The Control and Modeling of Diesel Generator Set in Electric Propulsion Ship

This paper analyzes the characteristics of power system on electric propulsion ship. The mathematical model and simulation model of diesel engine PID speed control system and synchronous generator’s AVR+PSS excitation control system was built. At last the simulation test of suddenly add load was did in MATLAB/simulink environment. The result shows that the speed control and excitation control system has well stability, rapidity and some robustness.
