Abstract：With the continuous development of the power grid and the deepening of the electricity market reform on the safety of the power grid operation and power quality requirements continue to improve, for the original maintenance methods "short current, off voltage, split trip" such security measures are not suitable for digital substation The actual situation. In this paper, an intelligent substation secondary maintenance security automatic generation technology is proposed, which automatically generates the security ticket through three strategies: the first through the security strategy in the security, analysis of the connection between intelligent devices to determine the maintenance of equipment and Isolation of the running equipment; the second through the security of the soft plate and virtual loop corresponding strategy, analysis of maintenance equipment, such as "jump" to obtain the reference name, mapping the trip soft plate, to achieve the pressure of the pressure plate to solve the key to repair equipment Such as "current", "voltage", to achieve SV soft platen retraction; third in the security of the automatic generation of the order strategy, analysis of maintenance equipment, soft and hard pressure plate to determine the operation order of the security ticket. Improve the intelligent substation site technical transformation, elimination, verification of the work efficiency, while reducing the human factors caused by work error.
