Research on Bus Travelling Wave Protection Based on Wavelet Transform

CUI Lu,CHAO Qin,CUI Li-fu(School of Electrical Engineering,Xinjiang University,Wulumuqi 830008,China)  
Wavelet transform has succeeded in the part fields of electric power system.Transient travelling wave protection is an important branch of relay protection.The wavelet transform is used in analysis of initial current travelling wave signal,forming the bus protection principle.Finally,use transient analysis software ATP of electric system to verify the simulatim and propose hardware scheme.
