Review of the State-of-the-Art on Adaptive Protection for Microgrids based on Communications [PDF]

open access: yes, 2020
The dominance of distributed energy resources in microgrids and the associated weather dependency require flexible protection. They include devices capable of adapting their protective settings as a reaction to (potential) changes in system state ...

Adaptive Single-Pole Autoreclosure Scheme Based on Wavelet Transform and Multilayer Perceptron [PDF]

open access: yes, 2010
Adaptive autoreclosing is a fast emerging technology for improving power system marginal sta-bility during faults. It avoids reclosing unto permanent faults and recloses unto transient faults only after the secondary arc has extinguished.

An adaptive reclosing method for active distribution network based on multi-harmonic current injection by IIDG

open access: yesInternational Journal of Electrical Power & Energy Systems
The traditional auto-reclosing (AR) method based on fixed time delay cannot avoid blind reclosing on permanent faults. Moreover, with the increasing penetration of inverter interfaced distribution generations (IIDG) in the active distribution networks ...

Performance investigation of multi-level inverter for DFIG during grid autoreclosure operation [PDF]

open access: yes, 2019
This paper aims to study the multi-level inverter (MLI) fed the widely used doubly-fed induction generators (DFIG). The new DFIG generator connected to the electrical grid is evaluated during single-pole autoreclosure operation to continue the generator ...

Permanent Fault Identification Scheme for Distribution Feeders Using Detection‐Based Reclosing

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel permanent fault identification scheme based on detection‐based reclosing to mitigate the risks of blind three‐phase reclosing and overcome the sensitivity limitations of existing methods. ABSTRACT To mitigate secondary damage caused by reclosing a distribution line with a permanent fault, a highly sensitive fault property ...

A novel approach to adaptive single phase auto-reclosing scheme for EHV transmission lines

open access: yesInternational Journal of Electrical Power & Energy Systems, 2011
Abstract In modern interconnected power systems, nearly 80% of faults in high voltage transmission lines are intrinsically transient. The necessity of rapid fault clearing has resulted in fast development of protection equipments. Moreover, need for reliable supply of loads has led to improvements in single phase auto-reclosing equipments.
