Figure 3.   Demand interval illustration

On the left are actual historical electricity demand data. On the right are projected data. The component uses the two data sets across a 15 minute demand interval to calculate the Projected Demand Average. In this example, the Percent Interval Elapsed property is set to 67. This causes the actual minutes elapsed over the 15 minute demand interval to equal 10 minutes and the minutes remaining to equal five minutes. The component averages the actual historical demand data over 10 minutes and uses the instantaneous demand taken at minute 11 to calculate an average projected data value for the remaining third of the period. Using these two numbers, it calculates the Projected Demand Average.

You configure Percent Interval Elapsed on the property sheet of the ElectricalDemandLimit component.
