Fig. 1 is a flowchart of a power distribution network scheduling method according to an embodiment of the present invention, where this embodiment is applicable to a situation where a power distribution network schedules service operation, the method may be executed by a power distribution network scheduling device, the power distribution network scheduling device may be implemented in a form of hardware and/or software, and the power distribution network scheduling device may be configured in an electronic device, such as an OCS. As shown in fig. 1, the method includes:
s101, obtaining operation information input by a user, wherein the operation information comprises operation equipment and operation behaviors.
The operation information is used for recording the operation of the user on the operation equipment. The operation device refers to a device operated by a user, the name of the operation device, the unique ID of the operation device, and the like are marked on the operation device, and the operation device may include a sensor, a transformer, a line, or the like. The operation behavior refers to the operation of the user on the operation device, and may include closing, separating, sending information, and the like. Wherein, the closed position can be a closed circuit loop which represents that the operating equipment is in a normal operation state; the divide bit may be an open circuit loop representing that the operating device is in a non-operational state.
And S102, generating an operation ticket according to the operation information, and sending the operation ticket to a scheduling management system.
The operation ticket may be a written command for approving work on the electrical device, and the operation ticket is used to instruct the operation of the operation device. For example, the operation ticket is generated and then sent to an executing user who operates the operation device. The operation information specifies what kind of operation is performed for which device, and the generated operation ticket specifies that the corresponding operation is performed for the same device. And generating an operation ticket according to the operation information, wherein the specific content of the operation is acquired, and the operation ticket in a standard format is generated so as to instruct the equipment to execute a corresponding instruction or a user to perform a corresponding operation on the equipment.
The scheduling management system is a system for executing a scheduling command on the power distribution network, and may be an OMS. Illustratively, according to the operation information of pulling the switch No. 1 by the user, an operation ticket is generated and sent to the OMS.
S103, receiving at least one operation instruction corresponding to the operation ticket sent by the scheduling management system.
The operation ticket can be converted into at least one operation instruction. The operation instruction is a command for executing an operation, and the operation instruction may correspond to operation information for generating an operation ticket. Wherein one operation corresponds to one operation instruction. It should be understood that the operation order in the operation ticket is at least one. The operation of the operating device by the user may be more than one, may be one, or may be plural. For example, if the user performs a checking operation on the switch No. 1, the operation is converted into an operation instruction in the operation ticket, and there is only one operation instruction in the operation ticket. For example, the user performs the following operations on the switch No. 1: the operations of opening the switch No. 1, closing the switch No. 1, checking the switch No. 1 and taking down the switch No. 1 can be converted into four operation instructions in the operation ticket, so that the operation ticket has four operation instructions. The electronic equipment executing the power distribution network scheduling method provided by the embodiment of the invention receives at least one operation instruction corresponding to the operation order sent by the scheduling management system. The electronic device executing the power distribution network scheduling method provided by the embodiment of the present invention, hereinafter referred to as the electronic device, may be an OCS. Illustratively, the OCS receives at least one operation instruction corresponding to the operation ticket sent by the OMS.
And S104, executing operation instructions corresponding to the operation tickets.

According to the technical scheme of the embodiment of the invention, the operation ticket is generated by acquiring the operation information input by the user, and the generated operation ticket is sent to the scheduling management system; receiving at least one operation instruction corresponding to an operation ticket sent by a scheduling management system; and executing the operation instruction corresponding to each operation ticket. The technical scheme of the embodiment of the invention realizes automatic real-time interactive linkage of the electronic equipment, and avoids the repeated switching of workers among a plurality of systems in the electronic equipment, thereby reducing operation errors, improving the working efficiency and further improving the safety and reliability of the dispatching service of the power distribution network.
On the basis of the technical scheme, the operation information input by the user is acquired by the following steps: showing a distribution network topological graph to a user; receiving an operation device designated by a user; displaying an operation behavior set corresponding to the operation equipment to a user; receiving an operation behavior corresponding to operation equipment appointed by a user in an operation behavior set; and determining the operation equipment and the corresponding operation behavior as the operation information input by the user.
The topological diagram of the power distribution network refers to the fact that operation equipment in the power distribution network converts the whole power distribution network into a power diagram according to the connection mode between the operation equipment and the power distribution network, and the power diagram is composed of nodes and lines. Wherein, the nodes in the power diagram represent the operating devices, and the lines in the power diagram represent the connection relationships between the operating devices. The set of operational behaviors includes operational behaviors that can operate on the operating device. The operational behavior is typically preset and a set of operational behaviors is generated.
