Abstract:

-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.
