| 摘 要： | 随着全球气候特征的明显变化及江苏工业经济的高速发展,江苏电网设备因气象灾害所引发的故障呈现逐年递增的态势,污闪、风偏等故障次数明显增多.在广泛调研收集资料的基础上对江苏地区典型气象条件的时空分布、气象灾害形成原因进行统计分析,得出大风、雷暴、雾霾、覆冰天气条件下电网设备的故障特征,明确了故障时的主要气象要素及影响规律;同时结合江苏电网运行经验和目前采取的防御措施,提出加强电网设备抗灾设计、采用防灾新技术、建立电网灾害监测及预警系统的总体防御思路,可为具有类似气象灾害的电网设计、运行及事故预防提供重要参考.

| Abstract: | With the obvious change of global climate characteristics and rapid development of industrial economy,the number of faults on grid equipment in Jiangsu Power Grid caused by meteorological disasters is showing an increasing trend year by year,especially the contamination flashover faults and wind deflection faults.On the basis of extensive investigation,this paper presents the fault characteristics of power grid equipment under wind,thunderstorm,haze or ice.And furthermore it pinpoints the main meteorological elements and the related influence law.Combining with the existing operation experience and prevention measures,this paper gives the overall defense advice for power grid against meteorological disasters,including improved design and plan of power grid equipment,employment of new technology,meteorological disaster monitoring and warning system.The results above can provide important reference for the designing,maintaining and fault prevention of power grids with similar meteorological conditions. |
