Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a method for modeling and terminal designing a flat-emergency-satellite-ground fusion communication network for wide-area monitoring of power transmission line corridors and related devices. Background Art

[0002] Transmission line corridors span vast areas and are exposed to complex and changing natural environments for a long time. They face the dual threats of extreme weather and human damage, and have serious safety hazards. Real-time and effective monitoring is essential to ensure the stability of the power system and prevent power failures. However, due to the long span of the transmission line, the communication performance along the line is uneven, and there is even a large part of the transmission corridor area without communication network coverage. Transmission line corridors often face problems such as missing network signals or unstable communication quality due to geographical location or environmental climate restrictions, resulting in the inability to timely transmit the monitoring results of the transmission line corridor. Especially in emergency situations, communication security is often difficult to ensure.

[0003] Due to the long span of transmission lines, the public network often has large communication blind spots, limited data transmission capacity, and data security faces great risks. Building a dedicated power network often requires a large investment and needs to be well protected against various harsh natural conditions along the transmission line. The investment and maintenance costs are huge. Existing communication technologies make it difficult to achieve full coverage of transmission line communications. When a line fails, the key monitoring data of the line cannot be transmitted back to the data center in time, and corresponding emergency measures cannot be taken in time. The current transmission line corridor monitoring communication has high deployment costs, unstable data transmission, and the inability to guarantee communication quality in extreme weather and complex environments, resulting in the inability to achieve comprehensive coverage of transmission line corridor communications and the inability to transmit key data in time in emergency situations.

[0075] The embodiment of the present invention provides a method for modeling and designing a terminal for a flat-emergency integrated satellite-ground fusion communication network for wide-area monitoring of a transmission line corridor, referring to Figure 2 , Figure 2 The present invention is a flow chart of the first embodiment of the method for modeling and terminal design of a ground-to-plane, emergency-integrated satellite-ground fusion communication network for wide-area monitoring of power transmission line corridors.

[0076] In this embodiment, the method for modeling and terminal design of a flat-emergency integrated satellite-ground fusion communication network for wide-area monitoring of transmission line corridors includes the following steps:

[0077] Step S10: determining the line importance level of each transmission line in the transmission line corridor based on the tower position of each node in the transmission line corridor.

[0078] It should be understood that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a terminal electronic device capable of realizing the above functions, etc. The following takes the modeling and terminal design device of the integrated satellite-ground fusion communication network for wide-area monitoring of the transmission line corridor (hereinafter referred to as the design device) as an example to illustrate this embodiment and the following embodiments.

[0079] It should be noted that the node is a data aggregation node of a tower in the transmission line corridor.

[0080] In some embodiments, a data aggregation terminal is installed on each transmission tower, which aggregates sensor data on the periphery of the tower and half of the length of the line on both sides connected to the next tower to a aggregation node.

[0081] In some embodiments, data from the aggregation node can be sent to a central node, which can refer to a node that can aggregate the data from the aggregation node and transmit it directly back to a data center, that is, a node connected to a satellite terminal or a cellular network or a node close to a substation and connected to a fiber optic network.

[0082] It can be understood that, in this embodiment, the importance of the area where each transmission line is located can be analyzed based on the tower position of each node in the transmission line corridor, and the line importance level of the transmission line can be evaluated based on the analysis result.

[0083] In some embodiments, the design equipment can deploy a convergence node on each tower of the transmission line. The sensor data around each tower and the sensor data on the long lines on both sides of the tower are converged to this node through wired and wireless local area networks (WiFi, Bluetooth, Zigbee, etc.). The convergence node transmits the converged data back to the data center through the satellite-ground fusion network designed by the present invention. Figure 3 , Figure 3 The schematic diagram of the satellite-ground integrated communication network architecture of the transmission line corridor is shown in the figure, wherein the substations are connected with a central node and multiple aggregation nodes, the aggregation node sends data to the central node, and the central node exchanges data with the communication satellite, wherein the communication satellite is a low-orbit satellite, and the central node and the low-orbit satellite establish a low-orbit satellite Internet communication connection to realize communication and data transmission between the central node and the low-orbit satellite. The low-orbit satellite Internet communication greatly improves the data transmission efficiency and effectively reduces the transmission delay. The low-orbit satellite transmits the data sent by the central node to the satellite base station, and the satellite base station transmits the data to the data center. The substation and the aggregation node can communicate and exchange data through optical fiber, and the substation and the aggregation node can communicate with the data center through cellular network through cellular base stations. The aggregation nodes can jump and transmit through self-organizing networks, thereby realizing low-orbit satellite Internet communication in the transmission line corridor, achieving full coverage of the communication range, greatly improving communication quality and communication efficiency, and effectively avoiding the problem of communication blind spots.

