Abstract：
Wind turbines are known to produce shadow flicker by interruption of sunlight by the turbine blades. Known parameters of the seizure provoking effect of flicker, i.e., contrast, frequency, mark-space ratio, retinal area stimulated and percentage of visual cortex involved were applied to wind turbine features. The proportion of patients affected by viewing wind turbines expressed as distance in multiples of the hub height of the turbine showed that seizure risk does not decrease significantly until the distance exceeds 100 times the hub height. Since risk does not diminish with viewing distance, flash frequency is therefore the critical factor and should be kept to a maximum of three per second, i.e., sixty revolutions per minute for a three-bladed turbine. On wind farms the shadows cast by one turbine on another should not be viewable by the public if the cumulative flash rate exceeds three per second. Turbine blades should not be reflective.
摘要：
已知风力涡轮机通过涡轮机叶片中断阳光而产生阴影闪烁。已知参数的癫痫发作引起闪烁的影响，即，对比,频率,标记空间比，将受刺激的视网膜面积和所涉及的视觉皮层百分比应用于风力涡轮机特征。受风力涡轮机影响的患者比例以涡轮机轮毂高度的倍数表示，在距离超过轮毂高度的100倍之前，癫痫发作风险不会显着降低。由于风险不会随着观看距离而减少，因此，闪光频率是关键因素，应保持在每秒3，即，三叶片涡轮每分钟60转。在风电场上，如果累积闪光速率超过每秒3个，则公众将看不到一台涡轮机投射到另一台涡轮机上的阴影。涡轮叶片不应反光。
