Specification of fault current limitation level for FCLs in power systems

Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon), 2010
With the increasing capacity of power system, fault currents (CBs) may exceed the interrupting capacity ratings of circuit breakers. Fault current limiters (FCLs) can be applied to maintain circuit breakers within their interrupt ratings. The degree of fault current limiting on system performance is analyzed in radial and meshed system structures ...

A Fault Current Limiter Self-Adapting Activation Strategy for Flexible HVDC System Based on Fault Severity Assessment

IEEE transactions on industrial electronics (1982. Print), 2023
In the flexible HVdc system, fault current limiters (FCLs) need to be configured to reduce the rising rate of fault current. However, the FCL configured according to the bipolar near-end metallic short-circuit faults may cause the fault current to be ...

A novel fault current limiter topology design based on liquid metal current limiter

Plasma Science and Technology, 2022
Liquid metal current limiter (LMCL) is regarded as a viable solution for reducing the fault current in the power grid, but demonstrating the liquid metal arc plasma self-pinching process of the resistive wall and reducing the erosion of LMCL are ...

Air-Core-Transformer-Based Solid-State Fault-Current Limiter for Bidirectional HVdc Systems

IEEE transactions on industrial electronics (1982. Print), 2022
Modular multilevel converter (MMC) high-voltage direct current (HVdc) transmission is a promising method to integrate renewable energies. However, limiting the dc-link fault current and accelerating the fault-current clearance are critical issues for MMC-

Design Considerations of a Fault Current Limiting Dynamic Voltage Restorer (FCL-DVR)

IEEE Transactions on Smart Grid, 2015
This paper proposes a new fault current limiting dynamic voltage restorer (FCL-DVR) concept. The new topology uses a crowbar bidirectional thyristor switch across the output terminals of a conventional back-to-back DVR. In the event of a load short, the DVR controller will deactivate the faulty phase of the DVR and activate its crowbar thyristor to ...

A Bidirectional Active DC Fault Current Limiter Based on Coupled Inductor

IEEE Transactions on Power Delivery, 2022
When a fault occurs on the dc side of the voltage source converter based high voltage direct current (VSC-HVDC) transmission system, the fault current rises quickly due to the low damping of the dc system.

A 3-D Finite-Element Method Approach for Analyzing Different Short Circuit Types in a Saturated Iron Core Fault Current Limiter

IEEE transactions on applied superconductivity, 2022
In several cases, substations have become incapable of supporting faults due to increase in short-circuit levels. Fault current limiters (FCLs) are a potential solution for this problem.