[0084] In some embodiments, due to the chain structure of the transmission line, the deployment cost of wireless ad hoc network communication is relatively low. Therefore, a wireless ad hoc network node module is deployed at each node in the network. According to the node network coverage, the nodes are mainly divided into the following categories: Class A nodes (no cellular network coverage and no satellite terminal deployed), Class B nodes (no cellular network coverage but satellite terminal deployed), C (cellular network coverage but no satellite terminal deployed), D (cellular network coverage and satellite terminal deployed), E (optical fiber network deployed and cellular network coverage).

[0085] In some embodiments, to ensure high reliability, the data transmission of each aggregation node must rely on at least two independent links. If a link fails, the backup link can immediately take over the data transmission to ensure uninterrupted communication. For line areas with higher importance levels, backup aggregation nodes should be deployed to ensure that redundant links in key areas are available. Redundant link design should consider physical isolation and multi-path routing to avoid single point failures affecting the entire system. At the same time, combined with an intelligent routing mechanism, it supports automatic switching of the optimal path when a link fails to ensure high availability of the network.

[0086] Step S20: performing priority analysis on the monitoring data of each transmission line to obtain the data transmission level corresponding to each monitoring data.

[0087] In a specific implementation, the design device can divide the monitoring data into multiple levels to evaluate the transmission priority of different monitoring data.

[0088] In some embodiments, the design device can use the hierarchical analysis method to quantitatively analyze the priority of the monitoring data of the transmission line and set different priorities for the data. A hierarchical structure model is set with the monitoring data weight as the target layer, the priority as the indicator layer, and the specific monitoring data as the solution layer, and a judgment matrix is ​​constructed. Finally, the priority weight of the monitoring data transmission is obtained by calculating the judgment matrix. For example, the data is generally divided into three levels: the first level, the second level, and the third level.

[0089] Among them, the first level is data that has extremely high time delay requirements and can directly affect the safety of the power grid, including alarm data of key line faults, environmental parameters reflecting abnormal surrounding environment, etc. For example: abnormal insulator leakage current data, abnormal tower inclination data, abnormal temperature data, abnormal wind speed data, etc.

[0090] The second level is data that has high latency requirements and is of great support to the normal operation of the power grid, including environmental monitoring data and periodic status inspection data, such as line temperature and humidity data, line tension data, insulator tension data, etc.

[0091] The third level is data with lower latency requirements, including low-frequency updated data and non-critical status data, such as data logging, transmission line icing monitoring data except for extreme weather and specific seasons, etc.

[0092] Step S30: Acquire emergency communication resource demand information of the transmission line corridor based on the data transmission level and the line importance level.

[0093] It should be noted that in order to achieve key data communication guarantee closely related to line fault monitoring when the transmission corridor fails or the environment is relatively bad, satellite Internet is used as an emergency network backup network guarantee, and satellite terminals are installed at the points where the importance of the line reaches a certain threshold. The satellite terminal can be a satellite Internet terminal, which can communicate and interact with different types of orbital satellites, including low-orbit satellites, medium-orbit satellites and high-orbit satellites. When the line is in a fault, the highest level of data return must be guaranteed; when the risk is high, the highest and second-level data return must be guaranteed.

[0094] Step S40: Generate a communication resource configuration strategy for the transmission line corridor according to the line importance level, the data transmission level and the emergency communication resource demand information.

[0095] It should be noted that the communication resource configuration strategy can be a strategy for configuring the communication mode of different nodes in the transmission line corridor. For example, the design equipment can select the most suitable communication mode according to the communication needs of nodes at different locations to ensure the efficiency and stability of data transmission. The above communication modes may include wireless multi-hop forwarding communication, satellite terminal communication, cellular network communication and optical fiber transmission communication between nodes. The above satellite terminal communication can be to configure a satellite terminal for the node. The satellite Internet terminal can communicate and interact with different types of orbital satellites, including low-orbit satellites, medium-orbit satellites and high-orbit satellites.

