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.
