Question

PowerWorld Simulator case Problem 3.60 duplicates Example 3.13 except that a resistance term of 0.01 per unit has been added to the transformer and 0.05 per unit to the transmission line. Since the system is no longer lossless, a field showing the real power losses has also been added to the one-line. With the LTC tap fixed at 1.01, plot the real power losses as the phase shift angle is varied from -11 to +11 degrees. What value of phase shift minimizes the system losses?
