摘　　要：为提高电力系统电压稳定性,综合了模糊控制和PID控制的优点,提出一种基于模糊-PI控制的SVC的电压控制器设计方法。分析了SVC电压控制器的基本原理和组成,详细介绍了模糊-PI控制的设计实现过程。用DSP作为主控芯片开发出了控制器,给出了软硬件设计思想。对SVC进行了仿真验证,仿真结果表明模糊-PI控制比传统PI控制具有更好的动态性能,较小的超调量和较短的调节时间。To improve the voltage stability of the power system, the virtues of both fuzzy control and PID control are integrated. A SVC voltage controller design method based on fuzzy-PI control is raised. Then the basic principles and composition of the SVC voltage controller are analyzed, and the design of fuzzy-PI control implementation process is described in detail. Using DSP to develop a controller, the design idea of the software and hardware is given. In order to confirm the effect of SVC, a simulation experiment is presented. The simulation results show that the fuzzy-PI control has better dynamic performance, smaller overshoot and shorter modulating time than the traditional PI control.
