HVDC Link Ratings for 400 kV Busbars?

AI Thread Summary
The discussion focuses on modeling an HVDC link connected to 400 kV busbars using ETAP 7.5, where users encounter a calculation error related to mismatched voltage ratings. The error message indicates that the HVDC rectifier output or inverter input voltage does not align with the rated kV. Participants seek guidance on appropriate settings for the HVDC link ratings page to resolve this issue. Suggestions include ensuring that the specified rated value does not exceed 400 kV and considering lower values if necessary. Proper configuration of these settings is crucial for successful load flow analysis.

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
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
