TECHNICAL FIELD

[0001] The present application relates to the technical field of power grid operation method, in particular to a regional intelligent operation control method and system based on block chain. BACKGROUND

[0002] The whole formed by various voltage substations and power transmission and distribution lines in the power system is called a power grid. It includes three units: power transformation, power transmission and power distribution. The task of the power grid is to transport and distribute electric energy and change voltage. Power grid business is the leading industry and main business of power grid companies. The development direction is to build an energy internet and act as the chain leader of the power industry chain. Normal service of the power grid is the backbone of energy security and economic and social development.

[0003] In the power system and power grid service, the safe operation of power grid equipment is an important link to ensure production safety and plays a decisive role. However, there are problems in the current power grid equipment operation method. Specifically, the traditional recording method of primary and secondary equipment state relies on manual recording, which leads to low efficiency and low accuracy. On the other hand, due to manual operation, workers without permission can operate, which easily leads to safety problems. In addition, during actual operation, maintenance personnel act as both the actual executor of operation instructions and the data recording personnel of operation results. If the guardian fails to monitor, it is difficult to discover the misoperation in time, which easily leads to power accidents, causing serious impact on personal, power grid and equipment safety, resulting in low safety performance and inaccurate operation. SUMMARY

[0004] Therefore, it is necessary to provide a regional intelligent operation control method based on block chain, which can improve the operation accuracy and safety performance.

[0005] It is also necessary to provide a regional intelligent operation control system based on block chain, which can improve the operation accuracy and safety performance.

[0006] A regional intelligent operation control method based on block chain, the method comprises:

[0007] Step S100: obtaining the current personnel DID digital identity input by the current operator based on the preset block chain identification module, and performing permission authentication on the current personnel DID digital identity. When the permission authentication is passed, the current operation demand data of the current operator is obtained, wherein the current operation demand data includes the current operation step and the required power grid equipment for the current operation;

[0008] Step S200: Obtain the demand device positioning information of each power grid device required for the current operation, and collect the current state data of each power grid device required for the current operation based on the preset information collection module according to the demand device positioning information;

[0009] Step S300: Determine the usability of each power grid device required for the current operation according to the current state data, and when it is determined that each power grid device required for the current operation is in a usable state, obtain the simulation operation verification expression of the current operator, and generate a simulation start instruction according to the simulation operation verification expression;

[0010] Step S400: According to the simulation start instruction, control the virtual power grid device corresponding to the current operation required power grid device to perform simulation operation according to the current operation step, and generate simulation operation result, according to the simulation operation result, generate operation display tutorial, and send the operation display tutorial to the preset information receiving terminal of the current operator, in order to guide the current operator to control the current operation required power grid device.

[0011] A regional intelligent operation management and control system based on blockchain, comprising:

[0012] The permission authentication module is configured to obtain the current personnel DID digital identity input by the current operator based on the preset blockchain identification module, and perform permission authentication on the current personnel DID digital identity. When the permission authentication is passed, the current operation demand data of the current operator is obtained, wherein the current operation demand data includes the current operation step and the current operation required power grid device.

[0013] The state determination module is configured to obtain the demand device positioning information of each power grid device required for the current operation, and collect the current state data of each power grid device required for the current operation based on the preset information collection module according to the demand device positioning information;

[0014] The simulation operation module is configured to determine the usability of each power grid device required for the current operation according to the current state data, and when it is determined that each power grid device required for the current operation is in a usable state, obtain the simulation operation verification expression of the current operator, and generate a simulation start instruction according to the simulation operation verification expression;

[0015] The operation instruction module is configured to control the virtual power grid device corresponding to the current operation required power grid device to perform simulation operation according to the simulation start instruction and the current operation step, and generate simulation operation result, according to the simulation operation result, generate operation display tutorial, and send the operation display tutorial to the preset information receiving terminal of the current operator, in order to guide the current operator to control the current operation required power grid device.

[0016] A computer device includes a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the steps described in the blockchain-based regional intelligent operation control method.

[0017] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps described in the blockchain-based regional smart operation control method.

