Zone Maintenance Factor

Units:	-
Mode:	Input/Output
Multi-band:	False
Default Value:	1
Validation Rule:	≥0
Key Property:	No
Description:	Maintenance factor
Detail:

Zone Maintenance Factor is the maintenance profiling factor used by PASA to 'shape' maintenance events into appropriate periods of high capacity reserves. The factor indicates the relative desirability of maintenance in any period with zero meaning 'undesirable', one being 'neutral', and values above one meaning 'desirable'. The PASA setting Maintenance Sculpting can be used to shape the maintenance events more aggressively into the high reserve periods.

Input

When used as an input you must ensure that the sum of Maintenance Factor across hours of a year sums precisely to the number of hours in the year, so that the average factor is unity; as in the following example of patterned input data. In this case no maintenance will occur in months January and December.

NOTE: If your planning horizon is less than a year the factors need not average unity.
