Short-circuit Fault Diagnosis of Power System Based on Electronic Transducer
Yuanbing Zheng · Gaoya dianqi · 2011
Electrical transducer can be used to measure the real-time parameters of power system accurately due to its characteristics of wide bandwidth,large dynamic range,and unsaturation in measuring high current.This paper proposes a short-circuit fault diagnosis system based on electronic transducer.This system can extract the signals' details via wavelet transform for faults classification and pattern recognition with ANN,and can identify short-circuit fault in power system by means of expert system.On the platform of MATLAB and Visual C++,the system is simulated,and the results verify its effectiveness.
