Abstract

The two converters are the basic parts of a unified power flow controller (UPFC). Based on the widely used MATLAB, a digital simulator for the UPFC with 12-pulse converters is developed. Simulation results show that the developed UPFC model is precise in reflecting the static and dynamic characteristics of the UPFC. The harmonics of the output of the model is also analyzed. Using a simple power system with the UPFC as an example, the dynamic characteristics of the UPFC is studied based on the model which has been developed. The simulation results show that the normal operating condition of UPFC could no longer be maintained following a severe disturbance. Furthermore, the fault status of the system could be aggravated by the UPFC if it is used only for power flow control
