9.10 A VSC based h.v.d.c. link is connected into a 33 kV a.c. system with a short circuit level of 150MVA. The VSC can operate between 0.7–1.2 pu voltage and has a 21.8 coupling reactor. Assume a voltage of 1 pu on the infinite busbar, and using a base of 150 MVA calculate: a. The maximum active power that the d.c. link can inject into the a.c. system. b. The angle of the VSC when operating at 10MW exporting power. c. The maximum reactive power (in MVAR) that the d.c. link can inject into the a.c. system. d. The maximum reactive power (in MVAR) that the d.c. link can absorb from the a.c. system. (Answer: 45 MW; 12.8°, 7.88 MVAR, 10.4MVAR)
