The increase in demand for electric power and the insertion of a distributed generation led to the rise of the short-circuit current in substations. Most of these Brazilian substations were designed decades ago, because of that their equipment may not support the new short-circuit current levels. To protect the installed equipment and avoid excessive costs replacing old devices, it is possible to install Fault Current Limiters (FCLs). This document is a report from an R&D project that evaluated FCL topologies considering real parameters in simulation from used equipment, concluding that the selected FCL topologies accomplished their technical objective. However, before implementing these topologies in the distribution system, one should consider the technical and economic feasibility of using semiconductor switching devices.

Almost all of the fault current limiters (FCLs) have a negligible voltage drop during normal operation mode of the power system and show considerable impedance during the fault period. In addition, the most of the FCLs employ a reactor to limit the fault current, which carrying a DC current and named DC reactor-based FCL (DRFCL) or carrying AC current named AC reactor-based FCL (ARFCL). Here, a novel ARFCL is introduced for radial distribution networks protection. Then, the ARFCL performance on the limitation of the fault current is compared with DRFCL in a simple radial distribution network. The MATLAB software is used to simulate both FCLs performance and their effect on the fault current. The laboratory prototype of the ARFCL is built and tested for the evaluation of the ARFCL performance during normal and fault operation modes. The simulation and experimental results show the superiority of ARFCL to control the fault current, fast, and set the point of common coupling voltage in an acceptable range.

Summary The fault current level in distribution systems has increased in the last years mainly due to the energy consumption is in the limit of the production capacity and also the insertion of distributed generation, since the short circuits happen very closer to the generators now. In addition to this, most of the power substations were designed decades ago, so their equipment is overcome, and they may be damaged in a fault occurrence. To effectively protect the settled equipment or to avoid high investment costs in replacing them, one possible solution is to install a solid‐state fault current limiter (SSFCL), which may reduce the fault current to a value under the supported level. In this context, this work proposes the development of two kinds of SSFCLs: series‐switched reactor and resonant circuit. These devices were designed and compared experimentally in bench prototypes. The measurements showed that both topologies could reduce the fault current from 600 APEAK to 75 APEAK. Both SSFCL‐tested configurations were implemented using silicon controlled rectifier or insulated gate bipolar transistor. The results present the comparison between them, showing the impact in the first semi‐cycle current profile, depending on the type of semiconductor switch adopted. This article also proposes a fault detection algorithm evaluated through digital implementation in a microcontroller. The algorithm detects the fault by the instantaneous current value and its derivative, using a control strategy that avoids false detection due to measurement noises. The theoretical analysis and results are useful contributions to support the SSFCL topology choice regarding its application.
