The return order subunit is used to synchronize the result of the switching operation with the dispatch information management system according to the dispatch order after the operation is completed.

The real-time SCADA system interaction unit includes a synchronous power grid model module and a real-time data section acquisition module; before the monitoring dispatcher generates the first operation ticket according to the dispatch command received, the real-time SCADA system interaction unit is used to synchronize the power grid model, graphics and Real-time data. The monitoring operation ticket process management unit generates operation tickets according to the real-time synchronous power grid model, graphics and real-time data. When the first operation subunit and the second operation subunit review the operation ticket generated by the switch operation, they call the safety check interface unit to check whether the operation instructions in the operation ticket comply with the error prevention rules, and whether the operation result of the check is It will bring serious line overload or limit violation.

The convenience and efficiency of management work.

Fig. 2 is a flow chart of the intelligent monitoring operation ticket management method provided by the present invention. It specifically includes the following steps: First, through the interactive interface with the real-time SCADA system, automatically synchronize the grid model, graphics and real-time data, and generate the current connection diagram according to the real-time data; judge whether there is a switch operation in the dispatch command, if there is no switch operation in the dispatch command , the first transfer operation is performed; otherwise, the first ticket drawing operation is performed, and the first operation ticket is generated according to the current connection diagram and the current state and target state of the equipment to be operated. Then, enter the first duty chief audit, and perform security verification on the generated operation ticket. If the security verification fails, the operation ticket operation is prohibited; otherwise, the operation ticket is forwarded to the centralized control station for unified operation, and the intelligent All information records generated during the execution of the monitoring operation ticket are stored in the dispatching information management system. Finally, it is judged whether there is a second switch operation in the scheduling command, if there is no second switch operation, the monitoring operation ticket management ends; otherwise, repeat the above steps. The following is a detailed description of this process.

S1, through the interactive interface with the real-time SCADA system, automatically synchronize the real-time data section, generate the current connection diagram according to the real-time data section; judge whether there is a switch operation in the dispatch command, if there is no switch operation in the dispatch command, turn to step S4, and proceed to the first step A transfer operation; otherwise, turn to step S2 and perform the first drafting operation.

Through the interactive interface with the real-time SCADA system, the grid model, graphics and real-time data are automatically synchronized, and the current connection diagram is generated according to the real-time data. Among them, the synchronous power grid model realizes the horizontal integration of various applications of the dispatch center, and vertically connects the models, graphics, real-time data of all levels of dispatch and the unified service of five-level dispatch standard naming. It effectively solves the problem that the standard name of scheduling terms cannot be checked in the old system.

Through the interactive interface with the real-time SCADA system, the real-time data section is automatically synchronized, the section management service provided by the smart grid dispatching technical support system, and the data mirroring synchronization technology is used to read the real-time data of the SCADA system, which not only improves the efficiency of data synchronization and data integrity, and enhanced system stability and security. Then generate the current connection graph according to the real-time data, so as to obtain the real-time connection relationship of the equipment to be operated when generating the operation ticket. Generate operation steps based on the connection relationship.

Through the interactive interface with the real-time SCADA system, after the real-time data section is automatically synchronized, the data in the intelligent monitoring operation ticket management system is the real-time data during the actual operation of the power system, and the operation ticket can be generated according to the real-time data by analyzing the scheduling command. Before generating the operation ticket, it is judged whether there is a switch operation in the dispatch command, if there is no switch operation in the dispatch command, then turn to step S4, and perform the first transfer operation; otherwise, turn to step S2, and perform the first ticket drafting operation.

S2. Generate a first operation ticket according to the current connection diagram and the current state and target state of the equipment to be operated.

Determine the device to be operated and the target state of the device to be operated according to the scheduling command, obtain the current state of the device to be operated and the connection relationship with other devices through the current connection diagram obtained in step S1, according to the current state of the device to be operated, the target state and The connection relationship with other devices generates the first operation ticket.

In the embodiment provided by the present invention, the ways of generating an operation ticket include intelligent ticketing and phrase ticketing. Smart ticketing means that as long as the target state is selected on the device displayed in the current connection diagram, corresponding operation instructions can be generated on the operation ticket according to the current state and target state of the device. This ticketing method is intuitive and convenient. Phrase ticketing adopts automatic semantic matching technology, as long as the plant station, operation object and operation status are selected, a complete operation instruction can be generated on the operation ticket. The operation ticket contains detailed content, such as confirming that the switch interval screen has been called up, checking that the switch is in the target position, checking the switch telemetry data, etc.

