Abstract

According to multi-branch structure of high voltage power network in coal mine, a new method based on singular value decomposition (SVD) was proposed. The characteristics of reflection and refraction of the traveling wave generated by the fault point were studied and the values measured by devices at initial side of each section were decomposed by SVD after Phase-model transformation. Traveling waves will produce mutations, fault section is the one whose first mutation of forward traveling wave is maximum. This method is simple and effective, and it is not affected by grounding resistance and inception angle. This method can be applied to single-phase and multi-phase grounding and phase-phase short.