[0096] It can be understood that this embodiment generates a communication resource configuration strategy to achieve reasonable configuration of communication resources, configures a corresponding communication mode for each node in the transmission line corridor, for example, provides low-orbit satellite communications for remote areas and areas with harsh climates, thereby ensuring emergency communication needs, and provides wireless multi-hop forwarding communications and / or cellular network communications for areas with comprehensive network coverage, thereby reducing communication costs.

[0097] In some embodiments, for core data transmission near substations or between key nodes, optical fiber communication can be used because of its advantages of low latency and high bandwidth, but the cost is relatively high; in areas with relatively complete ground communication infrastructure, cellular networks can be selected to support the transmission of medium-frequency data traffic, but communication blind spots must be avoided. For emergency communication needs in remote areas and in harsh climates, low-orbit satellite Internet provides wide coverage and high stability, with lower latency and higher bandwidth than traditional geostationary satellites.

[0098] It should be noted that in remote areas with insufficient network coverage, wireless multi-hop self-organizing networks can transmit data at low cost through wireless multi-hop forwarding mechanisms between nodes, but the limited bandwidth has problems such as data accumulation and excessive delay. In view of the long span of the transmission line and the fact that the research object is the transmission line corridor in remote areas, in some embodiments, the fusion of wireless multi-hop self-organizing networks combined with low-orbit satellite Internet backhaul can be used as the main communication method in remote areas without signals, which can not only meet the low-cost communication needs, but also ensure the stability of the entire line communication and high-bandwidth backhaul capabilities.

[0099] Furthermore, in order to accurately and reasonably configure communication resources, the above step S40 may include:

[0100] Step S401: Analyze the delay of each communication mode to obtain communication delay information;

[0101] Step S402: generating a delay constraint condition based on the communication delay information;

[0102] Step S403: acquiring conventional communication resource demand information corresponding to each node according to the tower position of each node, the line importance level and the data transmission level;

[0103] Step S404: Generate a communication resource configuration strategy for the transmission line corridor according to the delay constraint condition, the conventional communication resource demand information and the emergency communication resource demand information.

[0104] It should be noted that the communication delay information includes multi-hop transmission delay information of power transmission lines, satellite Internet delay information, cellular network delay information and optical fiber data transmission delay information.

[0105] It should be noted that the delay constraints may include:

[0106] ;

[0107] in, It indicates the time it takes for node data to be transmitted back to the data center through the communication link. Represents a judgment node The binary variable of the data transmission status. Data transmission through the link ( ) is 1, otherwise it is 0. Indicates the maximum delay requirement.

[0108] In the specific implementation, the design equipment can analyze the delay information of different communication modes respectively. The delay analysis may include the delay analysis of multi-hop transmission of power lines, the delay analysis of satellite Internet, the delay analysis of cellular networks and the delay analysis caused by optical fiber data transmission.

[0109] In some embodiments, the delay analysis of multi-hop transmission of the transmission line may include: assuming that the transmission line has The amount of data collected by each node is , the time each node spends accessing the channel is , the amount of data transmitted by the node Data collected for itself Data transmitted from adjacent nodes The sum of the local data is placed on the top of the stack. The transmission rate is ,node The latency back to the data center is , if the deployment of cellular network and satellite terminal is not considered, the maximum delay of the node in the middle is:

[0110] ;

[0111] In some embodiments, satellite Internet delay analysis: when a node transmits data to a node with a satellite terminal and transmits it back to a data center via satellite Internet, the main delays include four parts, namely, the delays generated during the multi-hop transmission from the node to the node with a satellite terminal. , satellite uplink transmission delay , satellite downlink transmission delay , the total delay of on-board processing and the delay of the ground signal station transmitting data to the data center , refer to the following formula:

[0112] ;

[0113] in, is the number of hops from the node to the satellite terminal, It is the delay generated during multi-hop transmission from the node to the terminal node with satellite.

[0114] ;

[0115] in, is the satellite uplink transmission delay, is the amount of uplink data, is the rate at which new data is uploaded from the satellite terminal. is the distance from the satellite to the ground base station, The speed of light.

[0116] ;

[0117] in, is the satellite downlink transmission delay, is the amount of downlink data, is the bandwidth of satellite data downlink, is the distance from the satellite to the ground base station, The speed of light.

