Ride Through Settings Testing
Does anyone know how to test the ride through settings (LVRT,HVRT, Over/Under Frequency) of a model? I enter the settings into the dynamic file in "other models" -> "Miscellaneous" specifying the voltage ride through settings as "VTGPAT" and the frequency settings as "FRQTPAT.
I have not been able to test any of these settings directly. I am able to simulate the LVRT (low voltage ride through) results from putting a simple bus fault on a bus but I have not been able to replicate the HVRT (high voltage ride through) or frequency response.
If anyone knows how to test/validate these settings I would appreciate the help, I have been trying to figure this out for a while.
The settings you specified are voltage and frequency protection settings. The inverter or machine will trip when the parameter monitored exceeds/fall below the threshold while satisfying the time delay setting.
Thank you for the response. I understand that is what they are supposed to do but I have to test the inverter going to these parameters and show the model can recover after being at those values for a short amount of time.
for VRT, i have used FIDVR.. place a fault around the inverter a few buses away and clear it based on the protection scheme settings. generally you should see the VTGTPAT instance activated.. For FREQ you can simulate dropping a Gen so the FRQPAT gets activated in the simulation based on underfreq.
