摘要
通过复模态分析,得出了当发电机采用经典模型并考虑阻尼作用时,多机系统机电振荡模式实部的解析表达式。当考虑发电机励磁控制作用时,励磁控制的影响用等值阻尼系数来表示,从而能够对多机系统机电模式特征根作出快速估算。一个10机系统的算例证明了本文方法的有效性。
The analytical expression of the real part of electro-mechanical eigenvalue is derivedfrom complex mode analysis when the generator is represented by classical model and the damping isconsidered. The effect of excitation control can be represented with equal damping and thus a fast estimation method for electro-mechanical eigenvalue is given. The 10-machine New England power systemis employed in order to demonstrate the effectiveness of the method presented in the paper.
