双馈电机运行速度对稳态性能的影响

Speed Effect on Steady Performance of Doubly fed Motor

研究双馈电机运行速度对双馈电机稳态性能的影响。首先对比了双馈电机运行于超同步转速及次同步转速时的稳态波形,然后对谐波及稳态参数的变化进行了分析。研究表明双馈电机稳态运行速度对其稳态运行性能有较大影响。

This paper aims at the effect of speed on the doubly - fed motor. We first compare the steady waveforms of the motor operating at super - ynchronous speed with that of the motor operating at sub -synchronous speed,and then analyze the harmonic frequency and the variation of steady performance parameters. The study reveals that the speed has much effect on the doubly - fed motor.
