System and method for automatically detecting functions of feeder line

The invention provides a method for automatically detecting functions of a feeder line. The method comprises the following steps of: analyzing classical faults appearing in a power distribution network, defining a universal pre-defining fault signal generating module and a treatment scheme; using a real-time power grid model for a feeder line fault analogizing and detecting platform, and generating a corresponding fault analog signal and a corresponding fault treatment scheme based on a pre-defined feeder line fault mode; receiving the analogized fault signal by a detected power distribution automatic system, generating and performing a fault treatment scheme according to the self-setting strategy; receiving and comparing the fault treatment scheme with the pre-defined treatment scheme by the feeder line fault analogizing and detecting platform. The method disclosed by the invention is used for generating a fault signal by a pre-defined fault mode and injecting the fault signal into a to-be-detected power distribution automatic system to trigger the fault treatment function of a to-be-detected system, receiving and comparing the fault treatment scheme of the to-be-detected system on line with the fault treatment scheme produced by the fault analogizing and detecting system and (or) manually set to automatically generate the detected results.
