Model of a PMU measuring phasors on a line
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.
The calculated frequency is just an estimate and can deviate by a certain margin of error.
|v_0||Voltage magnitude initial value |
|angle_0||Voltage angle initial value [rad]|
|Ts||Derivative smoothing filter time constant [s]|
|fn||System base frequency [Hz]|
|p||the positive direction of the current is from connector p ...|
|n||... and to connector n|
