【摘要】 应用塔式光热电站设计软件模拟圆形散点、方形散点和方形麦田等三种不同排布形式的定日镜场,分析三种定日镜场的光学效率及损失,对比三种镜场的定日镜数量、吸热器功率、储热介质储热功率、占地面积及土地利用率等参数,为定日镜场布置及提高定日镜场效率提供参考。模拟结果显示,圆形散点布置形式的定日镜场整体光学效率最高,在相同电站设计容量条件下其所需的定日镜数量最少,占地面积最小。

【Abstract】 Three types of heliostat fields were simulated by using the tower-type thermal power station design software in different configurations including circle staggered(CRS),square staggered(SQS)and square cornfield(SQC)with an attempt to analyze the optical efficiency and loss of three types of heliostat fields, and compared the parameters of three heliostat fields involving heliostat quantity, heat absorber power, heat storage amount of heat storage medium, floor space and land-use ratio which can provide a reference for layout of the heliostat field and for efficiency improvement of the heliostat field. The simulation results show that the heliostat field in configuration of CRS has the highest optical efficiency, the min. number of heliostats and the smallest floor space under the same design capacity of the power station.
