Design And Research Of Distributed Photovoltaic Power Generation Building Integration

In today's society,due to the large consumption of fossil fuels led to the energy crisis,environmental pollution,greenhouse effect and a series of social problems.People are eager to find a renewable energy to replace the traditional fossil energy.Solar energy due to clean environmental protection,rich resources,easy access and other excellent features have been people's attention.In recent years,China's government in order to achieve low-carbon goals,increased support and subsidies,China's rapid development of photovoltaic industry.PV building integration is a new combination of photovoltaic technology and architecture,photovoltaic technology is an important form of application.Externally pressurized gas bearing has been widely used in the field of aviation,semiconductor,weave,and measurementapparatus because of its advantage of high accuracy,little friction,low heat distortion,long life-span,and no pollution.In this thesis,based on the domestic and overseas researching.This paper first introduces the advantages and characteristics of photovoltaic building integration and the research background,purpose,content and significance of this paper.Then,the second chapter is divided into two parts: the first part is the disclosure of the principle of solar cells;the second part is its classification and contrast,reflecting the thin film battery and crystalline silicon solar cells in the superior.The third chapter analyzes the specific form of what,the design needs to pay attention to what many factors,and strive to pave the way for the design system.Chapter 4 of the trotters is how to design the system,divided into four parts.The first part is the design principles and steps,is the design guidelines;the second part is the introduction of the project profile;the third part of the project design before the analysis and planning;the fourth part is the Shenyang Kela Life Square,for example,the specific system Design introduction.In the design process,the main use of the tool is the photovoltaic system design software.The design uses Frist One's FS-392 cadmium telluride thin film battery,composed of a series number of 8,the parallel number of 5,an area of 28.8square meter photovoltaic array.And through the Power-One's PVI-4.2-OUTD-S-US inverter into the public bus into the grid.Through the design and simulation calculations,it is found that the total power generation capacity of the system is 2331500 k Wh in one year,which is equivalent to the emission of 230 tons of carbon dioxide into the air,which has high economic and environmental benefits.The last chapter is a summary of the previous summary and recommendations for the development of a photovoltaic building integrated system.
