Can wind turbine performance aging be individuated as a declining rate?
The average estimates of wind turbine performance aging obtained in the literature with cumulative data should not lead to the wrong expectation that the performance of a wind turbine can be clearly individuated as a declining of a certain rate year by year.
Are wind turbines aging?
The first studies in the literature regarding the aging of wind turbines are based on the analysis of cumulative data of a vast number of wind turbines: the general principle is attempting a regression between the age and the capacity factor of the analyzed fleet and inquiring if there is a declining trend.
How does wind turbine aging affect nacelle vibration?
There is a substantial agreement in the literature about the fact that wind turbine aging is expected to manifest as a power coefficient decrease, sub-component temperatures and a nacelle vibration increase.
Are wind farms aging?
The output of 282 wind farms is accurately estimated using public wind speed data. Correcting for variability in the weather allows wind turbine ageing to be studied. Onshore wind farm output falls 16% a decade, possibly due to availability and wear. Performance decline with age is seen in all farms and all generations of turbines.
Does age affect wind turbine performance?
In , the public data of 282 wind farms sited in the UK are analyzed and the result is that wind turbines decrease their output by 1.6 ± 0.2 % per year, which is a noticeable amount. A similar approach is proposed in for Swedish wind farms and the achieved estimate of performance decline with age is lower with respect to .
Do wind turbines age?
Correcting for variability in the weather allows wind turbine ageing to be studied. Onshore wind farm output falls 16% a decade, possibly due to availability and wear. Performance decline with age is seen in all farms and all generations of turbines. Decreasing output over a farm's life increases the levelised cost of electricity.
