Damping of power system oscillations is accomplished by additionally directing exciter-voltage regulation for individual system generators in accordance with variations in the derivative of reactive power generated by a generator. Signal voltage proportional to reactive power in generator output is differentiated to develop a signal voltage representing rate of change of reactive power variations which is applicable as an auxiliary input for determining operational control of exciter-voltage regulation of the generator. Control for suppressing system oscillations is continuous as long as generator bus voltage does not exceed pre-set upper and lower voltage limits.
