| 摘要: |
| 变电站故障会导致供电区内的配电网瘫痪，造成大面积失电。为此，提出一种考虑快速可拆卸变压器的变电站-配电网协同故障恢复方法。构建快速可拆卸变压器应用下的故障恢复框架，阐明变电站变压器的恢复机理；提出“运输 — 维修”二阶段恢复策略，涵盖快速可拆卸变压器、线路、小型配电变压器3类故障；计及网络重构，建立变电站-配电网故障恢复优化模型，利用广义Benders分解算法进行求解。基于改进的141节点配电网算例进行仿真，验证所提方法的有效性。仿真结果表明，所提方法能够有效缩短变电站-配电网系统故障恢复时间，提高负荷恢复率，且具有更高的求解效率。 |

| Abstract: |
| The substation fault will lead to the paralysis of distribution network within the supply area, resulting in widespread power outage. Therefore, a substation-distribution network cooperative fault recovery method considering quickly-detachable transformer is proposed. A fault recovery framework under the application of quickly-detachable transformer is constructed, the recovery mechanism of transformer in the substation is elucidated. A “transport-repair” two-stage recovery strategy is proposed, which covers three types of faults of quickly-detachable transformer faults, line faults, and small distribution transformer faults. Conside-ring the network reconfiguration, an optimization model for substation-distribution network fault recovery is established, and the generalized Benders decomposition algorithm is used for solution. The simulation is carried out based on a modified 141-node distribution network example to validate the effectiveness of the proposed method. The simulative results show that the proposed method can effectively shorten the fault recovery time of substation-distribution network system, improve the load recovery rate, and has higher solving efficiency. |
