Design and simulation of UPFC for enhancement of power quality in transmission lines

Abstract

Growth of electrical energy consumptions and increasing non-linear loads in power systems force the electrical power utilities to provide a high quality electrical power. This is the reason that this issue is getting more and more importance in power systems. This paper examines all power quality paramete-rs based on the standard. In order to enhance the power quality, these parameters must be improved; to do so a compound compensator UPFC is designed and its performance is simulated for electrical power transmission lines. To verify the results of application of the above-mentioned method, they are compared with the corresponding results obtained by PSCAD/EMTDC software.
