摘　　要：电力GIS与MIS的异构系统中存在的数据孤立问题一直难以得到有效解决,在电力GIS平台的基础上采用多源数据通信技术可实现各应用软件系统的数据共享。设计了GIS与MIS之间的应用接口模型。构建基于XML的数据交换平台,解决了跨平台的异构数据交换。提出了基于中间件技术与XML数据标准的多源数据通信策略,利用具有面向对象技术和组件式思想的中间件技术,通过可视化软件开发工具,将各系统的不同组件统一,最终形成多源数据通信平台。基于多源数据的理论线损计算和电网GIS专题图分析两个应用实例说明以上多源数据通信策略和算法的合理性。The problem of data isolation existed in heterogeneous systems has not been solved effectively all the time, especially between electric GIS and MIS. On the base of electric GIS platform, using multi-source data communications （MSDC） technology, data sharing between electric application programs can be realized. Application interface module between GIS and MIS is designed. Heterogeneous data exchange of different platforms is solved through constructing data exchange platform based on XML. MSDC strategy based on middleware technology and XML data standards is proposed. Using middleware technology with object-oriented technology and unit construction method, through visual software developing tools, unit constructions of different systems are unified. At last, MSDC platform is set up. Two examples about theory line losses calculation based on multi-source data and electrical GIS thematic maps analysis illustrate the rationality of technical scheme of MSDC and algorithm.
