The 22 pages that link to High-voltage direct current, each with the reason it gives.

• Alternating currentCompared with: HVDC can outperform AC on very long or underwater transmission links.

• Electric power transmissionCompared with: It can move power efficiently over very long distances and submarine cables where alternating-current links are less suitable.

• Electric power systemCompared with: HVDC offers an alternative to AC for some long-distance and asynchronous connections.

• Electrical gridCompared with: HVDC links can connect asynchronous grids where ordinary AC ties cannot.

• Electric power distributionCompared with: It is used for long-distance bulk transfer rather than ordinary local distribution.

• Three-phase electric powerCompared with: HVDC can outperform three-phase AC on some long-distance or submarine routes.

• Overhead power lineCompared with: HVDC is an alternative for some long-distance links, while conventional overhead grids usually use AC.

• Transmission lineCompared with: HVDC links can move bulk power where conventional alternating-current lines are less suitable.

• Utility frequencyCompared with: It links grids without requiring their alternating-current frequencies to match.

• AC powerCompared with: HVDC can outperform AC on very long routes and undersea cables.

• Wide-area synchronous gridCompared with: HVDC can transfer power across regions without requiring their generators to remain synchronized.
