利用MM5模式对阿拉善右旗风能资源进行模拟初探

Using the MM5 model to simulate the wind energy resources in Alxa Youqi,Inner Mongolia

文章选取内蒙古阿拉善右旗作为分析对象,利用中尺度数值模式MM5来模拟2007年1月1日—12月31日的风速(每小时),然后利用统计学方法模拟该地区每天24h的风速,求出日平均风速,再与其附近地区台站实测数据进行比较,从而评估得出该模式的模拟效果:2007年全年的模拟和实测平均风速总体相对误差为34.02%,其中以3—9月份模拟效果最佳,相对误差率最大不超过15%,绝对误差都在0.5m·s^(-1)内。

This article selects Inner Mongolia Alxa Youqi as the research object , using the mesoscale numerical model MM5 simulations wind speed （per hour） of 1 January - 31 December 2007 , then using the statistical method to simulate the daily wind speed of 24 hours ,and calculate the daily average wind speed , comparing with the measured data area near stations, to assess the model simulation results are obtainedSimulated in the whole year of 2007 the average wind speed and overall relative error of the measured average wind speed is 34.02%, and the simulation efect of 3 ~ 9 months is the best, the relative error rate is under 15%, the absolute error is within 0.5 m·s-1.
