Adaptive reclosing strategy for the mechanical DC circuit breaker in VSC-HVDC grid

, 2021
The overhead line has wide application prospect in the future VSC HVDC grid. However, compared with the dc cable, the fault probability (especially the nonpermanent fault), is much higher on the overhead line.

Adaptive reclosing strategy for single outgoing line of converter-interfaced wind park using distance relaying algorithm

, 2021
The 110 kV single outgoing line powered by wind generation usually adopts tripolar tripping and three-phase auto-recloser. The electrical quantities of the single line attenuate quickly after fault tripping, which makes it difficult to identify fault ...

Adaptation of superconducting fault current limiter to high-speed reclosing

Physica C: Superconductivity, 2009
Abstract Using a high temperature superconductor, we constructed and tested a model superconducting fault current limiter (SFCL). The superconductor might break in some cases because of its excessive generation of heat. Therefore, it is desirable to interrupt early the current that flows to superconductor.

Research on phase-by-phase adaptive reclosing sequence for transmission lines

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
There is no feasible method can be used to discriminate between permanent fault and transient fault after the three phase circuit breakers are tripped. Randomly reclosing onto a permanent fault may have a negative impact on the system. For the purpose of solving this problem, a phase-by-phase adaptive reclosing sequence for single-phase grounding fault

Communication-Aided High-Speed Adaptive Single-Phase Reclosing

IEEE Transactions on Power Delivery, 2013
A new communication-aided high-speed single-phase reclosing algorithm is proposed in this paper for transposed transmission lines based on predicted and measured voltage of faulted phase. Analytical analysis based on the distributed line model is performed to derive an equation which can be used to predict the faulted phase voltage after arc extinction

An Adaptive Reclosing Scheme for All-Parallel Autotransformer Traction Network of High-Speed Railway Based on Multisource Information

IEEE Transactions on Transportation Electrification
In high-speed railway (HSR), directly reclosing a circuit breaker after a fault trip can result in a large second overcurrent, causing insulation degradation, equipment damage, and even system instability.

An adaptive single phase reclosing algorithm based on the mathematical morphology

2010 5th International Conference on Critical Infrastructure (CRIS), 2010
Single-phase Auto-reclosing (SPAR) is widely used on EHV/UHV transmission lines to improve power system reliability. However, reclosing on to a permanent fault can adversely affect the system stability and damage generators and other equipment connected to the line.

Effect of adaptive reclosing on turbine-generator shaft torsional torques

IEEE Transactions on Power Systems, 1994
This paper presents the adaptive reclosing technique as a new concept to reduce the high torsional torques to which turbine-generator shafts might be subjected during high-speed reclosing of multi-phase power system faults. In this context, investigations have been conducted on a large turbine-generator model for various multi-phase faults.
