In previous tutorials for the MVA method, we have discussed the importance of Short Circuit Study, combining KVAs and Short Circuit Calculations for three (3) phase and single phase faults. In this part of the tutorial, we will be discussing about Load Flow and Voltage Dips during motor starting.
We shall be using the same single line diagram as in the previous tutorial, except that the 2 x 150 MVa motors at the 400V Bus are now separate. We will calculate the Load Flow and Voltage dips for starting a 150MVA motor at the 400V Bus when all loads are running.
