Description

Technical Field

[0001] The present application relates to the field of data security technology, and in particular to a dual-channel data asynchronous communication method, system and storage medium across power safety zones. Background Art

[0002] With the implementation of the construction of the new power system, the number of power generation entities connected to the grid has increased rapidly. In addition to traditional thermal power and hydropower, photovoltaics, energy storage, and virtual power plants have grown rapidly. The diversification and scale of power generation entities have brought new coordination problems to grid control. The demand for dispatch coordination between the grid and power generation entities is increasing, and data security communication issues need to be urgently resolved.

[0003] In order to ensure the security of the power monitoring system and prevent attacks and infringements on the power monitoring system by hackers and malicious codes, the overall principle of security protection of the power monitoring system is "security zoning, network dedicating, horizontal isolation, and vertical authentication".

[0004] At present, power safety zones include production control zones and management information zones. The data exchange between the production control zones and the management information zones is protected by safety isolation devices. Power stations distributed in the production control zones and the control center transmit data safely through the power dispatching data network. For power plants with large installed capacity, they need to open access channels to the control area (safety zone I) of the production control zone with the control center to transmit real-time data and control instructions. For power plants in non-coordinated areas, the number of data channels opened in the non-control area (safety zone II) for transmitting non-real-time data is relatively small, and most power plants do not have the technical conditions to transmit non-real-time data to the control center through the non-control area.

[0005] In order to ensure the safety, stability and economic operation of the power grid, the control centers at all levels regularly conduct statistics, summary and decision-making on the power generation plans within their jurisdiction in accordance with the principle of hierarchical and regional management. The data interaction between power generation enterprises, power plants and control centers is relatively frequent. Due to the technical limitations of security partitions and physical isolation between power grid enterprises and power generation enterprises, the power generation enterprises under the jurisdiction of county-level power grids and the power grid control center cannot transmit data through a penetrating TCP port connection, but can only transmit data indirectly. The transmission is usually carried out in a traditional Excel file, which is transmitted one-way to the mobile phones and emails of the control personnel through WeChat, email attachments, etc. Its transmission efficiency and data structuring degree cannot meet the needs of direct use by computer management systems. Moreover, the process of transferring data files to the power intranet cannot be separated from the manual participation of the control center personnel (for example, the staff needs to manually copy files from communication tools such as emails and WeChat to a secure U disk, and then transfer the files to the power intranet through the secure U disk). If these data are to be used further, a large amount of manpower is required for secondary processing of the data. According to the management requirements of the State Grid, the existing computer data synchronization transmission communication technology has security risks and secondary security protection requirements. It does not allow direct external network contact and can only transmit data files in an isolated one-way manner. It can neither meet the data interaction needs of power generation entities and power grid control centers, nor solve the problems of low efficiency, poor security, and low degree of automation in the data transmission process, which limits the effective development of related businesses.

[0045] With the increase in installed capacity and output of new energy, the control centers at all levels of power grids are paying more and more attention to suppressing the risks of power grid operation caused by the volatility of new energy. Using power generation resources with flexible adjustment capabilities to suppress volatility from a planning level is an important measure to ensure the daily safe operation of the power grid. Common flexible resources include hydropower, energy storage, and diesel generators. The various resources need to be coordinated in advance so that they can be adjusted when the power grid fluctuates. The power generation plan is a conventional means of participating in the coordination of the power grid. For power grids in non-coordinated areas, when performing day-ahead balancing, it is necessary to grasp the output plans of various power generation entities in the region, and verify the power generation plan according to the specific conditions of the power grid power balance and power grid maintenance.

[0046] For each power generation entity, submitting plans to the grid control center via the Internet is a low-cost communication solution. However, due to requirements such as secondary safety protection of the grid, the computer networks of non-coordinated power plants and grid companies cannot be directly connected, and information exchange cannot be completed through computer synchronous communication.

[0047] The idea of ​​this application is to decompose the entire data communication process into two weakly related transactions, the uplink and the downlink. The uplink transaction is triggered by the power station side and transmitted to the control center processing system by a one-way relay push of file data. After processing the business, the control center starts the downlink transaction trigger process and pushes the transaction data to the transaction interrupt by a one-way relay of files. After that, the transaction data is decomposed into SMS data packets through protocol conversion, and the data packets are sent out unidirectionally through mobile SMS. The closed-loop communication between the power station and the control center is completed through a segmented asynchronous non-handshake method.

[0048] The technical solution provided by this application is not only suitable for power generation plan reporting, but also suitable for other business data reporting. The conversion of other transactions can be completed by simply modifying the protocol that meets business needs. The following is a detailed description of this application in conjunction with the power generation plan reporting embodiment.

