A novel adaptive auto-reclosing scheme for transmission lines with shunt reactors
Electric Power Systems Research, 2019Abstract In this paper, a novel adaptive single-phase auto-reclosing method for high voltage transmission lines with shunt reactors is presented. The proposed method applies a low-pass filter and the cascaded delayed signal cancellation (CDSC) technique to the fault phase voltage in order to reveal different characteristics between transient and ...

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.

Abstract This study describes the hardware implementation of a fast adaptive single-phase auto reclosing algorithm based on voltage harmonic content measurement. The proposed algorithm classifies the fault type, preventing reclosing onto permanent fault, and identifies the arc extinction instant, adjusting dead-time to implement reclosing with ...

Adaptive Distance Relaying for Grid-Connected Line with Consideration of Single-Phase Auto-Reclosing
Arabian Journal for Science and Engineering, 2018In 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.

Auto-Reclosing Scheme with Adaptive Dead Time Control Based on Synchro-Check Principle
2020Series 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.

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), 2019This 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).

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

IEEE Transactions on Power Delivery, 2020
Difficulties in identification of the fault property, for a fault on a single outgoing line of windfarm, arise due to rapid decrease in the electromagnetic energy of the transmission line after the tripping of three-phase breaker. An active solution to such problem is proposed based on low current injection from parallel connected static synchronous ...

IEEE Power Engineering Review, 2001
This paper presents a new concept, based on variable dead time control, in adaptive single pole auto-reclosing (SPAR). The proposed scheme can give rise to a high rate of successful reclosing by adapting to variable dead times. The significance of this algorithm is that it uses the waveform patterns of the voltage transients following initial breaker ...
