Laboratory Demonstration of UPQC System

The Unified Power Quality Conditioner (UPQC) is a developed Custom Power Device designed to improve power quality in distribution networks. By addressing both voltage and current-related power quality disturbances, the UPQC plays a vital role in maintaining optimal power conditions. This paper focuses on the implementation and laboratory testing of UPQC control strategies using the Imperix Rapid Control Prototyping system. Distinctive consideration is given to the UPQC's performance in environments with unbalanced and distorted grid conditions, as well as in the existence of non-linear harmonic loads. The proposed control strategy is useful and improves the UPQC's performance in dynamic and steady-state conditions. Laboratory experiments confirm the effectiveness of the control schemes, indicating significant improvements in power quality. Models developed in MATLAB/SIMULINK support the validation of the anticipated control strategy, highlighting its efficacy in practical-world applications.
