【摘要】 本文通过在开发继电保护运行与管理专家系统过程中对图形显示与管理系统的研究，提出了一种结合数据库技术来实现对电力系统一次接线图进行管理的方法。所实现的图形生成与管理系统不仅能通过数据库从局部网络上获取各种元件的实时状态信息，及时反映到显示图形上，而且运行人员可以从图形上直接查询和修改某元件的保护配置和定值。更多还原

【Abstract】 Based on the information stored in thedatabase, a graphic system which can automatically developsingle line diagrams of power systems is presented in thispaper. The graphic system is embedded in a practical expertsystem for protective relay operation and management ofHunan provincial power system. Real-time information ofthe power system is obtained from SCADA system and isautomatically displayed. The operation conditions and thesetting values of the protective relay in the power systemcan be inquired and modified with the diagram.更多还原
