Adaptive Single Phase Auto-Reclosing Using Voltage Magnitude Pattern

open access: green, 2020
This paper presents a novel adaptive single phase auto-reclosing (ASPAR) scheme based on the first derivation of local voltage magnitude (VM) of the faulted phase for determination of dead time of transient faults. The algorithm is fast and uses low-frequency sampling and adaptive threshold value (ATV).

Adaptive single pole auto-reclosing using discrete wavelet transform [PDF]

open access: bronzeEuropean 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 ...

A Time-Limited Adaptive Reclosing Method in Active Distribution Networks Considering Anti-Islanding Protection [PDF]

open access: gold
In active distribution networks (DNs), distributed energy resources (DERs) must be disconnected from the grid prior to automatic reclosing actions. Many scholars have proposed non-voltage checking reclosing methods, but a significant challenge arises ...

An Adaptive Reclosing Scheme Based on Phase Characteristics for MMC-HVDC Systems [PDF]

open access: yesIEEE Transactions on Power Delivery, 2022
To improve the reliability of power supply, reclosing schemes are required after transient faults, which commonly occur in overhead line based high voltage DC (HVDC) systems. However, in the event of permanent faults, the auto-reclosing scheme may cause a severe strike.

A capacitor-based DC circuit breaker for HVDC power grid

open access: yesFrontiers in Energy Research, 2022
DC circuit breakers (DCCBs) are the critical equipment to isolate faults in high-voltage DC grids. The improvement of interruption performances of capacitor-based DCCBs (C-DCCBs) has been widely researched.
