    摘 要:10 kV 線路配電網(wǎng)中大量的感性負(fù)荷需要從電網(wǎng)吸取大量的無功功率,導(dǎo)致線路的功率因數(shù)較低,末端電壓質(zhì)量較差。通過對柱上一體化電容器開發(fā)設(shè)計(jì),并針對 10 kV 線路負(fù)荷和電壓無功需求波動數(shù)據(jù)分析,制定了 10 kV 線路無功補(bǔ)償多分組自動投切的解決方案,實(shí)際應(yīng)用成效表明,該方案解決了 10 kV 線路末端電壓低、功率因數(shù)較差、補(bǔ)償設(shè)備故障率高的問題。

    Abstract: A large amount of inductive loads in the 10 kV line distribution network require a large amount of reactive power to be absorbed from the power grid, resulting in low power factor and poor terminal voltage quality of the line. Through the development and design of the on-column integrated capacitor, and the analysis of the fluctuation data of the load and voltage reactive demand of the 10 kV line, a multi-group automatic switching solution for the reactive power compensation of the 10 kV line was formulated. The practical application results show that the scheme solves the problems of low voltage at the end of the 10 kV line, poor power factor and high failure rate of compensation equipment.
    Key words: distribution network; on-column integration capacitor; multi-group compensation; voltage governance
