Development and construction of an economic and quiet 1.5 MW wind energy converter

In order to achieve maximum economy in terms of cost and energy output the new generation of wind energy converters are significantly larger than their earlier counterparts. This project has contributed further to this situation through the development of a gearless, 1.5 MW machine.

The new generation of wind turbines are significantly larger and more efficient in terms of energy generation than earlier models but, despite their size, operate with minimum intrusion and little noise pollution. The primary aim of this project, which was part of the WEGA ll action aimed at promoting the development of a new generation of wind energy converters, was to design and develop a 1 MW gearless machine with a 55 metre rotor. It was intended that this machine would still be suitable for transportation and erection without the need for special equipment, and would be economical as regards price and electricity output. In the latter stages of this project the design was modified to 1.5 MW and 66 metre rotor diameter. It was perceived that this larger size of turbine would equally be able to fulfil the desired criteria for transport and erection, and would further maximise energy output.
