Two exactly similar turbo-alternators are rated 5 MW each. They are running in parallel. The speed load characteristics of the driving turbines are such that the frequency of alternator one drops uniformly from 60 Hz on no-load to 57.5Hz on full-load, that of alternator two from 60 Hz to 58 Hz. How will two machines share a load of 8,000 kW?
A3,556 kW, 4,444 kW
B4,000 kW, 4,000 kW
C3,500 kW, 4500 kW
D3,636 kW, 4,364 kW
