5.5.4.4 SYNCHROCHECK STATES
Internal signals provided by the G650 (
Actual> Status > Control Elements > Synchrocheck
) for the synchronism
element are as follows:
Table 5–82: SYNCHROCHECK INTERNAL STATES
SYNCROCHECK BLK INP:
Block signal for the synchrocheck element, configurable at
Setpoint > Relay
Configuration > Protection Elements
SYNCROCHECK OP:
Closing permission signal in live line-live bus conditions with open breaker.
SYNCHK CLOSE PERM:
General Closing permission of the Synchronism element. It contemplates all possible
situations, live line-live bus conditions, and the closing permission logics (dead line-
dead bus, live line- dead bus, dead line-live bus).
Note
: in case the Function is
disabled, the Closing permission signal will be activated in order not to interfere with
possible logics where it is included. If the synchronism element is enabled, this signal
will only be activated in the closing conditions established by setting.
SYNCROCHECK COND OP:
Closing permission according to permission logics (DL-DB, LL-DB, DL-LB).
DL-DB OPERATION: Closing permission in dead line – dead bus condition.
DL-LB OPERATION: Closing permission in dead line – live bus condition.
LL-DB OPERATION: Closing permission in live line – dead bus condition.
SLIP CONDITION:
Internal signal indicating frequency slip between the line voltage and bus voltage
phasors.
BUS FREQ > LINE FREQ:
Busbar Frequency higher than line frequency
BUS FREQ < LINE FREQ:
Busbar Frequency lower than line frequency
VOLTAGE DIFFERENCE:
Voltage difference in Volts between line and busbar
FREQ. DIFFERENCE:
Frequency difference in Hz between line and busbar
Voltage and frequency values for the line and busbar can be obtained, both in primary and secondary values at:
Actual> Metering > Primary Values > Voltage
VBB Primary (KV)
Busbar voltage in primary values
VL Primary (KV)
Line voltage in primary values
Actual> Metering > Secondary Values > Voltage
Line Voltage (V)
Line voltage in secondary values
Bus Voltage (V)
Busbar voltage in secondary values
