HVDC Link Ratings for 400 kV Busbars?

In summary, the conversation is about a user's difficulty in modeling an HVDC link in the etap 7.5 demo. They encounter a calculation error related to the HVDC rectifier and inverter, and are unsure of the appropriate settings to use for the HVDC link ratings page. They ask for an example of settings that would allow the HVDC link to operate with 400 kV busbars. One suggestion is to use a lower or specified rated value.

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
 

1. What is an HVDC Transmission Link ETAP?

An HVDC Transmission Link ETAP is an electrical system that utilizes high-voltage direct current (HVDC) technology to transmit electricity over long distances. It is used to connect two separate power systems, typically at different voltages or frequencies, to allow for more efficient and reliable power transmission.

2. How does an HVDC Transmission Link ETAP work?

An HVDC Transmission Link ETAP works by converting alternating current (AC) into direct current (DC) at one end of the link using a converter station, transmitting the DC power through a cable or overhead line, and then converting it back into AC at the other end using another converter station. This allows for lower energy losses and better voltage control compared to traditional AC transmission systems.

3. What are the benefits of using an HVDC Transmission Link ETAP?

There are several benefits to using an HVDC Transmission Link ETAP, including lower energy losses, increased power transfer capability, and improved stability and reliability of the power grid. It can also help to connect renewable energy sources, such as offshore wind farms, to existing power systems.

4. What are the main components of an HVDC Transmission Link ETAP?

The main components of an HVDC Transmission Link ETAP include converter stations at each end of the link, a transmission line (either underground or overhead), and control and protection systems. Other components may include transformers, filters, and reactive power compensation devices.

5. What are the key considerations when designing an HVDC Transmission Link ETAP?

When designing an HVDC Transmission Link ETAP, factors such as distance, power level, voltage level, environmental conditions, and cost must be taken into consideration. Other key considerations include selecting the appropriate converter technology, ensuring efficient and reliable operation, and complying with regulatory and safety standards.
