This paper presents a comprehensive review for short circuit fault in electrical motors particularly PMSM. First different factors leading to this fault, such as various stresses on the motors, are proposed; then different fault diagnosis methods in induction motors, permanent magnet motors and brush-less dc motors are proposed. Advantages and drawbacks of these fault diagnosis techniques related...
Paralleling power converters is a common practice in industries to enhance total power rating, reliability, and availability of the system. In case of fault occurring in systems with parallel converters, the faulty power converter can be isolated and the system can still be operated at reduced power level. In this paper, a grid-connected power converter consisting of two parallel H-bridge converter,...
The integration of renewables in the distribution grid has come to play an important role during the last decade. One of the ways to do it efficient is through grid reconfiguration for power loss reduction since reconfigurable networks with low resistive losses accept more intermittent renewable generation than static ones. Thus, in this paper two reconfiguration methods for a distribution network...
This paper presents a multi-domain co-simulation based approach to identify faults in large power industrial three-phase synchronous motor drives. The goal is to develop an integrated simulation platform capable to capture faults caused by failing electronic components of the brushless exciter, as one of the key parts of these drives. The signal signature analysis is used for monitoring the operation...
This paper investigates the performance of a wound rotor induction motor (WRIM) under rotor inter-turn short circuit fault using magnetic equivalent circuit (MEC) and finite elements method (FEM). Impacts of the fault on the signals of the motor including rotor current, stator current, and developed torque of the motor are addressed. Current of short circuit turns signal is considered here. This MEC-based...
