In this section loads are defined for calculations.
Press the arrow icon for More fields to select where the loads for the calculation should be retrieved from. The options change depending on the Type selected.
Select a function for re-calculation energy to power.
To select the function Load profiles, you need access to the module Load profiles.
To select the function Historical measurement, you need access to the module Historical measurement.
This means, that manually added loads at the delivery points will be included in the calculation.
Prioritize |
Only use planned load. |
Add |
The loads are being added to the loads retrieved elsewhere. |
Exclude |
The loads are being excluded to the loads retrieved elsewhere. |
The preselected values for load levels are retrieved from the selected set of parameters.
All the power load levels are multiplied with the entered percentage number. Note that power load level also affects the power for the hour values when you perform calculations with load profiles or historical hour values. A normal load is stated with 100 %.
All the energy load levels are multiplied with the entered percentage number. A normal load is stated with 100%.
A search for loads in every delivery point is done against the loads that comes from the billing system.
If Customer facilities is not selected, no standard loads will be included in the calculation. |
Include the loads, defined in the selected reference calculation, from the network below the traced voltage level.
This function is partially replacing Saved loads as an alternative for loads when a calculation for a medium voltage network without an underlying low voltage network is done.
The function is specifically suitable for calculations with load values when you wish to perform a calculation for medium voltage. The user can include all the loads in a calculation for 10kV without running any of the low voltage.
Example:
•Trace a network for calculation on voltage level 10 kV without underlying low voltage.
•Make sure that the search for loads only includes customer data/meter data.
•Activate Aggregate loads.
•Continue with the calculation as usual.
All customer loads from the underlying network will be searched and moved to every substations upside.
It is only the loads that are moved. No generator production or project loads on 0.4 kV is included.
If both Load from reference calculation and Aggregate load are marked, Load from reference calculation will be searched first. If no Load from reference calculation is found for a station, an aggregation of loads will be performed for that station.
If this has been done, a printout is obtained in the Network Calculation Log for station/stations that does not have a Load from reference calculation.
Select the check box Include negative annual energy values from customer system to include the negative annual energy from customer system in the calculation.
Select Power to prioritize power loads. If both power and energy are stated, select Energy.
If there are monthly values saved (components on the meter in customer facility) they will be presented in a list. Year/Month can be selected for power loads. For a customer facility having power loads stored in this manner the calculation will use that value. If no such value is found, the customer facility will instead use the normal meter reading value.
