| 摘 要： | 风电场发电量是定量评估拟建风电场效益的重要指标,特别在地形复杂区域,现有风电场发电量计算方法不能较好地反映实际情况。为此,通过对风电场发电量影响因素的分析,引入了物理模型即粗糙度模型和地形模型,考虑了风电场的局部效应对风电场风能资源的影响,采用解析原理分析风电场局地效应与风电机组尾流影响,较为精确地模拟了拟建风电场的风能资源,从而提高风电场的效益。

| Abstract: | Annual Energy Production(AEP) is an important index in quantitative benefit evaluation of planned wind farm.The real situation cannot be reflected by existing AEP calculation methods accurately,especially in complex terrain area.Influencing factors of AEP in wind farm were analyzed;physical models such as roughness model and terrain model were introduced.With the consideration of wind electrical field local effort influence on the wind resources,an analytic method was proposed to analyze the local effect of... |
