What is the load curve?
The load curve is a graph used by engineers and energy manufacturers to show how many electricity customers they use in a given period of time. Looking at the graph, the time is usually placed on the horizontal axis and the load is placed on the vertical axis. This data can be used to predict trends in power, allowing areas to assemble and connect a sufficient amount of energy generators for demand periods. Types of energy generators differ depending on sources in the geographical area. The load curves can be calculated in different ways depending on the needs of electrical suppliers.
daily, monthly and annual load curves are used power plants to determine the number of generators. Look at the daily load curves for 24 hours to find the load requirements every half an hour or an hour. Monthly records the load changes during the monthly period versus the number of days recorded and the annual load curve determines changes in energy requirements within one yearVariations of load variations. The highest point on the load curve is the maximum demand at the moment. The area under the curve is the number of units that have been generated in this period.
load curve can also be calculated based on the types of power used in the system. This type of graph distributes energy distribution according to the electric demand technology used. Looking at each type of electrical technology, the graphs are much more demanding on data and work than graphs that do not decompose into such small segments, but can be useful due to increased accuracy. The load curves calculated using this method can also look at daily, annual and monthly reserves for each type of technology. Curves are sometimes prepared that decompose various segments of the population using strength, such as commercial, residential, industrial, hospitals, street lighting and entertainment.
different power plants can be throughout the roleto different ways to satisfy the demand for energy in the area. Among the types of energy generators are nuclear, steam, water turbine. The most effective energy generators are used during the highest energy demand, which is based on the information obtained from the load curve. Engineers use complicated formulas to calculate load curves, which in turn determines which way of supplying energy is best at a given moment.