[0018] In the aforementioned blockchain-based regional intelligent operation control method and system, to accurately obtain user identity and perform authentication, an authorization step is set up. Specifically, based on a preset blockchain identification module, the current operator's DID digital identity is obtained, and authorization is performed on the current operator's DID digital identity. When authorization is successful, the current operator's current operation requirement data is obtained. Next, to accurately simulate according to actual needs, it is necessary to first determine whether the actual equipment can be used normally. Before this, the specific location of each required device needs to be obtained. Therefore, the location information of each required power grid device for the current operation is obtained, and the current status data of each required power grid device for the current operation is collected based on the location information of the required devices using a preset information collection module. Next, to further accurately determine whether each device is usable, the usability of each required power grid device for the current operation is determined based on the current status data. Only when all required power grid devices for the current operation are determined to be usable will the operation continue, that is, the simulated operation verification expression of the current operator is obtained, and the operation is performed based on the current operation requirement data. The simulation operation verification process generates a simulation start command. Finally, to improve safety and the operability of subsequent operations, the virtual power grid equipment corresponding to the power grid equipment required for the current operation is controlled according to the simulation start command and the current operation steps to perform a simulation operation, generating simulation operation results. Then, an operation demonstration tutorial is generated based on the simulation operation results and sent to the current operator's preset information receiving terminal to guide the current operator in operating the power grid equipment required for the current operation. This provides guidance to the current operator and improves the safety of the operation process. Therefore, this invention first obtains the personnel's identity and performs identity authentication, obtaining a digital identity (DID) based on blockchain technology. This ensures the reliability and accuracy of identity authentication. Furthermore, by utilizing blockchain, confidential operation in power grid control is achieved. Simultaneously, the blockchain identification module can retain and record operation records, and the immutability of blockchain technology enhances confidentiality and data authenticity, thus providing stable data support for subsequent record traceability of power grid operations.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0029] In one embodiment, an application scenario for a blockchain-based regional intelligent operation and control method is provided. This application scenario includes a data processing terminal, which is pre-equipped with a blockchain identification module. The data processing terminal is used to obtain the current operator's DID digital identity input by the current operator based on the pre-equipped blockchain identification module, and to perform authorization authentication on the current operator's DID digital identity. When authorization authentication is successful, the terminal obtains the current operator's current operation requirement data, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation; it also obtains the required equipment location information for each of the required power grid equipment, and collects information based on the required equipment location information using a pre-equipped information collection module. The system collects current status data of the required power grid equipment; determines the usability of each required power grid equipment based on the current status data; when all required power grid equipment are determined to be usable, it obtains the simulated operation verification expression of the current operator and generates a simulated start command based on the simulated operation verification expression; according to the simulated start command, it controls the virtual power grid equipment corresponding to the required power grid equipment to perform simulated operation according to the current operation steps, generates simulated operation results, generates an operation demonstration tutorial based on the simulated operation results, and sends the operation demonstration tutorial to the current operator's preset information receiving terminal to guide the current operator in operating the required power grid equipment.

[0030] In this embodiment, the data processing terminal includes various personal computers, laptops, smartphones, tablets, and portable wearable devices.

[0031] In one embodiment, such as Figure 1 As shown, a blockchain-based regional intelligent operation and management method is provided, the method comprising:

[0032] Step S100: Based on the preset blockchain identification module, obtain the current operator's DID digital identity input by the current operator, and perform permission authentication on the current operator's DID digital identity. When the permission authentication is successful, obtain the current operator's current operation requirement data, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation.

[0033] Furthermore, if the authorization fails, no further action will be taken.

[0034] Step S200: Obtain the required equipment location information of each of the power grid devices required for the current operation, and collect the current status data of each of the power grid devices required for the current operation based on the required equipment location information using a preset information acquisition module;

[0035] Step S300: Based on the current status data, determine the availability of each of the power grid devices required for the current operation. When it is determined that all the power grid devices required for the current operation are in an available state, obtain the simulated operation verification expression of the current operator, and generate a simulated start command based on the simulated operation verification expression.

