ABB has accomplished a 500 MW high-voltage direct present hyperlink in Canada.

The Maritime Link will likely be operated by Emera, an power and providers firm headquartered in jap Canada, and can carry renewables-generated electrical energy from Newfoundland and Labrador to the North American grid in Nova Scotia.

The hyperlink made historical past in December when it performed the primary alternate of electrical energy between the islands of Newfoundland and Nova Scotia.

It went into service in January and has now been formally handed over to Emera.

The HVDC Light® expertise used within the design of the Maritime Link is the primary bipolar configuration of its form on the earth utilizing voltage supply converters.

ABB mentioned this answer enhances system availability, reduces losses and will increase grid reliability, as energy continues to movement even when one conductor or converter isn’t in use.

The converter stations are outfitted with the ABB Ability™ primarily based superior MACH™ management and safety system, which ABB mentioned “acts just like the mind of the HVDC hyperlink. It screens, controls and protects the delicate expertise within the stations and manages 1000’s of operations to make sure energy reliability. Its superior fault registration and distant management capabilities additionally assist defend the hyperlink from sudden disruptions, similar to lightning strikes.”

Patrick Fragman, head of ABB’s Grid Integration enterprise, mentioned the Maritime Link would “combine and ship clear renewable power whereas enhancing grid stability and enabling energy sharing”, in addition to “a stronger, smarter and greener grid”.

In addition to the 2 converter stations for the HVDC hyperlink, the venture scope additionally contains two 230 kV alternating present substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations.

ABB has been awarded roughly 120 HVDC initiatives which it says represents a complete put in capability of greater than 130,000 MW and accounts for about half of the worldwide put in base.
