2.A power station consists of four 100-MVA, 69-kV, 0.9-PF lagging synchronous generators operating in parallel with identical speed droop characteristics. The governors on the generators' prime movers are adjusted to produce a 3-Hz drop from no load to full load. Three of these generators are each supplying a steady 75 MW at a frequency of 60 Hz, while the fourth generator handles all incremental load changes on system while maintaining the system's frequency at 60 Hz.
