A Dual-Stage Solid-State Fault-Current Limiter for Flexible DC Distribution Networks

IEEE Transactions on Power Delivery
For limiting fault currents, accelerating fault-clearance speed, and providing protection for converters with weak transient-stress tolerance, a dual-stage solid-state fault-current limiter (FCL) is proposed, whose main module is based on thyristors ...

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

A Voltage-Clamping Type DC Fault Current Limiter With Low Power Losses

IEEE transactions on power electronics
Fault current limiters (FCLs) have high impedance during fault conditions. However, it is inevitable to introduce additional impedance to the system, which may increase power losses, cause overvoltage, and degrade system dynamic performance.
