Research And Design Of BIPV Project In Ningxia Area

With the decrease of primary energy and the continuous breakthrough of new energy generation technology,a large number of photovoltaic power generation projects have been set up in Ningxia area of China to alleviate the energy dilemma.But the excessive construction of large-scale centralized photovoltaic power stations is gradually exposed to malpractice.While the Building Integrated PV technology(BIPV for short)which is the effective combination of new energy generation equipment and urban architecture,makes a new mode of photovoltaic power generation for urban buildings come true and indicates a new direction for distributed photovoltaic technology of cities.Ningxia is located in the northwest of China,where solar energy is rich.Its local climate and urban power grid environment meet the requirements of building BIPV project.Take the design of the Wanda Plaza PV project in Wuzhong as main,this paper focuses on the design of the electrical scheme for the BIPV project and discusses the key technologies of access to the distribution network for PV.It studies the following in-depth research in this field.1)Analysis of solar energy resources and development prospect in Ningxia area.According to the meteorological data,this paper analyzes the climate characteristics and the abundance of solar energy resources in Ningxia area.It studies the current situation and existing problems of solar energy resources development in Ningxia at the same time.On this basis,the feasibility and necessity of further development about solar energy resources are deeply discussed,and the significance of building BIPV project in this area is clearly defined.2)The overall design of Wuzhong BIPV project.The BIPV technology includes the content and realization form of BIPV technology,the application practice and application prospect of BIPV technology.Through its research,this paper introduces the civil foundation,construction conditions,system composition and equipment layout of the BIPV project in Wuzhong City,and designs it.Finally,the overall layout of the system is determined.3)The design of photovoltaic power source part for BIPV Wuzhong project.Firstly,this paper introduces the principles of photovoltaic generation,output characteristics of photovoltaic panels and photovoltaic control technology.On the premise of this,the power supply is designed in detail,which includes the selection of photovoltaic power components,the installation angle of the photovoltaic components and the series scheme of photovoltaic components,according to the construction practice.4)Scheme design of grid connected operation for Wuzhong BIPV project.This paper designs the grid connected photovoltaic system,which includes the selection of grid connected equipment,such as the selection of inverter,the introduction of confluence equipment,and the planning of the two monitoring system.And further study for the grid connected operation mode of the PV system,the network access mode and the selection of network point is made to complete design of grid connected structure for this project.In order to make full use of local solar energy resources to generate electricity in Wuzhong Wanda Plaza BIPV project and ensure its reliability and economy when connected to micro grid,this paper mainly focused on equipment selection,structure layout,and the design of access mode and access points.This design will become the prototype of the project in the future,and it will provide valuable experience for the design and construction of other distributed photovoltaic projects.
