When the ship sails, the propulsion motor had to change different working states to ensure the stable operation of the ship. At the moment of switching the working state, there will be a certain impact on the transient characteristics of ship power system. In this paper, the electric propulsion ship is taken as the research object, the transient fluctuations of system voltage and power during ship acceleration and deceleration are studied by simulation. Based on the simulation results, the flywheel energy storage method is used to improve the transient characteristics of the ship power system. Combined with the flywheel 0d axis control and the charging and discharging control strategy of the flywheel energy storage system, the energy transfer is realized through the bidirectional AC / DC converter. The case analysis result shows that using flywheel energy storage system can improve the transient stability of DC bus voltage of the electric ship propulsion system and to improve the overall transient characteristics of the system.
