摘要:

针对永磁电机应用于发电系统中所存在的适用转速范围较窄和容错运行可靠性不高的问题,提出了一种基于逆变器–整流器的绕组开路型永磁发电系统。分析了其系统拓扑结构和工作原理,阐述了其发电运行控制策略,并重点分析了电机侧的各种故障状态,提出了相应的故障容错运行控制方法,利用Matlab软件搭建了系统的仿真模型并进行了仿真研究,仿真结果表明,系统在各种故障状态下都能维持一定的发电功率运行,验证了所提出的故障容错运行控制策略的有效性。

Abstract:

Due to the narrow speed range and the poor reliability of fault tolerant for the PMSM applied in generation system, this paper presented a novel open-winding PM generation system based on the inverter-rectifier, the topology and operation principle were analyzed and the control method of proposed system is proposed. Then, the fault tolerant control strategy was given based on the detail analysis of the various fault states and the simulation models were built based by the software of Matlab. The simulation results verify the feasibility of maintain output characteristics under fault conditions and the validity of the proposed control method.

Key words: Open-winding, permanent magnet motor, fault tolerant, inverter-rectifier
