Coordination of Directional Overcurrent Relays Using Seeker Algorithm

IEEE Transactions on Power Delivery, 2012
Coordination of directional overcurrent relays in a multiloop subtransmission or distribution network is formulated as an optimization problem. In this paper, the coordination of directional overcurrent relays is formulated as a mixed-integer nonlinear programming problem and is then solved by a new seeker optimization technique.

Directional Overcurrent Relays Coordination Scheme for Protection of Microgrid

2020 IEEE First International Conference on Smart Technologies for Power, Energy and Control (STPEC), 2020
The changes in operating states of microgrid cause significant variations in fault currents that may affect the coordination of directional over current relays (DOCRs). In this paper, an adaptive protection scheme is proposed for coordination of DOCRs in microgrids having two connection points with external grid.

Optimal coordination of directional overcurrent relays considering definite time backup relaying

IEEE Transactions on Power Delivery, 1999
A methodology is presented for the consideration of definite-time backup relays in the optimal coordination of directional overcurrent relays using linear programming. It is shown that the influence of considering second-zone distance relays and breaker failure relays impose important requirements for the determination of the time dial settings of ...

Robust coordination of directional overcurrent relays using a matheuristic algorithm

IET Generation, Transmission and Distribution, 2017
Directional overcurrent relays are often used in the protection of electrical power transmission and distribution systems. These devices are installed along the network, and they must be coordinated to operate as fast as possible and in the adequate sequence.
