The method comprises the following specific steps:
(1) establishing a device safety measure preview model, and setting safety measure alarm rules
According to the SCD file information, secondary equipment is divided into a relay protection device, a measurement and control device, a merging unit, an intelligent terminal and the like, wherein the relay protection device is divided into different protection types such as line protection, bus protection, main transformer protection, circuit breaker protection and the like according to functions, corresponding alarm logic, locking logic and action logic are set for each device according to the device type, and in the process of pre-enforcement of the safety measure, if relevant signals of the devices meet the logic relationship, corresponding information can be sent out.

(3) Prefarely Ann measure ticket
On the plan for previewing the safety measures, an operator executes each safety measure in sequence according to the contents of the safety measure ticket, and an execution result is displayed on the plan for previewing in real time. After each operation is finished, the preview model judges whether signals are output or not and what signals are output according to logic rules, and the signals are visually displayed. The safety measure strategy rehearsal module 40 judges whether the signal meets the safety measure ticket expectation, and gives a judgment result. After the execution of the safety measure is completed, the safety measure policy rehearsal module 40 may further determine whether the repaired device and the associated device are effectively and correctly isolated.
5. The execution process of the safety measure is checked by the safety measure execution checking module 50.
The checking of the safety measure execution process is mainly divided into two checking types, namely initial value checking and single operation execution checking.
The safety measure execution and verification module 50 is composed of an information acquisition module and a safety measure monitoring module, wherein the information acquisition module comprises an MMS client unit and a GOOSE receiving unit, as shown in fig. 2. The GOOSE receiving unit receives the GOOSE message information in the process layer network and sends the safety measure information in the message to the safety measure monitoring module. The safety measure information mainly comprises pressing plate information, optical fiber on-off information and manual confirmation information. The pressing plate information comprises an SV receiving pressing plate, a GOOSE sending pressing plate, a GOOSE receiving pressing plate, a functional pressing plate and a related hard pressing plate of the IED equipment. The optical fiber on-off information is obtained by the configured optical fiber information. And editing the information which cannot be acquired through communication transmission into manual confirmation information. The safety measure execution checking and verification module 50 comprises the following checking steps:
(1) and the safety measure monitoring module receives and analyzes the safety measure ticket.
After the intelligent safety measure generation module 20 generates a safety measure ticket and transmits the safety measure ticket to the safety measure monitoring module through a TCP (transmission control protocol), the safety measure monitoring module analyzes the content of the safety measure ticket by combining SCD (security coding description) file information. The secondary equipment SV sending platen, GOOSE receiving platen, GOOSE sending platen, functional platen, hard platen associated with the secondary safety measure are all specifically configured as Reference addresses (references) from LD to DA in the SCD file. The safety measure monitoring module analyzes the safety measure ticket information by reading and processing Reference address (Reference) information.
Referring to section DL 860.8.1, the format of the Reference address (Reference) is defined as the mapping relationship from the logical device to the data attribute layer, and the mapping format is defined as: IED/LD/LN $ FC $ DO $ DA with a maximum length of 65 octets.
The safety measure monitoring module can obtain the execution initial state information of the safety measure ticket, the operation content, the operation object and the operation type of the single operation by analyzing the safety measure ticket information.
(2) And checking the initial value.
After the safety measure monitoring module completes the analysis of the safety measure ticket, an initial value checking process is started. The information acquisition module acquires current state information of the safety measure information of the secondary equipment related to the safety measure ticket and sends the information to the safety measure monitoring module, and the safety measure monitoring module judges whether the current state information of the equipment is consistent with an initial value set by the safety measure ticket or not and feeds back a result to an operator in a visual display mode, as shown in fig. 3.
(3) Single operation checking
In the single-operation checking process, the safety measure monitoring module monitors all safety measure information in real time, triggers the single-operation checking after receiving the state change signal of the safety measure information, and feeds back the checking result of the single-operation to the monitoring system. The secondary safety measure execution and check flow is shown in fig. 4 and 5.
The information acquisition module acquires safety measure information related to the safety measure ticket and sends the safety measure information to the safety measure monitoring module, and the intelligent substation safety measure information state change triggers the device to send corresponding GOOSE displacement information and simultaneously triggers MMS report service. The GOOSE displacement information is transmitted to a GOOSE interface unit of the information acquisition module through a process layer network; and the MMS message is transmitted to an MMS client unit of the information acquisition module through the station control layer network.
And after receiving the safety measure information acquired by the information acquisition module, the safety measure monitoring module judges whether the state change of the safety measure information occurs or not. And triggering single operation checking after the safety measure information state changes, and judging whether the safety measure information state changes contain error information or not. Specifically, judging whether the change condition of the safety measure information state of the protection device is consistent with the change expectation of the safety measure ticket operation step, wherein the consistency is 'correct', and the inconsistency is 'error in checking state'; and judging whether the state change condition of the safety measure information is consistent with the expected operation sequence of the safety measure ticket, wherein the consistency is correct, and the inconsistency is wrong in the checking sequence. The safety measure monitoring module displays the checking information of the single operation to an operator through a visual interface, gives alarm information if the checking information shows that the error information exists, and prompts correct operation if the checking information does not show the error information.
(4) Secondary safety measure execution process visualization
