摘　　要：针对某城市配电网故障定位自动化程度低、各系统数据利用不足等情况,从数据融合的角度出发,通过内部专网将配电网调度管理系统、SCADA系统、融合终端及用采系统等系统数据进行融合,开发基于多维信息融合的配电网故障研判系统。该系统可分为前台操作界面和后台服务器两部分,前台操作界面基于Visual C++6.0开发环境,将各功能部分模块化;后台服务器由基于Java Web技术进行开发的数据库系统实现。该系统操作方便、运行可靠、适用性强且扩展性好,能实现配电网故障定位、隔离和配电网络重构,方便在全省范围内推广,对配电自动化的发展具有实际工程意义。目前已在某地区试运行,效果良好。Based on the perspective of data fusion,in response to the low level of automation in fault localization in a certain city's power distribution network and underutilization of data from various systems,a multidimensional information fusion⁃based power distribution network fault diagnosis system is developed.It is achieved by integrating system data from the distribution network dispatch management system,SCADA system,fusion terminals,and data acquisition systems via an internal private network.The system can be divided into two parts:the front⁃end user interface and the back⁃end server.The front⁃end user interface is developed using the Visual C++6.0 development environment and modularizes different functional components.The back⁃end server is implemented using a database system developed based on Java Web technology.The system is user⁃friendly,reliable in operation,highly adaptable,and exhibits good scalability.It enables fault localization,isolation,and reconstruction in power distribution networks.It is convenient for province⁃wide promotion and holds practical engineering significance for the development of power distribution automation.The system has been undergoing trial operation in a specific region,and the results have been positive.
