The Current-Diverting FCL-A Practical Solution to Fault Current Limiting

IEEE Transactions on Power Apparatus and Systems, 1980
This paper is intended to bring to the attention of the electric power industry a practical means for achieving the benefits of fault-current limitation. This proposed scheme circumvents fundamental problems which have thus far prevented the realization of adequate, reliable fault limiters at high power voltage and current ratings.

Fault Current Limitation by a Transformer Type FCL Based on the Second Generation HTS Wires

IEEE Transactions on Applied Superconductivity, 2011
A transformer type superconducting fault current limiter (FCL) for electric power grids was developed utilizing a nonlinear resistor made of the second generation HTS wire. Using of the second generation HTS wire instead of the first one was found to reduce by an order the required amount of superconducting materials.

Analysis of DC Fault and Current-limiting Capability of FCLs for VSC-based DC Distribution System

2019 IEEE Power & Energy Society General Meeting (PESGM), 2019
DC distribution system has received wide interests for the higher efficiency and greater operational flexibility. However, DC fault current increases rapidly, which may cause IGBTs in converters to be blocked for self-protection. Fault current limiters (FCLs) are effective to limit the fault current in DC system.

A novel improved combined Dynamic Voltage Restorer (DVR) using Fault Current Limiter (FCL) structure

2007 International Conference on Electrical Machines and Systems (ICEMS), 2007
The dynamic voltage restorer (DVR) as a means of series compensation for mitigating the effect of voltage sags has been established as a preferred approach for improving power quality at sensitive load locations. In this paper a novel structure for voltage sags mitigation and for power quality improvement are proposed.

Fault current limiting in a wind power plant equipped with a DFIG using the interface converter and an optimized located FCL

The 6th Power Electronics, Drive Systems & Technologies Conference (PEDSTC2015), 2015
Along with extending the application of Distributed Generation (DG) units attending renewable energy resources some technical problems such as protection issues are appeared. Fault level increase and inconsistency among protection elements such as relays are of these problems. Fault Current Limiter (FCL) is an appropriate choice that limits the current
