“…In the event of a fault in the DC lines in VSC-HVDC systems composed of two-level converters, the IGBT loses the ability to control and turn off in a short time, but the fault current is not interrupted since the diodes in anti-parallel feed the fault as a traditional bridge rectifier [4][5][6]. At the same time, the capacitors also feed the fault.…”

“…Thus, adopting a conservative approach, that ratio will be considered equal to one. Then, the values of and should be determined so that the value of be at least equal to (5). The effective area of the SFCL can be calculated as a function of the critical current , as shown in (7).…”

“…With advances in power electronics, this technology has been used widely in many countries across the world, especially in North America and Europe [3]. VSC-HVDC systems have advantages over CSC-HVDC systems, such as: they allow independent control of the active and reactive power flow, allow the connection of the converter to a weak AC system, employ more compact and cheaper filters, use lighter cables and, mainly, allow multi-terminal applications [4][5][6]. In this context, the advantages of VSC-HVDC systems in relation to other types of transmission systems, coupled with technological advances in power electronics are motivating researchers around the world to study these systems [1][2][3][4][5][6].…”

“…The CSC-HVDC systems have the natural ability to withstand short circuit currents in the DC lines, because of the inductors in series with the line. In contrast, VSC-HVDC systems do not employ such inductors, reducing their capability to withstand overcurrents in comparison with the CSC-HVDC technology [4][5][6]. Another issue to be analyzed for faults in the DC line is that for multi-terminal applications, the use of DC breakers is necessary, and these devices have low short circuit capability, reaching about 9 kA [4].…”

Direct current transmission based on Voltage Source Converters (VSC-HVDC) has a number of advantages compared with traditional HVDC systems. However, VSC-HVDC systems are subjected to high short circuit currents due to faults in the DC line, which may contribute negatively to the dissemination and advances of this technology. In this context, this paper analyzes the impact of superconducting fault current limiters on the system response due to faults in the DC line. An effective model for fault limiters is proposed, aiming at limiting the fault current to values below the short circuit withstand capability of DC breakers. The results show the effectiveness of the method and the advantages of using superconducting materials to minimize the impact of faults on VSC-HVDC lines.

“…A maioria dos trabalhos técnicos relacionados à proteção de linhas HVDC se referem à proteção de sistemas CSC-HVDC [27], [41] e [42]. Devido às significativas diferenças entre sistemas VSC e CSC, os ajustes das proteções das linhas CC aplicados a sistemas CSC-HVDC podem não ser adequados para sistemas VSC-HVDC.…”
