Automatic Positioning Method for Single-Phase Grounding Fault Points in 110 kV and Above Transmission Lines
In order to improve the accuracy of single-phase grounding fault location,an automatic location method for single-phase grounding fault points of 110 kV and above transmission lines is proposed.The fault signals of 110 kV and above transmission lines are collected,and the traveling wave signals are used to extract and analyze them.Based on the fault traveling wave signals,the fault distance is measured to locate the single-phase grounding fault point.The test results show that this method can achieve high-precision fault location and has good application effect.
