Abstract

This paper presents the power system application of a PWM base UPFC through EMTP simulation. A PWM base UPFC model is constructed and detailed switching-level simulation is performed using EMTP. The dynamic responses of UPFC are analyzed. Based on the simulation results, the appropriate equivalent impedances of UPFC voltage-source model which represent similar dynamics with PWM based UPFC are determined by optimization routine. This paper also analyzes the influence of the power system strength on the dynamic responses of UPFC. Finally this paper shows that the performance of UPFC is improved by control parameter tuning when UPFC is installed to weak power system.
