摘　　要：分析了沪西特高压站投运后,上海机组和特高压站无功补偿设备对沪西中压侧电压无功分布的影响,作出了电压无功分布平行四边形,并考虑沪西主变潮流对该平行四边形的影响。以此为基础,提出了基于改进九区图的沪西站电压无功综合控制策略,减少了设备动作次数,避免了系统运行点在相邻区域内振荡。This paper analyzes the impacts of Shanghai power unit and reactive power compensation device in UHV substation on Huxi medium-voltage side voltage and reactive power distribution after Huxi UHV Substation has been put into operation.The parallelogram about voltage and reactive power control distribution is formulated considering the influence of Huxi main transformer trend.Then the integrated voltage and reactive power control strategy is proposed for Huxi UHV Substation based on the improved nine region plot,conducive to reducing the number of device action and avoiding the oscillation of system operating points in the adjacent range.