[0036] Step S400: According to the simulation start command, control the virtual power grid equipment corresponding to the power grid equipment required for the current operation to perform simulated operation according to the current operation steps, generate simulation operation results, generate operation demonstration tutorial based on the simulation operation results, and send the operation demonstration tutorial to the preset information receiving terminal of the current operator to guide the current operator to operate the power grid equipment required for the current operation.

[0037] In this embodiment, to accurately obtain the user's identity and perform authentication, an authorization step is set up. Specifically, based on a preset blockchain identification module, the current operator's DID digital identity is obtained, and authorization is performed on the current operator's DID digital identity. When authorization is successful, the current operator's current operation requirement data is obtained. Next, in order to accurately simulate according to actual needs, it is necessary to first determine whether the actual equipment can be used normally. Before this, it is necessary to obtain the specific location of each required device. Therefore, the location information of each required power grid device for the current operation is obtained first, and the current status data of each required power grid device for the current operation is collected based on the location information of the required devices using a preset information collection module. Next, in order to further accurately determine whether each device is usable, the usability of each required power grid device for the current operation is determined based on the current status data. Only when it is determined that all required power grid devices for the current operation are usable will the operation continue, that is, the simulated operation verification expression of the current operator is obtained, and the simulated operation verification expression is used to determine whether the device is usable. A simulated start command is generated. Finally, to improve safety and the operability of subsequent operations, a simulated operation is performed on the virtual power grid equipment corresponding to the power grid equipment required for the current operation, according to the simulated start command and the current operation steps. The simulated operation result is then generated, and an operation demonstration tutorial is created based on the result. This tutorial is sent to the operator's preset information receiving terminal to guide the operator in controlling the power grid equipment required for the current operation. This provides guidance to the operator and improves the safety of the operation process. Therefore, this invention first obtains the operator's identity and performs identity authentication. The obtained identity is a blockchain-based DID digital identity, ensuring the reliability and accuracy of identity authentication. Furthermore, the use of blockchain enables confidential operation in power grid control. The blockchain identification module also retains and records operation records, leveraging the immutability of blockchain technology to enhance confidentiality and data authenticity. This provides stable data support for subsequent record tracing of power grid operations.

[0038] In one embodiment, step S400: According to the simulation start command, the virtual power grid device corresponding to the power grid device required for the current operation is controlled to perform a simulated operation according to the current operation steps, and a simulated operation result is generated. An operation demonstration tutorial is generated based on the simulated operation result, and the operation demonstration tutorial is sent to the preset information receiving terminal of the current operator to guide the current operator in controlling the power grid device required for the current operation; specifically including:

[0039] Step S410: According to the simulated start command, obtain the regional sub-station associated with the current operation step;

[0040] Step S420: The current operation step is split into steps according to each of the regional substations. After the step splitting is completed, segmented splitting steps are generated, wherein each of the segmented splitting steps is arranged in sequence.

[0041] In this embodiment, the current operation steps are for different regional substations, specifically different regional substations. A regional substation is a collective term for several electrically connected substations in a power system. In a power system, substations of different voltage levels and locations can be considered as independent electrical points. These electrical points are electrically connected through power lines to transmit electrical energy and communication data, thereby forming a regional power grid among several electrical points. Several or more such electrically connected substations can be considered as a regional substation.

[0042] like Figure 2 As shown, there are n regional substations, namely Regional Substation 1, Regional Substation 2, Regional Substation 3, and so on up to Regional Substation n. The regional substations communicate with each other via a dispatch data network. Specifically, the status information of the primary and secondary equipment within each electrical substation is transmitted to the server of the regional intelligent operation and control system through the dispatch data network.

[0043] The current operation steps are not only for one substation, but can be for multiple regional substations. Therefore, different steps in the current operation steps are for different regional substations, and specifically for equipment within different regional substations. Therefore, in order to make accurate judgments and identifications, the regional substations associated with the current operation steps are first obtained according to the current operation steps, and then the current operation steps are broken down according to each regional substation. After the steps are broken down, segmented steps are generated, wherein each segmented step is arranged in sequence.

[0044] For example, when the current operation steps are three steps, namely the first step, the second step, and the third step, where the first step is for regional substation 1, and the second and third steps are for regional substation 2, then the generated segmentation steps are segmented according to the regional substations, specifically into two segmentation steps.

