The invention discloses an identification method based on a fault indicator false alarm signal, comprising steps of establishing internal memory topology of a primary/secondary device of a power distribution network through a power distribution network topology model in a power distribution automatic master station system, recording history topology relations before device power outage, obtaining an alarm signal of a fault indicator on a feeder by the power distribution master station system when power outage happens to the feeder, identifying a real effective alarm signal of the fault indicator according to a designed logic algorithm by the power distribution master station system, and recording a whole analysis process and all data related in the whole analysis process by the power distribution master station system. The identification method based on the fault indicator false alarm signal can greatly improve working efficiency of network scheduling and emergency maintenance of the power distribution network.
