摘要
为实现开绕组永磁同步发电机(PMSG)在变流器故障下的容错运行,本文通过分析开绕组PMSG系统变流器存在的故障类型,建立容错故障状态下开绕组PMSG的数学模型,通过研究不同故障状态下两个变流器的电压矢量分布,给出了开绕组PMSG变流器容错运行所需的电压空间矢量分配机制,进而提出每种故障状态下的开绕组PMSG控制策略。最后通过搭建的开绕组永磁电机实验平台,验证了所提出容错运行方案的可行性。
In order to implement the fault-tolerant operation of converter for permanent magnet synchronous generator(PMSG) based on open winding configuration,the paper firstly analyzed the fault types of the converter,and developed the mathematic model of open winding PMSG under the fault tolerant operation condition.Then,by investigating the voltage vector distribution of two generator side converters on the different fault condition,the synthetic voltage vector assignment mechanism and control strategy of the converter fault tolerant operation for open winding PMSG is proposed.Finally,the experimental system of the open winding PMSG is built to validate the availability of the proposed fault-tolerant operation strategy.
