Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
In a centralized scheduling management mode of a power grid, a master station side sequence control operation mode is currently applied, and scheduling utilizes a sequence control program of an OMS (operation management system) or an OCS (online charging system), so that automatic sequential execution operations of issuing, remote control, confirmation and the like of scheduling instruction tickets are realized according to operation contents and sequences of the operation tickets and safe, reliable and flexible research and judgment on electrical equipment. The master station side depends on the OMS and OCS (installed in the terminals located in the centralized dispatching desk) of the dispatching desk side, and the field side depends on the Application (APP) (OMS) installed in the mobile terminal. In the distributed scheduling management mode, sequence control operation cannot be realized at present.
Fig. 1 is a schematic structural diagram of data interaction between an OMS and an OCS, and as shown in fig. 1, an OCS mobile terminal, an OCS server, an OMS scheduling station terminal, and an OCS scheduling station terminal interact with each other. The centralized scheduling and main station side is mainly operated by an OCS scheduling station end and an OMS scheduling station end, and the distributed scheduling and field side is operated by an OCS mobile end.
The intranet 4A platform and 4A in the 4A synchronization server in fig. 1 refer to a solution for a unified security management platform, and include four security management related functions, namely Authentication, authorization, account number, and Audit Audit.
The OCS dispatching station end and the OMS dispatching station end are accessed into an internal network, data interaction is realized through intranet connection, the OCS mobile end is accessed into a mobile communication network, and is accessed into an external network server through a mobile application platform, and then data exchange is realized through the internal and external network exchange platform and the OCS dispatching station end and the OMS dispatching station end which are positioned in the intranet.
The OCS can monitor and control functions of power grid graphics, equipment states, power flows, on-off states and the like. The OMS can be used by a dispatcher to schedule management function services such as ticket planning, order issuing, service form transmission and the like. The OCS mobile terminal is a power grid operation control system (mobile APP) established on the mobile terminal, and a user with a common authority can browse a power grid tidal current diagram, a load curve, an alarm signal and the like and can execute a point diagram ticket forming function. If some users input the key which the dispatching desk applies for examination and verification, the remote control/setting function of the associated equipment can be opened, and the sequential control operation of the dispatching instruction ticket can be executed.
The centralized scheduling means that scheduling personnel, a running management system, a control system and related equipment related to scheduling are centralized in one area, unified scheduling is carried out, and unified command is centralized, which is a common form at present. Distributed scheduling refers to that when centralized scheduling management cannot be achieved in one area due to factors such as irresistible factors, weather disasters or fields and equipment, emergency scheduling right is released or field scheduling is adopted for processing, the form can be called distributed scheduling, original centralized scheduling is not cancelled and still exists with the distributed scheduling, the distributed scheduling is subjected to the centralized scheduling, and key node services still need centralized scheduling, auditing and approving. The sequence control operation refers to scheduling and utilizing an OMS or OCS to execute a sequence control program, and according to the operation content and sequence of the operation order and the safe, reliable and flexible research and judgment on the electrical equipment, the automatic execution of the automatic sequence execution operation such as issuing, remote control, confirmation and the like of the scheduling instruction order is realized.
On the basis of the structure of data interaction between the OMS and the OCS shown in fig. 1, an embodiment of the present invention provides a distributed scheduling sequential control method and system.
Fig. 2 is a flowchart of a distributed scheduling priority control method according to an embodiment of the present invention, and as shown in fig. 2, the distributed scheduling priority control method according to the embodiment includes:
step S210, the OCS mobile terminal generates a scheduling instruction ticket according to a scheduling instruction of the user to the power grid device, where the scheduling instruction ticket includes at least two scheduling instructions, and each scheduling instruction includes an identifier, an initial state, and a target state of the power grid device that is requested to be scheduled.
