Power station 4

 Question = A generating station has a maximum demand of 25 MW a load factor of 60% , a plant capacity factor of 50% and a plant use factor of 72% . find (1) the reserve capacity of the plant , (2) the daily energy produce and (3) maximum energy that could be produced daily ? , if the plant while running as per schedule where ,  fully loaded . 

• solution = is given , 

• generating station maximum demand = 25 MW ,  • L.F. = 60% , • plant capacity factor = 50 % , use factor = 72 % , 

» reserve capacity of the plant = plant capacity - maximum demand , 

» plant capacity = average demand ÷ plant capacity factor , 

» average demand = maximum demand  × load factor ,  = 25 MW × 0.60 = 15 MW , 

» plant capacity = a.d./p c.f. , = 15 MW/0.5 , = 30 MW , 

» reserve capacity of the plant = p.c. - m.d. , =  30 - 25 = 5 MW , answer ✓ 

(2) daily energy produce = average demand × 24 hours , = 15 MW × 24 H , = 360 MWH , answer ✓ 

(3) maximum energy that could be produced = actual energy produced in a day ÷ plant use factor , = 360 MWH ÷ 0.72 , = 500 MWH/day , answer ✓
