Abstract: |
Synchrophasors are time-synchronized electrical
measurements that represent both the magnitude and phase
angle of the electrical sinusoids. Synchrophasors are
measured by fast time-stamped devices called phasor
measurement units (PMUs) to constitute the basis of realtime
monitoring and control actions in the electric grid.
Due to its enhanced situational awareness capabilities,
many applications of PMUs are presented in the literature
in the past decades. This paper presents a comprehensive
summary of synchrophasor technology, its architecture,
optimal placement techniques and its applications in electric
power transmission and distribution systems. These
applications include wide-area situational awareness and
monitoring, state estimation, fault location and protective
relaying, islanding detection etc. This review also covers
some of the existing challenges in its implementation and
its potential applications. |