The embodiment of the invention provides a distributed scheduling sequential control method which is used for performing distributed scheduling sequential control operation on power grid equipment. Firstly, distributed scheduling is triggered by an OCS mobile terminal, the OCS mobile terminal is realized by an OCS established on the mobile terminal, and the OCS is operated by a power grid scheduling personnel on the site of a device to be scheduled on a power grid. The method comprises the steps that a user using an OCS mobile terminal firstly uses the OCS mobile terminal to release a scheduling instruction for the power grid equipment, and a scheduling instruction ticket is generated and comprises at least two scheduling instructions. Each scheduling instruction includes an Identification (ID) of the power grid device requesting scheduling, an initial state, and a target state. The dispatching instruction of the dispatcher to the power grid equipment triggered by the OCS mobile terminal needs to be audited and approved by a management system located at the centralized dispatching terminal. Since the scheduling instruction ticket includes at least two scheduling instructions, it is necessary to determine an execution sequence of the at least two scheduling instructions for different devices, thereby implementing distributed scheduling sequence control.
In an embodiment, the OCS mobile terminal may determine a scheduling instruction of the user to the power grid device according to an operation of the user on the power grid connection diagram on the OCS APP, and generate a scheduling instruction ticket. Namely, in the OCS mobile terminal, a power grid wiring diagram (with real-time data, power flow and graphs and the state of the on-off position of the equipment) is displayed in a graphical mode, and the power grid wiring diagram is switched to a simulation state graph (namely a section graph), so that a user can visually see the state of each equipment in the power grid. The user executes point diagram ticketing on the OCS APP, namely, the initial state of each device is selected to be the 'fen'/'he' state by clicking the graph, and the target state of each device is selected to be the 'fen'/'he' state, so that a scheduling instruction ticket is formed. The equipment for clicking the graph is attached with ID data (the ID has uniqueness), the sub-state is returned by a remote signaling value, the data is represented as '0', the on-state is returned by the remote signaling value, and the data is represented as '1', so that each command in the command ticket is provided with an identifier and an on-off state remote signaling value. Each scheduling instruction in the scheduling instruction ticket is used for scheduling one power grid device, and comprises an identifier, an initial state and a target state of the power grid device which is requested to be scheduled.
For example, the scheduling instruction ticket face instruction is as follows: instruction 1 "open switch of 10kV jindong line 601", instruction 2 "pull open switch of 10kV jindong line 6012", instruction 3 "pull open switch of 10kV jindong line 6011". The marks of a switch of a 10kV golden east line 601, a switch of 6011 and a switch of 6012 are 666, 777 and 888 respectively, the initial states of the three devices are all closed, and the target states are all separated, then the scheduling instruction ticket data is interpreted as 666+1 → 666+0, 777+1 → 777+0, 888+1 → 888+0.
In step S220, the OCS mobile terminal sends a scheduling instruction ticket to the OCS server.
According to the structure shown in fig. 1, the OCS mobile terminal may establish a connection with the OCS server through the mobile application platform, the external network server, and the internal network switching platform, so that the OCS mobile terminal may send the scheduling instruction ticket to the OCS server.
In step S230, the OCS server transmits the scheduling instruction ticket to the OMS server.
The OMS is responsible for management during sequential control operation of the power grid, so that the OCS server needs to forward the received scheduling instruction ticket to the OMS server.
In step S240, the OMS server sends a scheduling instruction ticket to the OMS scheduling console.
The order control operation is approved and approved by a dispatching desk end which is responsible for carrying out centralized dispatching on the power grid, so that the OMS server sends a dispatching instruction ticket to the OMS dispatching desk end and requests the OMS dispatching desk to carry out auditing on the dispatching instruction ticket.
And step S250, the OMS dispatching desk side carries out auditing treatment on the dispatching instruction ticket, and sends the dispatching instruction ticket passing the auditing to the OMS server after the auditing treatment.
The OMS dispatching desk terminal can audit each dispatching instruction in the received dispatching instruction ticket according to a preset audit flow and an audit standard, or a dispatcher at the OMS dispatching desk terminal can manually audit each dispatching instruction in the dispatching instruction ticket. And if the audit on the scheduling instruction ticket is passed, the OMS scheduling terminal station sends the scheduling instruction ticket passing the audit to the OMS server, and the distributed scheduling sequence control method is continuously executed. If the checking of the scheduling instruction ticket by the OMS scheduling terminal is not passed, it means that the scheduling instruction in the scheduling instruction ticket sent by the OCS mobile terminal is not checked to be passed, and the distributed scheduling sequential control method is terminated.
