云广依800 kV特高压直流输电工程采用同极双12脉动阀组串联结构，双阀组电压的平衡控制相当重要。分析了双阀组电压平衡控制的策略和实现过程，针对两起分接开关导致的电压控制异常进行了分析，并结合现场实际提出改进建议，对改善系统运行有一定帮助。
雲廣依800 kV特高壓直流輸電工程採用同極雙12脈動閥組串聯結構，雙閥組電壓的平衡控製相噹重要。分析瞭雙閥組電壓平衡控製的策略和實現過程，針對兩起分接開關導緻的電壓控製異常進行瞭分析，併結閤現場實際提齣改進建議，對改善繫統運行有一定幫助。
운엄의800 kV특고압직류수전공정채용동겁쌍12맥동벌조천련결구，쌍벌조전압적평형공제상당중요。분석료쌍벌조전압평형공제적책략화실현과정，침대량기분접개관도치적전압공제이상진행료분석，병결합현장실제제출개진건의，대개선계통운행유일정방조。
Yunnan-Guangdong ±800 kV DC transmission project is designed with dual 12-pulses valve groups by each pole, it's im-portant to keep the DC voltage balance between two valve groups in the same pole.The paper analyzes the strategy and process of volt-age balanced control, and two abnormal voltage control caused by tap changer.Based on maintenance at site, improvement proposal is given to improve the system's operation.
