AMSC Books Order for Wind Farm Voltage System

March 01, 2005 by Jeff Shepard

American Superconductor Corp. (AMSC, Westborough, MA) announced the sale of its D-VAR® voltage regulation system to the prime contractor for a Nebraska-based wind farm -- the seventh time customers have chosen AMSC's products to reliably and safely interconnect major wind-generated power facilities to the electrical transmission grid.

The Ainsworth Wind Turbine Project will be located south of Ainsworth, NE, and is owned by Nebraska Public Power District. The project will comprise 36 Vestas V82 wind turbines with an installed capacity of 60 MW, and will be constructed on behalf of the Nebraska Public Power District by RES America Construction Inc. (Austin, TX).

The D-VAR system, slated to be commissioned this summer, constantly monitors voltage where the wind turbines connect to the transmission grid. Instead of allowing voltage to vary as the wind fluctuates, the D-VAR system and its ancillary equipment dynamically regulate the voltage at the point of connection to the transmission grid to a desired level.
