| 摘要: |
| 针对船舶岸电一体化系统岸电接入时，船岸两侧电力系统的差异以及船舶负荷无缝切换的需求，提出了基于并网过程多时段划分的船舶岸电并网功率波动平抑策略，对合闸前、合闸时、合闸后、柴油发电机退出运行时间段分别提出针对性的控制策略，并结合综合能量管理系统(IEMS)的协同管理条件抑制在并网及负荷转供过程中出现的功率波动值，保护船岸两侧配、用电设备。仿真结果表明，所提策略能够实现岸船两侧电力系统的跟踪控制，并在保证负荷不间断供电的前提下完成变频电源分时段控制模式之间的平滑切换，达到了并网功率波动平抑的目的。 |

| Abstract: |
| Aiming at the difference between electric power system of shore and ship sides and the demand of seamless switching of ship load in the process of shore electricity accessing in the ship-shore integrated system, a suppression strategy of grid-connected power fluctuation in shore-to-ship power system is proposed based on the multi-period division of the grid-connected process. The target control strategies are respectively proposed for the period before closing, the moment of closing, the period after closing and the moment that diesel generators quit operation. Combining with the cooperative management conditions of IEMS(Integrated Energy Management System),the power fluctuation in the process of grid connection and load transfer is suppressed, and the distribution and electrical equipment on shore and ship sides are protected. The simulative results show that the proposed strategy can realize the tracking control of the electric power system on shore and ship sides and the smooth switching between multi-period control modes of the variable frequency power supply under the premise of ensuring uninterrupted power supply, and achieve the goal of smoothing the grid-connected power fluctuation. |
