摘　　要：Reliability level of HVDC power transmission systems becomes an important factor impacting the entire power grid.The author analyzes the reliability of HVDC power transmission systems owned by SGCC since 2003 in respect of forced outage times,forced energy unavailability,scheduled energy unavailability and energy utilization eff iciency.The results show that the reliability level of HVDC power transmission systems owned by SGCC is improving.By analyzing different reliability indices of HVDC power transmission system,the maximum asset benef its of power grid can be achieved through building a scientif ic and reasonable reliability evaluation system. 关键词：TRANSMISSION SYSTEMS HVDC RELIABILITY POWER TRANSMISSION SYSTEMS RELIABILITY evaluation POWER grid energy level different analyzing building benefits results ASSET
