Wavelet-Based Algorithm for Fault Detection and Discrimination in UPFC-Compensated Multiterminal Transmission Network
2021
As interconnected power system transmission line systems are more complex in evaluating system performance, and adding FACTS devices in the power system requires more attention in the analysis. Nowadays FACTS devices play a major role in improving the performance of transmission lines. The evaluation of dynamic behavior during transient conditions is becoming a great difficulty, particularly, for larger networks. Wavelet analysis will give the entire system performance at any part of the system. This paper mainly concentrates on fault detection and its classification of multiterminal networks. It also gives a critical evaluation of nine zones of performance under different fault conditions. Wavelet-based analysis in the presence of UPFC (unified power flow controller) by using Bior 1.5 has been performed. The performance of multiterminal transmission networks with and without controllers under different fault conditions has been estimated.
