Early life failure modes and downtime analysis of onshore type-III wind turbines in Turkey (2022)
Journal Article
Sarma, N., Tuohy, P. M., Özgönenel, O., & Djurović, S. (2023). Early life failure modes and downtime analysis of onshore type-III wind turbines in Turkey. Electric Power Systems Research, 216, Article 108956. https://doi.org/10.1016/j.epsr.2022.108956

Operations and maintenance costs, and unplanned downtime accounts for a significant proportion of the total expenditure of windfarms. Therefore, reduction of these costs is essential, which requires a better understanding of the wind turbines' reliab...
