Power System Fault Analysis Using Signal Processing Technique – A Review

Abstract: The power quality is a very important issue in electrical power system. Electrical transmission lines are one of the vital components of this power system which play important role in power quality during electricity transmission. These transmission lines are exposed to faults most of time due to atmospheric conditions as well as due to overload. Various methods are established for fault analysis occurs on transmission lines. The study of these methods is necessary for performance improvement as well as to maintain the reliability and stability of the power system in any critical event. This paper presents a review on the signal processing tools used to analyze the behavior of a power system and evaluate the performance of the system for different scenarios
