Q1) A distribution substation bus supplying two loads, Customer 1 and Customer 2 is shownin Figure 1. The utility specifies a 30-minute demand interval. Assume there are 730hours in a month.TISubstation20 MVAbusCustomer 16% X30-min Dmar- 15 MW/ monthEnergy use - 500 MWh / monthTotal connected demand = 18 MWSCC = 100 MVACustomer 2T210 MVA2% XFigure 1(a) Determine the demand factor, load factor and utilization factor for Customer 1.(b) Suppose a three-phase short circuit fault occurs at Customer 2. Calculate the percentagevoltage dip experienced by Customer 1. Use a power base of 50 MVA in yourcalculations.(c) To reduce the impact of voltage dip in part (b), Customer 1 is given three options toconsider:i Connecting a similar transformer in parallel to TI.ii. Connecting a similar transformer in parallel to T2.iii. Connecting a new generator rated 50 MVA, 2% X at substation bus.Indicate which option will help to reduce the impact of voltage dip at Customer 1.Justify your answer.

Since each part contains multiple subparts, so we will solve all subparts of part (a) only. To get…
