Web3 mrt. 2008 · DanDel (Electrical) 3 Mar 08 12:21. The points where the busplugs are connected should be modeled as buses in the software; the busduct itself should be modeled as impedances between the buses. Don't be confused by the word 'bus' as it is used in the software; it means a connection point. The busduct is an impedance just like … Web22 aug. 2012 · Use SKM to model the fault current due to the AC sources, then add in the discharge current of the capacitors: I = (Vbus / R) * e ^ (-t/RC) For R, add the short circuit resistance, the average series resistance of the DC bus between the caps and the fault location, and the series/parallel combination of the ESR of the bus caps.
