Abstract
A scheme for stabilizing a synchronous alternating current generator through the excitation control to dampen generator oscillations includes a power system stabilizer responsive to signals representing the generator output voltage and output current to provide an oscillation signal which represents the instantaneous magnitude of the generator oscillations. A modulator means is included which develops a signal, representing the generator voltage with respect to neutral, and this latter signal is multiplied by the oscillation signal to provide a control signal which controls the excitation of the generator.
