摘　　要：阐述了区域AVC系统的三级电压控制理论,介绍了AVC系统的控制原则及系统组成,分析了AVC系统在石嘴山电网的应用效果。基于电网无功调控能力和关口无功功率控制范围,实现自动电压控制方法,提出了区域电网无功电压优化目标方案及分布式控制策略。在石嘴山地区电网验证了自动电压控制的有效性,AVC系统的分级电压控制方案,既降低了系统网损,又保证了系统电压质量,是一种行之有效的工程实施方案。This paper expounds the regional automatic voltage control（ AVC） system based on threelevel hierarchical of voltage control theory firstly,and then introduces the control principle and system composition of AVC system,and finally analyzes the application effect of AVC system in Shizuishan power network.Based on the reactive power control of the power grid and the checkpoint,the method of automatic voltage control is presented,and the scheme of reactive power and voltage optimization and distributed control strategy are proposed. The effectiveness of automatic voltage control is verified in Shizuishan regional power grid. The voltage control scheme of AVC system,which can not only reduce the system loss and guarantee the system voltage quality,is a kind of effective project implementation plan.
