To precisely locate the grounded fault area in distribution network with DG, a new grounded fault area location algorithm based on three-phase impedance model and fault features in distribution network with DG is proposed in this paper. This method establishes three-phase impedance model if the distribution network with DG, analyzes and extracts the fault characteristics on the basis of the thr...

An irregular activity on electric power distribution feeder, which does not draw adequate fault current to be detected by general protective devices, is called as High impedance fault (HIF). This paper presents the algorithm for HIF detection based on the amplitude of third and fifth harmonics of current, voltage and power. This paper proposes an intelligent algorithm using the Takagi SugenoKan...

Predominantly the impedance faults can be classified as Low Impedance Faults (LIF) and High (HIF). The LIF detected protected by a conventional protective device. However, if fault occurs in system, it is difficult to detect because of low magnitude current. overcurrent relay, which smartly detects faults, fails faults. This research work organized two components. In first component some litera...

Detection of the high impedance fault (HIF) in distribution systems is significant for power utilization safety. In addition to low currents, traditional approaches are invalid detect HIFs also due diverse characteristics, including slight HIF nonlinearity during weak arcing process, distortion offset caused by lag heat dissipation, and interference background noise. This paper proposes a disto...

Determining the fault location using conventional impedance based distance relay in the presence of FACTS controllers is a challenging task in a transmission line. A new distance protection method is developed to locate the fault in a transmission line compensated with STATCOM with simple calculations. The proposed protection method considers the STATCOM injected/absorbed current to correct the...

High-impedance faults are a challenging problem in power distribution systems. They often do not trigger protection devices and can result serious hazards such as igniting fires when contact with vegetation. The current research field dedicated to studying these is extensive but suffers from constraining bottleneck of lack real experimental data. Many works set detect localize rely on high-impe...
