GIS与配网自动化系统图模交互实践研究
Practical Research on Graph and Model Exchange Between GIS and Distribution Automation System
-
摘要:
目前新建配网主站的供电局，大部分未能实现地理信息系统(GIS)图模的自动导出及自动导入到配网自动化系统。数据模型的GIS导出到配网自动化系统的导入过程中，普遍存在数据质量问题。SVG图形导入配网自动化系统之后普遍出现图元不统一，图形错位等现象。广东电网各地区已讨论确定图模交互工作流程，并明确相应工作责任部门及负责人，但在工作流程固化和自动化介入方面还有待进一步加强。分析了GIS系统中的模型问题，及图形导入到配网自动化系统后的存在问题，给出了相应的建议对策。研究表明：结合GIS与配网自动化系统图模交互实践和管理流程的优化，可有效提升企业级应用的集成效果。 Abstract:At present, the graphics modules' automatic export from geographic information system(GIS) and import to distribution automation systems (DAS)are not solved in most of the new local power supply bureaus. Data quality is the most common problem found in the data model between the export from GIS and the import to DAS. The graph and model exchange cannot be finished in an automatic manner while DAS does not have unified graphic primitives and the graphics appears to be misplaced after importing SVG graphics from GIS. Workflows for graph and model exchange between GIS and DAS have been discussed and established in many power supply bureaus of Guangdong Power Grid. Provided that the correspondent department and personel have been assigned, the process still needs to be strengthened and so does the automation level. This paper presents the problem of model in GIS and graphics after deriving from GIS and importing to DAS. Suggestions and the corresponding countermeasures are also provided . The results show that the enterprise application integration will be further improved by considering the practical research on graph and model exchange between GIS and DAS with the optimization of management process.
