Distribution System Feeder Overcurrent Protection

Considering Pilot Protection in the Optimal Coordination of Distance and Directional Overcurrent Relays

The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot protection schemes. Such schemes can be considered in the distance and directional overcurrent relays (D&DOCRs) coordination to achieve faster ...

Fault and Theft Recognition Using Toro Dial Sensor in Programmable Current Relay for Feeder Security

Feeder protection is important in transmission and distribution side because if any fault occurs in any feeder or transformer, man power is needed to identify the problem and it will take more time. In the existing system, directional overcurrent elements with load further secured by a load encroachment function can be used to provide necessary security and sensitivity for faults on remote poin...

A Review on Distribution Feeder Reconfiguration Methods

_______________________________________________________________________________________________________ _Abstract: Distribution Feeder Reconfiguration (DFR) is a critical analysis to optimize and control the distribution system and an important function of distribution automation system. Distribution feeders are configured radially. Their configurations may be varied with manual or automatic sw...

I Protection Of Power System By Optimal Co - ordination of Directional Overcurrent Relays Using Genetic Algorithm

In this paper, the optimization of coordination of directional overcurrent relays in an interconnected power system is presented. The objective of protective relay coordination is to achieve selectivity without sacrificing sensitivity and quick fault clearance time. A methodology is adopted for the consideration of backup relays in the optimal coordination of directional overcurrent relays. The...
