Abstract

This paper presents a hybrid power quality solution in a test system consisting of distributed passive filters, an Universal Power Quality Conditioner (UPQC) and Distributed Generation (DG) units. In the system, single passive filters are designed and connected to eliminate main harmonics and compensate reactive power for each nonlinear load. The UPQC is utilized for voltage unbalance compensation and cancellation of the remaining current harmonics at the point of common coupling of the power distribution system. Configuration of the test system, nonlinear loads, DGs, active filters and UPQC and their modeling in Matlab software are presented in this paper. Matlab implementation of the control system based on dq reference frame theory is also described. Frequency response of the given system is performed and presented to study the issue of resonance under harmonic conditions. Simulation results are demonstrated and confirmed the effectiveness of the proposed configuration in simulated test system. It is shown that the UPQC rating can be reduced in the proposed configuration due to the reactive power compensation using passive filters. [ABSTRACT FROM AUTHOR]
