V90-1.8 MWThe North American variant
Built on experience∤ This wind turbine is the North American variant of the
V90-1.8 MW, which was introduced in Europe in 2004, with over 1,000 units now in operation world wide.
∤ Based on the proven V80 variable speed technology in operation around the globe since 2001.
∤ Designed to maximize energy capture for medium wind regimes (IEC IIA) to further improve upon the V80 reputation as a reliable performer
Features include∤ 90-meter rotor based on 44 meter blade design tech-
nology developed for the Vestas V90-3.0 MW turbines.∤ New 60 Hz generator is a 6-pole design which utilizes
a lower gearing ratio.∤ Primary bed frame structure made from casting to
optimize load transfer to tower, and increase overall frame stiffness.
∤ Improved main bearing housing design for increased structural stiffness.
∤ Standard LVRT (Low Voltage Ride Thru) capability to provide continuous operation through grid faults.
∤ Complete variable speed capability with VCUS™ (Vestas Converter Unity System) technology.
∤ Powered service platform as standard.
