American Superconductor and GE Energy receive LVRT Solution order for Hawaiian wind farm

7 April 2005 – American Superconductor Corporation and GE Energy, a announced Wednesday that they have been selected by Hawi Renewable Development (HRD) to provide a voltage control solution for the Hawi Wind Farm project located near Upolo Point on the Island of Hawaii.

The solution will include two of AMSC’s proprietary D-VAR systems and ancillary equipment from GE to meet the steady-state and dynamic voltage standards for interconnection of the wind farm to the grid. The solution provides fast dynamic voltage support during electrical faults on the utility grid – thereby allowing the wind turbine generators to ride through low voltage events on the grid they are serving.

“Low Voltage Ride-Through is an important criterion for connection of wind farms and other alternative energy sources to many utility grids,” said Chuck Stankiewicz, vice president and general manager of AMSC’s Power Electronic Systems business. “Our D-VAR based solutions are quickly becoming the industry standard for substation-based LVRT solutions.”

Construction of the HRD wind farm, which will generate 10.56 MW of zero-emission electricity, is scheduled to be completed in November 2005. The wind farm will utilize 16 Vestas V47 wind turbine generators.

“The AMSC team was able to step up and provide a solid technical solution to a tough interconnection problem,” said Robert Treiberg, chief executive of HRD. “We consider the AMSC team to be a premier provider of reactive power solutions in the wind industry today and we are happy to have them as a key member of our project team.”
