A voltage-clamped bidirectional fault current limiter based on a three-winding coupled inductor for DC power grids

International Journal of Electrical Power & Energy Systems
The DC fault is a serious challenge to voltage-source-converter-based HVDC (VSC-HVDC) systems, and the fault current limiter (FCL) is one of the key measures to solve the DC fault and reduce the capacity of the DC circuit breaker.

HTS materials for AC current transport and fault current limitation

IEEE Transactions on Appiled Superconductivity, 2001
The European SUPERPOLI project aims to define a MV fault current limiting power link, and to demonstrate its feasibility by a functional model. It includes the development of two alternative low-ac-loss conductor designs suitable for current limitation: a low-cost composite tubular Bi-2212 conductor with moderate Jc; and a coated tubular Y-123 ...

Novel Topology of DC Energy-Released Circuit For Saturated-Core Fault Current Limiter

IEEE Access, 2019
The saturated-core fault current limiter (SCFCL) has been studied by several scholars in the past decades. However, these studies have mainly focused on the AC coils of the SCFCL, the DC excitation has seldom been mentioned. In this paper, the DC coil of

Fault ride-through enhancement of fixed speed wind turbine using bridge-type fault current limiter

Journal of Electrical Systems and Information Technology, 2016
The interaction between wind energy turbines and the grid results in two main problems, increasing the short-circuit level and reducing the Fault Ride-Through (FRT) capability during faults.

Behavior Of Superconducting Fault Current Limiter Under Fault Condition

, 2017
Now a days due to increase in electricity demand for the purpose of industrialization, agriculture, domestic and educational etc there exists more chances of fault occurance. The Faults occurs due to insulation damaging, breaking of conductor, short circuit, lightning etc.

Improved Low Voltage Ride-Through Capability of DFIG with ESO Controller under Unbalanced Network Conditions

Majlesi Journal of Electrical Engineering
Under unbalanced grid condition, in a Doubly-Fed Induction Generator (DFIG), voltage, current, and flux of the stator become asymmetric. Therefore, active-reactive power and torque will be oscillating.

Optimal allocation of fault current limiters for sustaining overcurrent relays coordination in a power system with distributed generation

Alexandria Engineering Journal, 2015
This paper addresses the problem of overcurrent relays (OCRs) coordination in the presence of DGs. OCRs are optimally set to work in a coordinated manner to isolate faults with minimal impacts on customers.
