Detailed Solution
Download Solution PDFHVDC transmission system:
The massive transmission of electricity in the form of DC over long distances by means of submarine cables or overhead transmission lines is the high voltage direct current (HVDC) transmission.
The AC power is generated in the generating station. This should first be converted into DC. The conversion is done with the help of a rectifier.
The DC power will flow through the overhead lines. At the user end, this DC has to be converted into AC. For that purpose, an inverter is placed at the receiving end.
Advantages of HVDC transmission:
- Minimum line power losses
- No skin effect
- Good voltage regulation
- Less corona loss and radio interference
- Reactive power compensation is not required