[0045] Step S430: Perform a simulation operation on the first segmentation step in each of the segmentation steps, and generate the first segmentation simulation result;

[0046] Step S440: When the first segmentation simulation result is deemed qualified, the simulation operation is performed sequentially on the other segmentation steps except for the first segmentation step, until the segmentation simulation results generated for each segmentation step are deemed qualified. Then, the segmentation simulation results are summarized to generate the simulation operation result.

[0047] Step S450: Generate an operation demonstration tutorial based on the simulation operation results, and send the operation demonstration tutorial to the current operator's preset information receiving terminal to guide the current operator in operating the power grid equipment required for the current operation.

[0048] In this embodiment, to ensure that the simulation of the next segmentation step is only performed after the first segmentation step has been correctly simulated, this ensures that simulation errors are detected and corrected in a timely manner, preventing errors in the current step from affecting the simulation results of the next step, and simultaneously improving accuracy and reliability. Specifically, the simulation operation is first performed on the first segmentation step of each segmentation step, generating a first segmentation simulation result. When the first segmentation simulation result is deemed qualified, the simulation operation is performed sequentially on the other segmentation steps except for the first segmentation step, until the segmentation simulation results generated for each segmentation step are all determined to be qualified. Then, all the segmentation simulation results are summarized to generate a simulation operation result. The sequential simulation means that the simulation is performed after the first segmentation simulation result is obtained. The second segmentation step is simulated. Only when the simulation result of the second segmentation step is qualified is the simulation of the third segmentation step performed. That is, the simulation operation is performed sequentially for all segmentation steps except the first segmentation step until the segment simulation result generated for each segmentation step is determined to be qualified. Then, the simulation results of each segment are summarized to generate the simulation operation result. This ensures that the simulation operation result is generated under the premise that the simulation result is correct, and that the operation demonstration tutorial generated based on the simulation operation result is correct and reliable. Therefore, after the operation demonstration tutorial is sent to the current operator's preset information receiving terminal, it can achieve the purpose of correctly guiding the current operator to operate the power grid equipment required for the current operation, thereby improving the safety and reliability of the operation.

[0049] Furthermore, when determining whether the first segmented simulation result is qualified, a standard simulation result is preset, so that the first segmented simulation result is compared with the standard simulation result, and if they match, it is qualified.

[0050] In one embodiment, step S100: Based on a preset blockchain identification module, the current operator's DID digital identity is obtained, and the current operator's DID digital identity is authenticated. Upon successful authentication, the current operator's current operation requirement data is obtained, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation; specifically including:

[0051] Step S110: Obtain the current operator's DID digital identity based on the preset blockchain identification module;

[0052] Step S120: Verify the current person's DID digital identity, determine whether the current person's DID digital identity matches the preset qualified identity, and generate an authorization authentication pass indication;

[0053] Step S130: Generate a pre-operation instruction based on the authorization authentication instruction;

[0054] Step S140: Obtain the current operation requirement data made by the current operator based on the pre-operation instruction, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation.

[0055] In this step, the current personnel's DID digital identity serves as proof of the current operator's actual identity. By setting the current operator's DID digital identity and performing authorization authentication on it, subsequent data processing, i.e., obtaining the current operator's current operational requirement data, is only performed after authorization authentication is successful. To ensure the smooth and efficient acquisition of the current operational requirement data, operation instructions are provided. Specifically, after verifying the current personnel's DID digital identity and determining whether it matches a preset qualified identity, and generating an authorization authentication success instruction, a pre-operation instruction is generated based on the authorization authentication success instruction. Then, the current operator's current operational requirement data based on the pre-operation instruction is obtained. This ensures the reliability of obtaining the current operation steps and the power grid equipment required for the current operation.

[0056] In one embodiment, step S200: obtaining the required equipment location information of each of the power grid devices required for the current operation, and collecting the current status data of each of the power grid devices required for the current operation based on the required equipment location information using a preset information acquisition module; specifically including:

[0057] Step S210: Send a positioning query command to the preset positioning module on each of the power grid devices required for the current operation according to the current operation requirements; wherein the preset positioning module is preset.

