摘要
网络流理论是拓扑几何中的重要理论之一。将电力网按照网络流分析方法的需要进行拓扑,在明确点与边所对应的设备之后,可以跨越电压等级,构建覆盖全网设备的点-边集合。在此集合上可以对供电树的结构、网络电流进行方便的分析,逻辑简单、清晰,易编成计算机语言,且受网络参数维护和数据采集影响较小。可系统性地解决目前调度自动化系统高级分析功能使用不理想的问题。
Network flow theory is one of the most important theories in topological geometry. On the premise of correct definition, the power net can be described a pure point-line assemblage, containing all devices and across the voltage. The structure of the power tree and calculate the current can be analyzed in the net through this assemblage by the computer. The method is simple in logic and lucid in thought, and more less influenced by the parameter maintenance. The problem can be solved that use inconveniently for advanced application function in the automation system by the network flow analysis method.
