摘要
Abstract
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.关键词