[0049] like Figures 1 to 5 As shown, the present application provides a dual-channel data asynchronous interaction method across power safety zones, comprising the following steps:

[0050] S100, obtain the business data that the plant needs to interact with. The traditional way of power generation planning is to submit it based on Excel files. By adopting the technology of this application, you can log in to the plan submission software through the computer network, and complete the plan submission, business data collection and feedback in the software.

[0051] S200, mark and standardize the uplink transaction data: In order to enable the control center to directly identify the relevant business data, it is necessary to identify the transaction represented by the data itself each time it is transmitted. By identifying the transaction, the data transmitted by any power station at different times is unique, identifiable, and holographic. The control center only needs to parse out all the information required to process the transaction from the data to determine the transaction. Taking the power generation plan as an example, when a power station wants to report and send the plan, since the power generation plan processing involves multiple links, each link needs to have a transaction tag for the corresponding link, so that the activities of the next link can judge the transaction status based on the transaction tag.

[0052] Taking the report plan submitted by power station A as an example, a complete uplink transaction identifier should include the following information:

[0053] 1) The name or coding information of the power station, such as the dispatching code of the power station

[0054] 2) Category information of power station.

[0055] 3) Planned time period information;

[0056] 4) Overall status of the plan

[0057] 5) Mobile phone number

[0058] 6) Detailed data for each plan item

[0059] After the planned transaction is marked, the planned business data needs to be packaged in a standardized manner to meet the file transfer requirements. When transferring files, they must be packaged in accordance with the CIM / E file method. Otherwise, some isolation devices and firewalls are likely to refuse to pass the file during the compliance check. For files that do not meet the requirements, they cannot be transferred, resulting in interruption of the transfer process. Figure 3 Example of an upstream transaction file for transmitting a power generation plan.

[0060] S300 uses the reverse secure transmission channel to relay the encapsulated uplink transaction data to the power grid control center

[0061] The reverse secure transmission channel includes a network spanning the power Internet area, the power management information area, and the production management area, a reverse isolation device, a firewall, and application software to ensure secure data reception. The reverse isolation device refers to a hardware device and supporting transmission software for unidirectional transmission from a low-security partition to a high-security partition. The uplink transaction data refers to textual, non-command, non-binary data, which usually refers to an E-file data transmission method that meets the requirements of the State Grid.

[0062] The number of relay transmissions of the uplink transaction data file is determined according to the deployment location of the device where the uplink transaction data is obtained during the control. Sometimes it is necessary to cross multiple isolation devices to reach the control center, and each node needs to relay the transmission. During the transmission, the transmission software is also required to cooperate.

[0063] S400, controlling the power grid control center to receive the uplink transaction data, perform business verification and processing on the data, generate downlink transaction data, and perform downlink transaction marking and standardized packaging.

[0064] After receiving the uplink transaction data file, the control center needs to parse and process the uplink transaction based on the business type and characteristics. Taking the power generation plan as an example, when receiving the plan reported by the power station, it is necessary to obtain the status and detailed information of the transaction from the transaction file, and verify the security and economy of the transaction data in combination with the system operation specifications and technical standards, and combine the verification results with the uplink transaction to generate downlink transaction data.

[0065] For example, during certain periods during holidays, the load rate on some lines is relatively low, while the grid-connected photovoltaic power stations generate large amounts of power, which can easily cause reverse overload and affect the safety of the power grid. At this time, it is necessary to limit the output of the connected hydropower stations and energy storage power stations, and the power generation plan of the power station needs to be adjusted. The power generation plan adjustment value for a certain period of time after verification by the control center constitutes the main content of the downstream affairs. The output plan target value for a specific period of time to be adjusted must be sent to the power station so that the power station can execute the adjusted power generation plan within the specified period of time.

[0066] S500, the encapsulated downlink transaction data is transmitted by relaying the forward secure transmission channel.

[0067] After the control center completes data verification, downlink transaction marking and standardized packaging, it must push the data to a platform capable of sending text messages through a forward secure transmission channel. Generally speaking, the platform that sends text messages is often located in the information management area and often needs to cross the forward secure isolation for relay transmission.

[0068] S600, split the downlink transaction data into data packets according to the protocol, and use the short message sending system to quickly distribute the split data packets.

