| 摘要: |
| 配电网电源侧故障下大范围负荷转移优化策略及实现方法是馈线自动化的延伸，对提高配电网供电可靠性具有重要意义。首先定义了母线失压类型，进而把大范围停电问题分解为不同类型的母线失压问题。然后提出了不同类型母线失压的大范围负荷安全转移优化策略，再把母线失压的大范围负荷转移问题转化成了等效馈线故障恢复问题和站内负荷转移问题。最后提出了大范围负荷安全转移方案生成方法，给出了各个模块的实现框图。该研究为配电网电源侧故障大范围负荷转移走向实用化提供方法和技术支撑。 |

| Abstract: |
| The optimization strategy for wide range of load transfer and its implementation in distribution networks during power supply side failure is the extension of feeder automation. It will be of great significance to improve the reliability of distribution network. Firstly, the paper defines the types of busbar voltage loss. Thus the problem of large scope blackout is decomposed into different types of busbar voltage loss problems. After that the optimization strategy for wide range of load transfer of different types of busbar voltage loss is proposed, where the wide range of load transfer problem is transformed into the problems of fault recovery of equivalent feeders and load transfer within the substation. Finally, a scheme of a wide range of load transfer is investigated and the flowchart of each module is given. This research provides a method and technical support for the application of wide range of load transfer under busbar voltage loss in distribution networks. |
