A Rigorous Overview of Unified Power Quality Conditioner for Alleviation of Power Quality Issues

Dinesh Mahendra Matlani | Mehul Dansinh Solanki

Abstract: In this paper, an absolute overview of the Unified Power Quality Conditioner (UPQC) is given. UPQC is a kind of custom power devices, employed in the distribution network to improve power quality. In the distribution system, due to the use of various non-linear loads (power electronic devices, computers, arc furnaces, LED lights, refrigerators, SMPS, etc. ), various power quality issues take place. In this work, different power quality issues have been discussed with their impact on the equipment, its suggestive mitigating devices have been explained to address these power quality issues. The focal point of this work is to give a broad review of UPQC. Classification of UPQC is given in various categories viz. physical structure, configuration, function, task, and applications. Ample elaboration on the explanation of each type of UPQC has been provided along with its appropriate control strategies.
