Impact of Copper Stabilizer Thickness on SFCL Performance with PV-Based DC Systems Using a Multilayer Thermoelectric Model

Utilizing renewable energy sources (RESs) to their full potential provides an opportunity for lowering carbon emissions and reaching a state of neutrality. DC transmission lines have considerable the integration RESs. However, faults in are challenging due lack zero-crossing, large fault current magnitudes short rise time. This research proposes using superconducting limiter (SFCL) effective limitation PV-based systems. To properly design SFCL, present work investigates effect copper stabilizer thickness on SFCL performance by accurate multilayer thermoelectric model. In MATLAB/Simulink platform, has been modeled tested different thicknesses demonstrate effectiveness model limiting impact SFCL’s performance. total, four were considered, ranging from 10 μm 80 μm. The voltage profile each evaluated compared with that without SFCL. developed resistance temperature profiles obtained various clarify mechanisms behind stabilizer-thickness impact. An µm can reduce 5.48 kA, representing 71.16% prospective current. contrast, was reduced 27.4% (2.11 kA) when stabilizer.
