Three physically identical synchronous generators are operating in parallel. They are all

Three physically identical synchronous generators are operating in parallel. They are all rated for a full load of 120 MW at 0.8 PF lagging. The no-load frequency of generator A is 61.5 Hz, and its speed droop is 2.4 percent. The no- load frequency of generator B is 61 Hz. and its speed droop is 2.6 percent. The no-load frequency of generator C is 60 Hz and its speed droop is 3 percent. If a total load consisting of 250 MW is being supplied by this power system, what will the system frequency and power of generator A be? Select one: O A. 50.12 Hz and 83 MW O B. 50.63 Hz and 90 MW O C. 50.03 Hz and 52 MW O D. 59.79 Hz and 141 MW 59.4 Hz and 58 MW
