摘　　要：本文针对静止型无功补偿器(SVC)系统的非线性特点,设计了电压导纳双闭环控制系统,采用模糊-PI控制方法,该方法结合了模糊控制可实现动态过程快速调节和PI控制可实现稳态过程精确调节的优点,使SVC系统获得良好的控制性能。通过TCR投入系统中的无扰动实验和模拟无功负载扰动的冲击性负荷响应实验,验证了本文设计的SVC系统具有无扰动投入、响应速度快、过渡过程短、精度高等特点,实现了预期的设计目标。In this paper, the design of voltage admittance double closed loop control system is aimed at the nonlinear characteristics of the static var compensator（SVC） system. Used the fuzzy-PI control method, which combines the advantages of fuzzy control PI method can realize fast dynamic process regulation and PI control method can realize precise steady process adjustment, can have the SVC system achieve a good control performance. Through the no disturbance experiment of TCR input in the system and the impact load response experiment of simulate reactive power load disturbance, verified that the SVC system designed in this paper has no disturbance input, fast response, short transition process, high precision, and achieve the desired design goals.