Specifically, the electronic equipment firstly displays a distribution network topological graph for a user to check, and the user specifies an operation device to be operated on the distribution network topological graph; then, the electronic device receives the operation device appointed by the user, inquires the operation behavior set corresponding to the operation device, and displays the operation behavior set to the user for viewing. Then, the user specifies an operation behavior performed on the operation device from the operation behavior set corresponding to the operation device. And finally, determining the operation equipment and the corresponding operation behavior as the operation information input by the user.
According to the technical scheme of the embodiment of the invention, the process of acquiring the user input information is described in detail, so that the operation information does not need to be manually input into the electronic equipment in the whole process of acquiring the user input information, the operation equipment is specified from the power distribution network topological graph of the electronic equipment, and the operation behavior corresponding to the operation equipment is specified from the operation behavior set corresponding to the operation equipment in the electronic equipment, so that the risk caused by manual input errors is avoided, the operation errors are reduced, the operation safety and the control safety of the power distribution network are improved, and the operation ticket is generated in a point diagram ticket forming mode, so that the working efficiency is improved.
Example two
Fig. 2 is a flowchart of a power distribution network scheduling method according to a second embodiment of the present invention, where on the basis of the second embodiment, the embodiment implements the operation instruction corresponding to each operation ticket, and the implementation is as follows: acquiring the type of an operation instruction; and executing the operation instruction correspondingly according to the type of the operation instruction. As shown in fig. 2, the method includes:
s201, obtaining operation information input by a user, wherein the operation information comprises operation equipment and operation behaviors.
And S202, generating an operation ticket according to the operation information, and sending the operation ticket to a scheduling management system.
S203, receiving at least one operation instruction corresponding to the operation ticket sent by the scheduling management system.
And S204, acquiring the type of the operation instruction.
The type of the operation instruction refers to the category to which the operation instruction belongs, and may include a maintenance instruction, a message sending instruction, a risk-free instruction, and the like. The maintenance instruction refers to an instruction for checking or maintaining the operating equipment; the message sending instruction may be an instruction for sending a message to the operating device by the electronic device, or an instruction for sending a message to another operating device or the electronic device by the operating device; the risky instruction refers to an instruction which brings risks to the operation of the power distribution network when the operation equipment executes the instruction; the non-risk type instruction refers to an instruction which does not bring risks to the operation of the power distribution network when the operating equipment executes the instruction.
For example, the present electronic device, such as the OCS, has classified the operation commands that the user may perform on the operation device, and generates a corresponding command library, such as a service class command library and a sending message class command library. After a user specifies an operation behavior corresponding to an operation device in an operation behavior set of the OCS, determining the operation device and the corresponding operation behavior as operation information input by the user; generating an operation ticket according to the operation information, and sending the operation ticket to the OMS; the OCS receives at least one operation instruction corresponding to the operation ticket sent by the OMS, compares the operation instruction with the instruction in the instruction library and is used for acquiring the type of the operation instruction; and correspondingly executing the operation instruction according to the type of the operation instruction.
And S205, correspondingly executing the operation instruction according to the type of the operation instruction.
Different types can be preset to correspond to different execution modes, the execution mode is determined according to the corresponding relation between the type and the execution mode and the type of the operation instruction, and the operation instruction is executed in the execution mode.
According to the technical scheme of the embodiment of the invention, the operation instruction corresponding to each operation ticket is determined by obtaining the type of the operation instruction, so that the safety of executing the operation instruction corresponding to each operation ticket is ensured, and the overhaul or re-execution caused by risk of the operation instruction is avoided, thereby reducing operation errors, improving the working efficiency and further improving the safety and reliability of the dispatching service of the power distribution network.
On the basis of the technical scheme, the operation instruction is correspondingly executed according to the type of the operation instruction, and the implementation is as follows: executing the operation instruction under the condition that the type of the operation instruction is a risk-free type; under the condition that the type of the operation instruction is a risky type, manually verifying the operation instruction; executing the operation instruction under the condition that the manual verification input by the user is passed, and verifying the operation rule in the execution process of the operation instruction; and executing the operation instruction under the condition that the operation rule passes the verification.
Specifically, in S2051, when the type of the operation instruction is the risk-free type, the operation instruction is executed.
The operation instruction of the risk-free type may include setting, listing and the like. Wherein, setting means setting the state of the operation device from "0" to "1"; "0" may represent that the operation device is in a non-operation state, and "1" may represent that the operation device is in an operation state. The hang tag means that operation of operating equipment in the power distribution network is forbidden, and hang the hang tag marked with relevant prompt information, for example, the hang tag for power failure maintenance can be hung, firstly, the operation of operating equipment in the power distribution network can be forbidden, and secondly, the hang tag for 'someone works and forbids switching on' can be hung. Specifically, when the type of the operation instruction is a risk-free type, it is indicated that the operation instruction is directly executable without manual review, and thus the electronic device directly executes the operation instruction.
