Stator Current Harmonic Assessment of Induction Motor for Fault Diagnosis

This paper presents an assessment of motor current signature analysis for fault diagnosis of an induction motor. Single phasing fault has been considered and stator current harmonics are analyzed by assessing peaks and symmetry in harmonic spectrums both at normal condition and at fault condition. ‘db4’ is used for current signature analysis wavelet decomposition. A comparative observation is m...

15 Years of Exerience with 100% Generator

This paper discusses the application of three different 100% stator ground fault protection schemes. Two third-harmonic methods and a low frequency-injection method are discussed. Third-harmonic schemes have been widely applied on generators within the U.S. to provide stator ground fault protection over the entire stator winding. In many cases, however, these schemes have been found not to be a...

Double Stator Induction Generator Model for Autonomous Operating Mode

Due to speed fluctuations of unregulated wind turbines, the terminal voltage may increase to dangerously high levels which have been reported to cause capacitor failure at wind farms. In this topic this paper examines a steady state performance analysis of stand-alone double stator induction generator self excited with two independents capacitors banks. An impedance approach based on double thr...

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...

Stator Turn-to-turn Fault Detection of Synchronous Generator Using Total Harmonic Distortion (thd) Analyzing of Magnetic Flux Linkage

Diagnostics of synchronous generator turn-to-turn faults can be accomplished by analyzing the anomalies of machine local variable such as magnetic flux linkage. On the other hand, because current transformers and voltage transformers are usually installed in the machine for different purposes as default, the monitoring schemes that depend on the study of these inputs have become a topic of inte...
