Intrinsic Time Decomposition Based Adaptive Reclosing Technique for Microgrid System
2020The conventional reclosing system generally follows the prefixed operating time to close the breaker followed by any transient fault. In a microgrid system with a storage facility, the uninterrupted power supply can be provided with the help of a storage system for a short time period.

Research on phase-by-phase adaptive reclosing sequence for transmission lines
2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019There 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

An Adaptive Auto-Reclosing Scheme to Preserve Transient Stability of Microgrids
IEEE Transactions on Smart Grid, 2018Conventional auto-reclosing algorithm (CRA) jeopardizes the transient stability of synchronous generator-based distributed energy resource (SGBDER) and, accordingly, the transient stability of entire microgrid ( $\mu \text{G}$ ). The fixed dead time associated with CRA is the origin of this deficiency.

A wavelet packet based method for adaptive single-pole auto-reclosing
Journal of Zhejiang University SCIENCE C, 2010We present a new algorithm for adaptive single-pole auto-reclosing of power transmission lines using wavelet packet transform. The db8 wavelet packet decomposes the faulted phase voltage waveform to obtain the coefficients of the nodes 257, 259 to 262. An index is then defined from the sum of the energy coefficients of these nodes.

Adaptive Single-Pole Auto-Reclosing Scheme for Hybrid MMC-HVDC Systems
IEEE Transactions on Power Delivery, 2019After the isolation of a single pole-to-ground fault, the adaptive auto-reclosing concept in high-voltage dc (HVDC) systems is difficult to be applied due to little coupling between the poles. With fault ride through capability, the hybrid modular mult-ilevel converter (MMC) can be advantageous for future HVDC projects.

Adaptive auto-reclosing based on DER connectivity data with IEC 61850
2014 IEEE PES General Meeting | Conference & Exposition, 2014Most faults in the overhead distribution networks are temporary in nature. The protection system is therefore designed to open the line in an attempt to clear the fault and then automatically reclose to reconnect the circuit once the fault has cleared.

An adaptive single phase reclosing algorithm based on the mathematical morphology
2010 5th International Conference on Critical Infrastructure (CRIS), 2010Single-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.

The scheme of single-phase adaptive reclosing on EHV/UHV transmission lines
IET 9th International Conference on Developments in Power Systems Protection (DPSP 2008), 2008Automatic reclosure (AR) is extremely effective in improving the reliability, stability and security of the overall power system. However, the present autoreclosure operates blindly and practices employing a fixed time. In the case of permanent fault, a second shock to the system can cause irreparable damage to expensive equipments.

EFFECT OF ADAPTIVE SINGLE-POLE RECLOSING ON TURBINE-GENERATOR SHAFT TORSIONAL TORQUES
Electric Machines & Power Systems, 1996ABSTRACT This paper presents the adaptive reclosing technique as a new concept to reduce the high torsional torques to which the turbine-generator shafts might be subjected during unsuccessful single-pole reclosing. In this context, investigations have been conducted on a detailed benchmark model of a one-machine infinite bus system.
