摘要
以定日镜轮廓向地平面投影法计算定日镜镜面的阴影与遮挡损失。定日镜有效面积还受镜面破损、运行故障比例和镜面遮盖损失的影响,因此引入修正因子,得出一种定日镜场总有效镜面面积的评估方法。以宿迁200 kW塔式太阳能光热电站的定日镜场为例,计算定日镜场在4个典型日的阴影与遮挡效率,进而得到定日镜场的平均有效镜面面积。
In this paper,the flat-ground-plane projection model proposed in our previous study is applied to calculate the shading and blocking loss between the neighboring heliostats.Since the effective area is influenced by the mirror surface damage,operation failure ratio and mirror cover loss,a correction factor considering those factors is introduced into the model to calculate it.Taking the heliostats field of the 200 kW solar thermal power tower plant in Suqian as the study case,the shading-blocking efficiency of the heliostats field is calculated under typical conditions of four solar term days,and accordingly the average effective area of the mirrors is obtained.
