What are the differences between load curve and load duration curve?

What are the differences between load curve and load duration curve?

When the load elements of a load curve are arranged in the order of descending magnitudes, the curve thus obtained is called a load duration curve. The load duration curve is obtained from the same data as the load curve but the ordinates are arranged in the order of descending magnitudes.

How do you plot load curve and load duration curve?

The monthly load curve can be plotted using the daily load curve for a particular month. For this purpose the average load for different time for the whole month is calculated and the value thus obtained is plotted against time to get the Monthly Load Curve. Monthly Load Curve is used to fix the rate of energy.

What does load duration curve represent?

Load duration curve indicates the variation of the load, but with the load arranged in descending order of magnitude. Load duration curve give the number of hours for which a particular load lasts during a day.

What is the importance of load curve and load duration curves in relation to power plants?

Information Obtained From Load Curve Load duration curve determines the load variation during different hours of the day. It indicates the peak load which determines the maximum demand on the power station. The area under the load curve gives the total energy generated in the period under consideration.

What is load curve?

The graph which shows the variation of load on the power station with respect to time is called the load curve of the power station. The load on a power station does not remain constant; it changes from time to time.

What is load duration?

Click to enlarge. All of this relates to the idea of load duration, which is the accumulated amount of time during the life of the building that loads will be applied. All of these loads are relative to “normal” loading, which is defined as a “10-year load duration.”

What is meant by load curve?

In a power system, a load curve or load profile is a chart illustrating the variation in demand/electrical load over a specific time. Generation companies use this information to plan how much power they will need to generate at any given time. A load duration curve is similar to a load curve.

How the load curves and load duration curves can helpful in the economics of generation?

Load curve decides the installed capacity of a power station. It is helpful in choosing the most economical sizes of the various generating units. The load curve estimates the generating cost. It decides the operating schedules of the power station, i.e., the sequence in which the different generating units should run.

What are the types of load curve?

Three types of typical daily load curves in different seasons: (a) residential load; (b) commercial load; and (c) industrial load.

What are load duration factors?

Load Duration Factors allows us to increase the load carrying capacity of wood based on how long a load is expected to act on a structure–the shorter the period of time, the higher the allowed increase. Load Duration Factors are applied to the capacity or resistance of the member, not to the loads on the member.
