The invention relates to an override trip prevention method suitable for a switching station. A self-adaptive protection method is adopted, and optimal protection principles are selected according todifferent fault types. When an inter-phase short circuit fault occurs on an outgoing line of the switching station, the faulted outgoing line is judged by adopting a self-adaptive current quick breakprotection and self-adaptive over-current protection combined method, and incoming line protection is blocked by communication after outgoing line protection is started, so that override trip is prevented; and when a single-phase ground short circuit occurs on the outgoing line, the faulted outgoing line is judged by adopting a method for identifying ground capacitance, the outgoing line protection is started, and the incoming line protection is blocked by communication, so that the override trip is prevented. The problem of the override trip possibly caused when a single-phase ground fault occurs on the outgoing line of the switching station is solved, and meanwhile, the override trip prevention performance of the switching station is improved, so that under different operation modes anddifferent fault types of a system, the optimal protection effect can be achieved.
