国家电网公司直流输电系统电量消/损耗情况分析

Analysis on Power Consumption and Losses of HVDC Power Transmission Systems of State Grid Corporation of China

直流输电系统电量消/损耗情况反映了直流输电系统节能降耗水平和运行经济性。文章依据国家电网公司所属超高压直流输电工程2006—2009年4月的实际运行数据,对换流站站用电量和系统损耗电量等指标进行了分析,探讨了直流输电系统电量消、损耗与直流输电量及环境温度等因素之间的关系。

Power consumption and losses of HVDC projects reflected the level of energy conservation and operation economy. Based on the actual operational data of HVDC projects that subordinates to SGCC in recent years, statistical analysis on such indices as power consumption of converter station and losses of HVDC system has been done. It＇s fotmd that the power consumption and losses are closely related to the transmitted DC power and ambient temperature.
