Average Values
Function Description of Average Values
Average values can be formed based on different measurands:
•
Operational measured values
•
Symmetrical components
Through the settings, you can set how and when the average values are formed. The settings describe:
•
Time slot over which the average value is formed
(Parameter: Average calc. interval )
•
Update interval for the display of the average values
(Parameter: Average update interval )
•
Synchronization time for establishing the date of commencement updating information, for example, at
the top of the hour (hh:00) or at one of the other times (hh:15, hh:30, hh:45).
(Parameter: Average synchroniz. time )
Average values are formed through the following measurands:
•
Operational measured values except for phase-related ratings
•
Amounts of the symmetrical components
You reset the average value formation via the
•
Binary input >Reset average value
•
DIGSI

NOTE
With the P, Q sign parameter in the function block General, the sign of the following measured values
of the respective function group can be inverted (see Chapter 9.2 Structure of the Function Structure of the
Function, section Inversion of Output-Related Measured and Statistical Values):
•
Active power (total): P total
•
Reactive power (total): Q total
Application and Setting Notes for Average Values
The average value formation functionality is not preconfigured with the devices in the function group. If you
use the functionality, you must load it from the library into the respective function group.
The following settings listed for the calculation of the average values can be set with DIGSI and at the device.
You find the setting parameters in DIGSI in the project tree under Settings > Device settings.
Parameter: Average calc. interval
•
Default setting: (_:104) Average calc. interval = 60 min
