Compound ferroresonance overvoltage and fault current limiter for power system protection

IET Energy Systems Integration, 2020
Power systems are subjected to various types of faults as well as ferroresonance overvoltages. These results in the interruption of the normal operation of the power grid, failure of equipment, electrical fires, etc.

Improvement of Protection Coordination for a Distribution System Connected to a Microgrid using Unidirectional Fault Current Limiter

Ain Shams Engineering Journal, 2017
The presence of distributed generation (DG) units in distribution systems increases the fault current level, which disrupts the existing coordination time interval of the protective overcurrent relays.

Modified switch type fault current limiter for low‐voltage ride‐through enhancement and reactive power support of DFIG‐WT under grid faults

, 2020
The sudden voltage drop may upsurge the current level and trigger the self-protective system to disconnect the wind turbines that are detrimental for grid constancy.

Research on optimal configuration of fault current limiter based on reliability in large power network

Archives of Electrical Engineering, 2020
With the availability of UHV engineering technology, the scale of the power network is expanding, and the level of the short-circuit current is getting higher, which brings hidden trouble to the safe and stable operation of the power network.

Development of TCSC Application to Fault Current Limiters

IEEJ Transactions on Power and Energy, 2001
AbstractA new Fault Current Limiter (FCL) is proposed which consists of a conventional Current Limiting Reactor (CLR) and a Thyristor‐Controlled Series Compensator (TCSC) in series. In normal operation, it works to compensate for impedance of the CLR and a line, while it limits short‐circuit currents during system faults.

Resistivity of REBCO tapes in overcritical current regime: impact on superconducting fault current limiter modeling

Superconductors Science and Technology, 2020
A detailed knowledge of the resistivity of high-temperature superconductors in the overcritical current regime is important to achieve reliable numerical simulations of applications such as superconducting fault current limiters. We have previously shown

Experimental study of a transformer with superconducting elements for fault current limitation and energy redistribution

, 2005
Numerous proposed and developed superconducting fault current limiters and self-limiting transformers limit successfully fault currents but do not provide uninterrupted supplying of consumers. A design investigated in the work combines the functions of a

Thyristor based bridge‐type fault current limiter for fault current limiting capability enhancement

IET Generation, Transmission & Distribution, 2016
This study deals with a developed thyristor based bridge‐type fault current limiter (TBFCL), in which the main fault current limiting function is relegated to a limiting circuit controlled by a silicon controlled rectifier (SCR). Since SCR is a reliable power electronic switch and can be found in high ratings, the proposed TBFCL can be utilised in ...
