Adaptive Overhead Transmission Lines Auto-Reclosing Based on Hilbert–Huang Transform [PDF]

Energies, 2020
This paper presents a reliable and fast index to detect the instant of arc extinction for adaptive single-pole automatic reclosing (ASPAR). The proposed method is a simple technique for ASPAR on shunt compensated transmission lines using the Hilbert–Huang Transform (HHT). The HHT method is a combination of the empirical mode decomposition (EMD) and the

Adaptive Single-Phase Auto-Reclosing Approach for Shunt Compensated Transmission Lines [PDF]

IEEE Transactions on Power Delivery, 2021
Single-phase auto-reclosing (AR) scheme is widely employed in extra high voltage (EHV) transmission networks to quench transient faults without completely removing the faulted transmission line (TL). Long EHV TLs are commonly equipped with shunt reactors to reduce the Ferranti effect overvoltages.

Optimal negative sequence current suppression strategy without phase‐locked loop based on the control of clustered new energy power stations

IET Generation, Transmission &Distribution, Volume 17, Issue 19, Page 4248-4257, October 2023., 2023
An optimal negative sequence suppression strategy without phase‐locked loop (PLL) based on the control of clustered new energy power station is proposed. This strategy achieves effective suppression of negative sequence current during open‐phase operation without additional devices. Abstract In the context of extremely uneven sources and loads in China,

A new traveling‐wave detection method for fault location based on two sequential sliding windows and curve fitting

IET Generation, Transmission &Distribution, Volume 16, Issue 16, Page 3333-3348, August 2022., 2022
Abstract The basis of traveling wave‐based fault location methods is to extract the arrival times of transient signals in the power network. In this paper, a new method for extracting the traveling wave arrival times is presented. For this purpose, the aerial modes of three‐phase voltage signals are extracted and two sequential sliding windows of ...
