Abstract :
The power system forced power oscillation will be excited by the continuous cyclical small power disturbances. The forced power oscillation theory can explain some low frequency oscillations that are not caused by negative damping. In this paper, the multi-machine power system forced power oscillation is analysed on the dominant oscillation mode based on EEAC theory. And then the condition on which the amplitude of forced power oscillation caused by two disturbance sources can be the maximum is studied. A method of prime mover disturbance source identification is presented and verified.
