High Impedance Fault Location in Transmission Line Using Nonlinear Frequency Analysis

摘要：

The detection and location of high impedance faults on power system has been one of the most difficult problems in power transmission and distribution systems. According to a very highly nonlinear behavior of high impedance faults, a methodology is presented to locate high impedance faults in power system. The proposed technique is based on the fact that high impedance faults in power line can make the whole system behave nonlinearly. Consequently, the location of high impedance fault can be determined by detecting the position of nonlinear component in power line systems. The effectiveness of the method has been verified through simulation studies.