In step S260, the OMS server sends the scheduling instruction ticket that passes the audit to the OCS server.
Because the OCS server is responsible for sequence control of sequence control operation, the OMS server forwards the scheduling instruction ticket passing the examination to the OCS server, and the OCS server determines the execution sequence of each operation instruction.
Step S270, the OCS server simulates the scheduling instruction tickets that pass the audit, and determines the sequence of at least two scheduling instructions in the scheduling instruction tickets that pass the audit.
The OCS server needs to simulate each scheduling instruction in the scheduling instruction ticket that passes the examination, so as to determine the sequence of at least two scheduling instructions in the scheduling instruction ticket that passes the examination, that is, the execution sequence.
Specifically, the OCS server may simulate at least two scheduling instructions in the approved scheduling instruction ticket into a plurality of device status graphs, and arrange the plurality of device status graphs according to the initial state and the target state according to the operation sequence. As shown in fig. 3, fig. 3 is a flowchart of the OCS server simulating and sequencing the scheduling instructions.
In fig. 3, the OCS system first analyzes the ID, the initial state, and the target state of each scheduling instruction in the audited scheduling instruction ticket, and then the OCS system simulates and generates a plurality of device state images according to the initial state and the target state of the designed operating device, and arranges the device state images according to the operating sequence. And finally, sending the arranged simulation graphs and the scheduling instruction tickets which pass the auditing to the OCS mobile terminal.
For example, the scheduling instruction ticket data is interpreted as 666+1 → 666+0, 777+1 → 777+0, 888+1 → 888+0. From these three devices, six different states, six different patterns can be simulated. And arranging the six graphs according to the operation sequence and the initial and target states, wherein the six graphs are respectively a 10kV Jindong line 601 switch closing graph, a 10kV Jindong line 601 switch opening graph, a 10kV Jindong line 6012 switch closing graph, a 10kV Jindong line 6012 switch opening graph, a 10kV Jindong line 6011 switch closing graph and a 10kV Jindong line 6011 switch opening graph, and as shown in fig. 4, fig. 4 is a simulation graph schematic diagram.
In step S280, the OCS server sends the ordered at least two scheduling instructions to the OCS moving end, so that the OCS moving end sequentially executes the at least two scheduling instructions.
After the OCS server sends the at least two sequenced scheduling instructions to the OCS mobile terminal, a user using the OCS mobile terminal can sequentially execute the at least two scheduling instructions according to the sequencing, thereby completing the distributed scheduling sequence control method.
Specifically, when the OCS server simulates at least two scheduling instructions in the scheduling instruction ticket that passes the audit into a plurality of device state graphs and sequences the scheduling instructions, the OCS server sends the sequenced device state graphs to the OCS mobile terminal, the OCS mobile terminal compares the sequenced device state graphs with the device state graphs on the OCS APP in sequence, and if the device state graphs are matched with the device state graphs, the scheduling instructions corresponding to the device state graphs are executed.
That is, the OCS mobile terminal may sequentially compare the status images of the devices, and execute the scheduling instruction corresponding to the status image of the device after matching is successful. Fig. 5 is a schematic diagram of a sequence control operation execution flow, after the scheduling instruction ticket is started to be executed, N simulation graphs are sequentially compared with a current graph to determine whether the simulation graphs are consistent, if so, an ith instruction (which may be remotely controlled or manually executed by the OCS mobile terminal) corresponding to the scheduling instruction ticket is executed, and if not, a next graph is continuously matched. When the instruction is executed, the Nth simulation graph is sequentially compared with the current graph to judge whether the simulation graph is consistent or not, and after the corresponding instruction of the scheduling instruction ticket is executed, the scheduling instruction ticket automatically and synchronously updates the operation information. After the N simulation graphs are compared in sequence, the complete scheduling instruction ticket is sent to the OMS scheduling station end from the OCS mobile end, the OCS server and the OMS server to be confirmed and filed, and the sequence control process is completed.
