I am studying a paper by myself. In that paper, some testings has been done which includes Deep voltage dip on 3-phase, 2- phase and single-phase, Medium voltage dip on 3-phase, 2-phase and single-phase & Shallow voltge dip on 3-phase, 2-phase and single-phase from Test 01 to Test 09.

I believe these fault apply to POC bus.

Does anyone know how to apply these deep voltage dip? Thank you very much. I really appreciate your help.

I assume "Deep voltage dip" is a solid fault. Single phase and 2-phase faults can be simulated if sequence data are present in the saved case. See also post Application of Unbalanced Faults in Positive Sequence Dynamic Simulation

Thank you for your help. However, it is the dynamic test.

Search this forum for the "playback" model. Keep the frequency vector constant at 60 Hz, shape the Voltage vector according to the voltage profile required.

Thank you very much. Playback model is very useful. However, I still don't know how to implement the voltage dip on 2-phase and single-phase. For my understand, change the parameter of the model, it will implement 3-phase voltage dip, but how can we implement 2-phase and single-phase voltage dip?
