Understanding the failure behaviour of wind turbines (WTs) can significantly enhance operation and maintenance processes and is essential for developing reliability and strategic maintenance models. Previous research has shown that especially the environmental conditions, to which the turbines are exposed to, affect their reliability drastically. This paper compares several advanced modelling techniques and proposes a novel approach to model WT system and component failures based on the site-specific weather conditions. Furthermore, to avoid common problems in failure modelling, procedures for variable selection and complexity reduction are discussed and incorporated. This is applied to a big failure database comprised of 11 wind farms and 383 turbines. The results show that the model performs very well in several situations such as modelling general WT failures as well as failures of specific components. The latter is exemplified using gearbox failures. 000078962 536__ $$9info:eu-repo/grantAgreement/EC/H2020/642108/EU/Advanced Wind Energy Systems Operation and Maintenance Expertise/AWESOME$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 642108-AWESOME 000078962 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000078962 590__ $$a3.125$$b2018 000078962 591__ $$aENGINEERING, MECHANICAL$$b26 / 129 = 0.202$$c2018$$dQ1$$eT1 000078962 591__ $$aENERGY & FUELS$$b50 / 103 = 0.485$$c2018$$dQ2$$eT2 000078962 592__ $$a1.047$$b2018 000078962 593__ $$aRenewable Energy, Sustainability and the Environment$$c2018$$dQ2 000078962 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000078962 700__ $$0(orcid)0000-0003-2360-0845$$aMelero, Julio J.$$uUniversidad de Zaragoza 000078962 7102_ $$15009$$2535$$aUniversidad de Zaragoza$$bDpto.
