风能资源综合评估模型模拟精度检验

Comprehensive Evaluation Model Analysis of Wind Power

本文通过2010年1月1日至12月31日采集的华南沿海地区7座测风塔的100m高度风速与风向的信息,以及其中2座测风塔70m高度风向、风能频率,风速、风功率密度频率的数据。通过对比风能资源数值模拟评估系统MM5模式的模拟数据值与实测值,证明MM5模式可以很好地模拟出我国华南沿海风能资源分布情形,不仅月平均风速结果较为一致,且风速和风向逐时模拟结果与观测值也比较吻合,可以较好地模拟出沿海风速、风向变化规律。就风向、风能频率,风速、风功率密度频率而言,该模式对近地层风速受地形影响的模拟效果要优于受海陆风影响的模拟效果,同时海岸线的复杂程度也对模拟结果有一定的影响。综合而言,MM5模式可以很好的用来对我国华南沿海地区的风能资源量值及分布情形进行精细化评估。

In this paper,it collects wind speed and direction information of acquisition of south China coastal area and a wind tower of 100 m high and 2 seat wind tower 70 m altitude wind direction,wind power frequency,wind speed,wind power density frequency data between January 1 to December 31,2010.It is a proof that MM5 model can well simulate the south China coastal wind power resource distribution situation through comparing the wind energy resource numerical simulation evaluation system MM5 model of simulation data value and measured value,not only monthly average wind speed result is more consistent,and wind speed and wind direction by the simulation results and the observed value is consistent,and it also can better simulate the coastal wind speed,wind direction change rule.That mode of nearly formation wind speed by topography influence simulation effect is superior to influence by land and sea breeze of the simulation effect,With the wind,wind power frequency,wind speed,wind power density frequency character;at the same time,the complexity of the coastline of the simulation results have certain effect is consistent.Comprehensive character,MM5 model can well used to south China coastal areas in the wind energy resource value and distribution in the fine evaluation.
