| 摘要: |
| 分布式能源接入配电网后，传统的配电网断线定位方法面临着新的挑战。通过建立含分布式能源的配电网模型，分析发现含分布式能源的配电网，断线支路的不同节点会同时出现正功率和负功率(或零功率)特征，而非断线支路则为单一的功率方向，进而提出基于功率方向的配电网断线定位方法。介绍了配电网断线定位的功率方向原理，并基于MAS技术设计了具体的流程。实例分析结果证明了该方法的有效性。 |

| Abstract: |
| After the distributed energy access to the distribution network, the traditional distribution network disconnection and positioning method is facing new challenges. The distribution network model with distributed energy is established. And it is found that distributed nodes with disconnected branch have different positive and negative power (or zero power) characteristics, while the non-disconnection branch shares single power direction. In this paper, the power distribution method based on power direction is proposed. The power direction principle of the disconnection of the distribution network is introduced, and the specific process is designed based on MAS technology. The results of the example analysis show the effectiveness of the method. This work is supported by Science and Technology Protect of State Grid Shandong Electric Power Company (No. 520605170014). |
