Abstract:
The first modern HVDC link connected Gotland Island to the Swedish mainland. Commissioned in 1954, the link was direct current because the distance was too great for alternating current cables to be effective. The AC/DC and DC/AC conversion was enabled by mercury arc valves. By the early 1970s thyristor valves began replacing mercury arc valves, and until recently all systems have employed that technology. Now we have seen a new entry in the field, as gate turn-off family power semiconductors have led to high-level voltage source converters to enable new applications for HVDC links.
HVDC transmission has unique attributes. Examples of these include: Long-distance bulk power transmission was the justification for the first modern-day (1970) HVDC link in the United States: the Pacific HVDC Intertie connecting the Celilo Station on the Columbia River to the Sylmar Station in the San Fernando Valley. Presently the link transmits 3100 MW a distance of 850 miles: its efficiency greatly exceeded that of EHV AC systems.
Soon after (1973), the first thyristor system was commissioned: the 320 MW Eel River back-to-back link. It asynchronously connected New Brunswick to Maine enabling the import of lower-price hydroelectric power. There are now numerous such links along the east-west boundary of the US grid, roughly along the Rocky Mountains (and at other locations). AC interconnections at those locations were not possible because of system weakness.
A consequence of the greatly increased world-wide interest in HVDC is that equipment suppliers are now seeing orders at levels unmatched in their experience. Systems are being planned for off-shore wind energy, long-distance high-capacity links at 800 kV/6400 MW, and multi-terminal meshed (grid) systems.