[0069] When downlink transaction data is transmitted to the power station, it is necessary to decompose the transaction data into data suitable for transmission on the SMS platform. In order to ensure reliable, stable, continuous data transmission and data integrity, the data packet decomposition needs to take into account the characteristics of SMS. Its length has an upper limit and a certain flexibility. It should be parsed according to the application protocol in combination with the business. The application protocol can adopt existing protocols or be customized. The following is only a private protocol format for transmitting power generation plans, not the only protocol. Any protocol format, content reorganization and data item order change are not allowed. It does not affect the execution of this application; for example, the content of the power generation plan data packet can refer to the following content to customize the private application protocol: region, message type, content type, plan date, power station type, unit name, time, release value, end mark. Taking H12[202405281A power station_#117.250] as an example, it represents the active power plan instruction of the #1 unit of the A hydropower station in the H area on May 28, 2024 issued by the control center. The output of the power station at 1 o'clock should be 7.25MW, and this data packet is the last instruction released in batches.

[0070] After the data packets are parsed, the SMS platform can be used to send all the parsed data packets one by one or in batches.

[0071] S700 performs conversion and cloud transmission. It receives and analyzes SMS data packets, performs data protocol conversion and storage, and updates the plant-side display to complete the closed-loop transaction processing.

[0072] To receive SMS data packets, you need to use a SIM card and an operating system that supports reading SMS, such as the Android operating system, Apple's IOS, or Huawei's Kirin operating system, to read the SMS data, parse the SMS content according to the application protocol, and aggregate it into corresponding transaction data.

[0073] Store transaction data in the cloud and update plant business status to complete closed-loop processing of the business.

[0074] like Figure 2 As shown, the present application also provides a dual-channel data asynchronous interaction system across power safety zones, which mainly includes a client module 10, a cloud server module 20, an uplink communication module 30, a verification module 40, a downlink communication module 50, a mobile communication module 60, and a short message communication module 70. Among them, the mobile communication module 60 can be composed of a telecommunications or mobile enterprise-level short message platform and a short message sending system.

The main function of the client module 10 is to transmit the latest plan data to the cloud, and to obtain the latest plan verification status information from the control center from the server in a timely manner.

[0077] When a new weekly plan is needed, the power station staff only needs to log in to the client module 10 and use the application software (such as Figure 4 As shown in the figure, a new plan can be reported. After the cloud server module 20 obtains the newly reported plan data, it automatically performs uplink transaction marking and standardized file packaging on the data to generate a CIM / E file that meets the power grid communication requirements. The uplink communication module 30 located in the Internet area of ​​the power grid company is connected to the cloud server module 20 to automatically obtain the data in the cloud server module. The uplink communication module 30 is distributed in the Internet area, management information area, and production management area within the power grid company, and is respectively composed of one or more firewalls 31, front communication servers 32, reverse isolation devices 33, communication servers and databases 34. Among them, the role of the firewall 31 is to intercept untrusted data access between different network segments, and the main role of the front communication server 32 is to obtain plan data from the cloud server module 20 and transmit it to the communication server and database 34 through the reverse isolation device 33.

[0078] The data verification module 40 is connected to the database 34 through the firewall 35, obtains the structured uplink transaction data, and processes the uplink transaction (such as Figure 5 The calculation verification software shown in the figure) is sent to the downlink communication module 50 after processing, and the downlink communication module performs forward security transmission. The forward security transmission includes transmitting data files from the high security area to the low security area. It is composed of a forward isolation device, a firewall, etc. The downlink communication module parses the transaction data according to the application protocol, generates a mobile SMS data packet, and calls the enterprise-level SMS platform to send the data packet through the mobile communication module 60.

[0079] The SMS communication module 70 is responsible for receiving and processing SMS data, parsing and converting the received SMS data packets using the application protocol, and generating object-oriented transaction data. The SMS communication module is composed of a SIM card 71 capable of receiving SMS, a mobile phone or tablet computer 72 capable of reading SMS, or an industrial computer 73 capable of reading SMS, and an SMS processing program deployed thereon. The SMS communication module needs to be connected to the Internet and can be connected to the cloud server module 20. Specifically, it can be connected to the message communication bus 23 located in the cloud, and the parsed transaction data can be pushed to the communication bus to avoid data congestion caused by the low processing capacity of the SMS communication module.

[0080] The application server 21 located in the cloud can obtain transaction data from the message bus, store the processed transaction data in the cloud database server 22, and push the relevant transaction data to the client module 10, thereby completing the closed loop of transaction processing.

[0081] The plant and station end includes but is not limited to new energy sites, but also includes thermal power plants, hydropower plants, energy storage power stations, virtual power plants and other market entities that need to interact with the power grid control center for data and have the ability to adjust power generation capabilities.

[0088] The decomposition of downlink transactions refers to decomposing the transmission data according to the characteristics of the data and the amount of data carried by each SMS message, and generating data packets that meet the needs of SMS transmission.
