光伏电站支架系统结构抗台风设计实践

  目的]  广东沿海太阳辐照资源丰富，为了利用好光资源，开发建设光伏电站，就必须研究光伏电站的重要结构物——光伏组件支架系统的抗台风设计。支架系统的设计参数选择对于工程的安全性、经济性均影响非常大。  方法]  将以广东沿海某光伏电站为例，从台风荷载参数取值，结构体型系数，构造措施等方面，结合有限元软件数值模拟及台风灾害后评估，介绍光伏电站支架系统结构抗台风设计的要点及实践经验。  结果]  项目建成后，先后经历了“天鸽”（17级）、“山竹”（14级）台风正面吹袭考验，在经历台风后，整个光伏区阵列受损较小。  结论]  项目建成后，遭遇几次超过12级以上的台风正面吹袭，并未造成严重损失，支架系统结构设计是比较成功的，设计理念和方法得到了印证，可为实际应用提供指导。

Design and Practice of Typhoon Resistance for Supporting Bracket System of PV Power Station

  Introduction]  There are abundant solar irradiation resources in Guangdong coastal areas. In order to make good use of the light resources, we need to develop and build photovoltaic power stations in these areas, so it is important and necessary to study the typhoon resistance design of photovoltaic supporting bracket system, which is an important structure of photovoltaic power stations.The design parameters of the supporting system have a great influence on the safety and economy of the project.  Method]  Taking a photovoltaic power station along Guangdong coast as an example, this paper introduced the key points and practical experience of typhoon resistance design of the supporting system of photovoltaic power station from the aspects of typhoon load parameters,structural shape coefficient and structural measures, combined with numerical simulation of finite element software and post-typhoon disaster assessment.  Result]  After the completion of the project, it experiences the test of typhoon "Hato" (Level 17) and"Mangosteen" (Level 14) . After the typhoon, the whole photovoltaic array suffers less damage.  Conclusion]  After the completion of the project, several typhoons above grade 12 hit the front of the project, which does not cause serious losses. The structural design of the bracket system is relatively successful, and the design concept and method are confirmed, which can provide guidance for practical application.
