摘　　要：分析了三种求取饱和直轴同步电抗的方法,其中一种是对的,两种是错的。并指出饱和直轴同步电抗是一个虚拟量,求取该量必须对空载特性虚拟化即线性化。This paper analyzes three methods of finding the saturated direct-axic synchronous reactance,one of which is right and two of which are wrong.It is pointed that the saturated direct-axis synchronous reactance is a virtual quantity and it have to be solved by virtualization(linearization)of no-load characteristics.

关 键 词：凸极同步发电机 饱和直轴同步电抗 空载特性 短路特性 零功率因数特性
