Objectif - To improve the economic viability of wind turbines in the 750-800 kW range especially aimed at installation at inland sites.- To improve the economic viability of wind power plants by introducing a new control system enabling the adjustment of the blade pitch to accomodate requirements as to noise reduction at specific times.- To demonstrate the viability of a wind turbine equipped with a relatively large light-weight rotor designed for inland sites.- To test the functionality of a new control system enabling the adjustment of the blade pitch in accordance with air density, i.e. temperature and pressure, so as to comply with the requirements concerning grid compatibility of wind turbines to improve the possibility of load management.- To improve wind farm production by using the Wincon Powerstall system and the wind farm control system.1. Innovative technology :- The ability to react to sudden increases in wind speed (i.e. gusts) and limit the excess power output from the wind turbine quickly (grid compatibility) without grat stress to the structure.- The avoidance of large seasonal variations in power output due to changes in the air density as a result of diurnal and seasonal changes in temperature and pressure.- The introduction of a predetermined 'low-moise' pitch angle for use at specific hours and times (night hours, weekends, etc.) achieved by adjusting the blades' pitch angle.- The fulfilment of requirements as to load management at times when the grid cannot absorb the full output by way of the Central Monitoring and Control System's ability to monitor the collective data for all three wind turbines and make adjustements to each wind trubine to meet the total plant power output objective.2.Context of the technology :If the EU's objectives for wind energy are to be fulfilled, a consequence of the ever increasing pressure on land for development of wind power plants is that, in future, a relatively large percentage of wind energy development will have to take place ats sites that have so far been deemed unviable for wind power development, i.e. inland sites with less favourable wind regimes. So far wind turbines installed at such inland sites have been modified versions of standard wind turbines (increased rotor diameter) which present problems to the 'conventional' technology due to the relatively large seasonal variations in climatic conditions in many wind turbines experiencing prolonged operation with poweroutputs substantially above rated resulting in shorter lifetimes.
