Patent ID: 7345456

Claim:
A stabilizer for a synchronous electric power generator system, comprising: a processing unit; a memory, said memory storing a routine executable by said processing unit, said routine: receiving a voltage signal indicative of a voltage output by said synchronous electric power generator system and a current signal indicative of a current output by said synchronous electric power generator system; generating a power system stabilizer signal utilizing said voltage signal and said current signal for damping oscillations in said synchronous electric power generator system; generating an excitation limiter function signal utilizing said voltage signal and said current signal for controlling an excitation level of said synchronous electric power generator system; generating a feedback signal for said synchronous electric power generator system by combining said power system stabilizer signal and said excitation limiter function signal; and said excitation limiter function signal comprising a minimum excitation limiter function signal, an under excitation limiter function signal, a volts per hertz function signal, a generator current limiter function signal, and an over excitation limiter function signal.
