The Research And Implementation Of The Visualized Management System For Photovoltaic Power Station

With the rapid development of our country’s economy and society,people pay more and more attention to the problem of environmental pollution and the shortage of energy.China has invested a large amount of funds to the energy sources to gradually replace the traditional high pollution energy.In recent years,China has gradually developed and utilized clean energy,such as biomass energy,wind energy,solar energy and marine energy.In particular,solar energy is rich,clean,easy to collect and so on.It has gradually become one of the most important power sources.At present,China has become the fastest growing country in the global PV installation.The demand for direct and efficient management of the national photovoltaic power plant are increasing.Based on the traditional two-dimensional data information management platform has been unable to meet the people’s requirements of multi type,multi scale,multi dimension and massive spatial information.The research and application of 3D visualization service is around the corner.This thesis is based on the construction of photovoltaic power plant visualization analysis and display platform and combined with the related technologies of osgEarth,MFC.This system uses VS2010 as the development platform to design and implement a visualization analysis and display system of photovoltaic power station based on MFC.The main functions are as follows:First,it has realized the visualization of the solar radiation distribution in various provinces and cities of china.According to the light radiation statistics of each month in the past 55 years,the system realizes that different light radiation display different colar on the earth and realizes the interactive function between osgEarth and MFC.By clicking drop-down menu to achieve the display of distribution in different years.Secondly,the visual function of the national photovoltaic power station is realized.The system has stored the data of the main built photovoltaic power stations in the database and realized the distribution visualization of the main PV power stations in China.The system has also been implemented the function of the fixed-point path roaming and adding,deleting,modifying,querying and other functions for the PV power station data.Finally,the location function of the photovoltaic power station is realized.This system combines the analytic hierarchy process and the fuzzy comprehensive evaluation method to realize the location of the photovoltaic power station.It makes comprehensive evaluation of sunshine resources,electricity consumption,power grid conditions,meteorological terrain and land use properties,and then uses visualization technology to mark areas suitable for building photovoltaic power stations.The results of the system are clear and intuitive,which can provide the decision basis for the management of the photovoltaic power station and the location of the photovoltaic power station.
