Methods Of Fault Phase Selector And Location Based On Fault Oscilloscope Information Management System

Based on the information recorded against the wave hierarchical distributed network fault diagnosis system study, in combination with the characteristics of model fault component and related components phase selector ,this paper presents a comprehensive programmer of election. At the same time, the single-terminal location in accordance with the characteristics of various types of faults, fault analysis and use of a zero measurement, which can be eliminated on transition resistance and impact on the operation of a single terminal location method. View of the current two-terminal location algorithm computation, and many algorithms call for the amount of information synchronous dual-issue. By using asymmetric fault lines occur when voltage and current characteristics of the negative-sequence component (the fault of the highest negative sequence voltage) analysis and calculation, which is derived from the double-precision positioning algorithm. And paper presents two kinds of simple and feasible method to achieve the ends of the data synchronization.