[0118] In some embodiments, the delay analysis of the cellular network may include: if the conditions for deploying cellular base stations in some areas of the transmission line are good, cellular base stations can also be deployed along the line, and the node data can be transmitted back by the cellular network. The delay of the cellular network is mainly composed of three parts: the delay required for the node to transmit to the nearest node within the coverage area of ​​the cellular network. , cellular network transmission delay , the latency of the cellular base station transmitting data back to the data center .

[0119] ;

[0120] in, The amount of data transmitted over the cellular network, The data transmission rate of the cellular network.

[0121] In some embodiments, the delay analysis caused by optical fiber data transmission may include: the node near the substation transmits data to the substation through optical fiber communication, and the substation packages the data and transmits it back to the data center. The delay mainly includes the delay caused by the data transmission through optical fiber. , the delay of substation data packaging and processing , the latency of the substation transmitting data to the data center .

[0122] In some embodiments, in order to accurately obtain the optimal configuration strategy, the above step S404 may include:

[0123] Step S4041: generating an optimization target according to the delay constraint condition, the conventional communication resource demand information and the emergency communication resource demand information;

[0124] Step S4042: constructing an optimization model based on the optimization target;

[0125] Step S4043: obtaining multiple candidate resource configuration strategies according to the optimization model;

[0126] Step S4044: obtaining the attribute fuzzy weight of the transmission line corridor;

[0127] Step S4045: performing information entropy weight analysis on each candidate resource allocation strategy based on the attribute fuzzy weight to obtain uncertainty quantification parameters of each candidate resource allocation strategy;

[0128] Step S4046: Filter out a communication resource configuration strategy from the candidate resource configuration strategies according to the uncertainty quantification parameter.

[0129] It is understandable that the design equipment can be based on the communication resource deployment method of the multi-objective particle swarm algorithm. Since the transmission line corridor has a chain structure and a very long span, the main way is to deploy a wireless multi-hop network in a nearly straight line through the Internet of Things technology to achieve low-cost, long-endurance, and wide-coverage communication coverage. However, due to the bandwidth limitations of the wireless multi-hop network and the need to complete multiple relays, a large amount of data backlog will be generated, and the transmission delay cannot meet the relevant requirements of the power system. Therefore, in this embodiment, a transmission network that integrates cellular networks, optical fiber networks, and satellite Internet can be selected.

[0130] It should be noted that the optimization objectives include delay optimization objectives, cost optimization objectives and power consumption optimization objectives. This embodiment can optimize the three objectives based on the node location, with the minimum overall network delay, minimum deployment cost and lowest power consumption as the goals, and with the conventional monitoring requirements of transmission line corridor data, emergency communication guarantee requirements, and the maximum delay requirements and maximum cost requirements of the power system for node data transmission as constraints, to obtain several suitable satellite terminal deployment strategies.

[0131] The optimization model includes a multi-objective particle swarm optimization algorithm model, which has N decision variables and 3 decision objectives as follows:

[0132] ;

[0133] in, The target vector representing the optimization objective, represents the constraints, represents a decision vector, wherein the decision vector is a parameter affecting the target vector, and the decision vector includes data transmission cost, data transmission speed and data transmission bandwidth, is the decision space of the decision vector, is the target space of the target vector.

[0134] In some embodiments, the design device can obtain multiple candidate resource configuration strategies through a multi-objective particle swarm optimization algorithm model, and select the most satisfactory deployment plan by using a fuzzy entropy weight Vague set multi-attribute decision-making method.

[0135] In some embodiments, the design device determines the fuzzy weight of the attribute, uses the information entropy weight to judge the objective weight, performs geometric averaging on the attribute fuzzy weight and the objective weight, calculates the comprehensive Vague value of the solution set, calculates the scoring function value of each candidate resource configuration strategy in the solution set, sorts the solutions of different candidate resource configuration strategies, selects the most appropriate solution, and obtains the communication resource configuration strategy.

[0136] Step S50: Generate a transmission resource configuration strategy based on the communication resource configuration strategy and the data transmission level.

[0137] It should be noted that the design equipment can configure the transmission priority of data of different levels in each node according to the data transmission level and communication resource configuration strategy. For example, a transmission method is designed to maximize the transmission of data with priority guarantee, and a CBS mechanism is designed based on data priority to ensure as much low-priority data transmission as possible while ensuring high-priority data transmission.

