摘要
配电网绘图工具软件作为线损理论计算软件的配电网数据库接口及图形平台,可有效地提高配电网基础数据录入和维护的效率。在分析配电网数据的基础上,全面介绍了配电网绘图工具软件的开发环境、设计思路、关键算法和主要功能。它是利用AutoCAD2002软件中的VBA语言二次开发而成的,通过线损理论计算软件数据库数据分析,菜单、工具栏、图元模块制作,以及配电网拓扑分析等三部分来自动生成配电网接线简图,其关键算法是对线路的重新拓扑和编号。该软件图形化录入和维护配电网数据,具有直观、使用方便等特点。
As the database interface and graphic platform of the theoretical calculation software for distribution network line losses, the distribution network plotting software can effectively quicken the entry and maintenance of basic distribution network data. With the analysis of distribution network data, a comprehensive description is made on the development environment, design concept, key algorithm and main functions of the software. It is secondarily developed using VBA language in AutoCAD 2002, and can automatically generate distribution network connection schematic in three steps including analysis of data in the database of line loss theoretical calculation software, making of menu, toolbar and primitive blocks, and distribution network topology analysis. Its key algorithm lies in the retopology and recoding for the lines. The software graphically enters and maintains distribution network data and is of visual and convenient capabilities.
