Objective
The aim of this project is to test and validate the new VERGNET GEV 16/75 wind turbine equipped with an innovating and economic (1100 FRF per unit) epoxy blade articulation, on a particularly windy (9.41 m/s) site of La Desirade, FWI.
This major innovation, compared to current GEV 15/60, has permitted to lower investment cost by 25% by increasing productivity, and operating cost by 12%, by increasing lifespan of major components.
It also allows significant lowering of noise level (by 3db(A)). It will be tested on four GEV 16/75, on extreme site of La Desirade, regularly subject to hurricanes and tropical storms.
The demonstration of the essential contribution of this innovating disposition will be realised in real conditions : suppression of the effects of bending moments, flutter, of twist movements, of gyroscopic moments and of transmission of blades vibrations to the rest of the machine.
This new machine comes within the scope of Vergnet's conception, that is to say :
- light machine,
- various applications,
- simple,
- of lowest maintenance,
- can be lowered for maintenance and in case of cyclones.
Its target price is 4500 FRF/kW machine or 8000 FRF/kW installed anywhere in the world, that is to say 25% reduction on cost of systems currently available on difficult sites in this power range.
The project consists in installing 4 of these new performant wind turbines, connected to the grid on the site of Vergnet wind farm of La Désirade in Guadeloupe (This wind farm has been realized in 1992 with the help of the European Commission).
This project benefits from various favourable elements :
- an innovating construction with epoxy blades articulations, which allows to increase both power and life span of the wind turbine GEV 15/60 (15 m diameter, 60 kW, 13.5 m/s) up to more than 25% without increasing the cost, and thus an effective reduction of 25% of the cost of installed kW.
- a perfectly well-known wind (four years measurements), particularly important (9.41 m/s mean wind speed).
- extreme climatic conditions (zone subject to hurricanes)
- high cost of conventional sources of energy
- technical presence on site, which will allow to follow the operation of the wind farm in terms of performances as well as of maintenance costs which should be significantly reduced (12% foreseen).
The innovating design consists in epoxy blade articulations : Use of epoxy blade articulation has been tested in Lastours and is conclusive in terms of global behaviour of the wind turbine, in its movements of both pitching and twisting. This flexible articulation is given by geometric rigidity of the blade due to centrifugal forces when the turbine spins.
Stability of the wind turbine, vibrations and aerodynamic noise have considerably been improved, particularly during regulation.
