摘    要：论述了ASVG的工作机理和在系统电压对称时的动态数学模型,并针对系统电压不对称时ASVG的运行与控制问题,分析了系统电压不对称时的被控对象模型,提出了恒电压不对称专家PID控制方法,给出了系统有15%的负序电压时的仿真结果.结果表明:该控制方法可以有效地减少系统电压不对称对装置的影响,且装置起动过程超调和输出电压波动小,控制灵活,具有鲁棒性.

Abstract: The mechanism and dynamic model of ASVG is introduced in this article at first. Then the authors point to the problems of running and control of ASVG under asymmetric conditions of power system, and put forward the asymmetric expert PID control law. Under the experimental condition of 10% negative voltage, the simulated results are given. The parameters of controller can self-adjust on line, and the influence of asymmetric voltage can be greatly reduced. Using this control law, the control of ASVG is flexible and the response is quick.
