摘要：
Integrating the self-healing capability realizes the automated protection of smart distribution systems. This article presents a fault location scheme for low voltage (LV) distribution systems based on the information collected from the smart meters. First, a fault condition is detected and classified by processing the current signal at the secondary side of the distribution transformer by an intelligent electronic device. Then, the faulty feeder and section are determined by calculating the fault-imposed component of nodal voltages. The reliable performance of the proposed scheme is verified through several case studies using a real semi-rural distribution system. This article presents a fault location scheme for low voltage smart distribution systems based on the collected data from smart meters. The proposed fault location technique is based on the fault-imposed component of nodal voltages.image
