The Design And Implement Of Nonlinear Excitation Controller

This paper works on power systems nonlinear excitation controller, the nonlinear excitation arithmetic based on differential geometry is studied theoretically, and analyze the influence of this kinds of controller to the power system, and talk about how to implement such a controller.In the analysis of nonlinear excitation exact arithmetic linearigation theory, talk about some basic formula and theory of nonlinear math, analyze the theory and practical arithmetic of the nonlinear system. This arithmetic could been used in a lot of areas.The math analysis of synchronous generator is given, this analysis is based on Park transform, and give out the state equation of a single generator infinite net system. By exact linearization arithmetic, the practical controller rule was given out. Then the paper analyzes the influence to the power net of nonlinear excitation controller.The paper gives out the pivotal technique to implement this system, include AC sampling technique, implement of control arithmetic and the implement of pulse, Fourier transform was used to implement the AC sampling, the paper introduces the implement of control arithmetic and pulse, the system realizes the relevant function.
