一种多相多绕组牵引传动系统及其控制方法
摘要：
本发明公开了一种多相多绕组牵引传动系统及其控制方法，系统包括：相数为M，每相包括N个绕组的多相多绕组电机，M≥3，N≥2；N个多相变流器模块，多相变流器模块包括M相相互并联的桥臂，每相桥臂的中点均与多相多绕组电机一相中的一个绕组相连，每相绕组均引出N个接线端子，并由N个多相变流器模块分别独立驱动；N个分控单元，每个分控单元均与一个多相变流器模块相连；主控单元，主控单元与N个分控单元相连。本发明能够解决现有牵引传动系统及其控制方法系统可靠性低，运行效率低下，运行噪声和转矩脉动大的技术问题。
摘要（英）：

The invention discloses a multi-phase multi-winding traction transmission system and a control method thereof. The system comprises a phase number M, N multi-phase converter modules, N sub-control units and a main control unit. The phase number is M, each phase comprises a multi-phase multi-winding motor with N windings, M is larger than or equal to 3, and N is larger than or equal to 2; the multi-phase converter module comprises M phases of bridge arms which are connected in parallel, the middle point of each phase of the bridge arm is connected with one winding in one phase of the multi-phase multi-winding motor, N wiring terminals are led out from each phase of winding, and N multi-phase converter modules are independently driven respectively; each sub-control unit is connected with onemultiphase converter module; and the main control unit is connected with N sub-control units. The multi-phase multi-winding traction transmission system and the control method thereof can solve the technical problems of low system reliability, low operation efficiency, high operation noise and high torque pulsation of the traction transmission system and the control method thereof in the prior art.
