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.

Design of an online adaptive auto-reclose algorithm for HV transmission lines
2006 IEEE Power India Conference, 2006This 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.

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 Auto-Reclosing and Active Fault Detection of Lines Emanating From Wind Farms in Microgrids
IEEE transactions on energy conversionMost line faults in microgrids are temporary and are cleared shortly after the fault inception using an auto-reclosing (AR) scheme. However, there are limitations to the AR activation in generation-ended lines of microgrids because reclosing on a ...

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 adaptive single-pole reclosing technique for EHV/UHV transmission lines
2008 Third International Conference on Electric Utility Deregulation and Restructuring and Power Technologies, 2008The character of the voltage at the end of the opened phase conductor was studied and an improved voltage criterion was proposed to distinguish between transient and permanent faults. The performance of the improved criterion is hardly influenced by the load currents of healthy phases, transmission line length, fault distance and fault earth resistance.
