灾害性天气对电力系统运行的影响越来越大。参考气象部门灾害性天气的预警等级划分,根据灾害天气发生地区线路跳闸后对系统的影响程度(即风险等级),将南方电网主网500 kV线路划分等级,并将线路风险等级与气象预警等级结合起来编制电力气象预警,对灾害性天气分级预警预防,在实际运用中取得较好效果。
Now severe weather endangers the electric power system strongly. According to the early-warning level of severe weather,500 kV lines of the power grid are graded based on the risk when they tripped because of the severe weather. Then,meteorological early-warning of the electric power system is issued based on the severe weather level and the line level.
