同步发电机非线性广义子系统模型的解耦控制

Decoulping Control of a Turbo Generator Based on the Nonlinear Singular Sub-System Model

针对基于非线性奇异子系统模型的同步发电机,本文利用逆系统方法,研究了其励磁汽门综合控制的输入输出线性化解耦问题。同步发电机本质上是电力大系统中的一个非线性奇异子系统,同步发电机的解耦控制是使系统达到优良性能的重要途径之一。本文提出一种递推算法,利用逆系统方法将被控系统转化为两个独立的积分型线性子系统,实现了系统的动态解耦。仿真结果表明了本文所提控制方法的有效性。

This paper discusses the decoupling control of the turbo generator.The turbo generator is essentially a nonlinear singular subsystem of the power system.The controlled turbo generator can be transformed into two independent sub-systems based on the inverse system method with a recursive algorithm proposed in the paper.Simulation results are also given.
