Topology Analysis of Distribution Network based on Multi-Source Measurement Data

Aiming at the problem of poor real-time performance of the current distribution network network topology analysis, combined with the current situation where multiple measurement systems of the distribution network coexist. A method for network topology analysis of distribution network using multi-source measurement data is proposed. The distribution network Micro-synchronous Phasor Measurement Unit (µPMU) is used, the current phasor data of the distribution network can be collected quickly and accurately, and the real-time network topology reconfiguration judgment conditions are constructed on this basis. Data from Supervisory Control and Data Acquisition (SCADA) system and µPMU are used to estimate the state of the distribution network. Furthermore, the actual µPMU measurement data is used to match the operating mode with the state estimation results under various network topology modes, and the operating network topology structure can be determined. The IEEE 33-bus model is used for the algorithm validation.
