Analysis on a Protection Scheme Based on Characteristic Variables of Current Change
Considering current characteristics of traction network under short circuit condition and normal operating condi-tion,and combining the methods of current-rising-rate(di/dt)protection and current increment(ΔI)protection,this pa-per puts forward a novel protection scheme and gives the setting principle of each protection.
