Each of the above-mentioned quantities can be displayed over time, with a sampling every 400ms.
Each chart allows to customise the ordinate axis
according to the user's display needs, by entering a
minimum coordinate, Min, and a maximum coordinate,
Max.
The abscissa axis is fixed and display a 10s interval.
POWER DIAGRAM
3
D-Vo Dashboard provides an area allowing to display the work point in the P-Q power diagram, showing the
underexcitation curve defined by the user.
The work point, marked with a green circle, has as its coordinates the values of the active power P and of the
reactive power Q, expressed as a percentage of the rated active power value specified in the System parameters
/ Generator Data tab.
