Controlling
Parameter: Check switching authority
•
Default setting (_:107) Check switching authority = yes
With the Check switching authority parameter, you specify whether the switching authority (On-site,
Remote) is checked during an adjusting command.
Parameter: Control model
•
Default setting (_:109) Control model = SBO w. enh. security
This parameter Control model specifies the control model according to IEC 61850-7-2 that corresponds to
the behavior of the data (SBO – Select Before Operate).
You can select one of the following settings:
•
direct w. normal secur.
•
SBO w. normal secur.
•
direct w. enh. security
•
SBO w. enh. security
Parameter: SBO time-out
•
Default setting (_:110) SBO time-out = 30.00 s
This parameter specifies the time for detecting the time-out of the SBO command. The range of values
extends from 0.01 s to 1800.00 s. This is the time that can elapse between command acceptance and
command execution (command model as per IEC 61850-7-2).
Parameter: Feedback monitoring time
•
Default setting (_:111) Feedback monitoring time = 10.00 s
Reaching a new tap position after the adjusting command is monitored via the feedback-monitoring time. If a
new tap position is not reached, the command is canceled after this time.
Parameter: Set point mode active
•
Default setting (_:14011:160) Set point mode active = on
With the Set point mode active = on parameter, you can send a target voltage to the controller via a
communication network. The controller uses the specified voltage value as target voltage. If the controller
does not receive any valid voltage values, it uses the original target voltage. You can enable or disable the
parameter.
For the three-winding transformer, the address of the parameter Set point mode active is
_:15601:171, for the grid coupling transformer, it is _:16351:171.
Two-Winding Transformer only:
Parameter: Number of target voltage
•
Default setting (_:14011:156) Number of target voltage = 1
With this parameter, you specify the number of available target voltages (1 to 4). You can select a target
voltage from the available ones using the function key, communication, or binary input.
NOTE
Keep in mind that the parameter Number of target voltage cannot be influenced by way of the
settings group switching.
You can specify the target voltages (1 to 4) in primary, secondary, or in percent.
For the activation of the target voltage 1 to 4 via a binary input, you need a CFC chart.
Parameter: Target voltage 1
•
Default setting (_:14011:112) Target voltage 1 = 110.000 V
With the Target voltage 1 parameter, you specify the voltage that the controller is supposed to reach.
Parameter: Target voltage 2
