Phasor Measurement Units (PMUs), which measure voltage and current synchronized phasors (synchrophasors), along with frequency and rate of change of frequency (ROCOF), are the emerging measurement devices for power network monitoring. Introduced in the late 1980s and first deployed in experimental systems in the early 1990s, they are now assuming a key role in protection and control of modern electric grids, in particular for state estimation in transmission networks.
