Power Quality Issues and Mitigation Strategies: A Review

Abstract

Abstract

To protect the power system recognition and arrangement of voltage (V) and current (I) issues are essential tasks. Most power quality (PQ) disturbances are unstable and ephemeral; the call for recognition and arrangement of voltages and current is proved. There are some intelligent system technologies which have dominance regarding fault analysis by using wavelet transform (WT), expert systems and artificial neural networks. As signals are classified in six classes: five types of disturbances: including sag, swell, transient, fluctuation, interruption, and the normal waveform. The motive of this paper is to examine the frequent power quality issues, the outcomes of the harmonics on the power quality, the methods to figure out the quantity of harmonic distortion existing in power system which keep out the reasons of the trouble and in the end device a solution for up to the mark of power quality.
