Research On Fault Line Selection In System With Non-effectively Earthed Neutral

For a long time , It is troublesome when it comes to single-phase-grounded fault happened in system with non-effectively earthed neutral. Because the fault single is weak and is easy to receive influence of disturbance, and because the variability of fault condition and movement way, some methods already proposed and obtained the application all exist the certain flaw, they are unable to adapt the changeable fault situation.Based on the deep analysis into the fault line selection in distribution systems, the paper includes all kinds of methods and pays more attention to essential problem.It is a breakthrough to extract key information from fathomable electrical measurements with appropriate mathematics tool . This thesis discuss the data fusion technology, and inosculate several Fault Line Selection. Thus provides a new method to fault line selection for single-phase grounded fault.
