摘要
Detection of Faulty transient is a important problem in transient protection. In order to detect out the faults timely and reliably, a set of effective method for fault detection would be necessary. This paper built a model of 500kV HV transmission line and simulated the fault detection of single-phase-to-ground uder various conditions. Based on the definition of WEE, WTE, WSE, WTFE, WAE and WDE, the paper put them into application of faulty transient detection for the first time and analyzed the detecting ability of each wavelet entropy. Finally, the simulations which compared wavelet entropy with wavelet modulo maximum prove that the fault detection based on wavelet entropy is superior to other methods.
