The invention discloses a graph theory-based traction substation group cut-through power supply system reliability analysis method. Firstly, the reliability of electrical elements in a traction substation group cut-through power supply system is evaluated; secondly, topologizing the physical structure node-branch of the traction substation group through power supply system, and assigning the reliability to the corresponding node-branch; and finally, the reliability of the power supply area is calculated and determined, and reliability grades are divided. The method has the advantages that the physical structure of the complex traction substation group cut-through power supply system is topologized through the nodes and the branches, the reliability level of the traction substation group cut-through power supply system is evaluated in real time, and the method is simple and efficient.
本发明公开了一种基于图论的牵引变电所组群贯通供电系统可靠性分析方法。首先,评估牵引变电所组群贯通供电系统中电气元件可靠度;然后,将牵引变电所组群贯通供电系统物理结构节点‑支路拓扑化,并对相应节点‑支路进行可靠度赋值;最后,计算确定供电区域的可靠度,并划分可靠性等级。本发明的有益效果是:使用节点和支路将复杂的牵引变电所组群贯通供电系统的物理结构拓扑化,实时评估牵引变电所组群贯通供电系统的可靠性等级,方法简洁高效。
