Hydro Quebec substation gets upgraded

Canada: GE’s Grid Solutions business won a contract to perform key upgrades on Hydro Quebec’s Montagnais substation’s protection and control systems.

At the end of 2018, GE successfully completed upgrades to three 765 kV Fixed Series Compensation (FSC) banks at Hydro Quebec’s Montagnais substation.

GE’s FSC technology installed at the Montagnais substation will maintain power transfer capacity, load division, and system stability.

FSC systems make transmission lines function as if they were physically shorter, which helps utilities move power across great distances in a more efficient manner. As utilities recognize this value, an increasing number of them are upgrading their systems to GE’s FSC technology.

GE technicians and engineers faced the challenge of fitting GE’s industry-leading FSC technology into a system originally designed by another company. Using an existing protection apparatus from the original project, GE brought three 765kV FSC banks online at the Hydro Quebec Montagnais site before the end of 2018.

For generations, engineers at GE have designed series compensation projects that deliver superior performance. Most recently, the industry-leading grid services company developed improved polymer-housed metal-oxide varistors (MOVs) that increase performance and reduce costs of running FSC systems.
