摘要

提出了一种在闭环条件下监测非正弦电动势永磁同步电动机匝短路故障的方法。该方法将扩展Park框架下的多模型方法与递推最小二乘算法(RLS)相结合。用扩展Park模型与PMSM之间的结构面距离来表示断层及其严重程度。

Monitoring of turn short-circuit faults in stator of PMSM in closed loop by on-line parameter estimation

This paper presents a method for monitoring of turn short-circuits faults of permanent magnet synchronous motor (PMSM) with non sinusoidal electromotive force (emf) in closed loop conditions. The proposed method is formulated by combining multi-model approach in Extended Park frame and the recursive least squares algorithm (RLS). The fault and its severity are indicated by the surface of structure distance between the Extended Park model and PMSM.
