摘　　要：采用国际通用方法,对中国电力企业联合会可靠性管理中心所发布的电力系统元件可靠性统计数据进行了统计与分析,给出了中国电力系统元件2001-2005年的平均可靠性指标(包括发电机组、输变电设备、直流输电系统、直流系统主要可靠性指标)以及6个在运直流系统的平均可靠性指标;并针对交直流互联系统可靠性评估的特殊性,对我国当前直流系统可靠性数据的统计内容和方法中存在的一些不足进行了探讨。By using the internationally universal methods, the power system component reliability data issued by the Reliability Management Center of China Electricity Council （CEC） were analyzed and calculated, and the average reliability indices of power system components in China in recent 5 years are given, including that of the generating units, transmission and distribution equipment, and HVDC transmission systems. Considering the characteristics of hybrid AC/DC system reliability analysis, the defects in the statistical content and method for DC system reliability data are discussed, and suggestions are proposed.