[0058] Step S220: Obtain the required device location information fed back by the preset positioning module according to each of the positioning query instructions, wherein the required device location information includes the current actual location of each of the power grid devices required for the current operation;

[0059] Step S230: Send an information collection instruction to the information collection module corresponding to the current actual location according to the current actual location, wherein the information collection module is preset, and the information collection module collects information on at least one power grid device required for the current operation;

[0060] Step S240: Based on the preset information acquisition module, the installation status and integrity status of each power grid device required for the current operation are collected according to the location information of the required device, wherein the installation status and integrity status are the current status data.

[0061] In this embodiment, to improve the accuracy and reliability of positioning, a positioning query command is sent to a preset positioning module on each of the power grid devices required for the current operation. In actual production, the preset positioning module and the power grid devices required for the current operation are installed in the same area, thus establishing a one-to-one correspondence between the preset positioning module and the power grid devices required for the current operation. This allows the positioning information of the required devices to be obtained based on each positioning query command, thereby obtaining the actual location of each of the power grid devices required for the current operation. Unlike conventional settings that send fixed positioning information, the preset positioning module provides real-time feedback on the location information of the power grid devices required for the current operation. That is, the location of the power grid devices required for the current operation may change, and when the location of the power grid devices required for the current operation changes, the preset positioning module provides real-time feedback on the location information of the power grid devices required for the current operation. The preset positioning module automatically locates a new position, or the personnel moving the power grid equipment required for the current operation update the position stored in the preset positioning module, thereby accurately obtaining the position of the power grid equipment required for the current operation. Then, based on the current actual position, an information collection command is sent to the information collection module corresponding to the current actual position. Based on the preset information collection module, the installation status and integrity status of each power grid equipment required for the current operation are collected according to the location information of the required equipment. The installation status and integrity status are the current status data. The information collection module is preset, and the information collection module collects at least one power grid equipment required for the current operation. Specifically, the information collection module includes at least an industrial camera, so that the user can take pictures to obtain image data. Further, after analyzing the image data, the integrity and installation position can be obtained. The installation status is determined by obtaining the installation position, including but not limited to whether the installation position has changed and whether it is installed correctly. The integrity status indicates whether it is damaged. Therefore, the availability of the power grid equipment required for the current operation is characterized by the installation status and integrity status.

[0062] In one embodiment, step S300: Based on the current status data, determine the availability of each power grid device required for the current operation; when it is determined that all the power grid devices required for the current operation are in an available state, obtain the simulated operation verification expression of the current operator, and generate a simulated start command based on the simulated operation verification expression; specifically including:

[0063] Step S310: Determine the physical structure integrity of the power grid equipment required for the current operation based on the installation status and integrity status in the current status data, wherein one power grid equipment required for the current operation corresponds to one physical structure integrity.

[0064] Step S320: Based on the integrity of each entity structure, screen out the unqualified power grid equipment required for the current operation, and send the current actual location of the unqualified power grid equipment required for the current operation to the equipment maintenance personnel to guide the equipment maintenance personnel to replace the equipment;

[0065] Step S330: When all the power grid devices required for the current operation are qualified according to the integrity of the entity structure, a trigger pre-instruction is generated and the trigger pre-instruction is sent to each of the power grid devices required for the current operation;

[0066] In this embodiment, to ensure that the status of each power grid device required for the current operation is qualified and usable, the physical structural integrity of the power grid device required for the current operation is first determined based on the installation status and integrity status in the current status data. Then, unqualified power grid devices are screened according to the physical structural integrity of each device, and the current actual location of the unqualified devices is sent to the equipment maintenance personnel to guide them in replacing the devices. This process of guiding the equipment maintenance personnel to replace the devices continues until all the power grid devices required for the current operation are qualified according to the physical structural integrity. Only then is the usability check of the external form of the power grid devices required for the current operation completed. Next, to complete the electrical check, a trigger pre-command is generated and sent to each power grid device required for the current operation. By debugging the power grid devices required for the current operation, the usability can be accurately determined.

