针对配电自动化图形平台中图元及其配置库间关联的测量点多，不仅配置繁杂，而且图形业务数据难处理的问题，提出了一种图库一体生成的图元实时编码及存显方法。在开源 OpenSCADA 监控平台基础上，通过配电自动化图元结构分析，给出典型变压器图元坐标系统的设计。以 Base64对配电网图元进行编码存储，利用 Java语言实现了配电网图元的动态操作的编码处理过程。以北京东站10 kV 配电网一个电气接线监控界面的生成为例，进行图库一体生成的编码存储和显示测试。结果表明：运用图库一体的图元编码技术设计监控系统图形界面，可简化监控图形系统处理过程，降低系统维护难度，使图元设计及其存储一次完成，具有重要的工程实用价值。%There are many measurement points in graphic elements and configuration library in the distribution automation graphic system, which are not only complex to configure, but also difficult to process the graphic data. To solve the problem, a method of primitive real time encoding and storage is put forward. Based on the monitoring platform of OpenSCADA, through the analysis of the primitive structure, a transformer element coordinate system is designed. Base64 encoding is used to storage the primitive, and Java is employed to implement the dynamic processing of the primitive. Taking the monitoring interface of 10 kV distribution network of Beijing East Railway Station as an example, this paper proceeds with a test on the encoding storage and display. The results show that designing graphical interface of monitoring system by primitive encoding of the graph-database integration can simplify the processing of the monitor graphics system, and decrease the difficulty of system maintenance, and accomplish the graphic element design and storage at a time, which has the important value for practical project.
