Abstract :
In this paper a novel structure of a generalized unified power quality conditioner (GUPQC) which is a combination of one shunt and two series voltage source converters (VSCs) connected among three independent distribution feeders is presented. It compensates current imperfections in one feeder and voltage imperfections in the other two feeders. The proposed design of GUPQC enhances the power quality of a multi-bus/multi-feeder distribution system by minimizing voltage and current harmonics generated by distorted supply voltage and nonlinear loads. Simulation by using MATLAB/SIMULINK shows the capability of the proposed GUPQC to minimize the major power quality problems of the distribution system model.
