【摘要】 针对智能变电站二次检修工作安全措施的可靠性和编制效率制约了智能电网安全发展的问题,提出一种应用SQLite嵌入式数据库辅助生成智能变电站二次安全措施的方法。分析了智能变电站二次安全措施的特点和SQLite数据库的体系结构,建立嵌入式数据库到逻辑数据库映射。通过建立SCD文件中装置、压板和回路特征数据与保护逻辑的索引对应关系,并根据典型设计库分析检修工作保护功能及功能回路的隔离范围,最终自动生成完整的二次检修工作安全措施,并可进行图形化展示。更多还原

【Abstract】 The problems that the reliability of the secondary maintenance safety measures in the intelligent substation and compiling efficiency restrict the safe development of smart grid. So the method which is applying SQLite embedded database to generate the secondary safety measures of the intelligent substation is put forward. The characteristics of the secondary safety measures of the intelligent substation and the architecture of the SQLite database are analyzed,and this paper maps the embedded database to the logical database. The correspondences between the device,the pressure plate and the circuit characteristic data have been established. And the protection logic index in the SCD file,the maintenance protection function and the isolation range of the functional circuit are analyzed according to the typical design library. The complete secondary maintenance safety measures are finally generated and graphical display can been shown.更多还原
