摘要
文章对无阻尼绕组双轴励磁同步发电机的静态稳定性进行了详细地分析,建立了其基本方程以及微干扰分析的线性化数学模型。并通过实例,根据计算机结果,对单轴励磁和双轴励磁两种发电机的稳定性进行了比较,从而说明在一定条件下,双轴励磁可以提高同步发电机的静态稳定性.
This paper analyses in detail the dynamic stability of thedual-excited synchronous generators with non-damping windings,and sets up theundamental equations and the linearized mathematical model for small distur-
bance analysis.By an example with computer results,the paper also compareshe difference of the dynamic stabilities between the single-and dual-excited synchronous machines,which explains that the dual-excited synchronous gene-
rators can increase the dynamic stability of machines under certain conditions.
