High speed protection of medium voltage DC distribution system using modified mathematical morphology

open access: yesIET Renewable Power Generation, Volume 16, Issue 14, Page 3134-3148, 26 October 2022., 2022
Abstract One of the challenging issues in the realization of medium‐voltage DC (MVDC) distribution system is high‐speed protection scheme design against quickly rising short circuit fault‐DC current. This paper proposes a high‐speed protection scheme based on the processing of energy signals through mathematical morphology (MM). The voltage and current

An optimal phase control method for the suppression of phase sequence exchange impulse current and voltage

open access: yesIET Power Electronics, Volume 15, Issue 5, Page 412-421, 8 April 2022., 2022
Abstract Phase sequence exchange (PSE) is an emerging emergency control method for power systems. However, PSE will generate impulse current and voltage. In this research, to suppress the impulse of PSE, a phase control method for zero‐current opening and equal‐voltage closing is adopted, and verified via both physics and experiments.
