The simulation model of the marine electric propulsion system was built by means of MATLAB/Simulink software.The process and method of the principle and implementation of synchronization,along with the key techniques such as power allocation and frequency adjustment of synchronization,were analyzed based on the speed control characteristics of the diesel generators,resulting in the synchronization and power control of different types of the diesel generators.The synchronization simulation was designed according to the navigation demand of the vessel and both grid voltage and current characteristics,and the parameters changing characteristics of the generators in the synchronization process were analyzed,which might serve as reference for the proposal design of the diesel generator selection and the control methods of electric propulsion system.
