摘　　要：在传统AVC分级分区控制策略的基础上,加设了负荷预测环节和考虑设备当前状态电气控制属性诊断环节,使控制策略更加具有预见性,并根据设备的运行状态实现超前控制,减小了设备动作延时。系统已投入安徽芜湖地区电网实际运行,实验结果表明系统对提高地区智能电网电压合格率、优化无功有较好的效果。新系统优化了设备动作次数,显著减小了因设备频繁动作导致的设备损坏事故,提高了设备使用寿命。To the hierarchical zonal control strategy of the conventional AVC system,we add a load predication process and a diagnosis process for current electrical control status to enhance the predictability of the control strategy. Furthermore,based on the operational status of the equipment,advanced control is realized,thus reducing the equipment action delay. This system has been put into operation in the power grid in Wuhu area of Anhui province. Experimental results show that the system produces a good effect in increasing the voltage qualified rate of the regional smart grid and optimizing reactive power. The new system optimizes equipment action times,substantially reduces equipment damage accidents caused by frequent actions and extends equipment life span.
