Description

Technical Field

[0001] The invention relates to the field of automatic control of electric power systems, in particular to a one-button sequential control knife double confirmation simulation acceptance device. Background Art

[0002] As substations continue to develop in the direction of intelligence and informatization, the operation of power equipment in the station has gradually adopted a one-key sequential control operation mode instead of the manual on-site operation mode. Therefore, remote control of primary equipment in substations has basically been realized, such as a method, device, equipment and medium for automatic acceptance of substation one-key sequential control without power outages with patent number CN119051255A, wherein the method includes obtaining a one-key sequential control operation ticket of a target substation sequential control host, performing semantic analysis on the one-key sequential control operation ticket based on Alibaba's semantic segmentation model for natural language processing to obtain a first key field data set; statically verifying the first key field data set with the underlying preset database of the sequential control host, and obtaining a first key field data set based on the static verification. A key field data set is used to construct a sequential control instruction set; the automation configuration file information of the target substation is parsed and simulation interval parameters are generated, and a virtual simulation one-button sequential control test system is constructed according to the parsing results and the simulation interval parameters; each instruction in the sequential control instruction set is input into the one-button sequential control test system in sequence for logic verification, and the one-button sequential control acceptance of the target substation is realized according to the result of the logic verification. While realizing the remote control of the substation equipment, the efficiency of the one-button sequential control acceptance is improved. However, when the one-button sequential control test system constructed as above is used for acceptance, the actual state change of the circuit is not taken into account. When the circuit state changes, that is, the line switch and the bus switch double confirm the installation and debugging at the same time, it is difficult to fully verify the one-button sequential control. Summary of the invention

[0003] In view of the problem that it is difficult to fully verify the one-button sequential control when the line switch and bus switch are installed and debugged at the same time with double confirmation in the prior art, the present invention provides a one-button sequential control switch double confirmation simulation acceptance device, which simulates the opening and closing action of the switch according to the one-button sequential control command, circuit state and interval type through the switch opening and closing simulation module. When the installation and debugging of the line switch or bus switch causes the sequential control ticket related to the line switch or bus switch to be unable to be verified, the switch opening and closing simulation module simulates the opening and closing of the line switch or bus switch. After the simulation, the generated response signal is uploaded to the one-button sequential control host, thereby realizing the verification of the sequential control ticket related to the line switch or bus switch. The problem that it is difficult to fully verify the one-button sequential control when the line switch and bus switch are installed and debugged at the same time with double confirmation is solved, thereby improving the reliability of the one-button sequential control and ensuring the safe and stable operation of the power grid.

[0004] In order to solve the above technical problems, the present invention provides a one-button sequential control knife double confirmation simulation acceptance device, including a communication control module and a knife opening and closing simulation module. The communication control module is electrically connected to the knife opening and closing simulation module, and is used to receive the one-button sequential control command and transmit the one-button sequential control command to the knife opening and closing simulation module. The knife opening and closing simulation module is used to simulate the opening and closing action of the knife according to the one-button sequential control command, circuit status and interval type, and generate a response signal after the simulation is completed, and upload the response signal to the one-button sequential control host.

[0005] After adopting the above technical solution, the present invention has the following advantages: Considering that the line switch or bus switch cannot work normally during the installation and commissioning of the line switch or bus switch, the control tickets related to the line switch or bus switch cannot be verified. When the installation and commissioning are completed, the line operates normally. Since the line is energized, it is more difficult to verify the control tickets. Therefore, the opening and closing of the line switch or bus switch is simulated by the switch opening and closing simulation module. When the installation and commissioning of the line switch or bus switch causes the control tickets related to the line switch or bus switch to be unable to be verified, the opening and closing of the line switch or bus switch is simulated by the switch opening and closing simulation module. After the simulation, the generated response signal is uploaded to the one-key control host, thereby realizing the verification of the control tickets related to the line switch or bus switch, thereby improving the comprehensiveness of the one-key control verification and the reliability of the one-key control, and ensuring the safe and stable operation of the power grid; By using the knife opening and closing simulation module to simulate the knife action under various circuit states and interval types, the flexibility and applicability of the device are improved; In some actual acceptance operations, in order to ensure the safety of acceptance, a power outage operation is required. The switch opening and closing simulation module in this device can simulate the power outage operation and perform acceptance without power outage, thereby improving the availability and stability of the power grid; The knife opening and closing simulation module simulates the opening and closing action of the knife, and can verify the one-key sequential control command without actually operating the knife, which significantly shortens the acceptance time and thus significantly improves the acceptance efficiency; The problem of difficulty in fully verifying one-button sequential control during the simultaneous installation and debugging of the line switch and bus switch has been solved.

