摘　　要：本文提出了一种将三点式曲线拟合与多点绝对值和补偿的新型频率测量方法。理论分析及数字仿真表明，该方法不受电压过零点的影响，在任何采样点都具有稳定和可靠的计算精度。This paper described a new algorithm for measuring frequency. This method is based on the curve fitting technique with only three points and uses multi point frequency compensating technique to avoid voltage cross zero point errors indroduced by harmonic terms are reduced effectively in the algorithm without filter. Analysis and digital simulation show that the method provides a fast, simple and reliable frequency measurement with accuracy.
