AN ANFIS BASED FAULT LOCATION IN POWER DISTRIBUTION NETWORKS.

One of the most important functions of distribution automation is automated fault location. The knowledge-based techniques are becoming more successful in enhancing the accuracy of fault location in power distribution networks. Adaptive network-based fuzzy inference system (ANFIS) with hybrid learning algorithm was employed in this article to arrive at an accurate fault location. Three main estimations were done by the ANFIS fault models designed and developed in MATLAB® - fault type classification, faulted line-segment detection, and fault location on that faulted line segment. This estimated information is vital for distribution substation engineer, and greatly facilitates the substation maintenance crew in reaching the faulty spot quickly for repair and power restoration. The results obtained demonstrate higher levels of accuracy and efficiency, and thereby can greatly enhance the power system reliability and quality. [ABSTRACT FROM AUTHOR]
