“…The analysis of the impacts of SFCL on the power system and vice versa, the impact of the power system parameters on SFCL performance are the important aspects of these evaluations. Albeit, it has been performed meritorious studies in both terms, [15][16][17][18][19][20][21][22][23] but in the second term, 1 of the fields that have been less considered in the previous studies is the effect of fault resistance and the position of fault on the fault current reduction ratio (FCRR) of SFCL. FCRR is defined as the ability of SFCL to limit the fault current.…”

Summary Superconducting fault current limiters (SFCLs), as the novel power system devices, have attracted attentions in the last years. However, in order to achieve the maximum benefit from SFCLs, their interaction with power system should be comprehensively evaluated before equipping the power system with them. This paper investigates the effect of fault resistance and fault distance on the steady‐state fault current reduction ratio (FCRR) of hybrid SFCL. Based on the equivalent circuit model, analytical studies are presented to obtain the relation between 2 abovementioned factors and the FCRR of hybrid SFCL. Then, through the detailed simulation studies, the current limiting behavior of hybrid SFCL is evaluated when the value of fault resistance and the position of fault change in wide range. As a result, although the hybrid SFCL is able to reduce the fault current under different circumstances; however, FCRR significantly varies under outside the control changing circumstances. For far faults and faults with high fault resistance, the FCRR of hybrid SFCL is not as good as the other fault conditions. Hence, in the last section of the paper, the remedial actions to enhance the performance of hybrid SFCL during these conditions are proposed.

“…In addition to the short-circuit current limitation, several studies have shown that the use of SFCL in an Electrical Power Grid (EPG) allows to improve the transient stability of generators and consequently the global stability of the network [5] [6]. Several papers deal with the study of iSFCL [7,8] or rSFCL [9,10,11,12,13] or the both [14,15] either in term of current limitation, or transient stability study. Kozak and al in [16] compare the two types of SFCLs experimentally but concentrate only on the decrease of the fault current.…”

International audienceIn 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 been done to show the difference between them in term of current limitation and transient stability on a same power system. We propose here to compare rSFCL and iSFCL when a fault occurs in a simple high voltage (HV) power system (IEEE 3 bus test system). To evaluate the impact of SFCL in the studied power system, time domain approach is used to evaluate the short-circuit current in the electrical power system by solving the differential equations of such circuit configuration for various SFCL impedance. For the transient stability study, authors use an approach based on the equal area criterion to evaluate the critical clearing angle (CCA) and a time domain approach to evaluate the critical clearing time (CCT) for the two types of SFCL. Results show that the two SFCLs have different impacts on the power system. However, the resistive SFCL appears to be the more suitable to limit the fault current and to increase the transient stability of the power system in case of short-circuit
