【Abstract】 In this paper, a new control method of SVC (SC+ TCR) is proposed with high precision of compensation and fast re sponse time. Through the combination of PI control with the feed back of electric supply voltage and the fuzzy control with dynamic proportion factor, the control performance is improved greatly ac cording to the detected reactive power. Also, the surge current of switching on/off capacitor is avoided. The control method is ver ified by simulation.更多还原
