采用光线追迹法,建立矩形阵列布置下碟式光热太阳能电站聚光器任意时刻空间状态数学模型和聚光器利用率动态模型,通过算例验证模型的正确性,分析阵列中任意聚光器不同时刻的采光遮挡特性,探讨布置参数对聚光器利用率的影响。结果表明:电站阵列布置夹角和布置间距是影响聚光器利用率的主要因素,布置夹角的取值对聚光器利用率影响显著,增大布置间距只能在一定程度上提高聚光器的利用率,且利用率随间距的进一步增大其效果趋于不明显。
The ray tracing method was used to establish the mathematical model of the spatial state of the collector and the dynamic model of the condenser utilization under the rectangular array arrangement, and the correctness of the model was verified by an example to analyze any spotlight in the array Lighting at different times of the light blocking characteristics of the layout parameters to explore the impact of condenser utilization. The results show that the angle and arrangement pitch of power plant array are the main factors affecting the utilization of condenser. The value of arrangement angle has a significant impact on the utilization of condenser. Increasing the arrangement pitch can only increase the concentration of condenser The utilization of the device, and the utilization rate tends to increase with the spacing tends to be less obvious.
