  • Stand-by emergency genset accomplishes power supply to essential load during power drop.
  • Controller automatically starts the genset in case of mains failure and switches load to generator. When mains returns, it synchronizes the generator back, softly unloads it and stops the engine.
  • Generator automatically synchronizes to mains in Test mode. Test mode can be used to check the genset condition and to provide uninterrupted power supply in case of expected mains failure.
  • Status of the genset is displayed in the distribution point.
  • Service contractor connected via Internet and InteliSupervisor PC software has complete information on status and performance of gensets. Each important alarm immediately pops-up on PC screen.
  • InteliSupervisor is used for supervision of complete fleet of gensets located on many sites.
  • History file with performance log stored in IG-EE allows easy backtracking and problem solving.
  • Seamless communication with engine’s electronic injection control unit, all important values and alarms are visible on screen of InteliGen and stored to the history file in plain language.

  • Fully automatic system reduces electric energy bill by keeping the mains power bellow high tariff level during peak hours.
  • At the same time it accomplishes emergency standby power in case of mains failure.
  • Remote control and monitoring uses available factory LAN for connection between a Power house and a Control room.
  • Service contractor connected via Internet and InteliSupervisor PC software has complete information on status and performance of gensets. Each important alarm immediately pops-up on PC screen.
  • InteliSupervisor is used for supervision of complete fleet of gensets located on many sites.
  • Wide range of engine and generator protections, including vector-shift protection.
  • Automatic forward and reverse synchronisation with soft load ramp-up and ramp-down during changeover.
  • Active and reactive load Import/export control and load-sharing.
  • Automatic optimization of number of running sets according to loadPeak loping controlled by built in Scheduler, engines automatically run during peak period.
  • Automatic equalization of running hours of particular engines
  • History file with performance log stored in IG-NT allows easy backtracking and problem solving.

  • Automatic optimization of number of running sets according to loadPeak loping controlled by built in Scheduler, engines automatically run during peak period.
  • Essential load is fed by two mains feeders during normal operation to accomplish maximum reliability of the power delivery. Bus-tie breaker (BTB) is closed.
  • Complex switching algorithm running in external PLC defines which breakers are opened and with are closed in dependence on availability of two mains and gensets.
  • Reverse synchronizing on both feeders and on bus-tie breaker is accomplished by 3 InteliMainsNT modules controlled by external PLC.
  • Active and reactive load-sharing can operate in two modes:
    • - Sharing the load between all running gensets – if BTB is closed
    • - Sharing the load in two independent groups – if BTB is opened
  • Automatic power dependant start/stop can operate in two modes as well:
    • - Running on all gensets – if BTB is closed
    • - Running in two independent groups – if BTB is opened
  • All controllers are interconnected by one CAN bus all the time, disregarded if BTB is closed or open, no need for relays reconnecting the CAN bus.
  • Complete system is remotely controlled and supervised from Control room connected via company LAN and IG-IB to all controllers.
