas/premix gas flow were analyzed by BP neural network. Finally, the pressure, temperature and flow controller based on PID principle were added to the whole simulation model. The steady simulation and dynamic simulation were both implemented in this simulation model. The simulation results approximately conform to the practical operating data, indicating that the model can accurately describe the whole performance of the natural gas supply system.
