摘　　要：图模库一体化工具作为发电厂继电保护整定计算系统的重要组成部分,用于建立计算模型。为了减少图形建模过程中的人工操作,实现建模-计算-输出的一键式全过程自动实现,设计开发了具有图元建模、发电厂典型设计模板建模、文字描述建模及外部图形识别建模四种图形建模方式的图模库一体化工具。在图元建模基础上,发电厂典型设计模板建模及文字描述建模方式分别实现了利用典型接线设计模板及文字描述建模的半自动建模;外部图形识别建模实现对于采用AutoCAD所绘图形的全自动建模,从而有效提高了继电保护整定系统的智能性及其工作效率。As an important component of the power plant relay protection setting calculation system,integration of graph,model and database tool（IGMD） is used to establish calculation models for the setting calculation system.In order to make the power plant relay protection setting calculation system more intelligent and realize modeling-caculating-outputing only by one key automatically,the IGMD is developed to implement primative modeling,typical power plant design template modeling,text description modeling and external pattern recognition modeling.Based on primative modeling,typical power plant design template modeling and text description modeling achieve semi automatic modeling by graphic templates and ideogram respectively;and based on the external graphic recognition method,the IGMD can recognize electrical circuit diagrams drawing by AutoCAD and establish calculation models supermatically.The IGMD reduces manual operation and improves the efficiency for the power plant relay protection setting calculation system.
