Abstract

It makes the topology of distribution network more complex to contain a lot of distribution generations (DGs) in it. For this reason, a fault location approach suitable to the distribution network containing DGs is proposed. Firstly, according to the results of power flow calculation, a database of voltage sag is established; then the power quality information is acquired by power quality monitors and correlation analysis on collected nodal voltage data and voltage sag data of the established database is performed; and then the node with the matching extent value most close to 1 is determined as the fault point. Simulation results of IEEE 33-bus system show that the proposed approach is effective and using the proposed approach the misjudgment can be prevented. Finally, the results of the analysis on the influences of different load models, transition resistances, connection and disconnection of DGs on the proposed approach show that the proposed approach possesses better robustness and reliability.
