German independent testing organisation TÜV Rheinland has given its stamp of approval to compatriot Winergy’s HybridDrive gearbox-and-generator concept.
GL2010 certification clears the way for the transmission system – a compact two-speed gear and permanent-magnet generator assembly – for first
installation in W2E Wind’s new 3MW W2E-120/3fc wind turbine.
are very satisfied that the HybridDrive system was able to be so quickly
certified,” says Winergy project manager Matthias Deicke.
a consequence, we can offer [a design that] has been checked and verified
regarding basic production criteria and specification features even before a
turbine is engineered. This saves our customers a substantial amount of money
in the complete type certification process.”
34-tonne HybridDrive – which tested at a rated efficiency of over 96%, with the
gearbox and generator achieving individual efficiencies of some 98% – can handle
torque of some 2,550 kilonewton
Designed for turbines with a rotor diameter
of 120 metres, other sizes and power ratings of the HybridDrive are on the
first 3MW wind turbines under license from W2E are expected to be outfitted
with HybridDrives “in the coming months”.
Winergy has a drive-train portfolio ranging over power ratings from 750kW to
