Abstract
In recent years,with the global energy shortage and environmental deterioration,the development of new energy has become an important part of the national energy structure reform.As a clean and reliable new energy,the construction and operation of solar power stations have attracted much attention.Based on the background of a domestic Kengtang surface photovoltaic power station,this paper focuses on the structural scheme,modeling and design method,structural component selection and cost composition of a flexible support for photovoltaic power station.The results show that the flexible support structure scheme can meet the requirements of long span in east-west direction and north-south direction,especially the span in east-west direction is more than 40 m.The support structure mainly includes load-bearing cable structure,middle beam structure,side beam structure,cable-stayed anchorage structure,triangular brace,foundation structure,etc;the selection of structural section can meet the requirements of structural strength,stiffness and stability;moreover,for large-scale application scenarios with flat landform,considering all the civil construction costs,the economy of flexible support photovoltaic power station is slightly higher than that of fixed support.This paper will further consider the additional values such as land use efficiency and land compound use value of flexible support,the economy of flexible support photovoltaic power station will be significantly higher than that of fixed support.关键词