[0067] Step S340: Obtain the real-time feedback results of the pre-operations performed by each of the power grid devices required for the current operation according to the trigger pre-instruction;

[0068] Step S350: Based on the real-time feedback results, filter the power grid equipment required for each current operation until all the power grid equipment required for each current operation is qualified. Then, determine that all the power grid equipment required for each current operation is in a usable state. Obtain the simulated operation verification expression of the current operator and generate a simulated start command based on the simulated operation verification expression.

[0069] Furthermore, by setting up real-time feedback results of the pre-operations performed by each of the required power grid devices according to the trigger pre-instruction, including feedback results during operation, the required power grid devices are screened based on these real-time feedback results until all required devices are deemed qualified, indicating that all required devices are in a usable state. To further ensure the operator's authorization, a simulated operation verification expression of the current operator is obtained. This simulated operation verification expression is specific information held by the current operator, specifically a VC (Verifiable Presentation). This simulated operation verification expression is a credential information expressing the current operator's identity, distinct from their DID (Digital Identity). The simulated operation verification expression is simpler, enabling further authorization verification. The simulated operation verification expression and the current operator's DID provide dual verification, generated using blockchain technology, significantly improving reliability and accuracy.

[0070] In one embodiment, such as Figure 3 As shown, the present invention also provides a blockchain-based regional intelligent operation and control system, the system comprising:

[0071] The authorization module is used to obtain the current operator's DID digital identity based on the preset blockchain identification module, and to perform authorization authentication on the current operator's DID digital identity. When the authorization authentication is successful, the module obtains the current operator's current operation requirement data, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation.

[0072] The status determination module is used to obtain the required equipment location information of each of the current operation's required power grid equipment, and to collect the current status data of each of the current operation's required power grid equipment based on the required equipment location information using a preset information acquisition module.

[0073] The simulation operation module is used to determine the availability of each power grid device required for the current operation based on the current status data. When it is determined that all the power grid devices required for the current operation are in an available state, the module obtains the simulation operation verification expression of the current operator and generates a simulation start command based on the simulation operation verification expression.

[0074] The operation instruction module is used to control the virtual power grid equipment corresponding to the power grid equipment required for the current operation to perform simulated operation according to the current operation steps based on the simulation start command, generate simulation operation results, generate operation demonstration tutorial based on the simulation operation results, and send the operation demonstration tutorial to the preset information receiving terminal of the current operator to guide the current operator to operate the power grid equipment required for the current operation.

[0075] In one embodiment, the operation indication module is further configured to:

[0076] According to the simulation start command, the associated regional substation of the current operation step is obtained according to the current operation step; the current operation step is broken down into steps according to each regional substation, and segmented steps are generated after the steps are broken down, wherein the segmented steps are arranged in sequence; the first segmented step in each segmented step is simulated and the first segmented simulation result is generated; when the first segmented simulation result is qualified, the other segmented steps except the first segmented step are simulated in sequence until the segmented simulation results generated for each segmented step are all qualified, and the segmented simulation results are summarized to generate a simulation operation result; an operation demonstration tutorial is generated according to the simulation operation result, and the operation demonstration tutorial is sent to the preset information receiving terminal of the current operator to guide the current operator to operate the power grid equipment required for the current operation.

[0077] In one embodiment, the simulation operation module is further configured to:

[0078] The physical structural integrity of the power grid equipment required for the current operation is determined based on the installation status and integrity status in the current status data, wherein one power grid equipment required for the current operation corresponds to one physical structural integrity. Unqualified power grid equipment is filtered based on each physical structural integrity, and its current actual location is sent to the equipment maintenance personnel to guide them in replacing the equipment. When all the power grid equipment required for the current operation is qualified based on the physical structural integrity, a trigger pre-instruction is generated and sent to each of the power grid equipment required for the current operation. Real-time feedback results of each power grid equipment performing pre-operations according to the trigger pre-instruction are obtained. Based on the real-time feedback results, each power grid equipment is filtered until all are qualified, at which point each power grid equipment is determined to be in a usable state. The simulated operation verification expression of the current operator is obtained, and a simulated start-up instruction is generated based on the simulated operation verification expression.

