According to the different compensatory objects, this paper took a project which based on symmetry components to compensate. When SVC is used as the system compensatory, it is mainly used to adjust the system voltage. Therefore, the balanced control strategy is adopted. When SVC is used as the load compensatory, it is mainly used to restrain the voltage fluctuation and flash during the running of the impactive loads,so the unbalanced control strategy is adopted. According to this project, the hardware and software for the control system of SVC are designed.

本文首先分析了无功补偿的基本原理，针对SVC补偿对象的不同，采用一种基于对称分量法的SVC分相补偿方案：作为系统补偿时，SVC主要用来调节系统电压，因此采用平衡控制策略；而作为负荷补偿时，SVC主要用来抑止冲击性负荷运行时引起的电压剧烈波动和闪变，因此采用不平衡控制策略，依据此方案，对SVC控制系统的软、硬件进行设计，对控制系统的数据处理方法及控制策略也进行了详细的分析。
