摘　　要：主要分析了酒湖工程韶山换流站无功控制功能、程序实现和投切策略,并结合实际运行经验,对当前无功控制程序提出了改进建议。通过优化程序设计,降低因送端配套电源建设滞后或受端负荷消纳受限导致直流系统投运后长期小功率运行情况下的事故风险,提高直流系统运行安全性,也为后续直流工程无功控制程序设计和现场运维工作提供借鉴。This paper mainly analyzes the reactive power control function, program implementation, control strategy of Shaoshanconverter station, and combined with the actual operation experience, puts forward an improved proposal to the current reactivepower control program. By optimizing the program design, it reduces the risk of accident when UHVDC system long-term lowpower operates, caused by construction of sending power lag or load given limited, improves the safety of operation. It canprovide references for reactive power control program design of subsequent HVDC project and field operation work.
