摘要

定日镜的结构和形状必须提供在多种工作条件下精确反射太阳辐射到目标上所需的刚度。因此，本研究的目的是研究在保持相同定日镜面积的情况下，不同矩形定日镜形状宽高比ε =L/W对螺旋布局性能的影响。这里的“L”和“W”分别是定日镜矩形的长度和宽度。基于矢量几何设计了不同定日镜模型，量化了定日镜宽高比变化对定日镜场布局效率的影响。结果表明，定日镜宽高比的不同取值对定日镜的视场效率有重要影响。

THE EFFECT OF RECTANGULAR HELIOSTAT SHAPE RATIO ON THE SPIRAL LAYOUT PERFORMANCE OF A SOLAR TOWER THERMAL POWER PLANT

The heliostat structure and shape must deliver the essential rigidity to accurately reflect solar radiation onto the target under several working conditions. Therefore, the aim of this study is to investigate the effect of various rectangular heliostat shape aspect ratios ε =L/W on the spiral layout performance considered by keeping the same heliostat area. Here ‘L’ and ‘W’ are the length and width of the rectangular heliostat shape respectively. An-inhouse computer programme is developed based on the vector geometry to design different heliostat models that can quantify the effect of the introduced aspect ratio changes on the efficiency of the spiral heliostat field layout. Results are presented and showed that the field efficiency can importantly affected when using different values for this heliostat aspect ratio.
