Method for Disorder Display of Terminal Unit in Power Distribution Automation System

The present invention is to determine the to be, installed in each section to the line terminal equipment to measure the voltage, current and phase difference of the line, broken line detecting device and the failure on the fault indication generated in the terminal device method whether in distribution automation systems the terminal in the fault section detection method in a power distribution system comprising a central control unit for controlling the operation of the apparatus, the phase measurement step of measuring the position in the terminal apparatus, a phase comparator for comparing the phase of the video current phase and direction of fault current calculation, and it includes the step of generating a fault indication information through the direction of the fault current. In distribution automation system in accordance with the present invention according to the failure display method for generating a terminal device, obtain the phase of the video voltage in addition to the principle of failure only by the size and duration conditions of existing video current indicator generate information phase and sequence current , based on the phase of the video voltage compares the phases of the current image should only be considered under certain conditions was to generate a failure indication information.
