High-power synchronous motor drives are usually fed from naturally commutated cycloconverters.The output voltage of the cycloconverter contains interharmonics/subharmonics which affect the power quality and restrict the allowable frequency range.Further,a practical circulating current-free cycloconverter usually gives rise to stator current discontinuities.The present paper deals with a simulation method to study the performance of a cycloconverter-fed synchronous motor drive in the presence of interharmonics/subharmonics taking into account the discontinuities in the output current as well as the effect of ripple in the output current on the input current of the cycloconverter.Interharmonics in output phase voltage,output phase current,input supply current,and the field current are estimated and verified with experimental results on a laboratory prototype.The significant oscillating torque components due to these interharmonics are identified in a typical case.The simulation results are useful in power quality studies for such drives and in devising methods for suppression of these interharmonics/subharmonics.

大功率同步电机的驱动器通常是自然换流的交交变频器.交交变频器的输出电压包含间谐波/次谐波,这些谐波会影响电能质量并限制允许的频率范围.此外,无环流的交交变频器通常会引起定子电流不连续.本文采用仿真方法研究存在间谐波/次谐波的同步电机交交变频器的性能,充分考虑其输出电流的不连续性以及输出电流的波动对交交变频器输入电流的影响.针对实验室样机,对输出相电压、相电流、输入电流以及励磁电流中的间谐波进行了估计和实验验证,对典型情况下由间谐波导致的严重转矩脉动进行了确认.仿真结果对于此类装置电能质量以及间谐波/次谐波抑制的研究有借鉴意义.
