SCR and X/R ratio of PLBVFU1 model

retag add tags

I read a post titled 'How to calculate SCR, X/R ratio in PSS/E?' and tried to simulate the LVRT test of a wind farm.

However, when i try to play back voltage of 0pu, the voltage at the POM stays around 0.3pu due to the ZSORCE of the infinite bus generator.

Is there a way to simulate PLBVFU1 model using specified SCR and X/R ratio values?

Skip the SCR and use an infinite generator instead. Increase Mbase and decrease zsorce.

When using PLBVFU1, intention is to apply the required playback at the POC. Use an infinite generator with a very low impedance SCR(9999) branch to play the same voltage and frequency at the POC. Also the Playback generator is a voltage source behind an impedance. To get the same voltage at the terminal make your infinite machine MVA higher or reduce machine impedance (specifically X).
