AbstractWith the rapid development of society today,people's demand for energy is alsoincreasing.With the gradual exhaustion of fossil energy,various new energy sources aregradually appearing in people's vision.As an important part of renewable energy,solar energyhas become one of the new energy sources with the most development potential due to itswide distribution,rich resources,and inexhaustible characteristics.With the development ofthe photovoltaic industry,photovoltaic power stations have also become diversified.With theunique geographical environment,weather and resources of Xining City,Qinghai Province,wind-solar hybrid power generation systems have emerged.Qinghai Province is asecond-class region with extremely rich solar and wind energy resources in the country,andthe wind and solar hybrid power generation system will become the leader in the new energysector in this region.This paper designs a 300KW wind-solar hybrid power generation system in ChengbeiMountain,Xining City,Qinghai Province.The main design ideas are as follows:First,thegeographical location,wind energy,climate,solar resources and other conditions of the areaare analyzed,and the feasibility of the project is explained.Secondly,the wind and solarhybrid photovoltaic power station is designed,including the selection of photovoltaic modules,the selection of wind turbines,the selection of electrical loads,the selection of batteries,theselection of DC lightning protection combiner boxes,and the selection of inverters.Detaileddesign instructions are provided for the series and parallel design of photovoltaic arrays,basicdesign of photovoltaic array brackets,system monitoring design,and system safety design.Third,analyze the overall situation of the system,including system benefits,environmentalbenefits,etc.In this design,this set of wind-solar complementary power generation system not onlymeets the normal daily electricity demand of farmers,but also reaches the peak in July andAugust every year in summer,bringing farmers a daily income of about 16,50 yuan.Finally,summarize the design of this article,and put forward further prospects.[Keywords]animal husbandry;wind-solar complementary;photovoltaic power station design;
