Topology Identification of Distribution Network Based on Nodal Power Injection
摘要
Abstract
Erroneous remote signal in distribution supervisory control and data acquisition ( DSCADA ) decreases the reliability of distribution network topology of remote signaling data. With adopting multi-sampling of power injections by micro synchronous phasor measurement unit (μPMU ) , this paper constructs the variance model of the branch voltage deviation based on the measurement of nodal power injection. The Kruskal algorithm is used to obtain the minimum spanning tree with the variance of the branch voltage deviation as the line weight to achieve the identification of operation topology structure of distribution network, and then the influence of the sampling times of the power injection data and the complexity of the distribution network on the identification errors is analyzed. The simulation results of IEEE 33 and IEEE 123 node system show that the algorithm has good reliability and practicability for the topology identification in distribution network.关键词
