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。

Abstract

This article introduces the operation status of reactive voltage and existed problem of regional 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

5 kV main transformer′s reactive power

rural power grid’s reactive power and partial reactive power

conducts analysis of the reactive power balance and voltage.It finally describes the countermeasures on improving the management of grid reactivity and voltage.
