摘要
在实施可持续能源战略中,风能等可再生能源开发利用是重要的战略选择。风能资源评估是其开发利用的关键环节,如何利用有限的观测资料进行资源评估和分析就成为迫切需要解决的问题。本文正是基于此目的, 就复杂地形下风能资源评估进行初步研究,通过对北京大学准静力模式进行改进,并进行数值模拟试验,探讨数值模拟在风能资源评估中的应用。模拟试验结果表明,改进后的模式很好地模拟出复杂地形条件下的流场特征, 对复杂地形条件下的风能资源评估具有很好的指导意义。
Wind energy as a viable source of renewable energy for the 21st century will be played an integral role in Chinese electricity strategy. The research of the assessment of wind energy resource on national or regional level will deal with the questions how to evaluate the distribution of the wind resource in data - sparse areas or in areas of complex terrain and how to hint the general areas where a high wind resource may exist. Aims to develop a technique for estimating the magnitude and distribution of wind resource over a selected area, simulations were run with an improved 3-dimension hydrostatic model for complex terrain which indicates the wind characteristics successfully. It seemed that numerical simulation technique can be utilized in performing the regional wind energy assessments and potential wind turbine sites evaluations in the areas that have high wind resource but where data were previously not available or were very limited.
