Research And Design Of Solar Photovoltaic Grid-connected System For Ground Traffic Center Daylighting,Band In Capital International Airport

As the fossil energy disappearing and the burning of fossil energy caused great damage to the environment,development of renewable energy has been paid the world’s attention.Photovoltaic power generation,as one of the renewable energy utilization ways,with its characteristics such as wide distribution,clean pollution-free,infinite energy,becomes an ideal replacement of traditional fossil energy sources.In the form of the use of photovoltaic power generation,due to building integrated photovoltaic can realize the power of the spontaneous for private use in order to solve the energy consumption problem of the city,building integrated photovoltaic becomes the focus of current research.In this paper,research and design of photovoltaic power generation system in Capital International Airport is taken into account,by making full use of existing conditions achieves the integration of solar photovoltaic into building design at the airport.The subject has important practical significance and engineering application value.Firstly,the meaning of photovoltaic power generation system that is configured in the airport and background are introduced in the article.The installation of photovoltaic power generation system in airport at home and abroad research status are reviewed from two aspects of the use of form and location scheme,system design and network technology and design proposals on airport photovoltaic system are given.Then,related to photovoltaic battery array of photovoltaic power generation systems technology,composition and operation principle of the photovoltaic power generation system,grid type photovoltaic power generation systems are summarized and the principle of inverter for photovoltaic power generation is discussed.Meanwhile,mainpoints of design and technology in photovoltaic grid system are summed up,including site solar energy resources,battery array layout,main equipment selection,photovoltaic power station,and connected to the electricity grid.According to the main technical points given by the situation,on the basis of electricity consumption statistics of Capital internationalAirport and solar energy resources analysis,the reasonable location scheme is determined and Ground Traffic Center daylighting design of Capital International Airport with photovoltaic grid system are designed and the photovoltaic grid electrical primary system and secondary system are completed.At last,a scientific and reasonable calculation method is adopted for the design of photovoltaic grid generation system to estimate the generation power and calculate the generation benefit and the economic benefit and energy conservation and emissions reduction benefit of the designed plant are assessed.Building photovoltaic grid-connected power generation system in the airport is a new direction in current application of photovoltaic and has the characteristics of some different from conventional photovoltaic power station.We hope that the research results in the article can provide some advantageous experiences for the application of PV system in the airport.
