摘 要:變電站無功需求受負荷波動變化影響較大,而主變配置并聯電容器裝置分組較少,單組容量大,存在不投欠補過大、投入過補過大的問題,不能實現無功就地平衡與降低損耗。對變電站改造前情況進行了分析,通過對 35、110 kV 變電站負荷和無功需求波動數據分析,制定出并聯電容器裝置以多分組自動投切的解決方案, 解決了無功補償不充分、功率因數較低的問題。

Abstract: The reactive power demand of a transformer substation is greatly affected by load fluctuation changes, while the shunt capacitor device configured with the main transformer has fewer groups and each group has larger capacity, so whether the input of reactive power compensation or not cannot achieve reactive power on-site balance and reduce loss. After analyzing the substation before transformation, the paper, based on the analysis of load and reactive power demand fluctuation data of the 35、110 kV substation, develops a solution of multigroup auto-switching of the shunt capacitor device, settling matters of inadequate reactive power compensation and lower power factor.
Key words: capacitor; multi-group; automatic control
