摘要
介绍了地区电网无功电压运行情况及存在的问题,并从电压合格率指标、无功两方面进行分析。指出500 kV、220 kV、110～35 kV主变无功、农网无功和局部无功等5个当前地区电网无功运行现状特征,进行无功平衡及电压情况分析。最后详尽阐述了提高电网无功、电压综合管理水平的对策和措施。
This article introduces the operation status of reactive voltage and existed problem of re- gional power grid, and analyzes in two aspects： the rate of qualified voltage and reactive power. It points out 5 features of reactive operation at present regional power grid such as 500 kV, 220 kV and 110 ~ 35 kV main transformer＇s reactive power, rural power grid＇ s reactive power and partial reac- tive power, conducts analysis of the reactive power balance and voltage. It finally describes the countermeasures on improving the management of grid reactivity and voltage.
