Research on a Distribution Line Zero Mode Current Traveling Wave Fault Location Method Immune from Wave Velocity Affection

Abstract:

This paper presented a research on zero mode current traveling wave based distribution line fault location method which is not affected by wave velocity. The mathematical expressions of initial distribution line fault current traveling wave, reflection wave of the fault location and the refraction wave of opposite ends are derived. And the directivity relationship and identification method of these three element are fully analyzed. Based on the research process mentioned above, the fault location method introduced in this paper eliminates the error produced both by velocity propagation and clock synchronization. In this way, the veracity and reliability of short distribution line fault location was improved.
