“…Owing to the meshed nature of the system, the network under study has situations, in which the SCFCL activates but the relay does not require setting changeover. Changing the settings for these cases solely based on the status of SCFCL, as discussed in [3, 4], may lead to malfunction of the relays. The solutions discussed in [8] will also lead to malfunction of relays.…”

There is an increase in fault current levels seen by utilities due to grid expansion and the addition of new resources. Installation of superconducting fault current limiter (SCFCL) at transmission voltage levels is being explored to reduce the fault levels. The SCFCL limits the fault current by inserting an additional impedance in the network, which may impact the protection system. This paper discusses the impacts of SCFCL on the operation of line distance protection. It is observed that operation of SCFCL may not impact all the distance relays in the substation and near-by substation in the same way, thus a boundary definition method is proposed in this study to identify the affected relays. The definitions of boundary condition based on steadystate fault current values and critical current of the SCFCL are proposed in this study. The impact of SCFCL on the line distance relays which manifest as underreaching of the relays and may also lead to coordination issues and erroneous operation. An implementation method for mitigation which is compatible with existing substation relays is proposed and demonstrated to ensure proper operation of the relays. The proposed mitigation ensures that the system integrity is maintained during faults.

“…However, if an FCL operates in a way that inserts a variable impedance, then its adverse effect on the distance relay performance is also variable. In relation to this subject, it can be found the several published studies . In Firouzi et al, the impact of BSFCL on the measured impedance by distance relay is evaluated for single phase to ground and phase to phase faults through the analytical and simulation studies.…”

“…A detailed investigation, SFCL installation location, fault type, and fault resistance impacts are the facets which have not been evaluated in this literature. The impact of HSFCL on distance relay is evaluated in, Barzegar‐Bafrooei and Foroud and a solution to enhance the performance of the distance relay in the presence of this type of SFCL is introduced in Lee et al The operation principle of HSFCL is completely different from SISFCL or BSFCL. HSFCL is the quench type SFCL and limits the fault current based on quenching the superconducting element and commutating the current to constant reactor with the help of circuit breaker.…”

“…Therefore, it is not possible to use the obtained results in related to the impact of HSFCL on distance relay for BSFCL or SISFCL. On the other hand, in Lee et al, no analytical studies have been introduced for the proposed method to improve the accuracy of the relay in the presence of HSFCL. Based on the impedance of the constant reactor applied in the structure of HSFCL and using the HSFCL operation information, the trip region of distance relay is updated to reduce the impact of HSFCL.…”

[13][14][15][16][17][18][19][20][21] In Firouzi et al, 13 the impact of BSFCL on the measured impedance by distance relay is evaluated for single phase to ground and phase to phase faults through the analytical and simulation studies. For assessments, the installation location of BSFCL is only assumed after the voltage transformer (VT) in Firouzi et al 13 The effect of double phase to ground and three phase to ground faults has not been also evaluated.…”

Summary Owing to the advance in the development of fault current limiters (FCLs) for high voltage, there is the possibility of using this equipment in transmission systems in the future. However, distance relay that is used to protect the transmission line against shunt faults, is subjected to the more direct impact of FCL installation. In this paper, the effect of the saturated iron core superconducting FCL (SFCL) and three‐phase diode bridge type SFCL on the apparent impedance seen by the distance relay, and its trip boundaries are extensively investigated. To perform the evaluations, the impact of SFCL on the measured impedance by the ground and phase distance relays is investigated through the analytical analysis. For evaluations, two possible locations for installation of SFCL including before and after voltage transformer are considered. Finally, both SFCLs are modeled in the PSCAD/EMTDC software, and the effect of each type on distance relay performance is investigated. Fault type, fault location, and fault resistance are the parameters which are considered in the simulation studies. The obtained results show the adverse impacts of both types of SFCL on distance relay performance; however, the impacts of each type are different from another. In this regard, in order to enhance the sensitivity and the security of the relay in this circumstance, the remedial action is proposed.
