Abstract :
A pair of back-to-back power electronic inverters can control the real and reactive power flow in a transmission line. This configuration is called a unified power flow controller (UPFC). This paper presents a control strategy based on d-q axis theory for the operation of a UPFC. A new decoupling control strategy for the series converter and coordination control for the shunt converter is tested with a laboratory prototype UPFC. Experimental results indicate the effectiveness of the proposed control scheme
