Description

Technical Field

[0001] This application relates to the field of satellite communication technology, and in particular to a satellite-based power grid terminal communication method, device, electronic device and medium. Background Technology

[0002] With the continuous development of low-Earth orbit (LEO) satellite technology, LEO satellite communication is now used in many fields, such as power grid transmission. Through communication terminals installed at the power grid terminals, communication connections are established between each power grid terminal in the power grid transmission system and LEO satellites. The working status of the power grid terminal itself and related information such as the surrounding environment are transmitted in real time to the main control terminal in the monitoring room via LEO satellites, thereby realizing remote monitoring. Among them, the power grid terminals can be power grid towers, relay transmission stations, etc.

[0003] However, the inventors of this application have discovered that a single low-orbit satellite needs to establish communication connections with multiple towers and forward information such as the working status and surrounding environment of multiple towers to the main control terminal in real time. During this process, if multiple towers malfunction, it is necessary to forward the information such as the working status and surrounding environment of multiple towers, as well as the power grid fault information of the malfunctioning tower. This will result in an excessive amount of information to be forwarded, causing the power grid fault information to be unable to be transmitted to the main control terminal in a timely manner, thereby reducing the efficiency of fault detection and subsequent maintenance.

[0041] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0043] This application provides a satellite-based power grid terminal communication method, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, a distributed device, or a cloud server that provides cloud computing services.

[0044] Reference Figure 1 A satellite-based power grid terminal communication method includes steps S101, S102, and S103, wherein...

[0045] S101, acquire at least two power grid fault information; wherein, the power grid fault information includes power grid terminal information.

[0046] In some embodiments, the target low-Earth orbit satellite provides communication services to multiple power grid terminals in the power grid transmission system within its communication coverage area. These power grid terminals include transmission towers, relay stations, etc., and both the transmission towers and relay stations are equipped with power grid fault monitoring equipment and communication terminals. The power grid fault monitoring equipment is used to monitor the equipment operating status and power transmission status of the transmission towers and relay stations. In the event of a fault in a power grid terminal, the power grid fault monitoring equipment generates power grid fault information and transmits the power grid fault information to the target low-Earth orbit satellite via the communication terminal.

[0047] Power grid fault information can include transmission voltage fault information, equipment operation fault information, and power grid terminal fault information. When at least two power grid terminals fail within the communication coverage area of ​​the target low-Earth orbit satellite, electronic equipment obtains at least two power grid fault information entries from the power grid fault monitoring equipment installed at each power grid terminal.

[0048] S102, determine the terminal node level and terminal node association information corresponding to at least two power grid terminal information respectively.

[0049] In some embodiments, the power grid terminal information includes the power grid location information and operating parameters of the power grid terminal. The electronic device preprocesses the acquired at least two power grid fault information entries to determine the power grid terminal information contained in each of the at least two fault information entries. Since there are certain relationships between power grid terminals in the power transmission system, such as parallel relationships, master-slave relationships, and relationships before and after power transmission, the electronic device, after acquiring at least two power grid fault information entries, can consider the terminal node level and terminal node relationship information of the corresponding power grid terminals when deciding how to forward the information. Higher terminal node levels correspond to higher maintenance timeliness requirements and a greater urgency in forwarding the fault information. Therefore, the electronic device can determine the corresponding terminal node level and terminal node association information based on the relevant information contained in the power grid terminal information, serving as the basis for subsequently determining the forwarding order of the at least two power grid fault information entries.

[0050] S103, based on the terminal node level and terminal node association information, determine the data forwarding priority of at least two power grid fault information.

[0051] In some embodiments, terminal node association information reflects the relationship between a power grid terminal and other power grid terminals; terminal node level reflects the importance of a power grid terminal in the power grid transmission system; the higher the terminal node level, the shorter the time required to determine the cause of the fault and the time required for fault repair when the corresponding power grid terminal fails; therefore, when the electronic device determines the terminal node level and terminal node association information of the power grid fault information, it uses the terminal node level and terminal node association information to determine the data forwarding priority, and then adaptively forwards at least two power grid fault information based on the data forwarding priority, thereby reducing the situation where more important power grid fault information cannot be forwarded in time due to the large amount of data to be forwarded.

