多因素影响下的风机闪烁光影分析与应用

Analysis of Flickering Light and Shadow of Wind Turbines considering multiple Influencing Factors and its Application

评价风机闪烁光影的影响是风电场顺利建设及运行的一项重要内容。在考虑风速、风向和辐照强度等约束影响下,通过计算南北回归线之间的某地区风机叶片旋转产生的闪烁光影对周围敏感点的影响,精细化风机闪烁光影计算模型,并经WindPro软件验证了该模型的正确性;根据计算获得的光影长度和角度,分析了避免风机闪烁光影对周围敏感点影响的措施。

Evaluation of the influence of flickering light and shadow of wind turbines is an important task for the smooth construction and operation of wind farms. Considering constraint factors such as wind speed, wind direction and solar radiation intensity, the calculation model of flickering light and shadow of wind turbines is refined by calculating the influence of the flickering light and shadow due to the rotation of turbine blades on the surrounding sensitive points in a certain area between the Tropic of Cancer and the Tropic of Capricorn. The correctness of the model is verified with WindPro software. Then, engineering measures to avoid the influences are analyzed according to the calculated length and angle of the flickering light and shadow.
