超高压、大容量、远距离、西电东送、北电南送的大电网格局对输变电设备的运维与管控能力提出更新、更高的要求。与此同时，西电东送通道微地形、微气象特征明显，覆冰雪、强雷暴、飑线风等极端天气呈多发趋势，设备的安全运行风险凸显。
The large UHV power network structure characterized by large capacity, long distance, west-to-east power transmission and north-to-south power transmission has placed more new stringent requirements on the capability of operation, maintenance and control of power transmission and transformation equipments. Moreover, the west-to-east power transmission channels exhibit noticeable micro-topography and micro-meteorology characteristics and the extreme climate such as coating of ice and snow on lines, strong thunderstorm and squall line wind occur more frequently, posing more risks on the safe operation of the equipments.
