| 摘 要： | 利用NCEP 1°×1°再分析资料,采用中尺度模式MM5及诊断风场模型CALMET,对2009年6月—2010年5月甘肃省酒泉地区风能资源进行了数值模拟研究。结果表明,远离山体且地势平坦的地区,模拟的风速与实测风速的误差较小,地形复杂的地区误差偏大。用于对比的10座风塔中有7座在70m高度处的相对误差基本在10%以内,3座相对误差稍大但都在20%以内。风速和风功率密度的季节变化在春季最大,冬、秋季次之,夏季最小。这种季节变化与地形地势及所受的天气系统有密切联系。在酒泉地区随着高度的增加,风速逐渐加大;在河西走廊西端和酒泉北部等海拔较低的地区风速随高度增加的趋势尤为明显。通过对模拟年度风速误差的分析,得到模拟年度在酒泉地区属于大风年,若分析酒泉地区多年平均风况,还需要对模拟结果进行订正。 |

| Abstract: | The wind energy resources of 1 km×1 km resolution in Jiuquan region in Gansu Province from June 2009 to May 2010 was simulated using the mesoscale model MM5 combined with wind diagnosis field model CALMET and 1°×1° reanalysis data of NCEP.The comparison of the simulated and observed wind speeds shows that the relative errors of flat site and away from the mountain are smaller,the complicated topography is bigger.The relative errors in seven wind towers of ten wind towers are no more than 10%,the values of other three towers are within 20% too.The seasonal changes of wind speed and wind power density display that the data of spring is the biggest,then autumn and winter,and the summer is the smallest.This seasonal variation has a close relation with terrain,physiognomy and affected weather system.The wind speed increases with the increasing of height in Jiuquan region,especially in low latitude area,namely the most west part of Hexi corridor and north part of Jiuquan.Through the analysis of wind speed representativeness in the simulated year,there is stronger wind in Jiuquan region in the simulated year.If the average wind state is further analyzed,some correction of the simulated results should be done. |
