摘要
电力系统运行故障经常会引起电流互感器的稳态或暂态饱和,对继电保护装置产生不同的影响和要求。通过介绍这两种不同工况的电流互感器的饱和特性,列举宁夏大唐国际大坝发电有限公司升压站电流互感器实例进行计算,分析了这两种类型电流互感器的不同特性以及对实际工作应用的意义。
The operating faults in the power system often lead to CT steady and transient saturation, which have different effect and demand on relay protection device. Through introducing saturation characteristics of CT under two kinds of different work situation, lists the CT example of boost station in Ningxia Datang International Daba Power Generation Co.,Ltd. to calculate and explain, analyzes the different characteristic and significance in real work of the two types of CT.
