摘　　要：直流输电损耗是直流输电的重要技术和经济指标,主要包括换流站损耗、直流线路损耗和接地极系统损耗。分析了南方电网直流输电损耗系数k,认为双极平衡方式下k值最小,输送功率对直流输电损耗有直接影响,并探讨了南方电网西电东送交直流输电通道功率优化分配方法,以降低输电总损耗。As an important technological and economical index, the HVDC transmission loss includes substation loss, line loss, and grounding system loss. The transmission loss coefficient k in Southern Power Grid （CSG） is analyzed. It is considered that under bipolar balance mode, the value ofk is the smallest, and the amount of power flow directly affects the HVDC transmission loss. A tentative exploration is discussed on how to optimize the AC ＆ DC power flow in CSG to reduce the total transmission loss.
