“…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.…”

“…This may reduce the failure rate of the components . In a number of studies, the effect of FCL on the failure rate reduction of other components has been ignored. Location of FCL and also fault position at the substation can affect the amount of fault current passing through the components. Therefore, depending on the FCL location in the substation, failure rate reduction of components is different.…”

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.

“…Although FCLs can have many benefits, these benefits are dependent on the number, location, and impedance of FCL. Thus, from point of view of design and operation of the power system, it is necessary to find a method that can help determine optimum number and optimum location for the installation of the FCL .…”

Summary Connection of distributed generation to the grid and the expansion of transmission system in order to meet the growing for electricity are causing the extent and complexity of the network structure. The occurrence of fault in such networks leads to flow large short circuit currents through the system, which may exceed the rating of existing circuit breakers and can damage system equipment. The utilization of fault current limiters (FCLs) in power systems can be an effective method to limit fault currents. FCLs can offer many benefits, but these benefits depend on the number, installation location, and impedance of FCL. In this paper, determining the number, location, and impedance of FCLs in network is modeled as a new optimization problem when objective functions are reliability, power loss, and economical use of FCLs. Also, a combination of discrete and continuous particle swarm optimization algorithm is employed to solve problem. Modified RBTS 2 bus test system is considered to evaluate the effectiveness and feasibility of the proposed method. Obtained results show the importance of finding optimum number, location, and impedance of FCLs in minimization of the proposed objective functions. Copyright © 2014 John Wiley & Sons, Ltd.

“…Thus existing equipment can still be used to protect the power system [1][2][3]. In recent years, various types of FCLs, such as the solid-state FCL, Is limiter, resonant circuit, and superconducting FCL (SFCL), have been proposed and developed [2][3][4][5]. SFCLs offer a solution to these problems with many significant advantages.…”
