随着电力系统的不断扩大，电力系统的自动化水平越来越显得重要，再者，电力系统诸多领域通常将大规模电网进行分区分析、监视和控制等，这样不仅缩短了计算时间，提高了效率，而且合理的分区可以充分发挥控制作用，降低成本，提高经济效益。实现无功电压的自动化控制，目的是使无功平衡及电压稳定具有针对性和实用性，这样电网电压质量得到提高，调度员和监控员工作效率也大大提高了。无功电压自动调节主要通过SCADA系统实现。In this paper, we will discuss about the AVC system. With the power system expanding day by day, the level of automation in power system is more important,furthermore, usually analysising , monitoring or controlling by districting in many areas of the power system, this method not only shorten the time or increase efficiency, and play controlling effect fully if the partition is rational, reduce the cost, increase economic benefits. To achieve the automatic voltage control for reactive balance and voltage stable with practical or targeted, the level of the voltage is increased, the efficiency of the dispatcher or the controller will improved greatly. the automatic voltage control of regulation is realized by SCADA.