[0079] In one embodiment, the state determination module is further configured to: send a positioning query instruction to a preset positioning module on each of the power grid devices required for the current operation, wherein the preset positioning module is pre-set; obtain the required device positioning information fed back by the preset positioning module according to each positioning query instruction, wherein the required device positioning information includes the current actual positioning of each of the power grid devices required for the current operation; send an information collection instruction to an information collection module corresponding to the current actual positioning, wherein the information collection module is pre-set, and the information collection module collects information on at least one of the power grid devices required for the current operation; and collect the installation status and integrity status of each of the power grid devices required for the current operation based on the required device positioning information from the preset information collection module, wherein the installation status and integrity status are the current state data.

[0080] In one embodiment, the state determination module is further configured to: obtain the current personnel's DID digital identity input by the current operator based on a preset blockchain identification module; verify the current personnel's DID digital identity and determine whether the current personnel's DID digital identity matches a preset qualified identity, and generate an authorization authentication pass indication; generate a pre-operation indication based on the authorization authentication pass indication; and obtain the current operation requirement data made by the current operator based on the pre-operation indication, wherein the current operation requirement data includes the current operation steps and the power grid equipment required for the current operation.

[0081] In one embodiment, such as Figure 4 As shown, the network structure of the regional intelligent operation and control system is divided into a data application layer, a data transmission layer, and a terminal station layer. The network structure is introduced using two substations of the regional intelligent operation and control system as an example.

[0082] Specifically, the data application layer deploys a scheduling system front-end server, a regional intelligent operation and control system host, a forward isolation device (forward isolation shown in the figure), a VPN server, and an SMS sending terminal.

[0083] The data transmission layer mainly consists of scheduling data network equipment, which is used for data transmission from terminal stations.

[0084] The terminal station layer includes intelligent five-proof key, remote control unit (RTU), station control layer switch, monitoring back-end computer, protection and control device, and primary and secondary equipment in the field.

[0085] Furthermore, based on the aforementioned blockchain-based regional intelligent operation and control system, a method for realizing coordinated operation of the regional power grid can also be implemented, specifically as follows:

[0086] The status information of primary and secondary equipment at the terminal station level is transmitted to the remote control unit (RTU) and monitoring backend computer via the protection and control device and the station control layer switch. The RTU transmits the information to the front-end server of the D5000 / OPEN3000 dispatch system through the security zone I of the dispatch data network. The host of the regional intelligent operation and control system shares the data of this server and obtains the status information of primary and secondary equipment in the station in real time. When equipment operation is performed, the regional intelligent five-prevention host analyzes and makes logical judgments on the status of equipment in each substation with regional connection, and then issues operation instructions to the terminal station intelligent five-prevention key through the VPN network.

[0087] On-site operators perform equipment operation based on the equipment operation instructions received by the intelligent five-prevention key at this station. The equipment status after operation is then transmitted again to the front-end server and the regional intelligent five-prevention host via the station's protection and control devices and remote control units (RTUs). The system automatically identifies and judges the equipment status, issuing new operation instructions only after the previous step has been correctly executed and the regional five-prevention logic conditions are met. If substation 1 completes the operation correctly, but the system determines that the regional five-prevention logic is not met, a waiting operation instruction is issued to substation 1 until the regional five-prevention conditions are met before issuing the next operation instruction. If the system determines that the operation execution is incorrect, it will promptly issue an operation error reminder to the intelligent key, reminding the operator to correct the error in time, effectively preventing misoperation during the regional substation linkage process, thereby achieving effective control over the operation of primary and secondary equipment.

[0088] The control logic of regional intelligent operation and control systems can be divided into forward control logic and interlocking control logic according to their working principles. Interlocking control logic is commonly used in mechanical anti-misoperation interlocking systems, electrical anti-misoperation interlocking systems, and stand-alone microcomputer-based anti-misoperation interlocking systems. Its logic is simple, the data is singular, and data sharing is not possible. However, if interlocking rules are used in integrated five-prevention systems based on station monitoring systems and topological five-prevention systems based on SCADA / EMS, there will be problems such as a large amount of computational data and many logical judgment rules. Therefore, forward control logic is often used.

