5BMETERING FUNCTIONS
PROTECTION, CONTROL AND METERING FUNCTIONS
minutes for direct demand integration (non rolling) and 5 minutes for rolling
demand.
The total integration interval (TII) will be equal to the product of
integrate every
by the
number of intervals to be integrated
: TII = IBI * IE
2.5.1.1.1. NON ROLLED OR DIRECT INTEGRATION
When IBI = 1. Figure 2-62 shows an example for an interval of integration of 15
minutes.
In this type of integration the request is the average of the instant values of the
programmed parameter along the interval of integration (IBI).
Figure 2-62 Direct integration
2.5.1.1.2. ROLLED INTEGRATION
In this case IBI > 1 and the demand is calculated for each programmed parameter,
averaging the last interval to be integrated (IBI)
In Figure 2-63 an example is shown for integration every 5 minutes (IE) and three
intervals to be integrated (IBI). Load has a profile as shown by a curve, while the
demand (average) is shown as straight lines for every 5 minutes interval. The
rolling demand calculated for three 5 minute intervals will be as follows:
Demand at point 1 (IOI1) = (0 kW + 0 kW + 100 kW)/3 = 33.3 kW
Demand at point 2 (IOI2) = (0 kW + 1000 kW + 100 kW)/3 = 66.6 kW
Demand at point 3 (IOI3) = (100 kW + 100 kW + 100 kW)/3 = 100 kW
