异步牵引电动机在低频段的间接转矩控制

Indirect torque control of asynchronoust raction motor in low frequency range

针对牵引应用中要求机车启动转矩大、转矩脉动小的特点,提出了异步牵引电动机在低频段的转矩控制方案及其仿真模型,阐述了基本原理,给出了数学关系和仿真结果。仿真结果表明,该方案可行。

The torque control scheme and simulation model of the asynchronous traction motor inlow frequency range is proposed in the light of the requirement of traction applications, like highstarting torque and low torque ripple of locomotives. Basic principles are explained, and mathematicalrelationships as well as simulation results are presented. Simulation results prove the feasibility ofthe scheme.
