Distributed generation adverse impact on the distribution networks protection and its mitigation [PDF]

Heliyon, 2022
Integration of Distributed Generation (DG) generates problems for the protection of Distribution Networks (DNs) in power systems. When DG is integrated into a power distribution system (DS), the radial nature of the network is altered and the power ...

Fault Current Limiter Dynamic Voltage Restorer (FCL-DVR) With Reduced Number of Components [PDF]

IEEE Journal of Emerging and Selected Topics in Industrial Electronics, 2021
In this paper, a new dual function fault current limiter-dynamic voltage restorer (FCL-DVR) topology is proposed. The proposed structure, in addition to performing routine FCL tasks, can be used to improve the voltage quality of point of common coupling (PCC).

Controllable resistive type fault current limiter (CR-FCL) with frequency and pulse duty-cycle

International Journal of Electrical Power and Energy Systems, 2014
In this paper a controllable resistive type fault current limiter (CR-FCL) is introduced. The CR-FCL inserts a pre-specified value of resistance based on a pre-defined function, by using a simple switching method, in series with the fault current path. When a fault occurs, a self turn off switch starts switching with a pre-specified frequency and duty ...

Comparison of Estimated Conductor Costs between a Superconducting Thin-film Fault-current Limiter (FCL) and a Coated-conductor-based Superconducting FCL

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 2006
We recently proposed a new design for a high-temperature superconducting thin-film fault-current limiter (FCL), which uses high-resistivity Au-Ag alloy shunt layers instead of the pure gold (or silver) shunt layers conventionally used. Due to the much larger resistance of the Au-Ag alloy layers, the FCL elements withstood very high electric fields ...
