Control and research on steady-state small oscillation of rare-earth permanent magnet generator

When rare-earth permanent generators operate, it might occur oscillation phenomena because of the influence of unfavorable factors. Generator oscillation is extremely adverse for itself and power system. Seriously, users can´t work normally, electrical and equipment damage. Generator oscillation problem is very complex. Here, we only analyze steady-state small oscillation of synchronous generators. Controlling steady-state small oscillation based on fuzzy PID controller. Analysis of steady-state small oscillation is introduced, as well as principle and functions of fuzzy PID controller. The simulation research is carried out, fuzzy PID controller to eliminate small oscillation is better than general PID controller.
