Abstract
This paper analyses the performance of a high reliability multiphase electric drive system. The drive system consists of a five-phase synchronous reluctance machine (SynRM) connected to a three to five-phase matrix converter (MC). In this system, there is no vulnerable electrolytic DC-link capacitors, which considered a point of failure in conventional electric drive systems. The indirect space vector modulation (SVM) is used to control the five-phase MC. Indirect SVM deals with the five-phase MC as a virtual two-stage converter consisting of a virtual DC link, a virtual rectifier stage and a virtual inverter stage. In addition, a modified closed loop field-oriented control based on the indirect SVM is proposed to control the five-phase SynRM. The performance of the drive system is analyzed at different operating conditions.
本文分析了一种高可靠性多相电驱动系统的性能。驱动系统由一个五相同步磁阻电机(SynRM)连接到一个三到五相矩阵变换器(MC)。在这个系统中，没有易损坏的电解直流链路电容器，这在传统的电力驱动系统中被认为是一个故障点。采用间接空间矢量调制(indirect space vector modulation, SVM)对五相混合电源进行控制。间接空间矢量调制将五相混合电源作为虚拟两级变换器，由虚拟直流链路、虚拟整流级和虚拟逆变级组成。此外，提出了一种基于间接支持向量机的改进闭环面向场控制方法来控制五相SynRM。分析了驱动系统在不同工况下的性能。
