Correct Answer - Option 2 : Demand factor
Demand factor: It is defined as the ratio of maximum demand on the power station to its connected load.
\(D.F.=\frac{MD}{TL}\)
Where,
D.F. = Demand Factor
MD = Maximum Demand
TL = Total connected Load
The value of the demand factor is usually less than 1. It is because maximum demand is always less than the connected load. The knowledge of the demand factor is vital in determining the capacity of the plant equipment.
Utilization factor: It is the ratio of maximum demand on the power station to the rated capacity of the power station.
\(UF=\frac{MD}{RC}\)
Where,
UF = Utilization Factor
MD = Maximum Demand
RC = Rated Capacity
Diversity factor: The ratio of the sum of individual maximum demands to the maximum demand on the power station is known as a diversity factor.
\(DF=\frac{ ∑ ID}{MD}\)
Where,
DF = Diversity Factor
∑ ID = sum of Individual Demands
MD = Maximum Demand
Plant capacity factor: It is the ratio of actual energy produced to the maximum possible energy that could have been produced during a given period.
\(PCF=\frac{AD}{PC}\)
Where,
PCF = Plant Capacity Factor
AD = Average Demand
PC = Plant Capacity
