SLAC synchronous condenser [PDF]

Proceedings Particle Accelerator Conference, 2002
A synchronous condenser is a synchronous machine that generates reactive power that leads real power by 90 degrees in phase. The leading reactive power generated by the condenser offsets or cancels the normal lagging reactive power consumed by inductive and nonlinear loads at the accelerator complex. The quality of SLAC's utility power is improved with

Dynamic Behaviors and Protection Strategy of Synchronous Condenser Integrated Power System Under Non-Full Phase Fault Conditions

IEEE Access, 2019
When a synchronous condenser connected power network encounters a non-full phase fault, the amplitude of the stator current is severely suppressed by the magnetic field generated inside the synchronous condenser, in which the sensitivity of failure ...
