Current Limiting Performance of Three-Phase Concentric Transformer Type SFCL at Unbalanced Fault Conditions [PDF]

, 2013
We have proposed a transformer type SFCL whose primary and secondary superconducting coils have rewound structure. The primary coil is connected to a power line. The secondary one is short-circuited and has fewer turns than the primary coil.

A modified synchronverter for a weak grid with virtual power circles‐based PQ decoupling scheme

IET Renewable Power Generation, Volume 18, Issue 14, Page 2723-2736, 26 October 2024.
A VSG is essential for ensuring stability of a power systems with high penetration of renewable energies, weak grid. Its control, however, is challenging due to the coupling of the active and reactive power which thus, requires virtual impedance. This article simplifies what type, kind and magnitude of the virtual impedance required to achieve a ...

Optimal overcurrent relay coordination: Balancing costs, time performance and generator placement in fault current limiter optimization

IET Generation, Transmission &Distribution, Volume 18, Issue 7, Page 1431-1448, April 2024.
This work investigates FCL cost minimization through the placement of the synchronous generator location within the network. This will be achieved by implementing JSO algorithm. Restoring the coordination through the FCLs without changing the directional over current relays settings is one goal of this work.

Sfcl Location Selection Considering Reliability Indices

, 2010
The fault current levels through the electric devices have a significant impact on failure probability. New fault current results in exceeding the rated capacity of circuit breaker and switching equipments and changes operation characteristic of overcurrent relay. In order to solve these problems, SFCL (Superconducting Fault Current Limiter) has rising
