Abstract

Because of the H₂/H_infin control has good robustness and performance, the H₂/H_infin control strategy of SVC is designed for improving the voltage characteristics, damping system oscillation. In the three-phrase short simulation, the transient responses of the main parameters of the H₂/H_infin controller and the conventional controller are compared and analyzed. The result demonstrates that the H₂/H_infin, control makes the overshoot adjustment smaller and down time shorter and enhances the voltage characteristics. The H₂/H_infin SVC controller can damp systems oscillation quickly, improve the dynamic performance stability of power system and voltage characteristics at the location of SVC greatly and has good dynamic quality and robustness.
