Voltage Measurement Device
Information
StaVmea model in PowerFactory measures voltage and frequency.
The frequency in PowerFactory is computed with respect to the frame rotating with frequency
equal to the synchronous machine.
This is supported via the input omega here.
Most of the OpenIPSL examples do not provide omega of the reference machine and thus,
if the input is not connected the frequency is computed with respect to the 50 Hz reference frame
and filtered to simulate the measurement delay.
