Figure P.8.36 shows two generators supplying in parallel a load of 2.8 MW at 0.8 pf lagging:
(a) At what frequency is the system operating and what is the load supplied by each generator?
(b) If the load is now increased by 1 MW, what will be the new frequency and the load sharing?
(c) In part (b) which should be the set point of G2 for the system frequency to be 50 Hz? What would be the load sharing now?
