Model of a PMU measuring phasors on a line

Information

This device can be used to simulate a Phasorial Measurement Unit (PMU) designed for estimating the grid's frequency at a local node. Frequency estimates are provided given the following: initial conditions for the node's voltage phasor; nominal frequency value; and time constant associated with the smoothing filter used in derivative calculations.

Note

The calculated frequency is just an estimate and can deviate by a certain margin of error.
