摘要：

A scheme of single-line-to-ground fault location in neutral non-effectively grounded distribution systems is proposed in this article. The characteristics of phase current traveling waves and line-to-line voltage traveling waves are analyzed. The wavelet transform technique is used to extract the information of the arrival times, polarities, and amplitudes of the recorded traveling waves. The fault location scheme can simultaneously realize faulty feeder identification, fault section location, and fault position location even if only two-phase current transformers are installed in the Phases A and C and feeder terminal units only to provide line-to-line voltage information. The effectiveness and practicability of the proposed scheme have been verified by PSCAD/EMTDC simulation results.
