摘要
针对船舶靠港使用岸电易发生全船失电的故障和逆变器的动态响应过快影响船舶电网稳定性的问题,基于下垂控制策略建立船舶与岸电无缝并网控制系统,在下垂控制器中加入虚拟惯性环节,优化控制策略,仿真实验结果表明,所搭建的控制系统能够实现船舶供电电源的无缝切换,控制策略的优化方案可改善逆变器的动态响应性能,提高电网的稳定性。
In view of the shipping port to use shore power easy to have the ship lost power failure and the dynamic response of the inverter too problems,which influence the stability of ship power grid based on the droop control strategy to build ship and shore power seamless interconnection control system,and to join in the droop controllers virtual inertia link,optimizing control strategy.The simulation results indicate that the control system can realize the seamless switch of the ship power supply.The optimization scheme of control strategy improves the dynamic response performance of the inverter and improves the stability of the power grid.
