摘要
分别建立六相电压型逆变器和六相双丫移30°绕组同步电动机的动态仿真数学模型.为了便于考虑变频器和电动机之间的接口,以及深入分析转子阻尼绕组对系统动态性能的影响,定子采用基于线电压的静止a—b—c模型,转子采用多回路模型,并对电动机的空载软起动过程进行了仿真和分析。数字仿真的结果表明,六相双丫移30°绕组同步电动机转矩脉动小,有利于系统的稳定运行,在电力推进等领域将得到重要应用。
The dynamic simulation models of six-phase voltage source inverter and six-phase double
star windings shifted by 30°synchronous motor are set up respectively. The resting a-b-c stator model
based on the line voltage and the multi-loop rotor model are adopted in order to deal with the inter-
face of the transducer and the motor expediently and to analyze the effect of the damper winding on
the dynamic performance of the system deeply. The no-load soft-starting process of the motor is simu-
lated and analyzed. The digital simulation results show that this motor with small rippling torque is
very suitable for the steady operation of the system, and will be used in the electric propulsion domain
weightily.
