10.2.2 Nominal settings
Generator nominal settings
These nominal settings are under Configure > Parameters > Generator > Nominal settings > Nominal settings #, where # is 1
to 4.
Table 10.1
Controller nominal settings
Nominal setting Range Default Notes
Voltage (V) 10 V to 160 kV 400 V The phase-to-phase nominal voltage for the shaft generator.
Current (I) 1 A to 9 kA 867 A
The maximum current flow in one phase (that is, L1, L2 or L3) from the shaft
generator during normal operation.
Frequency (f) 48 to 62 Hz 50 Hz
The system nominal frequency, typically either 50 Hz or 60 Hz. All the
controllers in the system should have the same nominal frequency.
Power (P) 1 kW to 900 MW 480 kW The nominal active power may be on the shaft generator nameplate.
Apparent power (S) 1 kVA to 1 GVA 530 kVA The nominal apparent power should be on the shaft generator nameplate.
Power factor (PF) 0.6 to 1 0.9 The power factor should be on the shaft generator nameplate.
The controller uses the nominal settings to calculate the nominal reactive power (nominal Q) for the shaft generator. The controller
can be configured to calculate the nominal active power (nominal P) or the nominal apparent power (nominal S). In this case, the
controller uses the calculated values, and ignores any entered values.

See AC configuration and nominal settings, Nominal settings, Nominal power calculations for more information.
Busbar nominal settings
These nominal settings are under Configure > Parameters > Busbar > Nominal settings > Nominal settings #, where # is 1 to 4.
Table 10.2
Controller nominal settings
Nominal setting Range Default Notes
Voltage (V) 10 V to 160 kV 400 V
The phase-to-phase nominal voltage for the busbar. If there is no transformer
between the shaft generator and the busbar, the nominal voltage for the busbar will be
the same as the nominal voltage for the shaft generator.
Frequency (f) 48 to 62 Hz 50 Hz
The system nominal frequency, typically either 50 Hz or 60 Hz. This should be the
same as the shaft generator nominal frequency, and all the controllers in the system
should have the same nominal frequency.
10.2.3 Power management
The SHAFT generator controller works together with the other controllers in the system to provide efficient power management.
More information
See Power management for more information.
10.2.4 Running detection
The controller can be configured to receive engine running feedback from a variety of measurements.
The SHAFT generator controller uses running detection for:
• The controller status texts (in the display unit and PICUS)
• The Engine running and the Engine not running inhibits
