Power station 19

 Question = A power station is to supply 4 regions of loads whose peak value are 10,000 kW , 5000 kW , 8000 kW and 7000 kW . The diversity factor of the load at the station is 1.5 and the average annual factor is 60% . Calculate the ( maximum demand ) on the station and ( annual energy ) supplied from the station . ? 

Solution = according to question We are found = 10,000 + 5000 + 8000 + 7000 kW = 30,000 kW , 

» diversity factor of the load = 1.5 , 

» L.F. = 60 % , or 0.6 , 

(1) maximum demand = total load ÷ diversity factor , = 30,000 ÷ 1.5 = 20,000 kW , answer ✓ 

(2) energy generated per annum = M.D. × L.F. × Hours in a years , 

» ( 24 hours × 365 days = 8760 hours ) 

» 20,000 MW × 0.6 × 8760 h = 105120000 kWh , or ,  105.12 × 10⁶ kWh, answer ✓
