以全电力推进船舶为研究对象，针对船上其他用电设备的功耗波动对电力系统的影响这一实际情况，在不影响定位功能的前提下，在原有的推力分配基础上研究具有功率管理功能的推力分配策略，采用基于动态负载控制法的推力分配方法，以达到减小电网总功耗波动和提高船舶电力系统稳定性的目标。仿真验证此方法导致的船舶在速度和位置上的偏差被成功地限制在一定范围内，也证明了如此小的偏差足以实现减小电网功耗波动的目标。
For the problem that power variation of other consumers on vessels causes serious impact on electric power system, under the premise of not affecting the positioning function, taking all electric propulsion vessels as the research object, this paper studies thrust allocation strategies with the function of power management based on original thrust allocation, and takes dynamic load control method to reduce total power fluctuation of power grid and improve the stability of electric power system. The simulation proves that the deviation on velocity and position of vessel caused by the way can be restricted to a certain extent successfully and such deviation can realize the target that reducing power fluctuation of power grid.
