摘要
开绕组电机系统是将常规电机的绕组中性点打开,两端各串接一个变换器而形成的一种双端供电的新型电机系统拓扑结构。开绕组电机系统具有输出功率高、供电模式和电压矢量调制方式多样、控制灵活、冗余性和容错性强等优异特性,在高功率、大容量、宽运行范围场合具有广阔的应用前景。通过对开绕组电机系统在国内外的研究和发展现状进行了分析和总结,介绍了开绕组电机系统的多种拓扑结构及其多电平特性,对开绕组电机系统的控制技术进行了全面综述,总结了开绕组电机系统的特性,讨论了其未来的发展趋势。
Open winding electric machine (OWEM) system is a new machine topology. It is realized by opening the neutral point of winding and connecting each side of the stator winding with a converter. OWEM system has many advantages, such as high output power, selective power supply mode, diverse voltage vector modulation methods, flexible control strategy, redundancy and fault tolerance capability. It also shows broad prospects in high power, large capacity and wide operationrange applications. In this paper, the worldwide research and development of OWEM were analyzed and summarized firstly. And then various topologies and multi-level properties of OWEM system were analyzed. Meanwhile, the modulation and control technologies of OWEM were overviewed. Finally, the characteristics of OWEM were summarized, and its future trends were also discussed.
