Reclosing during a permanent fault subjects the transformer to secondary impacts， thereby increasing the likelihood of transformer damage. In this paper， a computational model for calculating the leakage magnetic field of a three-winding transfor

Abstract The automatic reclosing strategy is an effective measure to improve the reliability of a distribution network. It can quickly clear instantaneous faults in the grid. The traditional transformer has proven to be reliable and robust during the

Multi-terminal flexible high-voltage-direct-current (HVDC) transmission and DC grid technology are developing rapidly, and the hybrid DC circuit breaker (DCCB) is usually used to protect the DC system, which can quickly remove the fault current and m

Abstract A fault identification scheme for protection and adaptive reclosing is proposed for a hybrid multi-terminal HVDC system to increase the reliability of fault isolation and reclosing. By analyzing the "zero passing" characteristic of current a

This paper proposes a novel two-stage adaptive reclosing mechanism for shunt-compensated extra-high-voltage transmission lines. In the first stage, secondary arc extinction peak-based criterion (SAEPC) is established to monitor the precise instant of

Wind turbines are vulnerable to negative sequence current injection, the conventional automatic reclosing scheme for wind power outgoing lines, since we may inject negative sequence components into the system and reclose it without distinguishing the

With the rapid load growth and the increasing density of power grids， the overrun short-circuit current becomes increasingly aggravated. To accurately assess the short-circuit current level of the system is crucial to ensure the safe and stable ope

DC circuit breaker is the core equipment for the safe operation of DC transmission system. A current limiting hybrid HVDC circuit breaker topology with reclosing function is proposed in this paper. The topology makes use of the symmetry of current li

Precise knowledge of secondary arc extinction instant and fault nature (temporary or permanent) is necessary for auto-reclosing after a single line-to-ground fault. Existing intelligent reclosing schemes rely on the extraction of appropriate features
