Description

The Phasor Measurement Unit (PMU, Three-Phase) block measures the frequency, phase, and amplitude of the positive sequence component of the input electrical signal in a three-phase system at a particular sample rate.

The block uses a system clock as the synchronous reference. This information is commonly collected from a GPS in the real world.
