基于小波变换的输电线路行波测距研究
A study of fault distance measurement with travelling wave for transmission lines based on wavelets transform
【摘要】 结合小波变换的奇异性检测理论和行波理论 ,介绍了输电线路单端测距的方法。与传统测距方法相比 ,这种测距方法具有硬件投入少、不受双端同步时钟的影响、测距误差小等优点。
【Abstract】 This paper introduces a method of one-end fault distance measurcment in transmission line, according to the theory of singularity detection in wavelet transform and the theory of travelling wave. Compared with traditional method, the method excellents in using less hardware, free of influences in both-end-synchronous clock, and low deviation in fault location.
