Hello,

I have a problem with playback function. When i playback some pmu measurements, the voltages are played back correctly. However, frequencies are not played back correctly. It's like frequency deviation lags behind the time and also is not correct.

I generate my own .plb file PMU measurements using the measurements on a specific bus.

Is there something I should change while a I generate my own measurements?

Thanks!!!

The bus voltage frequency is calculated from the voltage angle with a filter of normally 40 ms (four time steps). That may explain the lag you see.
