Unformatted text preview: 12 max ? B. Instead of series compensation add phase angle control, again to increase P12 to 800MW. What phase, does the compensator need to produce (assuming we can create such a precise angle? Lets say that max =30 o , what is P 12max ? BUS 1 V 1 = 345kV LL at 0 o BUS 2 j60 ohm V 2 = 345kV LL at 17.605 o Compensator ECE 529 Utility Applications of Power Electronics Session 37, Page 2/2 Spring 2009 Problem 3: Given a Delta connected load on a 69kV system with the unbalanced impedances given below. Find currents a STATCOM must provide to make the loads unity power factor (assume balanced voltage) using the instantaneous reactive power method to calculate them.
