A Comparative Study of Various Methods of Phasor Measurement Unit Algorithms

Phasors are significant to power system analysis in both steady-state and dynamic conditions. IEEE Standard C37.118.1 2011 along with its recent amendment C37.118.1a2014 define synchrophasor measurements with the focus on the behavior of phasor measurement units (PMUs) under steady-state and dynamic operating conditions. The Synchrophasors can find many applications in modern power systems including real-time status monitoring, precise state estimation, validating simulation models, protection, taking centralized control actions using wide-area measurements and integrating renewable and intermittent resources. In this paper, various PMU algorithms are compared to find out the best algorithm which gives best result in specific conditions. As different research papers suggested and focused on different criterions, it was very difficult and cumbersome task to accumulate all data in a common platform and compare them. After vigorous research a unique way is developed to present overall comparison result in a well-defined and more understandable manner.
