轨道交通电力监控中的拓扑分析

Topological Analysis for Rail Transit Electricity Supervisory Control

在轨道交通电力监控中,根据车站对应电力主接线图上的设备图元和连接线颜色变化来实时监控整个车站内的带电情况。采用深度优先搜索算法,根据实时变化的电源电压和设备开断状态,动态地对电力主接线图进行网络拓扑分析并计算图中设备图元的带电情况。该方案在国内多条地铁线路的运营实践中均能够实时准确地完成拓扑着色功能。

In electricity monitoring of rail transit,real time monitoring the voltage presenting conditions in overall station according to the image elements of equipment and the color changes of the connecting lines on the electric power main wiring diagram of the station. By adopting depthfirst searching algorithm,in accordance with the real time voltage changes of power,and the ON /OFF states of the equipment,network topological analysis of the electric power main wiring diagram is conducted dynamically,and the voltage presenting conditions of image elements of equipment is calculated. The strategy has been practically applied in several domestic rail transit lines and accurately accomplishes topological coloring function in real time.
