Substation Equipment: Synchronous Condensers

Synchronous Condensers
A synchronous condenser is a synchronous machine running without mechanical load and supplying or absorbing reactive power to or from a power system. Also called a synchronous capacitor, synchronous compensator or rotating machinery.

In November 1995, the first static synchronous compensator began operating at a TVA substation in Knoxville, Tennessee. This compensator can regulate voltage without expensive external capacitors or reactors.
