摘要
定日镜在追日过程中的聚光精度是影响塔式太阳能热发电系统工作效率的重要因素之一.分析了塔式太阳能热发电系统中定日镜的运动规律.利用光学反射原理建立定日镜运动轨迹模型,并以我国西部某市作为算例,根据太阳轨迹运算法则以及定日镜与吸热器之间的相对位置,对该地春分日与冬至日定日镜的运动轨迹进行仿真与分析,得到所仿真定日镜的运动规律.
The accuracy of sun-tracking methods for heliostats is one of the most important factors that influences the efficiency of solar tower power plant. Regarding the motion laws for heliostats in solar tower power plant, a model of motion trails for heliostats is developed with optical reflection principle. Based on the relative location between heliostats and the receiver, simulations of motion trails for heliostats of a city in West China are performed under the solar position algorithm on Spring Equinox and Winter Solstice. The results show motion laws for heliostats in solar tower power plant.
