It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0035] Combination Figures 1 to 5 As shown, according to a specific embodiment of the present invention, an automatic acceptance system based on a power grid model is provided.

[0036] Specifically, Figure 1 , Figure 2 As shown, the automatic acceptance system based on the power grid model includes: a control main station 1, which is used to send control signals; multiple communication modules 2, which are electrically connected to the control main station 1; multiple transformer substations 3, which are arranged in a one-to-one correspondence with the multiple transformer substations 3, and each transformer substation 3 is connected to the control main station 1 through the corresponding communication module 2. The transformer substation 3 generates a topology image and a remote control acceptance sequence table based on the control signal, wherein the topology image is used to represent the connection relationship, position and status of the terminal device 33; and the transformer substation 3 is used to detect whether the status of the terminal device 33 is normal; the control main station 1 generates remote control information based on the topology image and the remote control acceptance sequence table, and the transformer substation 3 generates remote control instructions based on the remote control information, and the remote control instructions are used to control the terminal device 33 of the transformer substation 3 to perform closing and opening actions.

[0037] In this embodiment, the control signal sent by the control master station 1 is used to establish communication with multiple communication modules 2, so that each transformer substation 3 can automatically generate a topological image reflecting the connection relationship, position and status of the power grid equipment based on the control signal, as well as a remote control acceptance sequence table for guiding remote control operation, thereby realizing dynamic adaptation to the power grid model and real-time monitoring of the equipment status. The remote control information generated by the control master station 1 based on the topological image and the remote control acceptance sequence table not only guides the transformer substation 3 to generate accurate remote control instructions, but also ensures the matching of the instructions with the actual status of the equipment, which enables the transformer substation 3 to accurately control the terminal equipment 33 under it to perform closing and opening actions, thereby realizing the automation and high-precision verification of remote control operation. This process significantly reduces manual intervention and avoids errors caused by improper manual operation, while improving the efficiency and reliability of the acceptance of the remote control function of the power grid equipment, and ensuring the safety and stability of the power grid operation. In addition, the multiple communication modules 2 in the system design are set one-to-one with the transformer substation 3, which enhances the flexibility of remote control and the overall performance of the system.

[0038] It should be noted that the terminal equipment 33 of the present application includes a circuit breaker, an isolating switch, a grounding switch, etc. The circuit breaker, the isolating switch, and the grounding switch all include a remote mode and a local mode.

[0039] In some optional embodiments, the present invention can send device remote control information to the configuration host 32 in a single step or continuously by regulating the main station 1, and the configuration host 32 controls the corresponding device to respond to the remote control.

[0040] like Figure 2 As shown, each transformer substation 3 includes: an equipment status verification module 34, the equipment status verification module 34 is electrically connected to the terminal equipment 33, and the equipment status verification module 34 is electrically connected to the control main station 1, the equipment status verification module 34 is used to determine whether the status of the terminal equipment 33 is normal, and when it is determined that the status of the terminal equipment 33 is abnormal, the equipment status verification module 34 is used to detect the fault point location and fault number of the terminal equipment 33.

[0041] Specifically, each substation 3 integrates an equipment status verification module 34, which can monitor and analyze the operating status of the equipment in real time through electrical connection with the terminal equipment 33, ensuring the timeliness and accuracy of the equipment status. When the equipment status verification module 34 identifies that the status of the terminal equipment 33 deviates from normal, it can quickly locate the fault point and determine the fault number. This function greatly improves the efficiency and accuracy of fault response. At the same time, the electrical connection between the equipment status verification module 34 and the control master station 1 ensures the instant upload of fault information, provides real-time fault data for the control master station, supports it in making timely and accurate dispatching decisions, avoids the further spread of faults, and ensures the safety and stability of power grid operation.

[0042] Furthermore, each transformer substation 3 includes: a network interface module 31, which is electrically connected to the communication module 2; a configuration host 32, which is electrically connected to the network interface module 31, and the configuration host 32 generates a power grid model based on the control signal, and generates a topology image according to the power grid model, and generates a remote control acceptance sequence list according to the topology image, and uploads the topology image and the remote control acceptance sequence list to the control master station 1, wherein the topology image is used to represent the connection relationship, position and status of the terminal device 33.

