Intelligent protection coordination restoration strategy for active distribution networks

IET Generation, Transmission & Distribution, 2021
Despite various advantages of integrating distributed generation (DG) units into distribution networks such as power loss reduction and voltage profile improvement, they may disrupt the performance of the conventional protection system due to ...

Adaptive Protection Coordination for Steel Manufacturers Users

2019 IEEE Industry Applications Society Annual Meeting, 2019
This paper proposes a new adaptive protection setting methodology for steel manufacturer users considering the tap-to-tap varying current consumption. Minimizing the total clearing time of relays is computed adding the restriction of the incident energy to avoid hazard conditions.

A Coordinated Protection Strategy for Wind Integration

2018 Clemson University Power Systems Conference (PSC), 2018
High penetration of renewable energy sources (RESs) in power grid may introduce more fault scenarios due to the RES characteristics of uncertainty and variability. Based on relay protection and the coordination of relays, this paper developed a relay-based protection strategy to protect a wind turbine generation (WTG) system from short circuit ...

Overcurrent protective device coordination by computer

IEEE Transactions on Industry Applications, 1982
Overcurrent protective device coordination is defined, and the advantages of computerizing this process are explained. A computer program written by the authors, who are engineers responsible for performing coordination studies, is discussed. The program was written with emphasis on engineering flexibility.

Model of coordination for multilayer protection switching

SPIE Proceedings, 2003
Networks add recovery to deliver reliable service between a source and destination. Reliable service is an uninterrupted data transfer between nodes, even if certain links or nodes are faulty. Recovery processes in multilayer networks might operate at the same time when faults propagate between layers during a common-cause failure.

Protection coordination for networked microgrids using single and dual setting overcurrent relays

IET Generation, Transmission & Distribution, 2020
The operation of multiple microgrids (MGs) with distribution system enhances reliability and resiliency of the power supply significantly by enabling high penetration of locally available distributed energy resources (DERs).

Reverse Power Flow (RPF) Detection and Impact on Protection Coordination of Distribution Systems

IEEE transactions on industry applications, 2020
Due to the inclusion of distributed generation (DG) in modern power systems, there are certain changes in the distribution and transmission stage, either by impedance reflected by the lines, the increase of short-circuit currents, or the X/R relation ...

Protection Coordination of AC/DC Intersystem Faults in Hybrid Transmission Grids

IEEE Transactions on Power Delivery, 2020
The new characteristics and phenomena of hybrid AC/DC transmission grids challenge the conventional protection concepts. In hybrid AC/DC overhead line systems, AC and DC systems are located on the same support structure.
