摘要
以陕西省气象数据、卫星遥感数据、地理数据等为数据源,采用Delphi开发语言,以基于COM组件技术的ArcEngine作为底层开发平台,使用基于构件的方法研制了陕西省太阳能资源评估业务系统。该系统包括辐射数据管理、辐射资源计算、太阳能资源评估和产品制作等四部分模块,其中辐射资源计算主要包含水平面和山地太阳总辐射分布式计算两种模型,是本系统的核心模块。该系统可提供陕西省不同时间尺度上太阳总辐射、直接辐射、散射辐射等的水平面和山地辐射模拟值,并可完成对全省太阳能资源丰富程度、稳定程度、资源储量等指标的评估,实现了太阳能业务工作的系统化,有效地解决了目前太阳能资源计算和评估中存在的问题。
Meteorological data,satellite remote sensing data,and geographic data have been the primary data sources.The Delphi program language was adopted and the ArcEngine based on the COM groupware technique was taken as the bottom development platform to develop an operational system for solar energy assessment in Shaanxi Province in this work.The operational system is comprised by four modules,i.e.,solar radiation data management module,solar energy calculation module,solar energy assessment module,and production module.Solar radiation horizontal and distributed models over mountainous terrains are the core components in the solar energy calculation module of the system.The operational system can run in operating systems of WindowsNT/2000/XP,and has better compatibility,portability,friendly user interface,and powerful functions.It can also read,write,display,and search for solar radiation data,accurately calculate and evaluate solar energy over horizontal and mountainous terrains at different time scales.It provides the following advantages.First,solar radiation data from meteorological stations and radiation monitoring stations can be stored into the database,which can be read,written,and managed in real time.Then the data will be called and displayed by client,finally achieving integrative management for spatial and vector data.Second,the operational system can calculate solar energy over horizontal and mountainous terrains at varying time scales.Results can be added up and performed statistical analysis in regional units,and also be evaluated in richness,stability, reserves,availability,and utility value,and finally be displayed in a raster image or data sheet.All the geographic information can display overlay,making full use of the advantages of GIS.In summary,the operational system can effectively solve problems associated with solar energy calculation and assessment,improving solar energy operation.In the meanwhile,the social service ability of the operational system will be further developed corresponding to lar
