摘　　要：针对船舶直流供电系统中500 V的供电要求,研究了以双三相永磁同步发电机为主体的六相可控整流系统,确定基于双d-q变换的双闭环PI解耦控制,在负载和转速发生突变的情况下保证输出的直流电压能迅速恢复到500 V并保持恒定。利用Simulink软件搭建可控整流系统的仿真模型,进行多相可控整流仿真,仿真结果表明了双闭环矢量控制的有效性,该系统有较快的响应速度以及良好的动静态性能。For the requirement of 500 V power supply in marine DC power supply system,a six-phase controlled rectification system with the dual three-phase permanent magnet synchronous generator(PMSG)is studied,and a double closed-loop PI decoupling control method based on double d-q transformation is determined.The output DC voltage can be ensured to restore to 500 V quickly and maintain constant when the load and rotate speed change abruptly.The simulation model of controllable rectification system is built by using Simulink software to perform the multi-phase controlled rectification simulation.The simulation results show the effectiveness of double closed-loop vector control,and the system has fast response speed and good dynamic and static performance.
