中文摘要：

分析太阳辐射状况是光伏电站项目评估的重要举措，针对分析过程中涉及的各类数据计算和可视化查询，设计实现了省级太阳辐射模拟可视化查询平台。平台根据主要功能划分为数据处理子系统和查询分析子系统，数据处理子系统采用MODIS云量数据、气象站与辐射站历年数据，计算生成具有共同基准的多要素辐射相关数据；查询分析子系统将地图影像与实际数据结合显示，让数据模拟更直观、数据分析更合理。数据处理子系统使用了Qt进行开发，查询分析子系统使用ArcGIS Desktop、ArcGIS Server和MySQL数据库软件，结合Dojo、C#、ASP.NET MVC技术进行开发。使用Python作为“粘合剂”连接两个子系统，让数据成图和发布自动化。平台集数据处理和可视化查询为一体，能够以1 km×1 km的精度模拟分析出省级范围太阳辐射的分布情况，为光伏数据分析和光伏电站建设工作提供及时、有效、科学的技术支撑。

Abstract：

The analysis of solar radiation is an important basis for the evaluation of photovoltaic power station projects. Aiming at the calculation and visualization of various kinds of data in the analysis process, this paper designed and implemented the provincial solar radiation simulation visualization query platform. The platform is divided into data processing subsystem and query analysis subsystem according to main functions. Using MODIS cloud amounts data and historical data in weather stations and radiation stations, the data processing subsystem calculates multi-element radiation-related data with common standard. The query analysis subsystem combines map image with real data to make data simulating more intuitive and the analysis more reasonable. The data processing subsystem uses Qt as the development tool. Query analysis subsystem uses ArcGIS Desktop, ArcGIS Server and MySQL database software, combining with Dojo, C #, ASP.NET MVC technology to develop it. The platform uses Python as a “glue” to connect two subsystems to automate data processing and publishing. Platform combines data processing and data visualization, which can simulate and analyze the solar radiation at provincial level with an accuracy of 1 km×1 km, and provide timely, effective and scientific technical support for photovoltaic data analysis and photovoltaic power station construction.