[0052] S104, based on the data forwarding priority, generates a first data forwarding instruction, and based on the data forwarding priority and the first data forwarding instruction, controls the target low-orbit satellite to forward at least two power grid fault information to the main control terminal.

[0053] In some embodiments, the electronic device generates a first data forwarding instruction based on data forwarding priority and sends the first data forwarding instruction and forwarding priority to the target low-Earth orbit satellite. The target low-Earth orbit satellite responds to the first data forwarding instruction and, based on the forwarding priority, forwards at least two power grid fault messages sequentially to the main control terminal installed in the monitoring room, so as to convey the purpose of power grid equipment failure to technicians. Thus, in the case of multiple power grid terminals experiencing failures and generating multiple power grid fault messages, the data forwarding priority of each power grid fault message is determined based on the terminal node level and terminal node association information of the faulty power grid terminals. Based on the data forwarding priority, multiple power grid fault messages are forwarded reasonably, thereby reducing the occurrence of situations where important power grid fault messages cannot be forwarded in a timely manner due to the large amount of data to be forwarded, and improving the efficiency of power grid terminal fault monitoring and maintenance in the power grid transmission system.

[0054] In step S102, determining the terminal node level and terminal node association information corresponding to at least two power grid terminal information respectively includes: determining power grid node information based on power grid location information; determining terminal node association information based on power grid node information and power grid terminal operating parameters; and determining the terminal node level based on power grid node association information and power grid terminal operating parameters.

[0055] In some implementations, the operating parameters of a power grid terminal include connection parameters between the terminal and other power grid terminals, equipment operating parameters, etc. These parameters reflect the importance of the corresponding terminal within the power grid transmission system. Electronic devices input power grid location information into the simulated power grid transmission system network to identify the corresponding power grid terminal and retrieve its power grid node information. Subsequently, based on the power grid node information and the terminal's operating parameters, the electronic devices determine the terminal node association information corresponding to that terminal and, based on this association information and the terminal's operating parameters, determine the terminal node level.

[0056] In step S103, the data forwarding priority of at least two power grid fault information is determined based on the terminal node level and terminal node association information, including: determining whether there is an association relationship between the terminal node association information corresponding to the at least two power grid fault information respectively; if there is an association relationship between the terminal node association information corresponding to the at least two power grid fault information respectively, determining the high-low relationship between the terminal node levels corresponding to the at least two power grid fault information respectively; and determining the data forwarding priority of the at least two power grid fault information based on the high-low relationship.

[0057] In some embodiments, the grid terminals in the power transmission system are affected by the power transmission characteristics, and considering the different importance levels among the grid terminals, generally, the importance level of the grid terminal located upstream of the transmission line is higher than that of the grid terminal located downstream of the transmission line.

[0058] When at least two grid terminals are interconnected and both experience grid faults, the cause of the fault may simply be a failure in the primary grid terminal (of higher importance), leading to faults in other grid terminals besides the primary terminal. In this situation, to quickly determine the cause of the fault and facilitate subsequent repairs, grid fault information generated by the faulty equipment in the primary grid terminal (of higher importance) should be prioritized for forwarding.

[0059] Therefore, electronic devices can determine the data forwarding priority between at least two power grid fault information based on terminal node association information, and determine the hierarchical relationship between the power grid terminals corresponding to at least two power grid fault information based on the terminal node level; that is, electronic devices first determine whether there is an association relationship between the electronic devices and the terminal node association information corresponding to at least two power grid fault information.