For example, for the device status diagram shown in fig. 4, the 1 st command "open 10kV jindong line 601 switch" is executed first. Confirm 10kV gold east 601 switch initial state earlier, compare 1 st bionic figure and this equipment figure at present, judge the sign, divide/close the state unanimously, if inconsistent then compare again, if unanimous can continue the executive instruction, divide/close by APP end remote control equipment (can't the remote control equipment by field operation after, the manual work on APP divides/closes the position), dispatch instruction ticket automatic synchronization updates the operation information, get into 2 nd bionic figure and this equipment figure at present after the execution and compare, judge the sign, divide/close whether unanimous, repeat above-mentioned flow, if compare in the operation period inconsistent, then can't continue the execution. If the comparison is consistent during the operation period, the execution can be continued until all the bionic patterns are compared.
Fig. 6 is a flowchart for comparing the simulation graphs with the device status graphs, and as shown in fig. 6, the simulation graphs are extracted in the order of arrangement and the device identifiers and the separation/combination statuses corresponding to the graphs are extracted, and the device status graphs of the operations are extracted in the order of the scheduling instruction ticket and the device identifiers and the separation/combination statuses corresponding to the graphs are extracted, and then whether the simulation graphs and the device status graphs are consistent or not is compared.
In the distributed scheduling sequential control method provided by this embodiment, the OCS mobile terminal generates a scheduling instruction ticket including at least two scheduling instructions according to a scheduling instruction of a user to the power grid device, the OCS server and the OMS server transmit the scheduling instruction ticket to the OMS scheduling station, after the OMS scheduling station verifies the scheduling instruction ticket, the OCS server simulates the verified scheduling instruction ticket, determines the sequence of at least two scheduling instructions in the verified scheduling instruction ticket, and finally transmits the sequenced at least two scheduling instructions to the OCS mobile terminal, so that the OCS mobile terminal sequentially executes the at least two scheduling instructions, thereby implementing field scheduling and automatic command transmission and reception, and achieving the purpose of sequential control operation of distributed scheduling.
In an embodiment, since a certain operation authority is required for the scheduling operation performed on a part of devices, after the OCS mobile terminal sends the scheduling instruction ticket to the OCS server, the method further includes: the OCS mobile terminal sends a key application to the OCS dispatching station terminal through the OCS server, and the key application is used for requesting the operation authority of the power grid equipment associated with at least two dispatching instructions; then the OCS dispatching station side carries out auditing treatment on the key application, and after the auditing is passed, the OCS service sends the key which has passed the application; and finally, the OCS server sends the key passing the application to the OCS mobile terminal, so that the OCS mobile terminal uses the key passing the application to sequentially execute at least two scheduling instructions.
The key application is automatically initiated by the OCS mobile terminal, and the applied key is associated with the operation authority of the operation device identifier, for example, the key data is interpreted as the operation authority of the remote control and the device separation and combination of the application identifiers 666, 777 and 888. The purpose of applying for the key is to remotely control and place/separate the devices related to the instructions on the OCS mobile terminal, namely to give the OCS mobile terminal the function authority. And the key application is approved by the OCS server to the OCS dispatching station. After the OCS dispatching station side audits the key application, the key association relates to the remote control and the position switching and combining authority of the operating equipment, and the key can open the function authority after the key is approved by a dispatcher. And the OCS dispatching station end sends an approval notice to the OCS mobile end through the OCS server.
In the following description, with reference to scheduling command ticket generation and key application of the OCS mobile terminal, fig. 7 is a flow chart of point diagram ticket generation and key application, where first, point diagram ticket generation is executed at the OCS mobile terminal, then, the OCS mobile terminal is switched to a simulation state in a power grid connection diagram, and then, according to a planned operation task requirement and an operation sequence, an initial state and a target state are determined correspondingly one by one point diagram. And then obtaining a scheduling instruction ticket, automatically initiating a key application according to the scheduling instruction ticket, finally respectively sending the scheduling instruction ticket to an OMS scheduling terminal for auditing through an OMS server, and sending the key application to an OCS scheduling terminal for auditing.
