Can PSSE be used for CT sizing?
Can PSSE be used for current transformer sizing of a line/generator bay in a switchyard? What are the applicable API and what would be the general procedure to approach the problem.
The idea is to determine the transient performance of the CT. As per the IEEE PSRC report and elsewhere, the highest offset (DC component) of the fault current has to be estimated. The question is - what would be the best way of estimating this DC offset in PSSE, is the BKDY routine appropriate? Can a dynamic simulation give what is required, if so how?
PSSE cannot be directly used for this purpose. However, you could set up a power flow and use the values it generates to help size the CT. Can you be more specific regarding what info you're looking for?
@jsexauer I have edited the question. I hope I have been able to convey what I want.
@amaity Thanks, much clearer. Using PSSE for dynamics is outside of my area of expertise, hopefully someone else can help you.
