Zusammenfassung: | It is highly preferred to evaluate evolution of wind extremes over long time-scale with nonstationarity extreme distribution model. The annual extreme value methods, which single out the maximum wind of each year as sample data, are utilized. Thereafter, the annual wind extremes are test for nonstationarity. Finally, the maximum possible wind extreme is calculated with generalized extreme value distribution model to evaluate the influence of nonstationarity of wind extreme on safety of wind turbines. It is uncovered that the wind extreme in Hailisu, Guaizihu and Chengshantou are non-stationary. However, there is no maximum possible wind extreme and it is a positive impact on the safety of wind turbines. The wind extreme of Hengshan is stationary. The wind extremes of Huangshan is non-stationary and the maximum possible wind extreme over there is 41.416 m/s, which is notable larger than the design wind speed of 37.5m/s of wind turbines. It is of negative impact on the safety of wind turbines. |
