There are 10 binary signals and 6 analog signals in the data set that is transmitted
from one TR8ATCC block to the other TR8A
TCC blocks in the same parallel
group:
Table 29: Binary signals
Signal Explanation
TimerOn This signal is activated by the transformer that has started its timer and is
going to tap when the set time has expired.
automaticCTRL Activated when the transformer is set in automatic control
mutualBlock Activated when the automatic control is blocked
disc Activated when the transformer is disconnected from the busbar
receiveStat Signal used for the horizontal communication
TermIsForcedMaster Activated when the transformer is selected Master in the master-follower
parallel control mode
TermIsMaster Activated for the transformer that is master in the master-follower parallel
control mode
termReadyForMSF Activated when the transformer is ready for master-follower parallel control
mode
raiseVoltageOut Order from the master to the followers to tap up
lowerVoltageOut Order from the master to the followers to tap down
Table 30: Analog signals
Signal Explanation
voltageBusbar Measured busbar voltage for this transformer
ownLoadCurrim Measured load current imaginary part for this transformer
ownLoadCurrre Measured load current real part for this transformer
reacSec Transformer reactance in primary ohms referred to the LV side
relativePosition The transformer's actual tap position
voltage Setpoint The transformer's set voltage (
USet ) for automatic control
Manual configuration of VCTR GOOSE data set is required. Note
that both data value attributes and quality attributes have to be
mapped. The following data objects must be configured:
• BusV
•
LodAIm
• LodARe
• PosRel
• SetV
• VCTRStatus
• X2
