摘　　要：针对传统的ＤＦＴ和ＦＦＴ算法的缺陷，讨论改进的受谐波干扰的电信号基波分量快速算法。此算法较大地提高了计算效率，可用于实时控制、无功功率和谐波补偿以及功率和能量实时计算等领域。In the real time measurement and calculation of electrical quantities, such as voltage and current, which include harmonics, the fundamental usually provides basic information of the measured system. Traditional DFT and FFT algorithm can be used for the purpose of fundamental calculation, but with low computational effeciency. This paper discusses a improved fast algorithm for the fundamental calculation which enhances the effeciency greatly. Therefore, it can be used for the real time control, compensation of reactive power and harmonics, real time calculation of power and energy, and so on.
