6.2.3 Frequency synchronisation
During the synchronisation sequence, the controller uses frequency synchronisation regulation to match the genset frequency to the
frequency of the busbar.
More information
See Breakers, synchronisation and de-loading, Introduction, Regulation required for synchronisation for more
information.
6.2.4 Phase synchronisation
For static synchronisation, during the synchronisation sequence, the controller uses phase synchronisation regulation to match the
genset phases to the phases of the busbar.
More information
See Breakers, synchronisation and de-loading, Introduction, Regulation required for synchronisation for more
information.
6.2.5 Power regulation
When there is a genset (or emergency genset in harbour mode) connected to the busbar along with other gensets, and/or shaft
generator, and/or shore connection, then the controller can use power regulation (that is, active power).
The controller also uses power regulation when ramping up the power to a genset (increasing the load), or ramping down the power
of a genset (decreasing the load).
If multiple gensets are connected to the same busbar section, a GENSET controller can regulate the power from its genset.
Connected gensets automatically run at the same engine speed. Therefore, decreasing the fuel to one genset automatically
increases the active power from the other genset.
More information
See Breakers, synchronisation and de-loading, Introduction, Regulation required for de-loading for more
information.
INFO
If a single genset is connected to the busbar, changing the governor input only changes the frequency of the genset and
not the power.
Alternatively the power set point can be configured using Modbus.
More information
See Regulation, External communication using Modbus for more information about how the power set point is
configured using Modbus.
Analogue governor output power parameters
The following table contains the parameters for an analogue governor output that are used during power regulation.
The power regulation parameters define analogue regulation when the controller regulates the governor to change the genset active
power output.
Configure these parameters under Configure > Parameters > Regulators > GOV analogue configuration > Power regulation.
Parameter
Range Default Notes
Kp 0 to 60 0.5 The PID gain for the regulator.
Ti 0 s to 1 min 5 s
The PID control integral time.
