A stabilizer and synchronous electric power generator system using same
that provides both power system damping and excitation limiter
functionality. The stabilizer includes a processing unit and a memory
storing routines executable by the processing unit. The routines are
adapted to receive a voltage signal indicative of a voltage and a current
signal indicative of a current output by the generator system, generate,
utilizing the voltage and current signals, a power system stabilizer
signal for damping oscillations and one or more excitation limiter
function signals for controlling excitation level. The routines are also
adapted to generate a feedback signal for the generator system by
combining the power system stabilizer signal and one or more of the one
or more excitation limiter function signals.
