題組內容

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.

申論題內容

(b)Calculate the new system frequency if the system load rises to 290 MW. (10%)