[0012] Considering that when the second auxiliary bus is in working condition and the second positive bus is being repaired, the main bus auxiliary mother switch cannot be operated to ensure the safety of equipment and personnel. Therefore, the action of the main bus auxiliary mother switch is simulated by the switch opening and closing simulation module. Considering that when the second positive bus is in working condition and the main bus is being repaired, the main bus main mother switch cannot be operated to ensure the safety of equipment and personnel.

[0014] Considering that when the single bus is in working condition and the second interval line is under maintenance, in order to ensure the safety of equipment and personnel, the interval bus switch cannot be operated. Therefore, the action of the interval bus switch is simulated by the switch opening and closing simulation module. Considering that when the single bus is not in working condition and the second interval line is energized, in order to ensure the safety of equipment and personnel, the interval line switch cannot be operated. Therefore, the action of the interval line switch is simulated by the switch opening and closing simulation module.

[0024] Embodiment 1: like Figure 1 As shown, a one-button sequential control knife double confirmation simulation acceptance device includes a communication control module and a knife opening and closing simulation module. The communication control module is electrically connected to the knife opening and closing simulation module, and is used to receive a one-button sequential control command and transmit the one-button sequential control command to the knife opening and closing simulation module. The knife opening and closing simulation module is used to simulate the opening and closing action of the knife according to the one-button sequential control command, circuit status and interval type, and generate a response signal after the simulation is completed, and upload the response signal to the one-button sequential control host.

[0025] In this embodiment, the one-key sequential control knife double confirmation simulation acceptance device is suitable for use in single-interval maintenance, when the equipment is not fully installed or the equipment is not fully maintained. The one-key sequential control knife double confirmation simulation acceptance device consists of a communication control module and three sets of knife opening and closing simulation modules. The communication control module, i.e., the communication control device, is responsible for receiving the one-key sequential control command, i.e., transmission control information, transmitting the one-key sequential control command downward, and converting the TCP protocol command received through the network cable into a 485 protocol output. The three sets of knife opening and closing simulation modules are connected in parallel to simulate the opening and closing actions of knife A, knife B, and knife C respectively, and output the status signals of the three knives, i.e., the response signals. By simulating the opening and closing action of a knife that is not working properly, the verification of the sequential control ticket related to the knife that is not working properly is realized, thereby improving the comprehensiveness of the one-key sequential control verification and the reliability of the one-key sequential control, and ensuring the safe and stable operation of the power grid. By using the knife opening and closing simulation module to simulate the knife action under various circuit states and interval types, while improving the flexibility and applicability of the device, the comprehensiveness of the one-key sequential control verification and the reliability of the one-key sequential control are further improved; at the same time, in some actual acceptance operations, in order to ensure the safety of acceptance, a power outage operation is required, and the knife opening and closing simulation module in this device can simulate the power outage operation, and acceptance is carried out without power outage, thereby improving the availability and stability of the power grid; By simulating the opening and closing action of the knife through the knife opening and closing simulation module, the one-key sequential control command can be verified without actually operating the knife, which significantly shortens the acceptance time and thus significantly improves the acceptance efficiency.

