Two 60MVA, alternators operate in parallel. The setting of the governor are such that the rise in speed from full load to no load is 2% in one machine and 3% in the other, the characteristics being straight lines in both cases. If each machine is fully loaded when the total load is 120MW, what will be the load on the first machine (with 2% speed regulation) when the total load is reduced to 80MW?
