ABB has completed the Maritime Link, formally handing over the interconnector to Emera, energy and services company headquartered in eastern Canada.
The link made history on December 8, 2017, by conducting the first exchange of electricity between the islands of Newfoundland and Nova Scotia. It went into service on January 15, 2018 as ABB continues to work with Emera and the system operators in each province during initial operation.
The Maritime Link is a 500 megawatt (MW) high-voltage direct current (HVDC) connection that will enable clean, renewable energy, generated in Newfoundland and Labrador to be transmitted to the North American grid in Nova Scotia reducing dependence on fossil fuels.
The HVDC Light technology, used in the design of the Maritime Link, is the first bipolar configuration of its kind in the world using proven and reliable Voltage Source Converters (VSC).
The converter stations are equipped with the ABB Ability based advanced MACH control and protection system which acts like the brain of the HVDC link. It monitors, controls and protects the sophisticated technology in the stations and manages thousands of operations to ensure power reliability. Its advanced fault registration and remote control functions also help protect the link from unexpected disruptions, such as lightning strikes.
“Our proven HVDC Light technology will enable the historical Maritime Link project to integrate and deliver clean renewable energy while enhancing grid stability and enabling power sharing,” said Patrick Fragman, head of ABB’s Grid Integration business, a part of the company’s Power Grids division. “HVDC transmission, a technology we pioneered and lead, is an important element of our Next Level strategy, reinforcing our position as a partner of choice for enabling a stronger, smarter and greener grid.”
In addition to the two converter stations for the ±200 kilovolt (kV) HVDC link, the project scope also includes two 230 kV alternating current (AC) substations in Newfoundland, one 345 kV AC substation in Nova Scotia and two cable transition stations.
