Real Fault Location in a Distribution Network Using Smart Feeder Meter Data

Distribution networks transmit electrical energy from an upstream network to customers. Undesirable circumstances such as faults in the distribution can cause hazardous conditions, equipment failure, and power outages. Therefore, avoid financial loss, maintain customer satisfaction, reliability, it is vital restore fast possible. In this paper, a new fault location (FL) algorithm that uses recorded data of smart meters (SMs) feeder (SFMs) locate actual point fault, introduced. The method does not require high-resolution measurements, which among main advantages method. An impedance-based technique utilized detect all possible FL candidates network. After occurrence, protection relay sends signal SFMs, collect active connected lines after fault. higher value represents real faulty section due high-fault current. effectiveness proposed was investigated on IEEE 11-node test MATLAB SIMULINK 2020b, under several situations, different resistances, distances, inception angles, types. some cases, found two or three for FL. these estimation helped identify candidates. Section performs well simulated cases. results showed accurate able precisely section. To experimentally evaluate method’s powerfulness, laboratory its simulation were carried out. distinguish experiment. revealed robustness
