Individual results for certain object types (every single hour)

If individual results are requested, it is possible to retrieve them as line charts after a calculation. The result is only saved until the next load calculation is performed since the volume in the result table tends to get very large very fast.

The graphic is displayed by using the right-click menu on a calculated object.

Cable

Calculated values > Hour values > Result graphic

For the cable it is possible to request result, load current and/or relative load current.

Example of a conductor current displayed in a chart.

Node (bus bar, joint, delivery point etc.)

Transformer

Show hourly value results in map / schema

If results are saved for each hour, it is also possible to use a variant of the usual result presentation in a map / schedule to color the grid depending on the calculation result. You must then use a presentation template that contains one of the result terms in (H) in the start form.

Right-click on a calculation result and select Show hourly value result in map.

The network is now colored according to the presentation template, and a window with an explanation opens.

Via the slider under the legend, it is possible to set the hour for which the result is to be presented.

You can also view results in charts for selected objects from here by using the chart icon.

Results report

There is a special report for load profile calculations if you have selected to perform a complete calculation at the same time as the prognosis.

The report presents all the maximum current/maximum relative current for the conductors and the lowest voltage and time for the nodes during the requested calculation interval.

Retrieve all load profiles for one meter

Right-click on an object that has stored load profiles.

Select Calculated values > Hour values > Result graphic

All the curves from one day that are stored will be displayed. Only the active curve including the spread.

Display the curve that was used as input for the last prognosis/calculation

The prerequisite is that the input curves are saved in the database. Only the input data for the latest calculation is saved.

The input data curves are retrieved interactively through the interface.

If you right-click on an object that has a stored load profile and was a part of the latest calculation, the alternative Input to calculation graphics is available:

Calculated values > Hour values > Input to calculation graphic

Extreme values

Thanks to the function of displaying extreme values in the map / table, the results of value calculations, for each object it is possible to display: the highest load, the lowest voltage, etc. in the calculated period of time.

Functions are added in the drop-down menu (right-click) on a load profile calculation.
