Three-phase adaptive reclosing method and novel fault isolation scheme for flexible interconnected distribution networks based on the soft open point

International Journal of Electrical Power & Energy Systems
The soft open point (SOP) enables flexible interconnection in distribution networks, playing an important role in enhancing the capacity of distributed energy resource integration and balancing line loads. To address the issue of secondary impacts caused

Adaptive single–phase auto–reclosing of shunt reactor–compensated transmission lines using a fundamental neutral–reactor energy (FNRE)–based index and particle filtering

International Journal of Electrical Power & Energy Systems
A substantial portion of the electrical power generated in modern power systems is transmitted through long high voltage transmission lines (HVTLs) equipped with shunt reactors; hence, providing reliable protection for these HVTLs is of paramount ...

Development of a Leader-End Reclosing Algorithm Considering Turbine-Generator Shaft Torque

Energies, 2017
High-speed auto-reclosing is used in power system protection schemes to ensure the stability and reliability of the transmission system; leader-follower auto-reclosing is one scheme type that is widely used.

An Enhanced Auto‐Reclosing Scheme for Preserving Transient Stability in AC Microgrids Based on Adaptive Dead Time

IET Smart Grid
By focussing on the limitations of fixed dead time (DT) in conventional reclosing methods, this paper highlights its significant adverse impact on transient stability of distributed energy resources (DERs) in microgrid. This vulnerability is particularly

Implementation and performance evaluation of a harmonic filter for use in adaptive single‐phase reclosing

IET Generation, Transmission and Distribution, 2017
This study presents an adaptive single‐phase reclosing method based on voltage harmonic measurement implemented in a digital harmonic filter. This filter and the transmission system were modelled in a real‐time digital simulator. A distance relay was used for protection and reclosing, responding as if it was in field operation.
