6-3. A 480-V 200-kW two-pole three-phase 50-Hz synchronous generator’s prime mover has a no-load speed of 3040 r/min and a full-load speed of 2975 r/min. It is operating in parallel with a 480-V 150-kW four-pole 50-Hz synchronous generator whose prime mover has a no-load speed of 1500 r/min and a full-load speed of 1485 r/min. The loads supplied by the two generators consist of 200 kW at 0.85 PF lagging.
(a) Calculate the speed droops of generator 1 and generator 2.
(b) Find the operating frequency of the power system.
(c) Find the power being supplied by each of the generators in this system.
(d) If VT is 460 V, what must the generator’s operators do to correct for the low terminal voltage?
