Synchrophasor Measurement Standard Comparison and Testing of an FF-based PMU

Abstract

Phasor Measurement Units (PMUs) are an integral part of Wide Area Measurement Systems (WAMS). The PMU algorithms need to be tested before they are utilized for monitoring, control and protection applications. In this context, understanding the test procedures suggested by the IEEE standard for synchrophasor measurement is very essential. This paper looks into the standards, with emphasis on the differences between the 2011 version and the 2014 update. In this paper, the IEEE standard based test procedures are listed and detailed in such a way that they can be readily applied to test any PMU algorithm for compliance verification. The steady-state and dynamic tests given in the standard are performed, using the Fourier Filter (FF) algorithm and results are compared with the permissible limits. Finally the performance of the FF is verified using realistic signals obtained from a 4-machine 10-bus system during fault conditions.