[0060] If a correlation is found between the terminal node association information corresponding to at least two power grid fault information, it is preliminarily indicated that there may be a master-slave association or a circuit transmission relationship between the power grid terminals corresponding to at least two power grid fault information. The occurrence of at least two power grid terminal failures may be due to the failure of the high-level master power grid terminal, which led to the failure of the low-level slave power grid terminal.

[0061] Subsequently, the electronic equipment determines the high-low relationship between the terminal node levels corresponding to at least two power grid fault information, and determines the data forwarding priority of at least two power grid fault information based on the high-low relationship. Specifically, the data forwarding priority of power grid fault information corresponding to the high-level terminal node is defined as high priority, and the data forwarding priority of power grid fault information corresponding to the low-level terminal node is defined as low priority.

[0062] In some embodiments, after determining whether there is an association relationship between the terminal node association information corresponding to at least two power grid fault information respectively, the data forwarding priority of at least two power grid fault information is determined based on the terminal node level and the terminal node association information. The method further includes: if there is no association relationship between the terminal node association information corresponding to at least two power grid fault information respectively, determining that the data forwarding priority of at least two power grid fault information is the same priority; and the method further includes: generating a second data forwarding instruction based on the data forwarding priority, and controlling the target low-orbit satellite to forward at least two power grid fault information to the master control terminal simultaneously or sequentially based on the second data forwarding instruction.

[0063] In some embodiments, if the electronic device determines that there is no association between the terminal node association information corresponding to at least two power grid fault information, it indicates that there is no master-slave relationship or transmission sequence relationship between the power grid terminals corresponding to the at least two power grid fault information, which means that the faults of at least two power grid terminals are caused by different fault causes and are not related. At this time, the electronic device can determine that the data forwarding priority of at least two power grid fault information is defined as the same priority. Subsequently, the electronic device generates a second data forwarding instruction based on the data forwarding priority and sends the second data forwarding instruction to the target low-orbit satellite. The target low-orbit satellite responds to the second data forwarding instruction and forwards the at least two power grid fault information to the master control terminal simultaneously or sequentially.

[0064] In step S102, after determining the terminal node level and terminal node association information corresponding to at least two power grid terminal information respectively, the method further includes: determining associated fault information based on the terminal node level, terminal node association information and power grid fault information; generating a third data forwarding instruction based on the associated fault information; and controlling the target low-orbit satellite to forward the associated fault information to the master control terminal based on the third data forwarding instruction.

[0065] In some embodiments, the power grid transmission system consists of numerous power grid terminals, which have master-slave or transmission front-to-back relationships. Therefore, if a power grid terminal fails, it may cause other power grid terminals that are related to that power grid terminal or the power grid terminal itself to experience other failures caused by the failure, i.e., associated failures. Therefore, in order to quickly forward the power grid fault information generated by the power grid fault monitoring equipment, it is advisable to forward other fault information as well.

[0066] The terminal node level reflects the importance of the power grid terminal, and the terminal node association information reflects the correlation between the faulty power grid terminal and other power grid terminals. The electronic equipment analyzes the power grid fault information to determine the location and / or type of the fault in the power grid terminal, and determines the associated fault information based on the terminal node level and terminal node association information. Subsequently, the electronic equipment generates a third data forwarding instruction based on the associated fault information and sends the third data forwarding instruction and the associated fault information to the target low-orbit satellite. The target low-orbit satellite responds to the third data forwarding instruction and sends the associated fault information to the main control terminal installed in the monitoring room.

[0067] In step S104, based on the data forwarding priority and the first data forwarding instruction, the target low-Earth orbit satellite is controlled to forward at least two power grid fault information to the master control terminal. This includes: generating data forwarding delay time periods corresponding to the at least two power grid fault information based on the data forwarding priority and the first data forwarding instruction; when the high-priority power grid fault information is sent to the target low-Earth orbit satellite, the data forwarding delay time period of the high-priority power grid fault information starts timing, and when the data forwarding delay time period ends, the low-priority power grid fault information is sent to the target low-Earth orbit satellite; and the target low-Earth orbit satellite forwards the at least two power grid fault information to the master control terminal.

