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.
