How to convert PSCAD model to PSS/E model ?

edit

@jfconroy I use PSS/E 33.10 which Visual Stuido version and IVF version can I use to wirte a model? any download link?

Your first option should be to try to use the built-in PSS/E model "HVDCPL1", for which you do not need any external compiler or capability to write user-defined models. Purchasing a compiler and learning to write your own models is a significant money&time investment.

@jfconroy Thank you dear jfconroy. What I want to do is write a HVDC Plus Model with five-terminals. Any suggestion?

I would say that the most effective way to model an N-terminal VSC-HVDC system is to use N separate synchronous generators in power flow. Then, in a dynamic simulation, you will need to write a model with those N generators "talking" to each other.
