HVDC Link Ratings for 400 kV Busbars?

Click For Summary
SUMMARY

The discussion focuses on modeling an HVDC link using ETAP 7.5, specifically addressing a calculation error related to mismatched voltage ratings. The user encounters an error stating "Calculation aborted due to HVDC rectifier output or Inverter input kV not matching rated kV" when attempting to connect the HVDC link to 400 kV busbars. The key conclusion is that the settings for the HVDC link ratings must align with the specified rated values or be set to a lower value to resolve the issue.

I have been using etap 7.5 demo and have been trying to model an HVDC link connected to 2 buses and conduct a load flow analysis (there is also a generator in swing mode attached to one bus and a normal transmission line connecting the two buses to satisfy the simulation requirements), but it comes up with a pop up error saying calculation error "Calcluation aborted due to HVDC rectifier output or Inverter input kV not matching rated kV".

I am unsure of what settings to use for the ratings page for the HVDC link. The busbars I am connecting to are set to 400 kV.

Does anyone have an example of settings for the HVDC link ratings page that would allow this to operate ?

Thanks

maybe your value 400kv out of range?
use specified rated value or lower value
