[0002] As the scale of the power grid continues to expand, the number of equipment under jurisdiction continues to increase, and the requirements for power supply reliability are becoming higher and higher. After the implementation of the integrated control mode, the dispatcher can independently remotely operate the substation equipment, and there is no need for on-site personnel to cooperate in inspection. However, since the knife switch equipment only sends position change information to the dispatching automation system, it does not have other criteria such as current and voltage changes to assist in judging the remote control results. It cannot meet the requirements for on-site equipment remote control and there is a risk of inadequate operation. Therefore, it is very important to evaluate the knife switch equipment before remote control operation.

[0061] The embodiments of the present invention provide a method and system for risk assessment of remote control operation of knife switches, which are used to solve the technical problem that before remote control operation, manual analysis of relevant knife switches involved in the operation ticket is mainly relied on. However, due to the manual evaluation method, the efficiency is extremely low, and the accuracy depends entirely on the skill level of the personnel, and it is impossible to accurately screen out relevant knife switches with problems, thereby reducing the reliability of power grid operation.

The dispatching automation system can collect the status data of switches and knife switches in the station, write the data into the E file, and send it to the third safety zone through positive isolation. The dispatching command and control system collects the operation ticket (item-by-item order, comprehensive order, single order) information and operation item details information, and pushes them through the data interface. The three-risk linkage system collects knife switch ledger information and pushes it through the data interface. The data synchronization service can receive the E file from the dispatching automation system and parse it and store it in the auxiliary decision-making cockpit database, and at the same time call the dispatching command and control system interface and the three-risk linkage interface to extract the operation ticket data and knife switch ledger data to the auxiliary decision-making cockpit database. The auxiliary decision-making cockpit database contains switch knife switch status table, equipment table, plant station table, listing information table, equipment topology table, operation ticket information table, knife switch ledger information table, etc., which can receive the data parsed by the knife switch remote control risk assessment system and store it in the specified library table. The risk analysis module can return the risk analysis result of the device N-1 according to the received device number. The knife switch remote control risk assessment system can read the switch knife switch status table, equipment table, plant station table, listing information table, equipment topology table, operation ticket information table, knife switch ledger information table and other data from the auxiliary decision cockpit database. After analysis, the analysis results will be sent to the telephone platform and the large-screen visualization platform.

[0072] Step 104: perform risk assessment on the switch information according to the auxiliary decision cockpit database to obtain corresponding assessment results.

[0073] In an embodiment of the present invention, risk assessment is performed on the switch information according to the auxiliary decision cockpit database to obtain an assessment result corresponding to the target operation ticket.

[0074] In an embodiment of the present invention, the present invention obtains corresponding knife switch information by filtering the information of the auxiliary decision cockpit database according to the first keyword and the text information of the operation item, and then performs risk assessment on the knife switch information through the auxiliary decision cockpit database to obtain the corresponding assessment result, thereby effectively improving the accuracy of risk assessment of knife switch remote control operation, and overcoming the technical problem that the manual analysis of the relevant knife switches involved in the operation ticket before remote control operation is mainly relied on, but due to the extremely low efficiency of the manual assessment method, and the accuracy depends entirely on the skill level of the personnel, it is impossible to accurately screen out the relevant knife switches with problems, thereby reducing the reliability of power grid operation. Compared with the traditional assessment method, the present invention filters the information of the auxiliary decision cockpit database according to the first keyword and the text information of the operation item to obtain the corresponding knife switch information, and can quickly screen out the relevant knife switches that need to be evaluated, and performs risk assessment on the knife switch information according to the auxiliary decision cockpit database, accurately screens out the relevant knife switches with problems, thereby improving the reliability of power grid operation.

[0149] S26. When any action time is less than or equal to the time threshold and any risk level is less than the risk threshold, an assessment result that the remote control operation of the knife switch is risk-free is generated.

[0150] In an embodiment of the present invention, when each action time is less than or equal to 3 years and each risk level is less than level 3, an assessment result that the remote control operation of the knife switch is risk-free is generated.

[0151] In an embodiment of the present invention, the present invention obtains corresponding knife switch information by filtering the information of the auxiliary decision cockpit database according to the first keyword and the text information of the operation item, and then performs risk assessment on the knife switch information through the auxiliary decision cockpit database to obtain the corresponding assessment result, thereby effectively improving the accuracy of risk assessment of knife switch remote control operation, and overcoming the technical problem that the manual analysis of the relevant knife switches involved in the operation ticket before remote control operation is mainly relied on, but due to the extremely low efficiency of the manual assessment method, and the accuracy depends entirely on the skill level of the personnel, it is impossible to accurately screen out the relevant knife switches with problems, thereby reducing the reliability of power grid operation. Compared with the traditional assessment method, the present invention filters the information of the auxiliary decision cockpit database according to the first keyword and the text information of the operation item to obtain the corresponding knife switch information, and can quickly screen out the relevant knife switches that need to be evaluated, and performs risk assessment on the knife switch information according to the auxiliary decision cockpit database, accurately screens out the relevant knife switches with problems, thereby improving the reliability of power grid operation.
