HVDC
transmission transmission of electric power (at typically 500–1500 kV)
using DC rather than AC. This can be desirable for several reasons:
1. For economic reasons when a large amount of power is to be transmitted over a long distance, i.e., 300–400 miles, or via
underwater cables;
2. For the connection of asynchronous AC systems; and
3. Improved transient stability and dynamic damping of the electrical system oscillations.
