摘要
利用小波变换检测突变信号的原理,可以在电力系统故障发生的瞬间快速检测出电流或电压突变信号。探讨了用小波分析原理构成微机线路保护启动元件的方法。
According to the theory of testing abrupt signals with wavelet transformation,the abrupt signals of current and voltage can be quickly detected when power system faults occur.A method,which forms start component of microprocessor based transmission line relay protection by the principle of wavelet analysis is discussed.
