| Nowadays, the automatic system is not smart enough due to the complexity and large amount of nodes and branches in distribution network. Thus, related staff should be sent to accident scene and repair the fault for restoring power supply after the fault occurred. Relatively speaking, the fault locating based on distribution network automatic system operates as follows:the data collection units and comuncaiton units will send the information to the master if the fault occurred. Then, the master will make the decision automatically after distinguished the fault according to the operation modes of transformer substations.Aiming at the status of distribution network, this paper studies on the strategy of fault location and rapid emergency repair, which is defenitiely a useful supplement to the distribution automation system. In order to solve the technical fault location problems of distribution network, the fault section of the fault section is realized by the method of the whole current single phase earth fault criterion and the improved matrix algorithm. The fault location monitoring device is studied to realize the fault diagnosis and fault diagnosis. The fault location of distribution network based on the expert system and the system of automatic and rapid emergency repair are studied in 10kV graphics. The research results of this thesis have a certain improvement on the power supply reliability of distribution network, and it is of great significance to improve the reliability of power supply. |
