In order to increase overall performance of the shaft generator system, a new type marine shaft generator system with PWM inverter is discussed in the paper The virtual synchronous generator control algorithm is adopted to achieve the frequency-active power and voltage-reactive power droop characteristics, which are similar with the diesel generator system. The simulation model of the new shaft generator system is built in MATLAB/Simulink, and the control algorithm is verified to support its correctness and effectiveness used on the ships.
