Example 3/A power station has a daily load cycle as under :260 MW for 6 hours ; 200 MW for 8 hours: 160 MW for 4 hours, 100 MW for 6 hours. If the power station is equipped with 4 sets of 75 MW each, calculate (1) daily load factor (2) plant capacity factor and (3) daily requirement if the calorific value of oil used were 10,000 kcal/kg and the average heat rate of station were 2860 kcal/kWh. (1)70.50 % (2) 61.1%, (3) 1258.4 tons