[0043] Specifically, by configuring the host to automatically generate a power grid model, a topology image, and a remote control acceptance sequence list, real-time monitoring of the power grid equipment status and automated verification of remote control operations are achieved.

[0044] In some optional embodiments, the network interface module 31 uses an RJ-45 interface, an SPF interface, an optical fiber interface, and the like.

[0045] like Figure 3 As shown, the configuration host 32 includes: an OCS system 321, the OCS system 321 is used to enter the device information of the terminal device 33, wherein the device information at least includes: a device information number, a device installation location and a device operating parameter; a device information acquisition module 322, the device information acquisition module 322 is electrically connected to the OCS system 321, and the device information acquisition module 322 generates a device information table based on the device information.

[0046] Specifically, the OCS system is an online control system (Online Control System). The OCS system usually integrates data acquisition and monitoring system functions, and can collect a large amount of data in the power network in real time, including but not limited to equipment status information, voltage, current, power and other telemetry data.

[0047] In this embodiment, the combination of the OCS system 321 and the equipment information acquisition module 322 realizes the automated processing and efficient integration of equipment information, provides a data basis for the construction of power grid models, equipment status monitoring and remote control acceptance, and records equipment operating parameters, especially detailed descriptions of equipment control parameters, which provides data support for generating a remote control acceptance sequence table, thereby realizing automated verification of equipment remote control operations and improving the accuracy and safety of remote control operations.

[0048] Furthermore, the configuration host 32 includes: a power grid GIM model generation module 323, the power grid GIM model generation module 323 is electrically connected to the device information acquisition module 322, and the power grid GIM model generation module 323 is used to receive the device information table and generate a power grid model.

[0049] The above-mentioned power grid model is a standardized data model used to describe the structure and operating status of the power system. It not only includes the physical connection relationship of each device in the power grid, but also includes the attribute information of the device, such as device type, installation location, operating parameters, etc. The GIM model is usually used for the exchange and sharing of power grid data in the automation system. It can provide the topology information, device status and operating parameters of the power grid, so that different systems can understand and use the power grid data and work together. For example, the power grid dispatching system, automation monitoring system, fault diagnosis system, etc. can exchange data and integrate functions based on the GIM model.

[0050] Furthermore, the configuration host 32 includes: a topology image generation module 324, which is electrically connected to the power grid GIM model generation module 323, and the topology image generation module 324 generates a topology image of the terminal device 33 based on the power grid GIM model, and the topology image is used to represent the connection relationship, position and status of the terminal device 33.

[0051] In this embodiment, Figure 5 The topology image of the present invention not only shows the physical connection of the equipment, but also can reflect the status of the equipment in real time, such as whether the equipment is online, whether the operating parameters are normal, etc. When the equipment status changes, such as the opening and closing of the circuit breaker, the topology image can be updated in real time and quickly fed back to the control center to ensure the timeliness and accuracy of scheduling and control decisions.

[0052] Furthermore, the configuration host 32 includes a remote control acceptance sequence generation module 326 , which is electrically connected to the topology image generation module 324 , and generates a remote control acceptance sequence table based on the topology image.

[0053] The above-mentioned remote control acceptance sequence table includes equipment identification, operation instructions, acceptance sequence, expected status, and acceptance result record.

[0054] Each entry corresponds to a terminal device, and the entry contains the unique identifier of the device, such as the device number, to facilitate the system to identify and operate the target device. For each device, the list contains one or more remote control operation instructions, such as "close", "open", "adjust parameters", etc. These operations are intended to verify whether the device responds correctly to the remote control signal. The remote control operation is performed in a certain order, which may be based on the connection relationship and physical location of the devices in the topology image to ensure the continuity and logic of the operation and avoid grid problems that may be caused by operating adjacent or related devices at the same time. After each operation instruction, there is usually a description of the expected state of the device, such as whether the device should be in the "closed" state or the "open" state after the operation. This helps to quickly determine whether the device state meets expectations after the operation, thereby evaluating the correctness of the remote control function. The remote control acceptance sequence list also includes a record of each operation result, including whether the operation is successful, the actual state of the device and the comparison with the expected state.

