| Abstract: | The wavelet transform analysis method is introduced. It is applied to the measurement of dead angle of differential protection of transformer and the detection of peak-wave of auto-reclosing of transmission line. The simulation result shows that this method has the ability of simple algorithm, high measuring accurance and anti-interference. Furthermore the prospect of wavelet analysis in power system, especially in relay protection is estimated. |
