摘要
根据牵引网短路时和正常运行时电流的特点,结合电流上升率(di/dt)保护和电流增量(ΔI)保护的思想,提出了一种新的保护方案,并给出了整个保护方案的保护配置以及整定原则。
Considering current characteristics of traction network under short circuit condition and normal operating condition,and combining the methods of current-rising-rate(d i/d t)protection and current increment(ΔI)protection,this paper puts forward a novel protection scheme and gives the setting principle of each protection.
