A Study of Wind Turbine Performance Decline with Age through Operation Data Analysis

摘要: Ageing of technical systems and machines is a matter fact. It therefore does not come as surprise that an energy conversion system such wind turbine, which in particular operates under non-stationary conditions, subjected to performance decline with age. The present study presents analysis the deterioration age Vestas V52 installed 2005 at Dundalk Institute Technology campus Ireland. turbine has operated from October 2018 its original gearbox, subsequently been replaced 2019. Therefore, key point operation data spanning over thirteen years have analysed for estimating how degrades time. To this end, one most innovative approaches control monitoring employed: multivariate Support Vector Regression Gaussian Kernel, whose target power output turbine. Once model trained reference set, degradation assessed by studying residuals between estimates measurements evolve. Furthermore, curve through binning method performed estimate Annual Energy Production variations suggests convenient strategy test case (running gearbox until end life) indeed adopted. Summarizing, main results are follows: ten-year period, declined order 5%; seems be nonlinear pass by; after replacement, fraction recovered, though all because rest operating state. Finally, it should noted basically consistent few available literature.
