Table 5.25 Analogue phase synchronisation parameters
Parameter Range Default Notes
Kp 0 to 60 2.5 The PID gain for the regulator.
Ti 0 s to 1 min 2.5 s
The PID control integral time.
To turn off the integral component, set Ti to 0. This might cause unexpected regulator
behaviour.
Td 0 to 2 s 0 s The PID control derivative.
INFO
The phase synchronisation parameters are only used when static synchronisation is selected.
Relay regulator output parameters
Configure these parameters under Configure > Parameters > Regulators > GOV relay configuration > Frequency
synchronisation.
Table 5.26
Relay frequency synchronisation parameters
Parameter Range Default Notes
Kp 0 to 100 10 The gain for the regulator.
Configure these parameters under Configure > Parameters > Regulators > GOV relay configuration > Phase synchronisation.
Table 5.27
Relay phase synchronisation parameters
Parameter Range Default Notes
Kp 0 to 100 10 The gain for the regulator.
INFO
The phase synchronisation parameters are only used when static synchronisation is selected.
5.5 Synchronisation and breaker alarms
5.5.1 Breaker synchronisation failure
This alarm alerts the operator about a breaker synchronisation failure.
The alarm is based on the synchronisation of the source to the busbar, as measured by the
controller. The alarm is activated if the controller has not been able to synchronise within the
delay time.
Configure the parameters under Configure > Parameters > Breakers > [Breaker] monitoring > Synchronisation failure. The
alarm action is always Trip [Breaker] and Latched.
