IEC的风机选型参数估算方法在中国的适用性研究
Applicability of Estimation Methods of IEC WTGS Selecting Parameters in China
摘要
Abstract
Estimation methods of extreme wind speed and turbulence intensity parameters for wind turbine classes recommended by IEC 61400-1 Ed.3:Wind turbines Part 1:DesignRequirements are widely used in wind energy because of its simple and convenient features.Based on the observation data from 193 masts in the professional observation network of wind energy resource in China,we compare the extreme 10 min average wind speeds within a recurrence period of 50 years (V50 )by IEC method and extremum Ⅰdistribu-tion which is recommended in China,and obtain the following findings.First of all,there are only 7 masts where the values ofV50 by the two methods is relatively consistent within ±1%deviation.Values ofV50 by IEC method are generally smaller,and there are 121 masts withV50 lower than -10% and 44 masts with the value lower than -30%,while only 9 masts have the value higher than +10%all around the country. After that,masts with much smaller V50 by IEC method are mainly distributed in southeastern coastal areas affected by typhoon,while masts with small deviations are mainly distributed in the regions with flat terrain in the Northwest and North China,and the masts with deviation over 10% are also concentrated right here.Finally,46 masts will go into errors if they are calculated only by characteristic indices of the mean turbulence intensity in 15 m·s-1 wind speed,compared to results by the 90% quantile for 15 m· s-1 wind speed.关键词
