Data:
Straight line load duration curve Maximum demand = 340 x 103kW , Minimum demand = 90 x 103 kW,
Installed capacity = 200 x 103 kW of 01Nos, & 120 x 103 kW of 02Nos,
To find :i) Installed capacity ii) Plant Factor iii) Load Factor iv) Utilization factor.
Plant Installed capacity = 200 x 103 x 01 + 120 x 103 x 02
= 200 x 103 + 240 x 103 = 440 x 103MW
Total Energy Generated/year = Area Under the curve AB
= Area of Triangle ABC + Area of Rectangular EDBC
= (90 x 8760) + (0.5 x 8760 x (340 – 90))
= 1.8834 x 109 kWh
Average load = (Totalenergygeneratedperyear)(Timedurationofyear)
= (1.8834×109)8760
= 215000 kW
Plant factor = (Total energy generated per year)/(Time duration of year ×Plant installed capacity) = Load factor x Utilization factor
= (1.8834×109)(440×103×8760)
= 0.4886
OR
48.86 %
Load Factor = (Averageload)(Maximumloaddemand)
= 215000340000
= 0.6323
OR
63.23%
Utilization Factor = (MaximumdemandonPlant)(PlantInstalledcapacity)
= (340×103)(440×103)
= 0.7727
OR
77.27%
