Abstract


With the ship integrated power system has become the future development direction of ship power system; gas turbine is the ideal choice for the power generation module prime mover because of its unique advantages. In this paper, simulating the operating characteristics and mutation load control characteristics of a certain type three-axis gas turbine as power generation module prime mover.The paper is based on a certain type of three-axis gas turbine electric propulsion as the original motivation of integrated electric propulsion, using modular modeling idea to establish the nonlinear model of gas turbine system major components, while taking into account the inertia of the rotor inertia and volume, the model has good versatility. Using neural networks to handle the compressor and turbine components characteristic curve, verified with high accuracy. Using Matlab/Simulink, this work established a gas turbine power generation module. Reference to gas turbine operating characteristics relevant information, respectively initially setting gas turbine rated power, gas turbine power generation module fault protection, high pressure compressor tail discharge air, the governor setting, PID control parameters, minimum, maximum fuel flow restrictions and other parameters of gas turbine power generation module.According to the mutation load requirements of gas turbine power generation module, Respectively designed PID control system and fuzzy PID control system,and simulating gas turbine power generation module load sudden decrease 20%; load sudden decrease 40%;load sudden decrease 60%; load sudden decrease 100% and load sudden decrease 50% .The simulation results show that when gas turbine power generation module mutation load, set down parameter and design PID control system and fuzzy control system can make it meet guide line. Through comparing simulation results,When load sudden decrease 40%,60% and 100%,fuzzy PID control system is better than PID control system.The simulation of gas turbines for power generation module of the original motivation can be used as references to the gas turbine power generation mode.
