Phasor measurement unit based local fault detection in distribution systems

Distribution systems with advanced metering infrastructure offer many opportunities for fault detection. A novel approach is presented in this paper local diagnosis neighbour area networks by utilizing data concentrators. lightweight diagnostic function based on first engineering principles. It shown that from four phasor measurement unit data, a can be detected between buses and parameters evaluated. The of network accomplished as sequential application the method. Edge cases limitations method are explored. applicability demonstrated real world case study. By introducing threshold values parameters, results fulfill expectations.
