Short circuit study of wind/ solar plant connected to infinite bus

To calculate fault level at different buses in the plant network. How to model infinite bus generator to represent SCR and X/R ratio. Also whether short cicruit impedances are required for infinite bus generator and what to consider? Thanks in advance

Hi, in this case you would have to place a line between the infinite busbar and the following bus. With this in mind, then you would have to calculate the grid impedance by using the short circuit power and the X/R ratio at the connection point. Finally, you would have to set the calculated R and X values (in p.u.) onto the line impedance data.

Hope that helps.
