The invention discloses a safe and efficient power system abnormal state detection terminal, and belongs to the technical field of power system recovery and control, and the method comprises the steps: building a plurality of types of false data injection attack models which comprise mixed data of SCADA and PMU and are composed of objective functions and constraint conditions, setting a plurality of different attack situations to simulate privacy data of different power grid clients; according to the safe and efficient power system abnormal state detection terminal adopting the above steps, the defects of an existing attack detection method are overcome, and the safety and efficiency of the power system abnormal state detection terminal are improved. A federated learning framework is used for carrying out cooperative training on data among a plurality of clients, the problem of low accuracy caused by insufficient sample data volume is solved while the data among different clients are protected, and finally a
