Earth Fault Location in Medium Voltage Power System Network

Abstract

Electric in power systems network is always exposed to failures that can be caused by natural phenomena or human errors. This paper focused on the fault localization method on medium voltage (MV) power system network. Faults that occurred in a power system network may damage the system which res ult s in the components of the system failure. A network of MV power system network was constructed using ATP/EMTP software to simulate and analyse an earth fault transient signal for earth fault location purpose The transient signal produced from the simulation of ATP/EMTP software w as analysed using MATLAB software. All the data and the signal of the dominant transient frequency were collected and train ed in Artificial Neural Network (ANN) ANN). The ANN model is us ed to locate an earth fault location in the simulated power system network. Based on the result , the system works as being expected.
