研究了电力系统的拓扑分析问题。电网图上元件之间的连接关系、带电着色、支路类型的判别、无阻抗元件的融合及节点编号等是能量管理系统(EMS)高级分析的基础,同时有利于系统调度员对系统的决策和判断。在图形建模的基础上,提出了一个利用深度优先搜索(DFS)实现电力系统拓扑分析的新方法,能在1次遍历后,实现带电着色、支路类型识别、节点编号及子网编号,相对于其他算法该算法效率较高。
Studied the topological analysis of power system. The connections between the elements on the grid map, the charging coloring, the judging of the branch type, the integration of non-impedance components and the node number are the bases for the advanced analysis of the energy management system (EMS), and help the system dispatcher to make decisions on the system And judge. Based on the graph modeling, a new method of power system topology analysis using depth-first search (DFS) is proposed. After one pass, the method achieves the functions of charged shading, branch type identification, node number and subnet number, The algorithm is more efficient than other algorithms.
