Functions
◦ Genset(s) drive the ship's shaft
◦ Another shaft generator drives the ship's shaft
• Power requirement to drive the ship's shaft treated as a load
• Propeller zero pitch digital input
• Shaft generator fixed speed digital input
Counters
• Display unit counters, to edit or reset
◦
Running hours (total, and trip)
◦ Shaft generator breaker operations and trips
◦ Energy export (active and reactive) (to the busbar)
◦ Energy import (active and reactive) (to the shaft generator)
◦ External breaker operations
• Energy counters with configurable digital outputs (for external counters)
◦
Energy export (active and reactive) (to the busbar)
◦ Energy import (active and reactive) (to the shaft generator)
Control types
• Power management system (PMS) control
◦
Display unit push-buttons for breaker operations
◦ Synchronisation, de-loading, and breaker control
◦ Push-button functions also possible using inputs, PICUS, and/or Modbus
• Switchboard control
◦
Operator controls the system from the switchboard
◦ Only the controller protections are active
Regulation
• Regulators for relay outputs and analogue outputs
◦
Regulation delay
• Governor regulation
◦
Fixed power
◦ Active power load sharing
◦ Active power ramp down
◦ Frequency-dependent power droop
• AVR regulation
◦
Fixed cos phi
◦ Fixed reactive power
◦ Reactive power load sharing
◦ Voltage droop
• Configurable: Power ramp up, power ramp down
10.2 SHAFT generator controller principles
10.2.1 Adding a SHAFT generator controller to the single-line diagram
Configure each SHAFT generator controller in the single-line diagram, using PICUS.
To add a SHAFT generator controller to the single-line diagram:
1. In PICUS, under
Configure > Single-line , drag the shaft generator icon to the right place on the
single-line diagram.
2. Select the SHAFT generator controller on the single-line diagram, and make sure that its Controller ID
is correct.
3. Broadcast the changes to all the controllers in the system.
• If needed you can override the controller ready status.