[0138] In some embodiments, the CBS mechanism design based on data priority can first ensure that high-priority data is transmitted as much as possible, and on the premise of ensuring that all data of the highest priority level is transmitted, ensure that the second-level data is transmitted as much as possible, and after all data of the second level is transmitted, maximize the transmission of other node data. Secondly, when high-priority data cannot be transmitted due to communication resource limitations, update the communication link capacity to ensure the transmission of low-priority data.

[0139] In some embodiments, in order to avoid to a certain extent the situation where low-priority data cannot obtain transmission resources for a long time and cannot be returned when communication network resources are damaged and communication resources are limited, CBS transmission management is performed based on data priority. While strictly queuing and transmitting according to the level, the second-level and lowest-level data are subjected to traffic shaping to ensure that part of the data of this level will be returned every certain time period.

[0140] Furthermore, in order to effectively allocate data transmission resources and ensure that key data can be transmitted in a timely manner, the above step S50 may include:

[0141] Step S501: grouping the transmission lines for data transmission based on the line positions of the transmission lines in the transmission line corridor to obtain grouping results;

[0142] Step S502: Generate a conventional data transmission strategy based on the data transmission level and the grouping result;

[0143] Step S503: performing analysis level analysis on each transmission line according to the pre-built line disaster risk analysis model to obtain the line risk level corresponding to each transmission line;

[0144] Step S504: generating an emergency data transmission strategy for the transmission line corridor based on the line risk level;

[0145] Step S505: Generate a transmission resource configuration strategy according to the communication resource configuration strategy, the conventional data transmission strategy and the emergency data transmission strategy.

[0146] It can be understood that this embodiment can group the line wireless multi-hop sensor network, build a multi-objective mathematical model based on the goals of minimum power consumption and minimum transmission cost, and design a globally optimal Lagrange multiplier search algorithm to obtain the optimal grouping transmission mechanism, and generate a regular data transmission strategy based on the grouping transmission mechanism, thereby ensuring the stability of daily data transmission.

[0147] It should be noted that multi-hop transmission of lines will cause data backlog and excessive delay. Therefore, the lines are divided into multiple groups according to the location of the central node configured on the line. Each group of data is directly transmitted back to the data center through the central node, which can effectively solve the problems of data backlog and excessive delay.

[0148] It is understandable that the design equipment can use deep learning network technology to build a line disaster risk analysis model, and divide the line monitoring level into three levels, namely low risk, high risk, and fault level. Establish a line disaster model library. The formation of fault disasters often manifests itself as a multi-chain causal relationship, with obvious hierarchical nature in time. By receiving various monitoring data from front-end equipment, calculating real-time data, and intelligently comparing and analyzing the calculation results with the regional disaster model library database, the changing trend of disasters faced by the transmission line area is obtained, and the risk level faced by the line is classified.

[0149] In some embodiments, the design device can design an adaptive routing algorithm based on link stability to achieve optimal path transmission of key data of the transmission line when the line fails or is at high risk, thereby generating an emergency data transmission strategy to ensure that key data can be transmitted in a timely and stable manner in an emergency.

[0150] Furthermore, in order to ensure stable transmission of critical data in emergency situations and improve the efficiency of emergency transmission response, the above step S504 may include:

[0151] Step S5041: obtaining the signal-to-noise ratio parameters of the nodes of each communication link in the transmission line corridor;

[0152] Step S5042: Acquire link availability information and data buffer information of each communication link;

[0153] Step S5043: construct a link reliability model based on the decision attributes of each communication link:

[0154] Step S5044: obtaining link quality parameters of each communication link according to the link reliability model;

[0155] Step S5045: Generate an emergency data transmission strategy for the transmission line corridor based on the link quality parameter and the line risk level.

[0156] It should be noted that the communication link is composed of more than one node. Since the environment between the node links is changing in real time, a certain transmission time passes when node i sends data to node j. The signal-to-noise ratio is calculated by referring to the following formula:

[0157] ;

[0158] in, Indicates the signal-to-noise ratio parameter when the node receives data. is the transmission power of the node, is the loss in the data propagation process, Indicates signal interference information.

[0159] It should be noted that the decision attributes include signal-to-noise ratio parameters, link availability information and data buffer information. The real-time perceived signal-to-noise ratio, link availability and data buffer queue status are selected as decision attributes to obtain a link reliability model, and the link quality parameters are calculated by referring to the following formula.

