A method for error detection and correction of the PMU measurements

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.
