On a particular day, the head of Grand Coulee dam is 280 ft and the generators deliver 6000 MVA at a power factor of 0.9 lagging. Assuming the average tur- bine efficiency is 0.92 and the average generator efficiency is 0.98, calculate the following: a. The active power output [MW] b. The reactive power supplied to the system [Mvar) c. The amount of water flowing through the turbines (yd /s] Solution
