Functions
◦
Genset breaker does not open if this would cause overload or a blackout
•
Fast load-reduction
•
Configurable recovery after blackout
Efficient operation
•
Intelligent load calculations
•
Advanced load-dependent start and stop calculations
•
Advanced (individually configurable) asymmetrical load sharing
•
Secured operation (power reservation)
Load control
•
Load transfer (for synchronisation, de-loading and load sharing)
•
Load-dependent start (two sets of parameters available)
◦
For example,
Normal start
and
Faster start
(low available power)
◦
Based on active or apparent power, or on percentage of nominal power
•
Load-dependent stop (two sets of parameters available)
◦
For example,
Normal stop
and
Faster stop
(high available power)
◦
Based on active or apparent power, or on percentage of nominal power
•
Power management system calculates control set points
◦
Based on system configuration, controller modes, and load sharing
◦
Frequency, power, voltage, power factor and/or var
•
External analogue inputs as control set points
Genset priority selection
•
Manual
◦
Set using the display unit 1st priority push-button, the display unit interface, or Modbus
◦
Delayed priority shift
•
Dynamic (first genset to connect has the highest priority)
•
Running hours
Heavy consumer
management
•
Up to 4 fixed and/or variable heavy consumers per controller
•
Pre-programmed heavy consumer management sequence (with configurable parameters)
•
Digital or analogue* feedback from the heavy consumer
Busbar section
management
•
Configurable power management rules for each section
•
Up to 4 externally-controlled breakers per controller**
◦
Bus tie breakers and/or shore connection breakers
•
Ring busbar
Load sharing
•
Active power (kW) load sharing (GOV)
•
Reactive power (kvar) sharing (AVR)
•
Load sharing between gensets
◦
Over the DEIF network
•
Load sharing options for each busbar section
◦
Equal load sharing (symmetrical)
◦
Asymmetric P load sharing for gensets
◦
Asymmetric Q load sharing for gensets
◦
Shaft generator base load, with asymmetric load sharing for the gensets
◦
Shore connection base load, with asymmetric load sharing for the gensets
◦
One genset base load, with asymmetric load sharing for the other gensets
*Note: For some controllers, the default hardware does not include analogue inputs. Extra hardware must be installed if analogue
feedback from the heavy consumer is required.
**Note: Up to 3 externally-controlled breakers per EMERGENCY genset controller.
