The development of the onshore substation has begun for the Dawn Wind farm, situated off the coast of Lengthy Island, New York, together with work on the laydown staging areas.
Dawn Wind’s transmission system will comprise a subsea export cable that may have a size of 100 miles (161 kilometres) to attach the wind farm’s offshore substation to the grid connection level on land in Holbrook, New York.
The HVDC system consists of two converter stations, one offshore and an onshore substation.
The offshore converter station will accumulate the 66 kV alternating present (AC) energy generated by the wind generators by way of an inter-array cable system and remodel it to 320 kV DC for transmission by way of the subsea export cable to the onshore converter station at Holbrook on Lengthy Island. The onshore substation will then convert the facility again to AC to feed it into the distribution grid.
The HVDC system might be delivered by a consortium between Siemens Power and Aker Options, with Siemens Power chargeable for delivering the system on a turnkey foundation and offering onshore civil work in partnership with native firms, and Aker Options contracted to ship the offshore platform which consists of a metal jacket substructure, and a topside platform deck housing {the electrical} gear.