[0026] The interval types include at least double-mother wiring line intervals, double-mother wiring bus-coupler intervals and single-mother wiring line intervals.

[0027] In this embodiment, the double-mother wiring line interval includes the double-mother wiring main transformer interval and the double-mother wiring line interval, and the interval types also include the single-mother wiring main transformer, the single-mother wiring bus branch, the internal bridge wiring line and the line transformer group wiring. By using the knife opening and closing simulation module to simulate the knife action under various bay types, the flexibility and applicability of the device are improved, and the comprehensiveness of the one-button sequential control verification and the reliability of the one-button sequential control are further improved.

[0028] The simulating the opening and closing action of the switch according to the one-button sequential control command, circuit state and interval type includes: When the bay type is a double-mother wiring line bay, the first positive bus or the first bay line or switch is under maintenance, and the one-button sequential control command is executed to close the bay secondary bus switch, the knife opening and closing simulation module is used to simulate the closing action of the bay secondary bus switch; when the bay type is a double-mother wiring line bay, the first secondary bus or the first bay line or switch is under maintenance, and the one-button sequential control command is executed to close the bay positive bus switch, the knife opening and closing simulation module is used to simulate the closing action of the bay positive bus switch.

[0029] The simulation of the opening and closing action of the switch according to the one-button sequential control command, circuit status and interval type also includes: when the interval type is a double-bus connection line interval, the first positive bus and the first secondary bus are in working condition, the first interval line is inspected and maintained, and the one-button sequential control command is executed to close the interval secondary bus switch and the interval positive bus switch, the switch opening and closing simulation module is used to simulate the closing action of the interval secondary bus switch and the interval positive bus switch.

[0030] In this embodiment, three sets of knife opening and closing simulation modules, i.e., knife simulation devices, are used, in which A represents the interval main mother knife, B represents the interval auxiliary mother knife, and C represents the interval line knife. When the main bus or interval line or switch is under maintenance, the interval auxiliary mother knife cannot be operated, otherwise it will cause power supply and cause equipment and personal safety. At this time, device B is used to replace the simulated interval auxiliary mother knife. When the one-key sequential control command is executed to close the auxiliary mother knife, the auxiliary mother knife closing action is executed by B, and a response signal, i.e., a closing signal, is triggered and sent to the one-key sequential control host. The one-key sequential control host receives the response signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful. Similarly, when the secondary busbar or interval line or switch is under maintenance, the interval main mother switch cannot be operated, otherwise it will cause power transmission and cause equipment and personal safety. At this time, device A is used to replace the simulated interval main mother switch. When the one-key sequential control command is executed to close the main mother switch, device A simulates the closing of the device and triggers a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the response signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful; When both the main and auxiliary mother switches are not out of service and the line is equipped with switches and line maintenance, the main mother switch and auxiliary mother switch of the interval cannot be operated. At this time, device A is used to simulate the main mother switch signal of the interval, and device B is used to simulate the auxiliary mother switch signal of the interval. When the one-key sequential control command is executed to close the corresponding switch, device A and device B are used to simulate the device closing and trigger a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the simulated signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful; The current maintenance status has the one-button sequential control test, but the double confirmation device is not fully installed and is temporarily not capable of cooperating with the one-button sequential control test. At this time, the knife opening and closing simulation module needs to be used to replace the signal trigger and cooperate with the verification of the one-button sequential control ticket; By using the knife opening and closing simulation module to simulate the knife action under various circuit states and interval types, the flexibility and applicability of the device are improved while further improving the comprehensiveness of the one-button sequential control verification and the reliability of the one-button sequential control. At the same time, the one-button sequential control command can be verified without actually operating the knife, which significantly shortens the acceptance time and thus significantly improves the acceptance efficiency.

