A Novel Iterative Approach for Fault Location in Radial Cable Distribution Systems

This paper presents a new approach for accurate fault locating in radial cable distribution systems, which uses calculated fundamental voltages and currents extracted from measured samples at relaying point. In fault distance calculation technique, by calculating fault loop impedance using initial load flow in some iteration and by dividing fault loop impedance into the real and imaginary components, the accurate location of fault and resistance can be obtained. The proposed method has been simulated and studied for different fault conditions by using the Electromagnetic Transient Program (EMTP) for the modified IEEE 37-bus standard cable networks with symmetrical three phase cables. The results of this current study show very accurate fault location as presented in this paper.
