In order to help the secondary team staffs improve the efficiency of the maintenance in smart substation, a “one-click” automatic generation method for overhaul safety measures is given in this paper. Based on the principle of safety maintenance for smart substation, the paper describes the rules of dividing boundary for safety maintenance and dose some research work about establishing the database of devices accompanied to stop running. According to engineering models in SCD file, the types and functions of the secondary measures are summarized in this paper. Finally, a complete execution flow of “one-click” automatic generation method is shown in the paper. The results of application in actual engineering indicates that the method offered in this paper is effective and has a good prospect.
