摘要
论文以Surfer8.0以及地理信息系统(GIS)软件Citystar3.0为平台,利用广东省86个气象站历史测风资料以及沿海72个风能测风塔临时观测资料,计算广东省空间分辨率为1km×1km格点上风能参数,进行了广东省风能资源的宏观区划和风电场选址区划;估算出广东省离地面10m高度上全省及各区划的风能资源理论可开发量为7.50×104MW,技术可开发量为5.89×103MW。为广东省风电开发宏观规划以及大型风电场的微观选址提供了科学而且精细的资源依据。
In the recent 30 years,wind power has become an important energy source because of its contribution to the alleviation of the environmental pollution,and more and more countries have paid attention to the development of this new energy source.By the end of 2004,the total capacity of wind power in the whole world is 47616.4MW with an increasing rate of 21.2% in 2004.The capacity of china is 764.0MW,and the increasing rate is 34.7% in the corresponding period. Wind power in China has stepped into a fast developing stage.However, in China,the main wind resource reference for choosing wind farm states is the wind energy division performed by ZHU Rui-zhao in the 1980＇s which can only give a rudiment result for China＇s wind energy distri-bution,because its data is from weather stations with spatial distance up to 80km.Since wind is a stochastic variant which varies with terrain,underlying characteristics,weather phenomenon and so on,wind energy resource division with high spatial resolution is urgently needed for choosing sites of large-scale wind farms in order to meet the fast developing wind power market.Guangdong Province is rich in wind resource and has good investment environment,and its wind power development takes the lead throughout the country.According to the meteorologic data of 86 stations and the short-term data of 72 observation towers in coastal zone of Guangdong,based on Surfer8.0 and Citystar3.0,wind energy parameters at the lkmxlkm grid are calculated.Macroscopic wind energy division and the division specially for choosing sites of wind farms are performed.The exploitable capacity in theory and practice at 10m height above the ground are 7.50×10^4MW and 5.89×10^3MW,respectively.The result of this study can provide a scientific and detailed reference for macroscopic project planning and microscopic site choosing for large wind farms for wind power development.
