Performance Evaluation of the Harmonic Parameters for High Impedance Fault Detection in Distribution System

배전계통의 고 임피던스 고장 검출 고조파 변수 성능 평가

High impedance fault(HIF) is random in its behavior even in a similar environment. The detection of Ire HIF has focused on the development of algorithms based on harmonic, parameters of the arc currents. However, a fact that proper selection of the harmonic parameters, rather than algorithm selection, is more important is shown in this paper by applying three different performance evaluation methods on two HIF detection algorithms using eight harmonic parameters.
