可视化供电系统检修计划的数据库组织方法

根据供电系统设备、接线特点，建立基本属性库，依据调度操作习惯，确定设备、接线图形的映射大系。基本属性库记录供电系统中包含所有器件的基本特征，如设备名称、电压等级、图形等：映射关系包括变电站内接线和站点间连按关系等。利用动态特征表，表示供电系统中开关器件的动作状态、网络拓扑的变化情况。通过映射法则，将基木属性库、映射关系库和动态特征表联系起来，构成符合供电系统动态操作的可视化数据库。同时，给出映射查询方案。

Database Organization of Visualized Scheduled Maintenance for Power Supply System

Basic property database was established according to characteristics of power supply system devices and their connections. The reflection between device and figure was - determined by conventional power dispatch procedures. The whole basic feature of devices, such as name of device, voltage level and figure, was recorded in database. Connections of inside and outside of substation were covered by reflection functions. Switch-state was recorded in dynamic characteristic table. Basic property database, reflection relation database and dynamic characteristics table were connected by reflection principles. The reflection query method was also given.
