Parameter: Rated voltage
•
Default setting (_:2311:104) Rated voltage = 400.00 kV
The measured values of the voltage controller can be displayed as primary values, secondary values, or in
percent. With the Rated current and Rated voltage parameters, you set the reference value for the
percentage values.
Tap Changer
The parameters of the tap changer inside the voltage controller correspond to those of the tap changer in
chapter 8.8.2 Application and Setting Notes.
For the tap changer inside the voltage controller, the parameters for the control model are copies of those
from the voltage controller. This concerns the parameters:
•
Checking the switching authority
•
Control model
•
SBO

Voltage Controller
Parameter: Mode
•
Default setting (_:14011:1) Mode = on
With the Mode parameter, you switch the voltage controller in on, off, or in test operation.
Parameter: Operating mode
•
Default setting (_:14011:101) Operating mode = Manual
With the Operating mode parameter, you specify whether the controller is operating in Auto mode or in
Manual.
Three-Winding Transformer only:
Parameter: Winding selection
•
Default setting (_:15601:157) Winding selection = Winding 1
With the Winding selection parameter, you specify whether the controller controls the voltage of
Winding 1 or Winding 2. With the WithMaxLoad parameter, the voltage to be controlled is selected auto-
matically depending on the load current. With this method, you can toggle using the parameter Winding
selection or the controllable
Automatic winding selection
.
If the controllable
Automatic winding selection
is set to Off or is not set, you can influence the
winding to be controlled using the following 2 options:
•
Using the Winding selection parameter
•
Using the
Manual winding selection
controllable
The function value
Active winding
shows the winding selection.
Only Grid Coupling Transformer:
Parameter: Winding selection
•
Default setting (_:16351:161) Winding selection = Winding 1
With the Winding selection parameter, you specify whether the controller controls the voltage of
Winding 1 or Winding 2.
You may select the winding to be controlled using the Winding selection parameter or the
Manual
winding selection
controllable. The function value
Active winding
shows the winding selection.
