| 摘要: |
| 我国偏远欠发达地区仍存在部分全盲电缆配电网,其历史数据丢失且缺乏监测设备,无法实现拓扑管控。为此,提出一种基于边缘扰动分析的全盲电缆配电网广义拓扑恢复方法,不同于传统拓扑辨识,该方法在无内部监测及历史数据下,实现全盲网络拓扑结构、分支长度与分支截面的“一次性”完备恢复。该方法通过捕捉全盲电缆配电网络边缘节点的自然暂态扰动响应,利用扰动传播分析提取扰动共有传播路径长度,基于边缘节点间共有传播路径长度的相关性分析恢复拓扑结构;进一步结合边缘扰动响应波形的内部畸变点分析计算各分支长度,并依据配电网分支规律,实现分支截面的逐步提取。真实10 kV配电网的测试表明,该方法能有效实现广义拓扑的恢复,其灵敏度分析验证了关键参数的影响范围。 |

| Abstract: |
| In China’s remote underdeveloped regions, some fully blind cable distribution networks still exist where historical data is lost and there is a lack of monitoring devices, so it is impossible to achieve topology management and control. Aiming at this problem, an edge-disturbance-analysis-based generalized topology recovery method for fully blind cable distribution network is proposed. Unlike conventional topology identification, this method achieves one-time comprehensive recovery of topological structure, branch length and cross-section of the blind cable distribution network without internal monitoring or historical data. The approach captures the natural transient disturbance responses of the edge nodes, extracts common propagation paths of disturbances by using disturbance propagation analysis, and reconstructs topology by correlating shared propagation paths between edge nodes. Furthermore, the length of each branch is calculated by analyzing the internal distortion points in the edge disturbance response waveforms and determines branch cross-sections progressively according to the distribution network branching patterns. Actual 10 kV distribution network tests demonstrate effective generalized topology recovery, and its sensitivity analysis verifies the influence range of key parameters. |
