电流型交－交变频同步电机电路的等效绕组分析法

Equivalent Circuit Analysis for Synchronous Motors

对电流型交－交变频同步电机电路作等效变换，用等效绕组求出电机稳态时电流和转矩的解析式。该解析式可反映出电机的换流重迭角、提前换流角、功角及换流剩余角对系统性能的影响。利用该解析式所产生的模拟结果与仿真结果基本一致。

An equivalent circuit analysis for synchronous motors with AC-AC current source converters is carried out. An analytical formula for current and torque at steady state is presented, which can reflect the influence of motor side overlap commutating angle, non-load leading commutating angle, power angle and abundant commutating angle on the operation of the motor. Derived results are consistent withsimulated results.
