| 摘要: |
| 在调度员培训系统DTS(Dispatcher Training System)中提出了一种快速实用的形成网络拓扑与局部修正的方法。在网络拓扑形成中采用两步分析策略：第一步归并物理结点，第二步形成关联电气岛。将离线数据组织成物理结点一元件关联分层链表结构。开关动作引起网络拓扑的变化可在此结构上采用局部的广度优先局部搜索，进行网络拓扑的快速修正，搜索范围不超过动作开关所在的电压等级。通过局部搜索后可以直接修正导纳矩阵。该方法不受接线方式和初始条件的影响。 |

| Abstract: |
| An applicable method of fast network topology generation and partial modification forDTS(Dispatcher Training System) is presented. Two-step scheme is adopted for network topology generation:uniting physical nodes and forming electrical island. A hierarchical physical node-element chain structure is formed with off-line data,based on which,the topological change caused by switch operation can be partially modified quickly using breadth-first search. Its search range is within the voltage grade of the operated switch. By local search,the admittance matrix is directly modified. The proposed method is independent of wiring pattern and initial conditions. |
