摘　　要：设计并建造直径17．70m的碟式聚光装置，抛物镜面焦距为9．49m，采光面积204m^2。结合25kW碟式聚光装置的研制经验，对聚光装置的部分结构进行新尝试，包括镜面单元采用铝蜂窝板基体，高度角机构采用下置式，镜面单元安装采用激光定位等。研制水冷平面接收靶，在视日跟踪状态对聚光装置焦平面的聚焦光斑进行测试，验证镜面单元安装及视日跟踪的有效性。配置S260型斯特林发电系统，运行表明DS-CSP系统的净输出功率与太阳直射辐照度（DNI）基本呈正线性比例关系，数据中DNI最大值为761W／m^2，此时DS-CSP系统的净输出功率可达40．5kW（测试时有效采光面积200m^2），其光热转换效率为26．6％。Diameter 17.70 m solar dish concentrated device has been designed and manufactured, the focal length of the parabolic mirror is 9.49 m and the lighting area is 204 m^2. Combined with the experience of the 25 kW dish concentrated device, new attempt has been made for the part of the structure of the dish concentrated device, which including the mirror unit use the aluminum honeycomb panel substrate, the elevation angle institution use the underneath type and the installation of the mirror unit use the laser positioning. Develop the water-cooled disc receive target, making test for the focal spot on the focal plane based on sun tracking status and validate the effectiveness of the mirror units installation and the sun tacking. Equipped with the S260 Stirling electric generation system, and the working running shows that there is a basic linear relationship between the DS-CSP net power output and the solar direct normal irradiation （DN1） , the maximum value of the DNI is 761 W/m^2 and the DS-CSP net power output reach to 40.5 kW, and the conversion efficiency is 26.6%.
