摘　　要：分析贵广Ⅰ回直流安顺换流站自双极投运以来出现的双极和双极相继闭锁事故,结合运行经验从站用电源、阀冷系统、直流控制和保护等方面提出加强运行控制、改进保护系统相关逻辑、选用合适站用电源,以及适当地提高电网的设计标准等建议。The bipolar blocked and bipolar blocked successively accidents are analyzed, which occured in Anshun converter station of GuiGuang HVDC project since October 2004 when the project was put into bipolar operation. Based on the analysis and experiences certain proposals are presented for electric source for station, valve cooling system, DC control and protection to reinforce operation control, to improve the correlation logic, to choose electric source for station, and to heighten the design standards of power grid.
