  1. A power station supplies the peak load of 50 MW, 40 MW and 70 MW to three localities. The annual load factor is 0.50 p.u. and the diversity factor of the load at the station is 1.55. The maximum demand on the station and average load respectively will be
    1. 120 MW, 60.8
    2. 90 MW, 50.6
    3. 103.2 MW, 51.61
    4. 100 MW, 0.51
Correct Option: C

Diversity factor =
Sum of individual maximum demand
Maximum demand on the station

or 1.55 =
(50 + 40 + 70) MW
maximum demand on the station

∴ Maximum demand on the station =
160 MW
= 103.22 MW
1.55

Average load = load factor × maximum demand
= (0.50 × 103.22) MW = 51.61 MW
