摘要

本文的主要目的是研究和分析基于自耦变压器的异步电动机定子绕组匝间故障。利用该方法可以很清楚地解释在不同故障严重程度和运行条件下的SWITF过程中定子电流和故障环电流的变化规律。在此基础上，提出了一种新的故障检测指标。为了验证这一理论方法，利用dq模型建立了一个带开关的感应电机模型。仿真结果表明，基于自耦变压器方法的分析是有效的。

Investigation on stator winding interturn fault in induction motor using the autotransformer based approach

The main objective of this paper is to study and analyze the Stator Winding Inter-Turn Fault (SWITF) of an induction motor based on autotransformer approach. The behavior of stator current and fault loop current can be clearly explained during SWITF at different fault severities and operating conditions by using this method. In addition, an novel indicator is proposed for SWITF for early fault detection. In order to validate this theoretical approach, an induction motor model with SWITF using dq model is developed. Simulation results show the effectiveness of the analysis based on autotransformer approach.
