3、ustry in recent years, the photovoltaic power generation industry in China has ushered in a new stage of rapid development. Especially due to the approval of the project, the scale of the development of small-scale distr

4、ibuted photovoltaic power plants is getting larger and larger. More and more small and medium-sized factory roof construction of photovoltaic power plants. There are several typical characteristics of such photovoltaic p

5、ower plants: First, the photovoltaic power plant construction sites are factory roofs, and second, single-point access scale is generally not more than 6MW, third access is mostly 10kV lines or user distribution room acc

6、ess grid Fourth, the use of “spontaneous use, the remaining amount of Internet access“ or “full Internet access“ mode. In a small town with a fast economic growth, the construction of photovoltaic power plants with these

7、 characteristics is very common and has a bright future. This article aims to provide a typical design of a small business roofing PV power plant. The first chapter analyzes the solar energy resources where the project i

8、s located, the solar energy resources from China's solar energy resources to Shandong Province, and analyzes the solar energy resources at the project sites so as to judge that the project location is suitable for th

9、e construction of photovoltaic power stations. The second chapter starts from the system level, designs the networking mode of PV power station, accesses the scheme of the system, and then carries on the electrical calcu

10、lation to the system, and then determines the power measurement mode of the system, and puts forward the concrete requirements for the secondary protection of the system. Then detailed description of photovoltaic power p

11、lant telematics and communications systems. In the third chapter, after the solution of the system is given, the specific technical requirements of the specific equipment in the PV power station are also included, includ

12、ing the selection of PV modules, the selection of inverters and the arrangement of PV modules. The fourth chapter is the overall evaluation of photovoltaic power station. Firstly, it analyzes the energy efficiency of the

13、 PV power station to estimate the power consumption, then calculates the profit of the PV power plant according to the power generation capacity, evaluates the overall economic benefits by considering the investment cost

14、 and operating cost, and analyzes the emission reduction benefits of the PV power station. Finally, the article summarizes the design of the entire photovoltaic power station, and draws the typical significance of the ph
