A Novel Overcurrent Suppression Strategy during Reclosing Process of MMC-HVDC

Applied Sciences, 2019
A modular multilevel converter based high-voltage DC (MMC-HVDC) system has been the most promising topology for HVDC. A reclosing scheme is usually configured because temporary faults often occur on transmission lines especially when overhead lines are ...

Enhancing stability of Photovoltaic-Energy storage-Direct current-Flexibility power system with a novel integrated Superconducting Magnetic Energy Storage-Fault Current Limiter (SMES-FCL)

Journal of Physics: Conference Series
Abstract In order to enhance the stability and reliability of the Photovoltaic-Energy storage-Direct-Flexible (PEDF) system, a novel line-compensation superconducting magnetic energy storage-fault current limiter (SMES-FCL) was designed to address voltage fluctuations and fault current limiting issues.

Design and Experimental Study of a Novel Fault Current Limiter

, 2010
Limiting the short-circuit current effectively is of great importance to keep the safe and steady running of the power system. A novel fault current limiter (FCL) on the basis of a high speed switch and a triggered vacuum switch (TVS) is presented.

OVERCURRENT RELAY COORDINATION IN DISTRIBUTED GENERATION WITH FAULT CURRENT LIMITER

, 2017
The distribution network has many advantages when it is connected to distributed generation (DG). Some problems in coordination of protection devices will occur in the presence of DG, due to change in short circuit level at different points.
