The utilization of fault current limiters (FCLs) provides an effective approach to alleviate the negative consequences associated with short circuit currents. This equipment can affect other system specifications. In this paper, the effects of FCL on power system transient stability are investigated by a theoretical-comparative study. In this study, different FCL impedances (inductive and resistive) are analyzed and compared considering two locations for FCL installation and different locations of fault occurrence in a single-machine infinite bus system. To evaluate the power system's transient stability, the authors adopt an approach based on the equal area criterion, which calculates the difference between accelerating and decelerating areas. Another issue addressed in this article is the fault-clearing time effect on the power system's transient stability as FCL is installed in the power grid. The results have been confirmed through the use of MATLAB software.
故障限流器（FCL）的应用为减轻与短路电流相关的负面影响提供了一种有效方法。该设备会影响其他系统规格。本文通过理论比较研究，探讨了故障限流器对电力系统暂态稳定性的影响。在本研究中，考虑了在单机无穷大系统中故障限流器的两个安装位置以及不同的故障发生位置，对不同的故障限流器阻抗（感性和阻性）进行了分析和比较。为了评估电力系统的暂态稳定性，作者采用了基于等面积准则的方法，该方法计算加速面积和减速面积之间的差值。本文探讨的另一个问题是，当在电网中安装故障限流器时，故障清除时间对电力系统暂态稳定性的影响。通过使用MATLAB软件，结果得到了验证。
