In China, the method of neutral resonant grounding and neutral ungrounded are widely used in distribution networks. When grounding fault occurred in distribution net work, the fault current is small, and vulnerable to the outside interferences, so the fault features are difficult to be detected. To solve this problem, a new method of fault section location based on intrinsic mode function (IMF) energy...
In order to solve the problem that the accuracy of fault location is influenced by traveling wave speed and conductor sag, a new method of traveling wave fault location based on the distance proportion and time difference presented in this paper. Firstly, installed traveling wave acquisition device at the end of each line and substation bus in distribution network, a standard array of the arrival...
