The invention discloses a false tripping prevention control method for a secondary circuit of a power distribution network, and relates to the technical field of power distribution networks of power systems. According to the power distribution network secondary circuit false tripping prevention control method, a false tripping prediction value of a power distribution network secondary circuit is obtained based on prediction information of the power distribution network secondary circuit, and the probability of false tripping faults of the power distribution network secondary circuit is displayed; on the basis of real-time monitoring of the switch opening condition of the power distribution network secondary circuit, the opening information of the power distribution network secondary circuit is obtained, whether the power distribution network secondary circuit is abnormal or not is judged, and then the error tripping detection value of the power distribution network secondary circuit is obtained.
