The Vestas

Vestas

Vestas Wind Systems A/S is a Danish manufacturer, seller, installer, and servicer of wind turbines. It is the largest in the world, but due to very rapid growth of its competitors, its market share decreased from 28% in 2007 to 12.5% in 2009...

 V90-3MW is a three bladed upwind wind turbine generator that uses pitch control and a doubly fed induction generator (50 Hz version). Vestas has installed over 500 units of this type globally since launch.

The V90-3MW evolved from the V80, but with a number of radical differences, the main one being that an oil cooled generator was used, and a single supplier (Hansen) was used for a new style compact gearbox which now butted up directly to the hub rather than through a low speed shaft.

Its relatively low overall weight was one of its major selling points, with Vestas marketing the turbine as giving 50% more power for roughly the same weight as the V80.