[0031] The simulating the opening and closing action of the switch according to the one-button sequential control command, circuit state and interval type includes: When the bay type is a double-bus connection bus coupler bay, the second secondary bus is in working condition, the second positive bus is being overhauled, and the one-button sequential control command is executed to close the bus coupler secondary bus switch, the knife opening and closing simulation module is used to simulate the closing action of the bus coupler secondary bus switch; when the bay type is a double-bus connection bus coupler bay, the second positive bus is in working condition, the second secondary bus is being overhauled, and the one-button sequential control command is executed to close the bus coupler positive bus switch, the knife opening and closing simulation module is used to simulate the closing action of the bus coupler positive bus switch.

[0032] In this embodiment, device A represents the main mother switch of the bus coupling interval, device B represents the auxiliary mother switch of the bus coupling interval, and device C represents the spare. When the main mother is under maintenance and the auxiliary mother is in operation, the auxiliary mother switch of the bus coupling cannot be operated, otherwise it will cause power transmission and cause equipment and personal safety. At this time, device B is used to replace the simulated auxiliary mother switch of the bus coupling. When the one-key sequential control command is executed to close the auxiliary mother switch, device B simulates the closing of the auxiliary mother switch of the bus coupling and triggers a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the response signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful. During the maintenance of the auxiliary mother and the operation of the main mother, the main mother switch of the mother couple cannot be operated, otherwise it will cause power transmission and cause equipment and personal safety. At this time, device A is used to replace the simulated main mother switch of the mother couple. When the one-key sequential control command is executed to close the auxiliary mother switch, device A simulates the closing of the main mother switch of the mother couple and triggers a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the response signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful; By using the knife opening and closing simulation module to simulate the knife action under various circuit states and interval types, the flexibility and applicability of the device are improved while further improving the comprehensiveness of the one-button sequential control verification and the reliability of the one-button sequential control. At the same time, the one-button sequential control command can be verified without actually operating the knife, which significantly shortens the acceptance time and thus significantly improves the acceptance efficiency. In some actual acceptance operations, in order to ensure the safety of acceptance, power outage operations are required. The knife opening and closing simulation module in this device can simulate power outage operations and perform acceptance without power outages, thereby improving the availability and stability of the power grid.

[0034] In this embodiment, device A represents the interval bus switch, device B represents the spare, and device C represents the interval line switch. When the bus is in operation and only the interval switch and line are under maintenance, the interval bus switch cannot be operated, otherwise it will cause power supply and cause equipment and personal safety. At this time, device A is used to simulate the interval bus switch. When the one-key sequential control command is executed to close the auxiliary bus switch, device A is used to simulate the closing of the interval bus switch and trigger a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the signal. The response signal indicates that the operation is successful and the one-key sequential control ticket verification is successful; when the bus is out of service and the line is energized, the line switch cannot be operated, otherwise it will cause power transmission and cause equipment and personal safety. At this time, device C is used to simulate the interval line switch. When the one-key sequential control command is executed to close the interval line switch, device C is used to simulate the interval line switch closing and trigger a response signal, i.e., a closing signal, which is sent to the one-key sequential control host. The one-key sequential control host receives the response signal, indicating that the operation is successful and the one-key sequential control ticket verification is successful; When the conditions for a complete one-button sequential control test are not available on site, the knife opening and closing simulation module can be used to simulate the double confirmation signal of the one-button sequential control knife to verify the one-button sequential control ticket, which is conducive to speeding up the one-button sequential control construction work.

[0035] By using the knife opening and closing simulation module to simulate the knife action under various circuit states and interval types, the flexibility and applicability of the device are improved while further improving the comprehensiveness of the one-button sequential control verification and the reliability of the one-button sequential control. At the same time, the one-button sequential control command can be verified without actually operating the knife, which significantly shortens the acceptance time and thus significantly improves the acceptance efficiency. In some actual acceptance operations, in order to ensure the safety of acceptance, power outage operations are required. The knife opening and closing simulation module in this device can simulate power outage operations and perform acceptance without power outages, thereby improving the availability and stability of the power grid.
