Summary:
This paper presents a diagnostic technique for power quality analysis against different disturbances in electrical power sources. The presented technique utilizes a wavelet packet transform (WPT)-based a proposed algorithm for monitoring and detecting various disturbances occurring in supply voltage signal and in supply frequency. The values and the time locations for low and high-frequency coefficients are determined up to level six and compared with a threshold determined from the operation of a healthy source. The proposed technique is tested on certain cases and the simulated results indicate that this technique is effective for detecting and monitoring different mentioned disturbances.
