| 摘 要： | 针对供电线路监控中,带电状态搜索传统算法占用内存大、耗时长、效率不高等问题,提出一种色流算法。通过分析单电源和双电源供电模式的供电线路结构特征,借鉴电流的流动,定义色流源、色流管、色流阀,推导供电线路及设备的带电状态搜索、分析判断与染色的算法,并将基于该算法的监控系统应用到了麻城—黄陂贯通线的运行状态监控中。实践表明,供电线路的状态监控利用色流算法,不再需要用电压和电流互感器提取电气信号,简化了监控装置,节省了投资成本。与传统的状态搜索算法相比,色流算法较简洁,搜索步骤少,占用计算机内存小,运行速度快,提高了监控效率。

| Abstract: | In order to solve the problems of large memory, long time consuming and low efficiency of traditional algorithm for searching live-line state inpower supply line monitoring and control, this paper proposed a color flow algorithm. The paper analyzed the structural characteristics of power supply lines of single power supply and dual power supply modes, defined color flow source, color flow tube and color flow valve by referring to the flow of electric current, deduced the algorithm of searching, analyzing, judging and coloring for the live-line state of power supply lines and equipment, and applied the monitoring and control system based on the algorithm to the operation state monitoring and control of Macheng—HuangpiRailway Power Transmission Line. The practice result shows that the state monitoring of the power supply line based on the color flow algorithm is no longer necessary to extract electrical signals with voltage and current transformers, which simplifies the monitoring and control device and saves the investment cost of the monitoring device. Compared with the traditional state search algorithm, the color flow algorithm is simpler, the search steps are less, the computer memory is small, and the running speed is fast, which improves the monitoring and control efficiency. |
