Abstract：Considering the wide application of feeder terminal equipment(FTU)in feeder automation system,a fault location method of distribution network based on FTU is proposed. Firstly,the FTU state vector is formed according to the fault telegram re?ported by FTU,and the simulated fault current vector is calculated by combining the correlation matrix which reflects the network to?pology of the distribution network. Then,the fault section The voltage phasor at both ends is substituted into the fault location equa?tion derived from the impedance method to calculate the distance from the beginning of the fault point to the fault point. The algo?rithm completes the fault segment location and fault location by FTU remote telemetry and telemetry information. It not only can quickly isolate the faulty segment and restore the power supply in the non-fault area,but also on the basis of fault location,Fault lo?cation,to avoid the traditional ranging method of false fault point problem. Finally,the simulation and simulation of the actual situa?tion of the distribution network are carried out to verify the effectiveness of the method.
