Technology Spotlight: Wind Turbines - Renewable Energy World - 0 views
-
At the recently held EWEC 2009 wind energy conference and exhibition most exhibitors agreed that while there has been a substantial business slowdown due to problems linked to obtaining wind project financing, an upturn in demand during the second half of 2009 is beginning to play out, at least in the U.S. Other exhibitors, on the other hand, were a bit more cautious pointing out that substantial numbers of unsold turbines from framework contracts failing to secure project finance are now floating on the wind market. Most interesting from a wind technology point of view is the V112-3.0MW switch away from a compact V90-3.0MW integrated gearbox and main bearing assembly to a 3-point gearbox support. The application of a permanent magnet (PM) type generator with full converter system in the V112-3.0MW is new for Vestas but not for the wind industry. New Technology Trends In what many wind industry insiders consider a major development trend, French aerospace companies EADS Astrium & EADS Composite Aquitaine announced their formal entrance into the wind industry. The French companies offer the wind industry advanced composite materials engineering, manufacturing and related know-how as well as rotor-blade manufacturing capacity.
