A Current-Commutation DC Circuit Breaker with Adaptive Reclosing Capability [PDF]
E3S Web of Conferences, 2021 DC faults are critical events in a flexible high-voltage dc (HVDC) grid. Thus, ensuring that the power system returns to normal operation rapidly and reliably after fault isolation is very important. This requires a HVDC breaker. In overhead line systems

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,

Adaptive Single-Phase Auto-Reclosing Approach for Shunt Compensated Transmission Lines
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.

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 ...

A novel traveling wave arrival time detection method in power system
IET Generation, Transmission &Distribution, Volume 16, Issue 6, Page 1151-1165, March 2022., 2022 Abstract This paper proposes a high‐speed and accurate method for extracting the arrival times (ATs) of traveling waves (TWs) in the power system that can be used for fault location applications and transmission line protection. The proposed method is based on the expression of the traveling wave as the exponentially damped component superimposed on ...
