5.5.4.3 SETPOINTS
Setpoint > Control Elements > Synchrocheck
There is only one synchrocheck unit in the F650.
Table 5–72: 25 UNIT SETPOINTS
setpoints description for 25 unit:
Function permission (Function): This setpoint allows enabling and disabling the synchrocheck unit.
Voltage Level determination setpoints for busbar and line:
This setpoint group allows determining the voltage levels considered as dead and live for line and busbar voltage.
Dead Bus voltage level (Dead Bus Level): Voltage level considered as dead bus
Live Bus voltage level (Live Bus Level): Voltage level considered as live bus
Dead Line voltage level (Dead Line Level): Voltage level considered as dead line
Live Line voltage level (Live Line Level): Voltage level considered as live line
Synchrocheck setpoints (live bus, live line):
F650 relays verify synchronism by establishing and comparing three basic parameters: the difference in
module and angle of voltage phasors, and the frequency slip of a phasor related to the other one.
synchrocheck setpoints include a fourth time setpoint, that allows using an anticipative algorithm to issue a
closing signal.
Voltage Difference (Max Volt Difference): Maximum Difference in module between the line and busbar voltage
to allow a closing in the synchrocheck unit.
Angle Difference (Max Angle Difference): Maximum Difference in angle between the line and busbar voltage
to allow a closing in the synchrocheck unit.
Frequency Slip (Max Freq Difference): Maximum difference in frequency (slip) between both voltage values to
be compared in the synchrocheck unit.
Breaker Closing time (Time): Estimated breaker Closing time, used for establishing the Closing order in a
moment that allows the busbar and line voltages to be in phase.
