Fault Diagnosis Technology and Its Application for Distribution Network Based on Electricity Information Acquisition System

On the needs of refined management of State Grid,considering the shortage of monitoring devices for distribution automation,and the actual demand of fault diagnosis for distribution network,data is acquired from main operational system of electricity grid,such as electricity information acquisition system and so on. Then the data is integrated with 10 k V distribution network geographical diagram in new developed software. According to which,the instant judgment and visualization of fault information in distribution network are realized,by means of the programming with special fault diagnosis logic. Practice shows that it can provide the efficient evidence for finding faults in distribution network rapidly. At the same time,it makes the power distribution dispatching more intelligent,through the real time monitoring of power,voltage,current of customers in distribution network.
