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.

“…Hence, there is growing need for an accurate analytical model of the FCL, which can be easily incorporated into transient network simulation packages. The development of an accurate analytical model has already received some attention [6], [7]; however, the models developed to date do not include the AC to DC coupling effects of the device. It has been found that a "transformer" coupling effect exists between the AC and DC windings during a fault [5], which can have a significant impact on the performance of the FCL.…”

A saturated core fault current limiter (FCL) is a device that is designed to limit the fault currents in electrical energy networks and consequently, protect existing network equipment from damage. Due to complex nonlinear magnetic properties, the performance of saturated core FCLs has largely been characterized through experimentation and finite-element analysis simulations. Although both of these techniques are quite accurate, they are time consuming and do not describe the behavior of FCLs in actual electrical networks. This has led to an increasing demand for an accurate analytical model that is suitable for transient network analyses. This paper presents the development of an analytical model of a single-phase open-core FCL, which accurately describes the nonlinear magnetic properties of the FCL through a reduced reluctance approach. The extension of this model to other saturated core FCL arrangements (such as closed core) is also discussed. © 1986-2012 IEEE.

“…Several solutions and techniques for limiting fault currents have been proposed in the past such as upgrading fast circuit breakers, system reconfiguration, installing transformers with higher impedance, current limiting fuses, air-core reactors, etc. [1]- [3]. However, those methods were practically limited due to high estimated costs, lack of system security and reliability.…”

As the electrical power grids are extending in capacity with connection of distributed generations, the fault current level is increasing and approaching the capacity limits of the circuit breakers. In this paper, a saturated inductor fault current limiter (FCL) based on permanent magnet biasing has been developed to overcome the inherent disadvantages associated with many previous technologies such as superconducting based techniques. A 3D Finite Element Modeling (FEM) is used to develop and validate the proposed design and compared it with air-cored inductor. A lab-scale prototype was built to verify the design. Furthermore, a scaled up model which could be introduced to 11 kV network is introduced and its electromagnetic performance is evaluated.
