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.
