Need VARs?

Increase VARs with a generator to synchronous condenser conversion

Solutions to customer concerns can comprise the static VAR (volt-amperes reactive) compensators, shunt capacitor banks, and/or synchronous condensers. Each of these options is beneficial to grid stability and reliability. However, dynamic VARs generated from a synchronous condenser conversion are widely considered to be a preferred approach as they produce a superior response to grid voltage fluctuations while providing a cost-effective solution to the owner.

GE now offers solutions that convert existing synchronous generators, powered by steam or gas turbines, into synchronous condensers with reduced disruption to the existing plant. Since each plant’s high voltage electrical system is unique, GE’s solution is custom engineered using our extensive electrical system experience. GE’s solution is focused on clean-waveform static start technology to drive the generator to synchronous speed.

Synchronous condenser conversion features

  • Static start capability–VFD technology
  • Motor start capability–VFD technology
  • Turbine start capability–using clutch
  • Mark* VIe controller–integration with plant controls
  • Start button to sync in approximately 20 minutes
  • Automated synchronization control

Synchronous condenser conversion benefits

  • Increased return on original plant investment
  • Reduced cost – reuse of existing generator and auxiliaries
  • Operational mode flexibility
  • Substantial VAR capacity
  • Superior response to power system fluctuations
  • Excellent short circuit support
