TerminologyTerminology
Weighting Procedure : Internal System procedures that are applied to existing meter
reading results ,period consumption/demand values for determining expected
values for extrapolation/proration.
Weighing Key : User Defined weighting keys are allocated to predefined weighting
procedures. Used in Operands and Register Groups
Weighing Unit : Is ia fixed Value. The periods for the distribution of weighting units
are always indicated by the month or day and is year independentEx. Weighting Unit for the month of Jan = 200
Weighting Units for the whole Year = 1000Weighting Units for the whole Year = 1000
Weighting Portion (%)for the month of Jan = (Weighting Porting of Jan/ Weighting Units for whole Year)*100
= (200/1000)*100 = 20%
Period Length of Portion : defines the interval for billing the associated contracts.
Defined in Portion
Minimum portion in Percent : This is multiplied by the period length to determine
the period for which the meter reading results should be available for the system to
extrapolate based on existing meter reading results.
Base Period Category : This is present in the Installation.
This helps to control whether to extrapolate the expected values based on the
previous period or the previous year.
�For determining whether a Period is representative :
Minimum portion in percent * Length of meter reading period
= Minimum length of base period
Or
Weighing Portion of Period = Minimum Portion
Lets say the Minimum Portion is 30%
Determination whether a Period is RepresentativeDetermination whether a Period is Representative
Lets say the Minimum Portion is 30%
The Period length for Meter Reading is 365 days.
So the Minimum length of base period = 30% of 365 = 109.5 days
So if the period between the two MR is less than 109.5 days then the Period is
not representative. If the weighing portion for the period between the two MR
is less than the Minimum Portion then also the period is not representative.
When the period is not representative ,extrapolation is based on the periodic
consumption rather than on Meter Reading results.
Here I shall only be discussing the scenario of “Forecast from pervious periods
with minimum portion”
