Abstract

PMU measurements lose its accuracy due to bias errors and noise in the actual field installation. To maintain the accuracy of measurement taken by a Phasor Measurement Unit (PMU) it is essential to calibrate the device. Instead of calibrating the device each time this paper proposes a method of error detection and an algorithm to correct the measurement on the basis of the Total Vector Error (TVE) concept.

一种PMU测量误差检测和校正方法
由于实际现场安装中的偏置误差和噪声,PMU测量失去了精度。为了保持相量测量单元(PMU)测量的准确性,校准设备是必不可少的。本文提出了一种基于总矢量误差(Total Vector error, TVE)概念的误差检测方法和校正算法,代替了每次校准设备的方法。
