The calculation of short-circuit currents is mostly based on the methodology of the international standards IEC-60909 and ANSI / IEEE C37.010.1979. This methodology, although it utilizes simple procedures and various assumptions, usually provides satisfactory results. However, dynamic tools such as the ATP/EMTP can be used for the accurate simulation of short-circuit currents. In this paper the influence of some simplifying assumptions on the synchronous generator modeling in both standards is investigated and differences between the static and the dynamic analysis are examined, highlighting cases where significant discrepancies may occur. The analysis includes single or multiple generators connected to isolated or grid connected topologies.
