Superconductor fault current limiter (SFCL) is an effective device to suppress high fault currents. This paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  Appropriate location and type of the limiters in a HV substation is selected by a qualitative approach based on the equal area criterion. Study system is simulated by...

The application of flat superconductor rings has been investigated in the structure of inductive shieldtype high temperature superconducting fault current limiters, HTc-SFCL. A laboratory scale inductive shield-type HTc-SFCL has been designed and fabricated using flat superconductor rings. The fabrication process has been fully presented. YBCO powder has been used for the fabrication of superco...

Owing to the increasing penetration level of distributed energy resources (DER) and direct current (DC) load, usage low-voltage (LVDC) systems has expanded achieve efficient operations. However, because LVDC system reaches peak fault at a faster rate than alternating (AC) system, solution that protects components is necessary maintain integrity. It required by ride-through (LVRT) DERs their int...

The increase of current uniformity along a resistive type superconductor fault limiter (R-SFCL) in the design this limiters is well perceived as an important issue. non-uniform distribution R-SFCL only increases some superconducting regions, result, conditions, certain parts undergo phase change that heat pressure those areas and causes breakdown destruction device. In paper, density distributi...

In this paper, authors present a comparative study of inductive and resistive superconducting fault current limiters (SFCL) from current limitation and power system transient stability point of view. Different types of SFCL can be used to decrease the amplitude of fault current in a power system. The two most used are resistive type (rSFCL) and inductive type (iSFCL). However, no studies have b...

As the energy demand increases due to developing electric power industry, fault current becomes higher during time. A new approach is needed reduce a in distribution system, since currents influence other protective devices’ operation. To decrease current, superconducting limiter (SFCL) has been suggested. The SFCL no loss with effect on system because impedance only occurs However, can current...

With the development of a distributed generation, direct current (DC) load and energy-storage equipment, voltage-source-converter-based medium-voltage DC systems (VSC-MVDC) have attracted more attention due to its low power consumption, high reliability, independent control so on. However, VSC-MVDC has problem fault isolation, which requires fast-acting circuit-breakers isolate faulty lines ens...
