提出了一种仅利用电压测量值的三相辐射状不对称网络的联合相位辨识和拓扑恢复方法。通过联合恢复相位和拓扑，我们利用所有三相电压测量，并可以处理网络中的一些总线有一个子集的三相。我们的方法是理论上合理的一种新的线性化配方的不平衡三相潮流，并作出精确定义和合理的假设线路阻抗和负载统计。我们验证了我们的方法在OpenDSS的现实条件下模拟的三个IEEE测试网络，比较我们的性能，以最先进的状态。除了提供一种新的相位和拓扑恢复方法，我们直观的结构化线性化模型将提供一个基础，为今后的工作在这个和其他应用。
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.
