Abstract
This article presents an expansion of the superposition method for short circuit current calculations to take the voltage-dependent fault ride through behavior of power plants with a full-scale converter into account. Furthermore, it shows the physical limits of the short circuit current contribution to the grid required by the German Technical Connection Rules. Exceeding these physical limits through the short circuit current contribution of power plants with a full-scale converter leads to convergence problems of the developed iterative short circuit current calculation method. In order to identify the power plants with an impermissible short circuit contribution, the permissible operating points depending on the short circuit voltage are derived. An illustrative short circuit current calculation shows the influence of the pre-fault load flow as well as the effects of an active current feed-in during the short circuit on the initial short circuit current.
