8-1 Demand measurement
The following is an example of power management by monitoring the demand.
● Reducing the average power during a specific interval
Assume the interval to be 30mins.
In the figure below, the average power during Interval 1 is assumed to be 500kW and during Interval 2
is assumed to be 600kW.
(kW)
600kW 600kW
500kW 500kW
0 15 30 15 30(min.)
Now, assume that the average power during the first 15 min. (the inspection cycle) of Interval 2 is
600kW. The average power during Interval 2 can be maintained at 500kW (same as Interval 1) by
reducing the power of the last 15 min. to 400kW.
(kW)
600kW
500kW 500kW
400kW
0 15 30 15 30(min.)
If say, the average power during the first 15 min. is 1000kW then the average power during the
second 15min should be 0kW to maintain an average power of 500kW.
