摘要
介绍了四川电网在5.12汶川特大地震中遭受的前所未有严重破坏,包括负荷、电源、线路、变电站以及城配网等各个方面的受灾情况,分析总结了受灾原因和影响灾害程度的因素,得出地震烈度超过了设防标准是本次电力系统受损的主要原因,变电设备的结构、材料以及所处地理位置的地质状况也决定了其在地震中的易损性、最后,针对性提出了提高电力系统抗震可靠性的措施。
Sichuan power grid is suffered from unprecedented damage in the 5.12 Wenchuan earthquake. Several aspects of the disaster are discussed, such as Sichuan power grid load, power supply, transmission lines, substations and the city distribution network, and the damage reasons are analyzed. The main reason of power system suffered from damage is the intensity of earthquake exceeds its bearable standards, and the structure, materials and the geographical condition of transformer equipment decide its weak earthquake resistance in the earthquake. Some earthquake protective measures are suggested to improve the earthquake resistance of power.