[0055] By generating and using the remote control acceptance sequence table, the automation level of remote control testing is greatly improved, the errors caused by manual operation are reduced, and the integrity and accuracy of the remote control function in the system are ensured.

[0056] Furthermore, the configuration host 32 also includes: a topology image change module 325, which is electrically connected to the OCS system 321, the topology image generation module 324 and the remote control acceptance sequence generation module 326. The topology image change module 325 is used to receive updated device information and topology images in the OCS system 321 to change the topology image, obtain the changed topology image, and upload the changed topology image to the remote control acceptance sequence generation module 326. The remote control acceptance sequence generation module 326 generates an updated remote control acceptance sequence table based on the updated topology image.

[0057] Specifically, in the power grid, device information and connection relationships may change due to the addition of new devices, removal of devices, or changes in device location. The topology image change module 325 can receive updated device information and topology images in the OCS system 321, and reflect these changes in a timely manner to ensure that the topology image in the system is always consistent with the actual situation of the power grid. The updated topology image must ensure the accuracy of device information, including the physical location of the device, connection relationship, and device status. An accurate topology image can guide the remote control acceptance sequence generation module 326 to generate a more accurate remote control acceptance sequence table, ensuring that each remote control operation in the automated test points to the correct device, avoiding misoperation, and improving the accuracy of testing and acceptance.

[0058] Furthermore, the device status verification module 34 includes: a sensor module, the sensor module is used to be set on the terminal device 33, and the sensor module is used to collect the temperature, current and voltage of the terminal device 33; a judgment module, the judgment module is used to judge whether the temperature, current and voltage are within a preset range; a determination module, when it is determined that the temperature, current or voltage is not within the preset range, the terminal device 33 has a fault; an inspection robot 341, when it is determined that the temperature, current, and voltage are within the preset range, the inspection robot 341 is used to detect the numbering data information of the terminal device 33, and transmit the numbering data information to the OCS system 321.

[0059] Specifically, the equipment status verification module 34 monitors the temperature, current and voltage of the terminal equipment 33 in real time by integrating the sensor module, judgment module and determination module, and can quickly identify whether the equipment is in normal working condition. If any parameter is found to exceed the preset safety range, the equipment is immediately judged to be faulty, thereby achieving early warning and preventive maintenance, significantly reducing the impact of equipment failure on power grid operation. In addition, when the operating parameters of the equipment are within the normal range, the inspection robot 341 automatically intervenes to detect and upload the terminal equipment number data information to the OCS system 321. This automated process not only reduces the workload and potential errors of manual inspections, but also improves the accuracy and timeliness of data entry.

[0060] Furthermore, the control master station 1 includes: a control master station front-end machine 11, which is electrically connected to the equipment status verification module 34 and is used to send control signals; a scheduling network 12, which exchanges information with the control master station front-end machine 11 and is electrically connected to the communication module 2; an alarm module 13, which is electrically connected to the control master station front-end machine 11 and is used to issue an alarm; and a touch screen 14, which is electrically connected to the control master station front-end machine 11 and is used to display a topology image and a remote control acceptance sequence list.

[0061] Specifically, the control master station front-end 11 serves as a control center and is electrically connected to the equipment status verification module 34. It can accurately send control signals to realize remote operations, such as closing and opening of equipment, etc., which greatly reduces manual intervention and improves the accuracy and response speed of operations. The dispatching network 12 ensures the smooth transmission of information between the control master station and the substation, enables real-time feedback of control signals and equipment status, and enhances the continuity and stability of the system. The alarm module 13 immediately triggers an alarm when the equipment status is abnormal or the remote control operation fails, providing key support for early identification and rapid response of faults, and effectively preventing potential power grid safety issues. As a human-computer interaction interface, the touch screen 14 not only intuitively displays the topological image of the power grid, but also presents the remote control acceptance sequence list, allowing the operator to master the equipment layout and control process, greatly simplifying the complexity of operation and improving the user experience of automated control.

