Abstract：Due to the large number of distributed power access, complex network topology and changeable operation mode, fault diagnosis and location of active distribution network is facing new challenges. The application of phasor measurement units (PMU) in distribution network provides new information for fault diagnosis. In this paper, a real-time updating scheme of synchronous measurement section based on adjacency submatrix is proposed by using the information of the switch position and real-time communication status of PMU, which considers the change of distribution network topology and PMU communication failures. Meanwhile, based on the three-phase voltage and current synchronous phasor data, an adaptive short-circuit fault location algorithm based on the Frobenius norm of time-space characteristic matrix is proposed. Finally, the IEEE 34 node system with distributed generators is built in PSCAD, simulation result verifies the effectiveness of the proposed algorithm.
