Load curve is the graphical representation of load with respect to the time in chronological order. It shows the variation of load on the power system over a particular period of time from a particular source. The load curve of the power system is not same all the day. It changes from day to day and season to season
Information Load Curve Carry
- Load curve determines the load variation during different hours of the day.
- It indicates the peak load or maximum demand on the power station.
- The area under the load curve indicates the total energy during the particular period.
- The area under the load curve divided by the total number of hours gives the load.
- The ratio of area under the rectangle to the total area of the curve gives the load factor.
Utilization of Load Curve
The main utilization of load curve has been listed below.
- Load curve decides the installed capacity of power station.
- Load curve helps in choosing the most economical size and numbers of various generating unit.
- Load curve helps to estimate the generating cost.
- Load curve ensures efficient power generation.
- Load curve decides the operating sequence of the generating unit in a power station.
Types of Load Curve
Load curve can be classified into three types according to time duration which are listed below.
- Daily Load Curve
- Weakly Load Curve
- Monthly Load Curve
- Annual Load Curve
Load curve can be classified into two types according to seasons which are listed below.
- Summer Load Curve
- Winter Load Curve
Load curve can also be classified into two types according to use which are listed below.
- Industrial Load Curve
- Residential Load Curve
