一种基于小波基函数的电网故障测距方法研究
A Power Network Fault Location Methods Based on the Wavelet Function
摘要
Abstract
In order to improve the accuracy of fault location, a new method which adopting avoiding wave speed of the transmission line fault lo-cation was proposed based on the combination with the wavelet transform The results were verified by the actual breakdown data of Xi'an power sup-ply bureau through comparing with dBN and cubic B-spline wavelet, and combining the new method The experiment results indicated that three B-spline wavelet combinated with the new method can best satitfy the people's need,as it got a close to the atual distance in measurement,its accuracy way higher than the db3 wavelet and the new method and it got the far below error than the db3 wavelci funtion.关键词
