Synchrophasors Overview

Synchronized phasor measurements (synchrophasors) provide real-time measurement of electrical quantities from across a power system. Applications of synchrophasor measurements include system model validation, determining stability margins, maximizing stable system loading, islanding detection, system-wide disturbance recording, and visualization of dynamic system response. The basic system building blocks are GPS satellite-synchronized clocks, phasor measurement units (PMUs), a phasor data concentrator (PDC), and visualization software.
