Impact of stator interturn short circuit fault on shaft voltage in a synchronous generator
نویسندگان
چکیده
Abstract Shaft voltage often exists in synchronous generators due to the assembly error or various faults after long‐term performance. The article investigates shaft characteristic under stator interturn short circuit (SISC) condition. Different from other studies, this mainly considers mapping relationship between amplitude–frequency characteristics of and SISC degrees. detailed expressions are first derived based on magnetic flux density normal condition Then finite element analysis experiment is studied a CS‐5 prototype generator with two poles order validate theoretical formula. result shows that there no condition, while generated obviously Meanwhile, frequency component composed odd harmonics including first, third fifth harmonics.

A Comprehensive Mathematical Model for Analysis of WR-Resolvers under Stator Short Circuit Fault
Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

In this paper, a novel method is presented for detection and classification of the faultyphase/region in the stator winding of synchronous generators on the basis of the resulting harmoniccomponents that appear in the terminal voltage waveforms. Analytical results obtained through DecisionTree (DT) show that the internal faults are not only detectable but also they can be classified andthe rela...
