Abstract

The ultimate goal of the electrical industry is to supply reliable energy. Therefore, accurate and on time detection of faults have always been the main concern of electricical utility users. In recent years, the use of cables has grown steadily and has made it difficult to detect faults and locations. If the cable network is intended for a particular application, such as a generator connection cable to industrial power grid, its importance will be increased, and the Lack of timely performance of the protection system will cause irreparable damage. In this paper, a novel method is proposed for detecting and determining the location of faults in cable using a combined wavelet transform algorithm and an optimized MLP network with a bee algorithm. In the proposed algorithm, two initialization modules and prediction analyzes are proposed to increase the selection capability. The algorithm is done by the DigSILENT and MATLAB software and implemented on the ship industrial cable network. The simulation results indicate an accuracy of 93% for the considered algorithm in determining the correct location of the fault.
