摘要
根据上海地铁2号线直流牵引供电系统继电保护的配置,结合直流保护的原理,分析直流保护动作电流的特征波形,阐述系统保护参数设置与地铁车辆负载特征匹配性问题;对比现场测试数据和保护原理的特征曲线,提出保护参数匹配的调整方法,为直流牵引系统的保护调整提供参考依据。
According to the relay setting in DC traction power system of Shanghai metro Line 2 and the theory of DC protection, the characteristic waves during tripping process were analyzed. The matching between relay protection parameters in DC traction system and characteristics of rolling stock is explained. A specific regulation scheme is put forward through contrasting the real testing data and the characteristic curves of protection principle for regulating the matching of relay protection parameters.
