摘　　要：提出了在电力系统中正确合理地计量电参数的参数自适应准同步采样法。此方法不仅适用于线性系统,而且在非线性系统中也表现出色。给出了此方法的理论及误差分析,通过计算机仿真结果的分析,可以看出,只进行2次迭代即可达到较高的精度,不仅相对误差大为减小,而且运算次数也相对减少。Proposes the self-adaptive quasi-synchronuous sampling method for proper measurement of electric parameters in electric power system,which is applicable to both linear and non-linear systems.explains the theory behind this theory and its error analysis,indicates through analysis of simulation results that two iterations result in higher accuracy,thereby reducing considerably not only the relative error but also the number of operations.

关 键 词：电力系统 准同步采样法 相对误差 计算机仿真 电参数 高精度测试
