Abstract: A method for locating faults in a power network includes reading power network information stored in a database in a data reading step. A power network matrix is created based on the power network information in a power network creating step. A fault current vector is created in a fault current vector creating step. In a fault locating step, a backward substitution is carried out on the fault current vector and the power network matrix to obtain a detection zone vector, and the fault can be located. The fault locating speed of the power network is, thus, increased.
