Producers are continuing to work on adding renewable energy in distribution network. Wind power plants are most often used as distributed generation (DG). However, every addition of DG can increase the level of short circuit current fault. To reduce this impact, a solution is needed to reduce the current fault level. The solution that can be used is Superconducting Fault Current Limiting (SFCL). The basic principle of SFCL is to increase the value of impedance in the short circuit condition, so that the current fault can be limited or reduced. In normal conditions, SFCL has an impedance close to 0. The focus of DG in this study is try to install SFCL on the four types of wind turbine power plants. In the research method, 5 scenarios are made to compare the results of each types of wind power plants. The first scenario is short circuit without DG. The second scenario, short circuit in type 1 and 2 of the wind power plant. The third scenario, short circuits on types 3 and 4. The fourth scenario, short circuits on types 1 and 3. The fifth scenario, short circuits on 4 types of wind power plants. The existence of SFCL can reduce the level of short circuit current fault significantly. SFCL can also cut or reduce the subtransient and transient periods in scenarios 2, 4 and 5. At the beginning of the short circuit, the total current fault curve only has a steady state period. This means that SFCL is able to cut the current fault level less than cycle at the wind power plant. Short circuit in FCIIG (scenario 3), since the beginning there is no sub-Transparency and transient period. © 2020 IEEE.
