Abstract :
In this paper, a control strategy for a three-phase UPFC-based voltage compensator with the function of current and voltage balancing is proposed. Line voltage variations and line current and voltage unbalance are compensated simultaneously by the proposed compensator. A method for detection of negative-sequence components of three-phase line currents is shown which is needed in performing unbalance compensation. Simulation analysis is carried out to show the dynamic performance and effectiveness of the compensator. Experimental results are included to show the validity of simulation analysis
