34/150kV Substation Noordzeewind

Strukton Systems’ business unit Energy Solutions built the substation for the offshore Noordzeewind wind farm. This wind farm is operated by Nuon (Vattenfall) and Shell. The substation was built in the dunes at the premises of a steel production plant in Egmond aan Zee, the Netherlands.

Project details

Three stings with a nominal voltage of 34kV connect the wind farm to the substations. The offshore wind farm consists of 36 wind turbines with a rating of 3MW each. A 34kV gas insulated switchgear is connected to a 120MVA 34/150kV step-up transformer installed indoor. The transformer is naturally air-cooled and the coolers are installed on the roof. The air-insulated 150kV switchgear is installed indoors.

Strukton also designed and built the substation itself including the terrain works. A special cooling principle was designed to keep the indoor installation free from contaminated particles using special louvers. Strukton Systems designed and programmed the control and protection of the substation according to the latest standards. Strukton completed testing and commissioning of the substation in the summer of 2006.

Strukton Systems’ scope of supply of services consisted of engineering, procurement, construction, testing and commissioning and certification of the complete system.
