Problem 2: The following figure shows a power system consisting of two parts, A and B. Bus #1 is connected to other buses of part A and bus #2 to other buses of part B. There is no connection between the two parts except through the two transmission lines shown in the figure. When the two circuit breakers a and b are open the Short Circuit Capacity of buses 1 and 2 are SCC, = 5 pu MVA and SCC, = 2.5 pu MVA. Find the SCC of each of the three buses when the circuit breakers a and b are both closed. В 2 j0.3 pu2 j0.1 pu2 3
