New smart multi-ended differential solution for power networks
2018
The Journal of Engineering
Line current differential protection is based on Kirchhoff's current law calculating the vector sum of the currents from each line end to detect faults in the protected zone. For synchronisation of the current vectors, time compensation with a pingpong measurement of the propagation time delay is used. A new smart multi-ended differential protection is presented in this study, which includes a new capacitive current compensation technique. The protection relay is scalable for any transmission
