Abstract
In the Southern African Development Community (SADC), transmission lines facilitate power utilities in distributing a considerable amount of electricity from generation stations to end users. Long conductors used in transmission lines can cover great distances. However, they are susceptible to various environmental and weather conditions which can have adverse effects such as power outages, and equipment malfunctions, posing a serious threat to the reliability of the system. Hence constant monitoring of the performance characteristics of this system is crucial. The main objective of this work is to propose an Artificial Intelligent (AI) based technique, which is the Artificial Neural Network (ANN) to detect and classify faults on a transmission line. In contrast to the most common approach viz. the protective relay system, a five-layer feed-forward-back propagation neural network architecture is proposed in this work to detect and classify faults on a 230kV transmission line system. A set of 12 fault conditions have been predefined viz. No fault, AB, AC, BC, ABC, AG, BG, CG, ABG, ACG, BCG and ABCG conditions. The results indicate that the proposed ANN approach with Levenberg-Marquardt (LM) algorithm, 5-Layers and TANSIG transfer function yield an output of 0.8927, 0.8882, 0.905 and 0.8938 in the training, validation, testing and overall accuracy respectively. To corroborate these results, a comparative study of the proposed network and other neural networks was also carried out.
