American Superconductor Corporation (AMSC), a leading electricity solutions company, today announced a follow-on order for its proprietary PowerModule-based wind turbine generator control systems from Windtec Systemtechnik GmbH (Windtec), a supplier of large wind turbine components and system technology, based in Klagenfurt, Austria. The PowerModule-based control systems will be utilized in the electrical equipment of 23 wind turbine generators -- each rated at 1.5 megawatts -- which Windtec plans to ship to China and Japan in calendar 2006. AMSC expects to ship the PowerModule PM1000 power converters, which manage and stabilize electricity produced by wind turbine generators, to Windtec in the first half of calendar year 2006.
This order follows Windtec's successful utilization of AMSC's PowerModule PM1000 Product Developer Kit in a wind turbine test bed. PowerModule PM1000 power electronic converters -- which are based on advanced Insulated Gate Bipolar Transistor (IGBT) power semiconductor devices -- provide a platform for designers to quickly develop both hardware and software elements of power conversion systems ranging from 60 kilowatts to multi-megawatts for a wide array of applications.
"The ability to modify the PM1000's standard software in order to accommodate Windtec's unique requirements allowed us to focus our development efforts on wind turbine systems instead of on IGBT-based power converter development," said Gerald Hehenberger, President of Windtec. "This has also allowed us to focus more resources on the introduction of advanced control technologies into the market -- a change that we believe gives us a competitive edge in the fast-growing market for wind generation of electricity."
From 1990 to 2002, wind was the fastest growing power source worldwide on a percentage basis, with an annual average growth rate exceeding 30%, according to the American Wind Energy Association. They also note that in 2004 world wind capacity reached 47,317 MW. AMSC participates in this growing market both through sales of its Dynamic-VAR, or D-VAR(R) systems, which allow wind farm developers to meet the standards for interconnecting wind farms to power grids, and through sales of PowerModule-based wind turbine generator control systems, which are incorporated directly into wind turbines.
"We have been working closely with Windtec to develop innovative solutions for wind customers around the world," said Greg Yurek, chief executive officer of AMSC. "This follow-on production order demonstrates the success of AMSC's PowerModule PM1000 power converters and PowerModule Advanced Configuration Tools to rapidly develop solutions for the wind generation industry."
