| 摘 要： | 在功率因数的数字化测量中，由于电网频率波动造成非同步采样，从而影响功率因素测量的准确度，本文首次将一种快速收敛潮流算法一改进非线性潮流算法，应用于功率因素的数字化测量中，在准确度误差不超过0，0003的条件下，计算时间却小于10ms，满足功率因素在线监测的同时，还可以实时检测系统频率，为同步采样提供了一条新的途径。

| Abstract: | In the digital measurement of power factor, the measurement accuracy will be influenced by leakage error,because of the fluctuation of the system frequency.This paper firstly applies the improved method of power flow to the digital measurement of power factor and successfully solves the antinomy.Experiments show that the maximum measurement error is limited to 0.0003,but it takes less than 10 ms for one calculation.At the time,it can measure the power frequency in real time so it can give a new way to sample synchronously. |

| Keywords: | power factor higher-order sine fitting algorithm the improved power flow method of nonlinear term |
