摘要
得出了一种将三点式曲线拟合与多点绝对值和补偿的新型正弦量交流采样算法，理论分析及数学仿真表明，该方法不受频率偏差及电压过零点的影响，在任何采样点都具有稳定、可靠的计算精度，且算法自身对谐波有一定的抑制能力。
This paper described a mew algorithm for measuring Voltage. This me hod is based on the curve fitting technique with only three points and uees nwlti-point valtage compen-sclting technique to avoid coltage crosszero point effectively in the algoritym without filter.Analysit and digifal simuIation show that the method provides a fast;simple and reliable vdtage measurement with accurdcy.
