“…In other studies, the effects of using an FCL over network protection have been investigated while in Didier et al, the effects of FCL and its impedance type on increasing stability have been explained. In many articles, the effects of FCL on system reliability have been discussed . Although in the mentioned references, efforts have been made by the authors to evaluate the system reliability by using FCL, there are approximations and limitations that can reduce calculation accuracy.…”

“…These limitations are as follows: Adding any component to the system can change the system's reliability because of its failure rate. In a number of studies, it is assumed that the FCLs are completely reliable and their failure rate has been ignored in the calculations. The fault current reduction due to using FCL can reduce thermal and mechanical tensions on the network components . This may reduce the failure rate of the components .…”

Summary Limiting the fault current passing through substation components can affect their failure rate reduction. However, evaluating the exact value of the failure rate reduction is complicated. This complexity is because the fault current reduction for each component varies as fault current limiter (FCL) is installed on different substation locations. In this paper, an approach is proposed to calculate the components failure rate after installation of FCL in the substation. In this approach, an equation is derived using 3 factors consisting of the effect of fault current on failure rate, the value of fault current reduction due to FCL location, and the probability of FCL stuck. The reliability indices are calculated for 3 types of substation configurations, considering different values of active and passive FCL failure rates. In addition, the results obtained for various locations of FCL in the substation are compared to that of the case without FCL.

“…Obviously, it results in high net loss and decrease in grid stability. Superconducting fault current limiter (SFCL) techniques are gaining more and more popularity than conventional fault current-limiting methods, because the devices can limit fault current during fault period without presenting high impedance in the circuit during normal operating conditions [1], [2]. Up to now, the SFCL has experienced a rapid development, and the most important types of the SFCL contain the dc-biased iron-core type, the resistive type, the bridge type, and so on [3].…”

The application of superconducting fault current limiters in transmission systems is very attractive because the devices offer superior technical performance in comparison to conventional methods to limit fault currents. The superconducting fault current limiters show high impedance during fault period and negligible impedance in the circuit during normal operating conditions. This paper illustrates the operation performance of the active saturated iron-core superconductive fault current limiter (SISFCL) and its current-limiting effect on a transmission system. Moreover, investigations are carried out to explore the impact of the active SISFCL on the distance protection of the transmission line. Novel principle and application solutions are first proposed to eliminate the adverse effects that the active SISFCL has on the distance relay protection. A 500-kV double-circuit transmission system with active SISFCLs is simulated by using the Electromagnetic Transients Program including DC software package. Results from simulation tests have demonstrated the correctness and validity of theoretical analyses.
