Adaptive auto-reclosing based on DER connectivity data with IEC 61850

2014 IEEE PES General Meeting | Conference & Exposition, 2014
Most 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.

Adaptive single pole auto-reclosing using discrete wavelet transform

European Transactions on Electrical Power, 2010
This paper proposes a new algorithm for adaptive single pole auto-reclosing (SPAR) using discrete wavelet transform (DWT). The faulted phase voltage signal is captured at a sampling rate of 2.5 kHz. The sym8 wavelet function is used to decompose the signal into level 1 and to define an index function (INDF), which is obtained from the sum of absolute ...

Design of an online adaptive auto-reclose algorithm for HV transmission lines

2006 IEEE Power India Conference, 2006
This paper proposes an adaptive auto-reclose scheme for high voltage transmission lines. It presents application of wavelet transform in identification of transient and permanent faults by processing the fault generated high frequency voltage transients. It can also be utilised to determine adaptive reclosure time with capturing arc extinction time.

Adaptive Distance Relaying for Grid-Connected Line with Consideration of Single-Phase Auto-Reclosing

Arabian Journal for Science and Engineering, 2018
In this paper, the performance of distance relay during single-phase reclosing (SPAR) period is considered. Available distance relaying schemes are affected during SPAR period as the pre-fault signals include both negative- and zero-sequence components.

Modular Hybrid DC Breaker-based Adaptive Auto-Reclosing Method for MMC-HVDC Systems

2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), 2020
In this paper, the modular hybrid DC breaker is employed to inject active pulses after fault-current interruption and arc extinction due to a pole-to-pole fault in MMC-HVDC systems with half-bridge submodules. The power electronic branch of hybrid DC breaker is made of $n$ series modules, which allows generating active pulses with a controllable ...

Traveling Wave based Adaptive Auto-reclosing and Fault Location for Three-terminal Mixed Lines

2019 IEEE PES GTD Grand International Conference and Exposition Asia (GTD Asia), 2019
This paper presents an adaptive auto-reclosing protection scheme and fault position identification technique for three-terminal mixed line system using faulted section identification (FSI) information. The mixed line system is a power transmission network containing both overhead line (OHL) and underground cable (UGC).

Auto-Reclosing Scheme with Adaptive Dead Time Control Based on Synchro-Check Principle

2020
Series compensation plays important role in smart power grid to improve power transfer capacity and voltage profiles. Majority of faults occurring in the grid are transient in nature. However, the discrimination between transient fault and permanent fault are contemporary problems in the field of distance protection of transmission line.

Simulation Analysis of Single-Phase Adaptive Auto-Reclose on UHV Transmission Lines with Shunt Reactors

2009 International Conference on Energy and Environment Technology, 2009
This paper presents a single-phase auto-reclose study of a 1000 kV AC transmission line. The technology of auto-reclose has been widely used on the transmission lines in our country. The purpose is to make the fault line re-run after the temporary fault elimination. As most of the faults are transient in nature, the auto-reclose can greatly improve the
