    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
