| 摘 要： | 为缩短计算时间,用二维数值模型分析斜槽发电机的波形问题.建立了时域有限元模型,推导了谐波电势的斜槽系数,得出了定子斜槽时空载电压波形畸变率,提出了时域有限元计算中时间步长的选用建议.所用方法对快速准确地计算电力系统中的谐波问题有一定参考意义.

| Abstract: | To reduce calculation time,the finite element method coupled circuit in time domain was employed to calculate the no load voltage waveform.A two dimensional model in time domain was built,the skewing coefficient of back emf was deduced to consider the function of skewed slots in stator.The telephone harmonic distortion(THD) of synchronous generator was obtained.In addition,a suggestion about time interval in time domain was raised.The presented method has significance to the harmonic analysis in power system. |
