In a typical power plant, the production scenario and the short-circuit time were found for the worst asymmetrical short-circuit current. Then, a sensitivity analysis on the missing generator values was realized in order to minimize the uncertainty of the results. Afterward the worst asymmetrical short-circuit current was analyzed in order to compare the results with the allowable DC current component based in the IEC.

Finally the normal operating condition for the power plant was modeled.
