| ABB wins HVDC order in North America ABB, the Swiss engineering group, has won orders worth around $75 million from Hydro-Québec, the utility in eastern Canada, and National Grid, the utility in New England, USA, to refurbish three high-voltage direct current (HVDC) converter stations. The multi-terminal HVDC link between Québec and New England was the world's first such link to be put into service between 1990 and 1992. ABB will now replace the 20-year-old control and protection systems with the newest modular advanced control systems (MACH) for HVDC equipment. The link has a total transfer capacity of 2,000 megawatts of power and spans a distance of 1,500 kilometers from the La Grande II hydroelectric generating complex near James Bay in eastern Canada, via Nicolet, a substation located on the south shore of the St-Lawrence river, down to Sandy Pond, near Boston, Massachusetts in the US. The project scope also includes refurbishment of two cable transition stations and a control and protection system replica for a test center in Canada. The stations are scheduled to go in operation in stages and will be completed by 2016. write your comments about the article :: © 2013 Construction News :: home page |
