摘要: 为解决台风对电网设备破坏严重的问题,从灾害系统理论出发,界定台风电网设备灾害和要素,分析电网设备台风灾害的孕灾环境、致灾因子及承灾体的相互作用机制,揭示电网设备台风灾害的灾变路径及破坏模式,同时,集成决策试验与评价实验室(DEMATEL)分析法和解释结构模型(ISM)分析法,构建电网设备台风灾害影响因素耦合层次递阶模型。结果表明:电网设备台风灾害的典型破坏模式为机械过载、风偏闪络、冲刷腐蚀、洪水淹没、雷击过电压,主要作用对象为变压器、导线、杆塔及绝缘子;电网设备台风灾害演化过程具有明显的链式结构和层级关系,呈现出自然灾害事件链触发电网技术事故的复合灾害模式。

Abstract: In order to solve the serious destruction to power grid equipment caused by typhoon, disasters of power grid equipment and its elements were defined based on disaster system theory, and interaction mechanism of disaster-forming environments, disaster-causing factors, disaster-bearing body was analyzed. On this basis, disaster process and failure mode were revealed, and a coupled hierarchy model of influence factors of typhoon disasters was established based on DEMATEL-ISM. The results show that typhoon disasters of power grid equipment mainly destroy the transformer, transmission line, tower and insulator by the way of mechanical overload, windage flashover, erosion corrosion and flood inundation, lightning overvoltage. And their evolution process features obvious disaster chain and hierarchy relationship, which reveals compound disaster mode from natural disasters to technology accidents of power grid.

Key words: typhoon, power grid equipment, evolution mechanism of disasters, failure mode, decision making trial and evaluation laboratory-interpretative structural modeling(DEMATEL-ISM)
