(1) defining the type of an operation ticket; according to the summary of the actual safety measure operation flow, the types of the operation tickets are divided into soft pressing plate switching, hard pressing plate switching and primary equipment operation;
(2) from a summary of the soft platens that may operate in the safety instrumented workflow, a classification of soft platens is defined as follows: the device comprises a GOOSE receiving soft pressing plate, a GOOSE sending soft pressing plate, an SV receiving soft pressing plate, an SV sending soft pressing plate and a protection function soft pressing plate;
(3) classifying in the steps, and establishing a safety measure ticket model which comprises the safety measure step number, the operation type, the operation object, the target state and whether the safety measure of the corresponding operation step is finished;
according to the characteristics of the safety measure operation flow execution, defining a safety measure ticket model as an ordered set of the operation steps;
(4) the method comprises the steps that a secondary circuit is automatically generated through analysis of an SCD file, the secondary circuit is divided into an editing state and an operating state, when in the editing state, a system automatically identifies a pressing plate selected by a user according to actions of a mouse, and pops up a selection frame to enable the user to select a target state; and importing the results of adding, deleting and editing by the user into the safety measure ticket model to generate a safety measure ticket, storing the safety measure ticket in a database, and finally generating a safety measure ticket library.
The specific method for verifying whether the safety measure ticket is correct in the step 2 is as follows:
(1) establishing a secondary equipment safety isolation rule base;
(2) automatically analyzing the SCD file, and establishing a secondary virtual circuit connection relation between the devices and a connection relation between the virtual circuit and the soft pressing plate;
(3) and automatically verifying the correctness of the operation ticket according to the safety isolation rule of the secondary equipment and the virtual circuit connection.
The isolation of the secondary equipment of the transformer substation must follow a certain principle, for example, the safety measure principle of the secondary equipment when the device at the power failure is abnormal:
1) the bus is withdrawn to protect the SV receiving soft pressing plate;
2) the exit bus protects the GOOSE failure receiving soft pressing plate of the interval;
3) the isolated disconnecting link is put into the bus protection to forcibly divide the soft pressing plate;
4) exiting the interval line protection GOOSE to start the failure sending soft pressing plate;

The safety measure monitoring in the step 4 includes monitoring 3 stages of a safety measure execution stage, a safety measure overhaul stage and a safety measure recovery stage, and a process for judging whether the safety measure execution process is incorrect is shown in fig. 2, and the specific method is as follows:
(1) analyzing the safety measure ticket selected by the user, analyzing the pressing plate and the target state to be operated in each safety measure step from the safety measure ticket, and corresponding the safety measure step number to the pressing plate; the target state is the state that the pressing plate should reach after safety measures are finished;
(2) reading the current states of all pressure plates related in the safety measure ticket from the device through an MMS (Internet message service) message based on IE61850 commonly used by the intelligent substation, judging whether the current state of each pressure plate is consistent with the target state of the pressure plate, if the current state of one or some pressure plates is consistent with the target state of the pressure plate, judging that the condition for executing the safety measure is not met, considering that the current state is not consistent with the condition for executing the safety measure, and giving a risk prompt; if the target state of a certain pressure plate is 1, the state of the pressure plate before safety measure execution is 0, if the condition that the state of the pressure plate before safety measure execution is 1 is detected, the pressure plate cannot carry out safety measure, and therefore the current state of the pressure plate is considered to be not in accordance with the condition of safety measure execution;
(3) after safety measure monitoring is started, reading the current states of all pressure plates related in a safety measure ticket from the interlayer device through an MMS message, comparing the current states with the target states of all pressure plates in each safety measure step, and judging whether the current states are consistent; if the two steps are not consistent, the safety measure execution process is judged to have errors, if the safety measure process is ten, safety measure is carried out on one pressing plate in each step, and the target states of all the pressing plates in each step are shown in table 1.
TABLE 1
| Pressing plate 1 | Pressing plate 2 | Pressing plate 3 | Pressing plate 4 | Pressing plate 5 | |

| Step 3 | 1 | 1 | 1 | 0 | 0 |
| Step 4 | 1 | 1 | 1 | 1 | 0 |
| Step 5 | 1 | 1 | 1 | 1 | 1 |
When judging whether the safety measure execution flow has errors or not, the step to which the safety measure flow is executed is not required to be detected, the states of all the pressing plates are only required to be monitored in real time, when the states of all the pressing plates at a certain moment are detected to be 11000, the step 2 can be judged to be executed completely, if the states of all the pressing plates at a certain moment are detected to be 11010, the step 4 can be judged to be executed completely, but the step 3 is not executed, and the safety measure flow can be known to have errors.
And the safety measure recovery stage is used for recovering the target state of each pressure plate after the safety measure execution is finished to the initial state, the sequence of the operation on each pressure plate is strictly opposite to the sequence of the safety measure execution, but the monitoring on the recovery process is the same as the safety measure execution process. The safety measure maintenance stage is a stage of maintaining the pressure plate with problems in the safety measure process, switching operation needs to be carried out on the pressure plate with the problems, and when a certain pressure plate is operated, the state change of the pressure plate is prompted to a user in a dynamic display mode.
