With the strengthening of interconnected power grid connection, interval oscillation mode damping continue to improve, interval power oscillation accidents still occur, however, the negative damping mechanism of the classic cannot be satisfactorily explain these phenomena, this paper provides the researches forced oscillation mechanism of the low frequency oscillation, the speed control system is likely to form the forced oscillation source, speed regulation system and low frequency oscillation formed an adverse coupling effect. In this paper, based on the mechanism of their method, speed control system are analyzed, the effect of various parameters on the low frequency oscillation in order to avoid speed regulation system to participate in the low frequency oscillation provides technical support.

This paper proposed a new method to locate the source of forced oscillation that involves resonance with natural oscillation modes. The new method is based on comparing the oscillation mode shape of the forced oscillation with that of the natural oscillation that the forced oscillation resonates with. The oscillation source is the location that has the largest angle difference between the forced oscillation mode and the natural oscillation mode. Some examples in the actual U.S. EI system verified this approach.
