摘　　要：目前有多种采用傅里叶算法求取信号谐波分量相量值的方法,使得工程技术人员无从选择。通过严密的数学推导,对相量形式的多样性进行了详细的解释,给出了2种明确的谐波分量相量值求取算法,仿真计算结果证明了结论的正确性和可行性。Currently, a number of methods proposed for calculating the phasors of harmonic components of signals using the Fourier algorithm seem to make electrical engineers puzzled as to which to choose from. Based on strict mathematical deduction, this paper explains the diversity of phasor representation and presents two types of algorithm to represent and calculate the phasors of harmonic components. The simulation results have proved the validity and feasibility of the conclusions presented.
