Abstract
The purpose of this research is to evaluate the function of a Unified Power Quality Conditioner (UPQC) in a system of distribution that includes three wires and three different stages. The UPQC is a noteworthy example of a tailored power solution that is capable of efficiently addressing load balancing, the adjustment of power factors, and the suppression of current and voltage harmonics. The system is able to handle a broad variety of load configurations, including linear, inconsistent, and oscillating loads in any combination. Acquiring the reference signals for each and every one of the active electrical power filters in the series and the active power filters in the shunt requires the use of the unit template technique, abbreviated as UTT. The filters that have been constructed make use of a pair of proportional-integral (PI) controllers that are closed-loop. The arrangement of a shunt controller (SHUC) and a series controller (SERC) is part of the layout of a three-phase three-wire UPQC (UPQC). This study examined the progression of control systems and procedures for UPQC in order to boost power quality and design a flexible control strategy for improved UPQC performance. This research focuses on enhancing the efficiency and cost-effectiveness of UPQC. The control system that has been developed demonstrates improved steady-state and dynamic responsiveness, as seen by the simulation results conducted using MATLAB/Simulink. These results provide empirical support for the effectiveness of the UPQC.
