电力系统继电保护图形数据一体化的研究

为满足现代电力系统继电保护图纸信息管理的需求，提出以模块为单位的继电保护图纸加工与图形数据一体化的设计方法，将继电保护图形与数据基于模块地集成并存人数据库。用此方法对某变电站的继电保护图纸进行加工并有效地提取数据后，可满足继电保护图纸浏览、元件信息查询与修改等多种功能的需求。

Study on the graph-datum integration for the relay protection of power system

The method of drawing machining and the modularization design of graph-datum integration for relay protection are presented, the module-based graphs and data are integrated, and are stored in corresponding database, to meet the requirements of graph-information management of relay protection of modern power system. The various functions such as drawings' browsing, information searching and modifying etc. can come true by the use of the technique to machining relay protection drawings of a substation and to fetch data efficiently through application program.
