Research And Design Of Agricultural BIPV Project In Hanyin County

Building integrated photovoltaic(BIPV)is a method of combining solar power generation technology in buildings.More and more countries attach importance to the development of this green power generation technology.The installed capacity of Germany,Japan and India is increasing year by year,and China is also expanding year by year.The combination of photovoltaic technology and agricultural greenhouse is an application innovation of BIPV technology,which has been more and more widely promoted.With the continuous development in the field of agriculture,the new concept of "photovoltaic+" is put forward.Firstly,this paper studies the overall address conditions,geological conditions,regional solar energy resources and solar radiation of the area where the project site is located,and concludes that the location fully meets the construction requirements of BIPV project.Secondly,the structure of photovoltaic agricultural greenhouse and the types of photovoltaic modules are introduced,and a single building front slope glass double glass crystal silicon transparent greenhouse is designed.Then,the selection of photovoltaic power generation module is carried out,the type of photovoltaic operation array is determined,the operation mode of photovoltaic array is designed and calculated,and the power on grid is estimated.Finally,the grid connected power generation system is designed,reactive compensation is calculated,the main electrical wiring and primary equipment are designed and selected,and the lightning protection and grounding over undervoltage protection are designed.The control system of power station operation,including photovoltaic power generation integrated monitoring system and communication system,is designed to realize the automatic protection,operation monitoring and control of the primary and secondary electrical measurement facilities Signal acquisition,measurement,remote control and other functions.
