Abstract: With the rapid development of the economy,the shortage of electricity has become a key factor restricting regional development. In the Anhua area of Yiyang city,Hunan province,the rise of the dark tea industry has led to an increasing demand for power by tea factories. This paper takes the 200 MW PV power station in the Anhua area as an example,and based on the local solar resource conditions,a block power generation and centralized grid-connected structure plan for the PV power station is adopted according to the terrain,transportation,and land use types. The type of PV bracket is determined based on the initial investment cost of the PV power station,the reliability of the PV bracket,and the later maintenance factors,and the optimal installation angle of the PV modules is determined using PVsyst software. The spacing of front and back PV arrays and number in one PV string of PV modules are calculated through relevant theoretical calculations,and then the type of inverter is confirmed. The constructed PV power station is expected to provide an annual power generation of 18341 million kWh to the power grid,equivalent to saving 55200 t of standard coal. The project can significantly reduce the emission of atmospheric pollutants and has obvious social and environmental benefits.
