| 摘 要： | 提出了线性菲涅耳反射装置中太阳跟踪倾角的计算方法。该聚光装置中每一个反射镜面(简称镜元)需实时跟踪太阳,使太阳入射光反射至固定位置的线性吸热器上。但是,从目前的太阳位置算法中得到的太阳高度角、方位角并不能直接用来控制跟踪,必须进行复杂计算,得到每一镜元相应的跟踪倾角,然后控制电机使其旋转至相应位置。通过将太阳矢量适当分解,简化计算得到适合于菲涅耳太阳能聚光装置反射定位的旋转倾角并经实验验证。

| Abstract: | A vector algorithm of sun tracking tilt-angle of linear fresnel reflector(LFR) was presented.Current algorithms of solar position just can obtain azimuth and altitude which could not be utilized directly by LFR tracking.Farther complex derivation must be done for obtaining relevant tracking tilt-angle by which every mirror element of LFR is controlled rotating to corresponding position.The derivation of tracking tilt-angle was simplified by appropriately decomposing the sun vector. |
