Optimal Coordination of Directional Overcurrent Relays for Microgrids Using Hybrid Interval Linear Programming - Differential Evolution [PDF]
Journal of Operation and Automation in Power Engineering, 2022 The relay coordination problem of directional overcurrent has been an active research issue in distribution networks and power transmission. In general, the problem of relay coordination is the nonlinearity of the optimization problem, which increases ...

Protection Coordination Index Assessment Using Fuzzy Logic Controller
Energies, 2022 This paper proposes the assessment method of the protection coordination index (PCI) for overcurrent protection relay and upstream relay. The protection coordination index is an indicator of how properly the equipment is protected by protective relay ...

Coordination of adaptive distance protection in transmission and wind farm collector lines under resistive fault conditions [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2020 Distance relays calculate the path impedance between the fault point and the relay location by sampling the voltage and current at the relay location. By using the ratio of the impedance estimated by the relay to the impedance of the line where the relay

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023 The optimum setting of directional overcurrent relays (DOCRs) is required to avoid miscoordination and avail fast response. To fulfill these requirements, it is required to prefer optimization techniques and modifications in objective functions (OF ...

Optimal Overcurrent Relay Coordination in Distribution Networks
2021 56th International Universities Power Engineering Conference (UPEC), 2021 Over-current relay coordination plays a critical role for effective protection of networks since primary protection is based on over-current detection in distribution systems. Thus, optimal relay coordination must be ensured between relays in faulted condition, providing selectivity and fast operation.

Coordinated Direct and Relay Transmission With Linear Non-Regenerative Relay Beamforming [PDF]
IEEE Signal Processing Letters, 2012 Joint processing of multiple communication flows in wireless systems has given rise to a number of novel transmission techniques, notably the two-way relaying, but also more general traffic scenarios, such as coordinated direct and relay (CDR) transmissions.

A temporal analysis of the swimmers’ coordination in the relay start
Sports Biomechanics, 2021 The main aims of the present research were 1) to characterise the inter-subject and intra-subject timing of the preparatory movements of competitive swimmers during relay starts and 2) to relate the preparatory movements with the relay start outcome. Nine international youth swimmers performed 10 relay freestyle starts (one-step technique) filmed at ...

2012 IEEE International Symposium on Information Theory Proceedings, 2012 In this paper, we study the problem of coordinating two nodes which can only exchange information via a relay at limited rates. The nodes are allowed to do a two-round interactive two-way communication with the relay, after which they should be able to generate i.i.d.