S3, perform security check on the generated operation ticket, if the security check fails, prohibit the operation of the operation ticket; otherwise, go to step S4, and perform the transfer operation.

In the embodiment provided by the present invention, the security verification includes topology error prevention verification and power flow analysis verification. Among them, the topology anti-error verification checks the content of the operation ticket. On the one hand, it checks whether the content of the ticket can achieve the operation purpose; on the other hand, it checks whether the operation instruction complies with the anti-error rules. and other operation rules, the operation content of this operation ticket cannot be operated. In the embodiment provided by the present invention, topology anti-mischecking is through network topology analysis, supplemented by relevant safety operation rule criteria, such as the blocking function between one equipment operation (cannot pull the knife switch with load, cannot Ground wire power transmission, etc.), it can realize the misoperation judgment function under any wiring mode.

Among them, network topology analysis, also known as "network connection analysis", is mainly used to generate bus and network models for power grid analysis based on the status of switches, switches and other equipment in the smart grid and the connection relationship of various electrical components.

Power flow analysis and verification supports calling the dispatcher's power flow system, which can trigger the dispatcher's power flow system before ticket drafting and execution, perform grid power flow calculations, obtain line overload and limit violation information, and automatically synchronize to the dispatching information management system for supply Dispatcher reference. In the embodiment provided by the present invention, the power flow analysis verifies the power flow change in the power system caused by the operation command of the operation ticket, and verifies whether the operation result will bring serious line overload or limit violation.

If the generated operation ticket does not pass the security verification, the operation of the operation ticket is prohibited, and a new ticket is drafted. Otherwise, forward the operation ticket to the centralized control station for unified operation.

S4, forward the operation ticket to the centralized control station for unified operation, and at the same time store all information records generated during the execution of the intelligent monitoring operation ticket into the dispatching information management system.

If the generated operation ticket passes the security verification, the operation ticket will be forwarded to the centralized control station through the transfer operation for unified operation. Before the transfer operation, through the interactive interface with the real-time SCADA system, the automatically synchronized power grid model, graphics and real-time data will be compared with the actual location and status information of the equipment obtained in real time through the camera, and the monitoring operation will be carried out. When the equipment screen is the same as the actual location and status information of the equipment, the operation ticket is forwarded to the centralized control station for unified operation.

In the embodiment provided by the present invention, on the one hand, the transfer operation is a dispatch operation that needs to be performed by the centralized control station, mainly the operation of the knife switch, and the monitoring center forwards the instruction to the centralized control station. On the other hand, after the security verification of the operation ticket, the unified operation is carried out through the centralized control station.

Before the operation ticket is uniformly operated through the centralized control station, the topology error prevention function of the safety check is invoked in real time. During operation, in case of accidents, abnormalities, failure of anti-error verification, etc., the operation should be stopped. If the operation task is affected by the above phenomenon, it should be reported to the dispatcher, and the operation ticket should be revised according to the dispatch order; if the operation cannot be performed due to equipment reasons, the operation should be stopped, the reason should be checked, and the dispatcher and production management department should be reported if it cannot be handled. It is forbidden to use abnormal methods to forcibly operate the equipment, which effectively reduces the occurrence of wrong operations and improves the safety of operation tickets.

After the operation is completed, record all the information generated during the execution of the intelligent monitoring operation ticket, such as the content of the monitoring operation ticket, information on drafters, reviewers, guardians, executors, etc., dispatching command transfer records, etc., in the dispatching information Information synchronization is carried out on the management system, and operations such as viewing the above information can be performed on the dispatching information management system, which realizes the support of "cross-regional office" and "multi-regional management" of dispatching management work, and improves the convenience of dispatching management work sex and efficiency.

S5, judging whether there is a second switch operation in the scheduling command, if there is no second switch operation, the monitoring operation ticket management ends; otherwise, a second operation ticket is generated, and steps S3-S4 are repeated.

The dispatcher judges whether there is a second switch operation according to the dispatch command received. If there is no second switch operation, the monitoring operation ticket management ends; otherwise, a second operation ticket is generated and steps S3~S4 are repeated. The second operation ticket is checked for safety, and the operation ticket that passes the check is forwarded to the centralized control station for unified operation. At the same time, all information records generated during the execution of the intelligent monitoring operation ticket are stored in the dispatching information management system.

By generating operation tickets for the first switching operation and the second switching operation, and performing safety checks separately, the safety of the operation is improved, the possibility of wrong operations is reduced, and a powerful guarantee is provided for the safe and stable operation of the power grid. Assure.
