New Algorithm of ■_0 Polarized Ground Distance Relay

Ye Ping; Chen Deshu(Huazhong University of Science and Technology Wuhan 430074 China)  
A new algorithm, double-modificatory I0 polarized ground distance protection algorithm is presented. This algorithm can effectively solve the steady state overreach problem occuring in the improved I0 polarized ground distance realy without changing the capacity of the fault resistance endurance of the relay. The results of the numerical simulation show that this algorithm is correct theoretically and it can be used in the digital distance protecting device easily.
