State of Arts of Fault Detection Arithmetic of Power Systems Microcomputer Protection
摘要
Abstract
The transient current signal includes a period component varying in Spectral waveform, a non -period component varying in exponential waveform and switching operation sequence when the power system goes wrong. To work out veracious electric parameter, the current methods for the fault information analysis of microcomputer protection of power systems including FFT, Least squares, neural network, wavelet transform are surveyed. Finally, several key technical issues and the main development trends of the topic are pointed out to solve the practical problems and motivate further development.关键词
