摘　　要：针对船舶电动机起动电流达额定电流的6～10倍导致母线电压降低并影响其他电力设备的正常运行及电网稳定的问题,从减小母线电压降的角度,研究了船舶电网中的电动机起动方案。利用EMTP及PSCAD建立船舶仿真系统对各种方案进行了对比分析,可为船舶电动机起动方案的配置提供参考。The starting current of motor in shipping attains as much as 6-10 times rated current and it may lead to bus voltage drop and affect normal operation of other devices and safety of system.From the aspect of reducing bus voltage drop,different starting methods of induction motor in shipping power system are simulated by using EMTP and PSCAD.In accordance with that,their performance are analyzed and compared in detail.Therefore,it provides reference for configuration schemes of motor starting.
