It is an important function of direct current control and protection system to keep reactive power balance of con-vertor station and meanwhile an important way to ensure safe and stable operation of power grid.According to characteristic of reactive power requirements of DC convertor station and combining with sending and receiving ends alternative current system,this paper analyzes reactive power balance and compensation scheme for the convertor station and discusses total ca-pacity of reactive power compensation devices and cluster configuration scheme.In addition,it summarizes main problems faced for double circuits on the same tower DC reactive power control system and proposes corresponding solutions.
