Investigation of superconducting fault current limiter application in a power-dense marine electrical network [PDF]

, 2010
Power-dense, low-voltage marine electrical systems have the potential for extremely high fault currents. Limitation of fault currents is very attractive in a marine vessel, particularly in terms of switchgear cost, size, and weight, and reducing damage ...

Application of thyristor controlled phase shifting transformer excitation impedance switching control to suppress short-circuit fault current level

Journal of Modern Power Systems and Clean Energy, 2018
Short-circuit fault current suppression is a very important issue in modern large-interconnected power networks. Conventional short-circuit current limiters, such as superconducting fault current limiters, have to increase additional equipment ...

Application of resistive super conductor fault current limiter for protection of grid-connected DGs

Alexandria Engineering Journal, 2018
Penetration of Distributed Generation (DG) into the power system causes technical problems and bad effects on the safety of the system due to increasing the short circuit levels in transmission and distribution networks. So, there will be miscoordination

Inductive Fault Current Limiters in VSC-HVDC Systems: A Review

IEEE Access, 2020
Fast emerging fault current levels in high voltage direct current (HVDC) systems has always been a significant obstacle to building a safer and more reliable grid. Inductive fault current limiters (FCLs), compared with its resistive counterpart, are very

Design of Self-Powered Solid-State Fault Current Limiters for VSC DC Grids

Frontiers in Energy Research, 2021
-Fault current limiters (FCLs) can suppress the rise of short-circuit fault currents in voltage source converter (VSC) based DC grids. However, the power electronic switches of FCLs need extra source equipment to supply the required power, which ...

Protective coordination of main and backup overcurrent relays with different operating modes of active super-conducting current controller [PDF]

Maejo International Journal of Science and Technology, 2014
Active superconducting current controllers (ASCCs) are new generation of series compensators, which can also be categorised as fault current limiters because of their ability to decrease the fault current continuously.

Asymmetrical Fault Current Calculation Method and Influencing Factors Analysis of Droop-Controlled Inverters

CSEE Journal of Power and Energy Systems
Since the fault dynamic of droop-controlled inverter is different from synchronous generators (SGs), protection devices may become invalid, and the fault overcurrent may damage power electronic devices and threaten the safety of the microgrid. Therefore,

Optimal placement of resistive superconducting fault current limiter by considering short‐circuit current and transient stability of power system

IET Generation, Transmission & Distribution, 2023
High level of fault currents has become one of the most challenging issues, along with increased electrical energy consumption and power grid expansion. However, some of the previous work was limited to installing limiters on designs and installing them ...
