Definition

A wide‑area electrical measurement and monitoring technique that collects time‑synchronized complex phasor measurements of voltage and current (magnitude and phase angle) from geographically distributed sensors (phasor measurement units, PMUs) using a common time reference (e.g., GPS or precision time protocols) to enable direct, coherent comparison of system states across the grid for oscillation
