Synchronizing equipment

Current surges caused by paralleling a generator in non-synchronized conditions can have destructive effects on power plant generators and substations: from a plant halt to severe mechanical generator damage caused by extreme electromagnetic forces.

To prevent any disruption and to reach the highest levels of safety, productivity, and availability, a reliable synchronization solution is what is needed.

Keep your assets synchronized, safe and productive with SYNCHROTACT

For more than 50 years, ABB has protected power plant generators and substations from the potentially destructive effects of current surges caused by paralleling in non-synchronized conditions with its SYNCHROTACT series of synchronizing equipment.

SYNCHROTACT has reached the 6th generation and continues to strengthen a wide portfolio of excitation products, automation, electrical and digital applications for the power generation industry across segments.

With over 22,000 installations around the world, hundreds of power generation plants, substations and motors have been kept safe and at the highest levels of availability.

FAQ


Where does SYNCHROTACT apply?

SYCNHROTACT synchronization devices are designed for

Power plants and industrial plants with own power generation

  • Hydro turbines, gas turbines, steam turbines, diesel generator sizes up to 2 GW
  • Monitoring (Synchrocheck) of automatic or manual synchronization
  • Paralleling of voltage-free lines and buses (“dead bus”)
  • Proven and reliable components
  • Maximum safety of assets by means of the SYNCHROTACT diverse dual channel concept
  • Diverse Dual Channel System - diversity of the two channels in terms of different hardware and different software
  • High availability - lean platform and fast response time for support
  • 7 parameter sets to synchronize different CBs with individual conditions
  • Remote control, using different protocols, such as IEC 61850, Modbus, Profibus


Substations for automatic paralleling of synchronous and asynchronous lines and busbars
  • Automatic paralleling of 2 lines, or busbar with line
  • Monitoring (Synchrocheck) of automatic or manual synchronization
  • Paralleling of voltage-free lines and buses (“dead bus”)
  • 7 parameter sets to synchronize different CBs with individual conditions
  • Remote control, using different protocols, such as IEC 61850, Modbus, Profibus
  • Rugged design according to IEC60255 – series and ANSI/IEEE C37.90

 Large synchronous motors 

  • Synchronizing of large AC-motors soft-started and runned up to nominal speed by means of a drive
