论文摘要
我们提出了一种仅使用电压测量值的不平衡三相径向网络中联合相识别和拓扑恢复的方法。通过共同恢复相位和拓扑，我们利用所有三个相电压测量值，并可以处理某些总线具有三个阶段的网络。理论上，我们的方法是通过一种新颖的三相功率流的线性化公式来证明的，并在线阻抗和负载统计统计中精确定义且合理的假设。我们验证了在Opendss中现实条件下模拟的三个IEEE测试网络上的方法，将我们的性能与最新状态进行了比较。除了提供一种新的阶段和拓扑恢复方法外，我们的直觉结构化线性化模型还将为在此应用程序和其他应用程序中的未来工作提供基础。
We present a method for joint phase identification and topology recovery in unbalanced three phase radial networks using only voltage measurements. By recovering phases and topology jointly, we utilize all three phase voltage measurements and can handle networks where some buses have a subset of three phases. Our method is theoretically justified by a novel linearized formulation of unbalanced three phase power flow and makes precisely defined and reasonable assumptions on line impedances and load statistics. We validate our method on three IEEE test networks simulated under realistic conditions in OpenDSS, comparing our performance to the state of the art. In addition to providing a new method for phase and topology recovery, our intuitively structured linearized model will provide a foundation for future work in this and other applications.
