Project: Maritime Link 500 MW VSC
Service: VSC HVDC
Year: 2012 — 2013
The Maritime Link is a 500 MW +/- 200 kV point-to-point VSC HVDC system connecting the Island of Newfoundland to Nova Scotia via overhead transmission line and submarine cable. The Newfoundland terminal of the VSC link is electrically close to the inverter terminal of a 900 MW 2-terminal LCC HVDC link connecting Labrador to Newfound Island (Labrador Island Link). Therefore, possible interaction of the HVDC links was important to consider. TGS performed the pre-specification studies and developed the technical specification for the Maritime Link VSC converters.
Needed to develop controls to operate the VSC under extremely weak short circuit levels.
