| 摘 要： | 在N机电力系统的原始动力学模型基础上得出一个新的励磁控制设计的数学模型，它克服了以往设计模型的不足之处，体现了发电机的双轴动态特性。仅包含代数运算可分散实现的非线性反馈补偿规律保证了控制器本身的稳定性，真实完整地反映了各机组间的相互耦合作用，从而使模型适用于大型组合电力系统中励磁控制设计的需要。

| Abstract: | Based on the original dynamics of N machine power system, a new mathematical model is proposed for excitation control design in large scale power system. The new model gains many advantageous features over prevenient ones: A third order double axis dynamic model is used to represent each generator. Its nonlinear feedback compensation law, implemented just by simple algebraic calculating, guarantees stability of controller itself. Intact connections between interactive machines is reserved so that the model is suitable for excitation control design in connective multi machine power system. |
