Provided is a secondary safety measure visualization method of intelligent transformer station, which can resolve the technical problem of the prior art that the secondary safety measure of the relayprotection device maintenance at the site of the intelligent transformer station cannot be effectively executed and maintained. The secondary safety measure visualization method comprises the steps ofcollecting the work ticket of the secondary safety measure of the intelligent transformer station and preparing a secondary safety measure work ticket template; producing a visualized device and obtaining the transformer station configuration description file SCD of the present version, and analyzing SCD information; connecting to an intelligent electronic device IED with the visualized device, and establishing an intelligent electronic device IED model based on the SCD information, and improving the intelligent transformer station model; conducting visualized display of the execution state of the work ticket, and checking the report control block and data set state and related data of the transformer station. The invention is advantageous in that the work ticket flow is standardized; maintenance time is shortened; labor productivity is raised; the examination and detection workload of the protective device and the secondary loop can be reduced; the problem of incomplete or excessivesafety work can be prevented.
