A new nonlinear excitation controller for generators

In order to overcome the shortcomings of conventional excitation controller, this paper introduces the theory of direct linearization over wide range (a nonlinear system control theory) to the power system to design excitation controller for generators. The theory surmounts the difficulties in controller design caused by the strong nonlinearity of power systems and makes the linearization process more straightforward than the well-known differential geometric method.Based on this, the concept and theory of dynamic compensation via feadback are presented so that the controllers designed are of better robustness against the changeability of the operating point and configuration of the power systems. Finally, computer simulation and experiments in scaled power system are conducted with challenging results.
