摘　　要：异步化同步发电机可以较好地解决电力系统的无功过剩和稳定问题。为了进一步改善异步化汽轮发电机的动态和暂态性能 ,采用一种新的控制方法 :在动态同步轴系下建立异步化汽轮发电机的励磁控制方程。并同时仿真研究了异步化汽轮发电机在同步轴系和动态同步轴系的控制效果。研究表明 ,异步化汽轮发电机在动态同步轴系下的动、暂态性能比在同步轴系下有明显的改善。因此 ,相对于同步轴系而言 。Asynchronized Generator can better solve the excessive reactive and stability problem in power system.In order to improve the dynamic and transient performances of an asynchronized turbogenerator(ASTG),excitation control equation of it in the dynamic synchronous reference frame is presented.Control results are simulated in the synchronous and dynamic synchronous reference frames for ASTG.It is shown that the dynamic and transient performances in the dynamic synchronous reference frame are better than those in the synchronous reference frame.Consequently,the control strategy of dynamic synchronous reference frame can shorten more time on the dynamic process of ASTG.
