CLASSIFICATION OF HVDC LINKS
HVDC links may be broadly classified into the following categories:
- Monopolar Links
- Bipolar Links
- Homopolar Links
The basic configuration of a monopolar link is shown in the figure. It uses one conductor, usually of negative polarity. The return path is provided by ground or water. Cost considerations often lead to the use of such systems, particularly for cable transmission. This type of configuration may also be the first stage in the development of a bipolar system.
Instead of ground return, a metallic return may be used in situations where the earth resistivity is too high or possible interference with underground/underwater metallic structures is objectionable. The conductor forming the metallic return is at low voltage.
