混合输电线路行波故障测距算法的设计
Design of Traveling Wave Based Fault Location Algorithm for Hybrid Transmission Lines
摘要
Abstract
This paper analyses the differences and similarities of propagation characteristics of two kinds module signals through MATLAB calculation and EMTP simulation,and proposes a novel two-terminal asynchronous fault location algo⁃rithm for cables and overhead lines based on the difference of propagation characteristics of two module signals. The algo⁃rithm can effectively distinguish the fault section and fault type,and it does not need synchronous sampling of two termi⁃nals. Besides,the algorithm is independent of the wave velocity. Compared with traditional fault location algorithm,the proposed algorithm significantly enhances the localization accuracy and lowers the cost of fault locating device. ATP-EM⁃TP simulation results show that the proposed fault location algorithm is not only feasible but also highly accurate .关键词