[0062] In some optional embodiments, a method for generating a remote control acceptance sequence table is as follows: in a topological image, devices of the same type are represented by the same letter and sub-letter, and devices of the same type are numbered from left to right and from top to bottom; a prompt light is provided next to each terminal device 33, and the prompt light is used to display the implementation status of the device.

[0063] When the device is in normal state, the corresponding indicator light is green.

[0064] When the device's implementation status is abnormal, the corresponding indicator light flashes red.

[0065] The controller sends a control signal through the front-end processor 11 of the control master station, and the control signal is sent to the configuration host 32 through the dispatching network 12, the communication module 2, and the network interface module 31.

[0066] First, the host 32 is configured to control the corresponding device of the terminal device 33 to switch from the local mode to the remote mode, and then the host 32 is configured to control the terminal device 33 from closing to opening (or from opening to closing), and the device status verification module 34 detects the implementation status of the terminal device 33 and uploads the status of the terminal device 33 to the control main station front-end machine 11; then, the control main station front-end machine 11 receives the status of the terminal device 33 and displays the implementation status of the terminal device 33 in the topology image, and then displays the topology image through the touch screen 14.

[0067] When the device is in normal state, the corresponding device indicator light is green.

[0068] When the implementation status of the device is abnormal, the corresponding device prompt light flashes red, and an alarm is sent to the device status verification module 34 through the alarm module 13.

[0069] Then, the device state checking module 34 detects the location of the fault point when the device's implementation state is abnormal.

[0070] like Figure 4 As shown, the equipment status verification module 34 includes an inspection robot 341, a temperature sensor 342, a current sensor 343, and a voltage sensor 344. The inspection robot 341 is used to detect the serial number data information of the terminal equipment 33 inside the power plant. The temperature sensor 342, the current sensor 343, and the voltage sensor 344 are all fixedly installed on the terminal equipment 33 and are used to collect the temperature, current, and voltage of the terminal equipment 33. The inspection robot 341, the temperature sensor 342, the current sensor 343, and the voltage sensor 344 are all electrically connected to the configuration host 32.

[0071] According to another aspect of the present invention, a method for the device status verification module 34 to determine a fault point is provided, the method comprising the following steps:

[0072] Step S10: The temperature sensor 342, the current sensor 343, and the voltage sensor 344 detect the temperature, current, and voltage data information of the terminal device 33 corresponding to the fault and upload them to the OCS system 321. If the OCS system 321 detects that any one of the temperature, current, and voltage data of the terminal device 33 is not within the deviation range from the value set in the system, it is determined that the fault point is the terminal device 33 itself.

[0073] Step S12: If the configuration host 32 detects that the temperature, current and voltage data of the terminal device 33 are all within the deviation range of the system set values, the inspection robot 341 will take a picture of the number on the corresponding device and upload it to the OCS system 321. The OCS system 321 receives the device number and compares it with the device number stored in the system.

[0074] Step S13: If the device number stored in the system does not match the number on the corresponding device, the OCS system 321 will update the number on the corresponding device to the topology image change module 325, change the topology image of the device connection in the topology image change module 325, regenerate the remote control sequence acceptance table in the remote control acceptance sequence generation module 326, and then upload the regenerated topology image and remote control sequence acceptance table to the control master station front-end machine 11.

[0075] Step S14: If the device number stored in the system matches the number on the corresponding device, the control and regulation master station front-end machine 11 resends the device remote control signal. If the corresponding device prompt light shows green, it means that the control signal of the control and regulation master station front-end machine 11 has not been sent.

[0076] Step S15: If the corresponding device prompt light is still flashing red, the control master station front-end processor 11 notifies the relevant staff to come to the site to use the local mode to turn on the corresponding device.

[0077] Step S16: If the corresponding device prompt light is displayed in green, it means that the mode switching of the terminal device 33 has failed.

[0078] Step S17: If the corresponding device prompt light is still flashing red, the control master station front-end processor 11 notifies the maintenance personnel to come to the site to further repair the equipment.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application.
