摘　　要：鉴于传统的相量测量方法在精度和实时性方面不能很好地统一,提出了一种基于改进三点算法的相量测量方法,该算法采用多个采样点绝对值,选取合适的等间隔采样点,采取平均平滑补偿措施,有效地降低了随机噪声对测量结果的影响,计算精度较高,并对纹波有一定的抑制能力。通过MATLAB软件进行仿真验证,结果表明所提方法是正确可行的。In consideration of unfavorable integration between precision and real-time of conventional methods for phasor measurement,a phasor measurement method based on improved three-point algorithm is presented.It adopts a plurality of absolute values of sampling points,chooses proper evenly-spaced sampling points and takes average smooth compensating measures.In so doing,influence of random noise on test results is effectively reduced,higher calculation accuracy and capacity of ripple suppression are acquired.Through simulation verification by MATLAB,it is demonstrated that the proposed method turns out to be correct and feasible.