[0089] Compared to existing regional control systems where equipment operation is entirely controlled by on-site operators—typically one operation ticket per task, with operators issuing all steps to the five-prevention key at once, and on-site operators executing the steps according to the key sequence, verifying the results after each step—this invention provides a regional intelligent operation control system that automatically determines equipment status by sharing RTU data within the substation and issuing operation instructions to the corresponding substation's intelligent five-prevention key step by step, ensuring that every step of equipment operation is controllable and under control. The control logic of the regional intelligent operation control system will now be described using the example of a power outage maintenance of the connection line between substations A and B in a regional power grid.

[0090] Specifically, such as Figure 5As shown, station A has line bay number 211, and station B has line bay number 222. Both stations A and B are equipped with intelligent five-prevention keys. The upstream power supply of both stations, a 330kV substation, is equipped with a regional intelligent five-prevention host. Equipment status data between the three stations is transmitted through the dispatch data network. After the operation begins, stations A and B can operate simultaneously. The operation procedure is as follows: Figure 6 As shown.

[0091] As shown in the operation flowchart, during the operation of stations A and B, steps 1 to 4 can be carried out simultaneously. The system automatically identifies the equipment status of the two stations. When the line grounding switch is operated in step 4, the two stations carry out coordinated operations. Compared with traditional operations, this greatly reduces the dispatcher's coordination and command process in traditional operations.

[0092] Furthermore, the status of the grounding switch on the opposite side serves as the basis for determining whether the grounding switch on this station is allowed to close. Taking the 211-0 grounding switch at station A as an example, its logic for allowing closing is as follows: Figure 7 As shown.

[0093] To prevent the grounding switch from being closed while energized, the conditions under which the grounding switch 211-0 at station A can be closed are: station A's 211-3 switch has been opened and the A and B lines are de-energized, or station B's 222-0 switch has been closed and the A and B lines are de-energized. Through information sharing between regional power grids, it is ensured that the lines are indeed de-energized before the grounding switch is closed. In addition, the system must also consider a fault-tolerance mechanism. If the remote signaling or telemetry criterion for line de-energization fails, manual handling can be initiated to prevent the failure of a single criterion from affecting the equipment's power outage and restoration operations.

[0094] In one embodiment, to ensure that the deployment of the regional intelligent operation and control system meets network information security requirements, firstly, a forward isolation device is deployed between Security Zone I and Security Zone IV, allowing data to be transmitted only from Security Zone I to Security Zone IV, thereby ensuring the network information security of cross-zone business data. Secondly, during the issuance of operation instructions, the instructions are sent to the intelligent five-proof key within the substation via a VPN server. If this intelligent five-proof key uses an encrypted SIM card, the entire process of data issuance, transmission, and reception can be encrypted. Furthermore, the intelligent five-proof key can be configured to only allow one-way reception, preventing the transmission of operation instructions to the VPN server via the built-in SIM card, thus ensuring the network information security of the data.

[0095] In one embodiment, in order to push the abnormal alarm information generated by the control system based on the real-time judgment of different equipment operations to the operation and maintenance personnel, guide the operation and maintenance personnel in subsequent equipment operations, improve the correctness and safety of equipment operations, avoid missed operations, misoperations, or incorrect operation sequence, and prevent the occurrence of accidents.

[0096] Specifically, such as Figure 8As shown, the monitoring information acquisition unit of the control system operates in Zone I of the substation. It sends the monitoring information to the control host through the isolation device. The control host also receives the equipment sensing status sent by the equipment sensing concentrator. The control host pushes the abnormal alarm information of the control system to the mobile phones of relevant operation and maintenance personnel via SMS.

[0097] Specifically, firstly, the data from the monitoring information collection unit in Zone I is sent to the control host in Zone IV through the isolation device A between Zone I and Zone IV; then, the secondary equipment sensing concentrator sends the sensing status of the secondary equipment to the control host in Zone IV wirelessly; next, when the control host in Zone IV detects abnormal operation, it sends the abnormal alarm information to the mobile phone of the relevant operator through the SMS sending terminal.

[0098] In one embodiment, such as Figure 9 As shown, a computer device includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the steps described in the blockchain-based regional intelligent operation and control method.
