Influence of Wind Speed on Wind Turbine Reliability

Abstract: Wind turbines have been erected in increasing numbers in Europe, the USA and elsewhere. In Europe Denmark has played a particularly prominent part in developing the technology and has installed a large numbers of turbines. The paper is concerned with the influence of the weather on the reliability of modern wind turbines and in particular the effect of wind speed. The prime objective of the work is to extract information from existing reliability data to draw conclusions about how the wind speed affects turbin… Show more

“…The essential reason is that with the same average wind speed, pitch operations are different relating to the various turbulence intensity at full load region. Tavner et al (2006) concerned with the influence of wind speed on the reliability of WT. This research quantifies the wind speed data as Wind Energy Index (WEI) which is defined as data exhibited the highest TIs, moderate wind speeds exhibited moderate TIs and high wind speeds exhibited high TIs.…”

“…From this figure and the research result of Tavner et al (2013), we can conclude that weather and wind speed have significant influence on WT components deterioration and failure. Moreover, Tavner et al (2006) points out that some WT components are more affected by wind speed than others, such as hydraulic system, generator, yaw control and mechanical brake (shown in Figure 4). In the opinion of the author, the reason is that these components are not designed with the rapidly changing effects of the wind speed variation.…”

“…One of the first extensive analysis on the effects of weather on WT reliability was presented by Hahn et al [7], showing increased failure rates of certain WT components with rising average daily wind speeds. In Tavner et al [8] an annual periodicity in failure rates due to seasonal variation in weather conditions is reported, by analysing the correlation between monthly averaged wind speed conditions and component failures. The effects of wind speed on WT downtimes with regards to the turbines' energyand time-based availability is examined by Faulstich et al [9].…”