[0068] In some embodiments, when the amount of data that the target low-orbit satellite needs to forward is too large, in order to forward at least two power grid fault information smoothly, it is possible to set a corresponding data forwarding delay time period for at least two power grid fault information based on data forwarding priority and data forwarding instructions. For example, during the forwarding of the first power grid fault information, the second power grid fault information is forwarded with a lag, that is, after the first power grid fault information is forwarded, the second power grid fault information is forwarded.

[0069] The electronic device generates a data forwarding delay time period corresponding to at least two power grid fault information based on data forwarding priority and data forwarding instructions. When the power grid fault information corresponding to the higher priority data forwarding priority is sent to the target low-Earth orbit satellite, the data forwarding delay time period of the power grid fault information starts to count. The completion of the data forwarding delay time period indicates that the target low-Earth orbit satellite has completed forwarding the power grid fault information corresponding to the higher priority data forwarding priority.

[0070] After the data forwarding delay time period is completed, power grid fault information with a lower priority than higher priority data forwarding information is sent to the target low-Earth orbit satellite. At the same time, the data forwarding delay time period corresponding to the power grid fault information starts to start. After the data forwarding delay time period is completed, power grid fault information with an even lower priority is sent to the target low-Earth orbit satellite for forwarding processing, and its corresponding data forwarding delay time period starts to start, until all power grid fault information is forwarded by the target low-Earth orbit satellite.

[0071] For example, an electronic device acquires two power grid fault information messages. The data forwarding priority of the first power grid fault information message is higher than that of the second. The electronic device sets a first data forwarding delay time period for the first power grid fault information message and a second data forwarding delay time period for the second power grid fault information message. When the electronic device forwards the first power grid fault information message to the target low-Earth orbit satellite, the first data forwarding delay time period begins to count down. During the counting down, the electronic device sends the first power grid fault information message to the target low-Earth orbit satellite. The target low-Earth orbit satellite influences the first data forwarding command and forwards the first power grid fault information message to the master control terminal. When the first data forwarding time period completes, the electronic device forwards the second power grid fault information message to the target low-Earth orbit satellite. At this time, the second data forwarding delay time period begins to count down. During the counting down, the electronic device forwards the second power grid fault information message to the target low-Earth orbit satellite. The target low-Earth orbit satellite responds to the first data forwarding command and forwards the second power grid fault information message to the master control terminal.

[0072] In step S101, before acquiring at least two power grid fault information, the method further includes: acquiring the data resource quantity of the target low-orbit satellite; comparing the data resource quantity with the preset data resource quantity; and acquiring at least two power grid fault information if the data resource quantity is greater than the preset data resource quantity.

[0073] In some embodiments, the target low-Earth orbit satellite needs to forward power grid fault information while also forwarding multiple power grid terminal video data and operational data to the main control terminal in real time. Therefore, when a power grid terminal fault occurs, in the process of determining the priority of power grid fault information and forwarding it, it is necessary to consider whether the data resource volume of the target low-Earth orbit satellite at this time can support the forwarding of multiple power grid fault information. The electronic device obtains the data resource volume of the target low-Earth orbit satellite at the current moment and compares the data resource volume with the preset data resource volume. The preset data resource volume can be subjectively set by technicians based on the amount of data that the target low-Earth orbit satellite needs to transmit in real time. When the electronic device determines that the data resource volume is greater than the preset data resource volume, it obtains at least two power grid fault information and determines the data forwarding priority of subsequent power grid fault information and forwards the power grid fault information data.

[0074] In some embodiments, the preset data resource amount is the amount of data resources required to simultaneously transmit fault information generated when all grid terminals in a single-chain grid transmission line within the target grid area experience a fault, in order to improve the efficiency of forwarding multiple grid fault information.
