【摘要】 为了研究定子附加绕组型励磁同步发电机的运行行为,本文中建立了同步发电机/励磁变压器/三相半控桥/负载的数学模型。模型中,将电机看作一个非线性时变电路网络而得到同步发电机的数学模型;并与励磁变压器、负载方程相联立;由三相半控桥各导通模式下的基本方程对应地得到整个系统的四种形式方程,六个通断判据将四种形式方程联系起来。在此数学模型基础上的仿真结果与72-D₂同步发电机的实验结果相对照,吻合较好。更多还原

【Abstract】 In order to research the operation behaviour of the synchronous generator with sta-tor additional winding excitation, the mathematical model of the generator/excitation transformer/three phase half-controlled rectifier/load is developed. In this model, the equation of the generator is obtained by considering it as a nonlinear time-varying circuit network. The overall system model has four basic forms corresponding to the five conduction modes of the rectifier respectively, The four forms are integerated as a whole by six conduction/turn-off criteria of the rectifier. The simulation results with this model are very close to the experimental results on the rewound generator 72-D2.更多还原
