摘　　要：针对牵引供电系统三相/单相供电特性,提出了一种检测谐波的新方法,该方法克服了现存单相系统谐波电流检测法计算复杂、运算量大的缺点,能够实现任意次谐波的单独分析;在LabVIEW平台上易于实现,可用于实际工程问题。经过仿真及实验分析结果表明,该算法能够有效地对任意次谐波进行检测,并能准确显示谐波相位。For the characteristics of three-phase and single-phase power supply of traction power supply system,a new method is proposed.This method overcomes the shortcoming of the existing single phase system,which can be used for the calculation of the complex and large computation.It is easy to be realized in Labview platform and can be used in practical engineering.The simulation and experimental results show that the proposed algorithm can detect any harmonic effectively and show the phase of the harmonic accurately.
