Periodic Reporting for period 2 - AWESOME (Advanced Wind Energy Systems Operation and Maintenance Expertise)
Periodo di rendicontazione: 2017-01-01 al 2018-12-31
Every AWESOME fellow benefited from a wide range of network-training activities, aiming to cover all the scientific and technical development branches of wind power O&M, including:
- Wind Power summer school (LBORO, Aug 2015): a series of lectures delivered by academics and industry experts were given.
- Specific Course 1 (CIRCE, Sep 2015): introduced the main challenges of wind power O&M.
- Specific Course 2 (NTNU, Nov 2015): focused on the scientific and technical subjects of wind farm O&M.
- 1st Joint Industry Workshop (RAMBOLL, Feb 2016): 31 participants attended the workshop, where the industry representatives covered various expert fields of the wind industry, like offshore and onshore operator, SCADA data specialist, monitoring system consultancies, turbine and foundation designer and applied research institutes. The researchers gave the technical solution to two current problems defined by these industry representatives.
- Specific Course 3 (Ramboll, Hamburg, Feb 2017): focused on transversal competences as research ethics, scientific dissemination, academic cooperation, research funding, research in industry, negotiation, start-ups and university spin-offs, etc.
The first set of secondments were carried out, most of them in the industry environment, aiming at validating and applying the research work as well as learning from a commercial oriented perspective of wind turbine O&M. The second set of secondments were accomplished mainly in academic environments, aiming collaborating between the internal fellows of the project and also, in some cases, with external researchers.
A total of 49 scientific publications have been achieved. From them, 12 were in conference proceedings and 37 in regular journal papers, mainly in JCR indexed journals. Regarding conferences, there were 45 oral presentations and 18 posters. The AWESOME network was represented in many conferences and events. The members attended the most important wind energy related conferences, TORQUE (2016 and 2018), Wind Europe Conference (2016, 2017 and 2018), EERA Deep Sea Offshore Wind R&D Conference (2016, 2017 and 2018). They also attended other important conferences as COMADEM 2016, ESREL (2017 and 2018), Wind Energy Science (2017), EAWE PhD. Seminars (2017, 2017 and 2018).
The current progress beyond the state of the art can be summarized in terms of the three main objectives, directly related with the three scientific work packages of the project.
Then, related to Wind Farm O&M planning, the project showed advances in the characterization of wind fields large coherent structures and the calculation of the power output for an idealized wind farm with different inflow situations derived from Lidar measurements. A reduced order wind farm model has also been developed together with studies of the influence of repair time and forecast length. All these results will allow to improve the O&M planning of wind farms.
Regarding Maintenance optimisation by prognosis of component failures, advances in the detection of alarm patterns and the characterisation of the normal behaviour of the wind turbines have been done. Different techniques have been used to detect turbine component faults including Gaussian Process Theory, Neural Networks and non-linear supervised and unsupervised machine learning methods.
Finally, with regards to Cost-effective strategies for O&M, reliability models and several frameworks for identifying the influence of weather parameters have been developed. Studies on the fatigue of turbine components, mainly for off-shore wind turbines and the outline of a decision model for Life Time extension have also been done.
