2020-12-14 19:57:19 -0500 asked a question HVDC Power Oscillation Damping Test model

Hi, I have been worked in Power Utility

LCC HVDC project are on going and we received the PSS/E UDM model from GE It has Power Oscillation Damping controller in PSS/E model, and we want to test its function whether it works well or not However, It is difficult to make its phenomenon artificially(power oscillation)

Is there any dynamic model to inject or generate power oscillation artificially??

Thank ou
