摘要
介绍 2 0 0 0年全国电网 2 2 0kV及以上系统线路主保护 (纵联、距离、零序、重合闸 )及微机保护运行情况 ,并结合所发生的事故进行分析 ,其目的是通过交流 ,吸取经验教训 ,防止类似事故重演 ,提高运行水平。
The operating conditions of line main protections(lognitudinal affiliation,distance,zero sequence,recloser)and microprocessor based protections for 220 kV and above systems in 2000 are introduced,and the occurred misoperations are analyzed.It is to prevent the similar faults and improve the operating level by exchanging the experience and learning the lessons.
