摘　　要：随着舰船综合电力系统的发展,可通过舰船动力调度中心控制逆变器和船舶辅助发电机并网,以保证舰船低压设备的供电。在舰船综合电力系统的逆变器、交流发电机并网过程中,为确保舰船低压电网在电源切换过程中的稳定性,该文提出逆变器控制模式切换与辅助发电机同期并网相结合的控制策略,通过能量管理系统对逆变器、发电机进行控制,解决了船用逆变器与辅助发电机并网过程的稳定控制与功率分配问题。通过1∶1样机物理实验,验证了该控制策略的有效性与可靠性。With the development of the ship's integrated power system,the power supply of low-voltage equipment can be guaranteed through connecting the inverter and the auxiliary generator of the ship by the ship power dispatching center.In order to ensure the stability of low-voltage power grid during the power supply switching process,the inverter and alternator of the ship's integrated power system are connected to the grid.Combined with the control strategy,the inverter and generator are controlled through the energy management system,which solves the problem of stable control and power distribution in the process of connecting the marine inverter with the auxiliary generator.Through the 1∶1 prototype physical experiment,the effectiveness and reliability of the control strategy are verified.
