摘要
根据测距式行波保护的基本原理及各种关键问题的对策 ,给出了实现测距式行波距离保护完整的原理方案。基于 B样条小波的二进小波变换被用来实现行波信号的奇异性检测和消噪。针对测距式行波保护原理本身及各种对策 ,进行了大量详尽的 EMTP仿真。仿真结果证明了测距式行波保护原理。
Based on the theory of travelling wave- based distance protection with fault location TVDPFL and countermeasures of key technical problem s,the implemental principle scheme of TVDPFL is presented. Dyadic wavelet transform based on B- spline waveletfunction is adopted to diminish the noise signal and im plem ent the singularity detection of travelling waves. L arge amounts of EMTP sim ulation prove the correction of the theory and the countermeasures of TVDPFL.
