How does PWM contol Inverter that is connected to the grid? How do we decide the V refference?

I understand that when inverter change DC voltage(ex:PV voltage) to AC voltage, we need to condition the frequency and voltage to be the same level as the grid. We can use PWM for this. I study...

How do you determine events as good quality only from catalog data (when the waveform data is not available)?

I attach the catalog data header to make things clear. From this catalog data I want to specifically relocate every 'good' events using hypoDD at a certain depth target (let say 2-4 kms below datum).
