摘要：

The overall damage and losses of Sichuan electric power system caused by Wenchuan earthquake were introduced. The damage situation of substations at 110 kV and above were listed, which were located in areas with earthquake intensity IX and above and managed by the state grid company in Sichuan Province. The major damage phenomena of indoor and outdoor high-voltage electrical equipments, transmission towers, distribution poles and lines were summarized. The statistics of the damage frequency, interruption situation and recovery time of substations at different levels of intensity were given. On these grounds, the Wenchuan quake damage characteristics of electric facilities in areas with intensity VI to XI, and the failure mode of electric systems were summarized. The main factors for this quake damage to the systems were analyzed. Several new measures and suggestions to strengthen the system's weakness had been put forward. The results can provide the reference for rapid evaluating the substations damage and improving the electric facilities seismic reliability.
