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不仅适用于线性系统、而且在非线性系统中也表现出色。文中给出了此方法的理论依据及误差分析 ,通过对计算机模拟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。Self-adaptive sub-synchronous sampling, which is for correctly and reasonably testing eletric parameters in a electric power system, is put forward here. It suits both linear and nonlinear systems. The theory and the error analysis for this testing method are presented. The analysis of the testing results based on computer simulation, indicates that only twice linear iteration can results in hight testing accuracy together with less relative error and calculating time.
