| Abstract: | This paper puts forwards a method to find the fault location suitable for the condition of all parallel AT power supply system with protection wire The first step is to adopt the method of transfer impedance to deduce the formula of finding fault location under the condition of all parallel AT power supply system with protection wire, the second step is to calculate the impedance in the fault location expression of AT power system with protection wire The problem of calculating impedance without protection wire and under the equivalent circuit is solved. Finally, by simulation with MATLAB/SIMULINK, the method is proved to be applicable for fault location of the all parallel AT power system with protection wire. |
