WIND TURBINES IN EU
The current status of the european wind energy market, as depicted by the EWEA, can easily show the inherent impact of improving performances of Wind Turbines. Wind has become an integral part of the generation mix of markets like Germany, Spain, and Denmark alongside conventional power sources. Annual wind power installations in the EU have increased from 3.2 GW in 2000 to 11.9 GW in 2012, a compound annual growth rate of over 11%. Wind energy represented 26% of all new EU power capacity installed in 2012, with investments of between €12.8 billion and €17.2 billion.
HOW DOES SOFTWIND WORK?
SoftWind aims at presenting a multidimensional approach to the problem of CoE reduction for large size on-shore wind turbines. This goal will be pursued following this 6 main threads:
The project is predicted to have a significant impact on lowering the CoE, achieved by increasing the technology performance, decreasing operation and maintenance costs, increasing reliability and lifetime of WTs with an eye to environmental impact. As a whole, the main Key Performance Indicator (KPI) can be considered the CoE, and an overall 5% CoE reduction can be foreseen as the expected performance, as a consequence of technology optimization and reduced O&M costs.
Advanced Control Design: Advanced Control design for load reduction, Advanced supervisory control design and Fault management working under dam. cond.
Advanced Materials: selection of hybrid composite configuration and experimental testing (both static and dynamic) on samples of the selected configuration.
Modelling, Co-simulation and Fatigue: flexible multibody modelling and simulation, stress recovery and Fatigue behaviour evaluation.
The main goal is to test and validate the control strategies in term of efficiency in responding to variable speed and capability to relieve dynamic loads.
Development of advanced techniques for damage detection using phased-array UT and SMArt thermography – experimental fatigue test with embedded sensors.
Co-ordination of technical activities and dissemination of results.
