    摘要:

    光热发电技术是太阳能利用的重要手段之一,其中,塔式光热发电技术因其大规模储能等优势,具有较好的应用前景。定日镜作为塔式光热电站的重要单元,其抗风安全性直接影响电站的正常运行。从结构体系、风荷载、风致响应与振动控制等方面对定日镜结构抗风设计中的关键问题进行文献综述,得到以下结论:定日镜主要采用“大尺寸反射镜+框式镜架+独立柱式基座”的结构形式;风荷载模拟中存在定日镜的尾迹区湍流分析困难、镜体峰值荷载难以预测及缺乏实测值验证等问题;风致响应受来流风湍流强度、定日镜工作角度及镜场布置等因素影响较大;风致振动控制可通过挡风墙物理隔离、调整定日镜结构形式以及采用减振器控制等技术手段实现。然而,镜群风干扰效应、来流风—定日镜结构流固耦合及微振控制技术等研究有待进一步开展,以期为提高定日镜结构的抗风安全性提供技术依据。

    Abstract:

    Solar thermal energy technology is one of the important means of solar energy utilisation, among which tower solar thermal energy technology has advantages such as large-scale energy storage and has good application prospects. As an important unit of a tower solar thermal power plant, the wind safety of the heliostat directly affects the normal operation of the plant. This paper presents a literature review of the key issues in the wind resistance design of heliostats in terms of structural system, wind loads, wind induced response and vibration control, etc. The following conclusions are obtained: Heliostats mainly adopt the structural form of “large size reflector + frame mirror frame + monopole base”; The wind load simulation has problems such as difficulties in analyzing the turbulence in the wake of the heliostat, difficulty in predicting the peak load of the mirror and lack of verification of the measured values; Wind-induced response is strongly influenced by the turbulence intensity of the incoming wind, the working angle of the mirror and the layout of the mirror field, etc. ; Wind vibration control can be achieved by the physical isolation of the wind barrier, adjustment of the mirror structure and the use of vibration damper control. However, further research is needed on the effects of wind disturbance in mirror groups, fluid-structure coupling of incoming wind and mirror structures and micro-vibration control techniques, in order to provide a technical basis for improving the safety of mirror structures against wind.