[0160] ;

[0161] in, is the number of decision attributes, The weight assigned to each decision attribute, Indicates The utility value of an attribute, It represents the link quality parameter, and the adaptive maximum deviation algorithm is introduced to determine the attribute weights of each dynamic link.

[0162] In some embodiments, after the design device obtains the link quality based on the dynamic link reliability model and the adaptive weight calculation, the adaptive routing algorithm is designed to continuously select the best link as the channel.

[0163] It can be understood that the design equipment can quantify the performance of the wireless link by defining the link reliability, establish a dynamic link reliability model to evaluate the link quality, introduce the weights of each parameter in the maximum deviation algorithm adaptive calculation modeling to consider the transmission differences between different communication network links, form a multi-attribute routing decision problem, and select the link with the highest reliability as the transmission path.

[0164] Step S60: performing communication network modeling and terminal design for the transmission line corridor according to the communication resource configuration strategy and the transmission resource configuration strategy.

[0165] It should be noted that the communication network modeling can be to model the communication resource configuration of the transmission line corridor, so as to design the communication mode of the transmission line corridor. The above terminal design can be a hardware design scheme for the node communication terminal based on the communication network modeling.

[0166] In some embodiments, the hardware design of the node communication terminal may include:

[0167] Step 1: The power supply design of the communication terminal uses lithium batteries as the main power source. At the same time, each node is equipped with solar photovoltaic panels and lithium batteries to provide uninterrupted power supply for the node. The communication terminal uses three voltage levels of 12V, 5V, and 3.3V to power each internal module.

[0168] Step 2: Design of data receiving communication part. The communication terminal collects data from sensors deployed in the surrounding area through Zigbee, WIFI, and Bluetooth external antennas, and connects to the camera through RJ45 and the relevant power electronic sensor devices through RS485 to read the relevant monitoring data.

[0169] Step 3: Data backhaul communication design. The terminal’s data backhaul has corresponding interfaces for the self-organizing network module, 4G network, and low-orbit satellite Internet terminal. The controller can select the communication method for data backhaul. When the terminal is near the substation, the data in the memory is directly transmitted through the optical fiber interface.

[0170] Step 4: Design of the processing module of the communication terminal. The communication terminal deploys modules such as the adaptive routing algorithm bearer module, the data aggregation storage module, the module for storing the importance of the line, and the historical monitoring data storage module. It also has a multi-mode satellite positioning module. The functions required by the terminal are realized based on the RK3588 processor.

[0171] Step 5: Risk warning unit design, based on the data monitored by the sensor and the surrounding real scene monitored by the camera, set up a deep learning unit, perform target detection, target segmentation, and regional monitoring based on the YOLO algorithm, and make real-time perception of the risk level of the line based on the line disaster risk analysis model constructed by the present invention. At the same time, the perception results are transmitted to the data control module to realize the change of the data transmission mechanism, and sound and light alarms are detected when the line fails, so that the inspection personnel can find and repair it in time.

[0172] Step 6: Other peripheral settings. The communication terminal module design proposed in the present invention supports further optimization. The specific design can add or delete some interfaces and peripherals according to the specific environment characteristics and functional needs. The terminal can also be equipped with a host computer, buttons and debugging interfaces to achieve friendly interaction with the staff.

[0173] This embodiment determines the line importance level of each transmission line in the transmission line corridor based on the tower position of each node in the transmission line corridor, the node is a data aggregation node of the tower in the transmission line corridor, performs priority analysis on the monitoring data of each transmission line, obtains the data transmission level corresponding to each monitoring data, obtains the emergency communication resource demand information of the transmission line corridor based on the data transmission level and the line importance level, generates a communication resource configuration strategy for the transmission line corridor based on the line importance level, the data transmission level and the emergency communication resource demand information, generates a transmission resource configuration strategy based on the communication resource configuration strategy and the data transmission level, and performs communication network modeling and terminal design for the transmission line corridor based on the communication resource configuration strategy and the transmission resource configuration strategy; since this embodiment performs The importance level of the line and the data transmission level are quantified to evaluate the importance and priority of the transmission line and monitoring data, accurately and reasonably configure communication resources and data transmission resources, and configure communication resources and data transmission resources according to the importance level of the line, the data transmission level and the demand information of emergency communication resources, so as to effectively respond to the data transmission scenarios of emergency and routine situations, realize the integrated design of data transmission in peace and emergency, ensure the communication quality in extreme weather and complex environment, realize the timely transmission of key data in emergency situations, and reasonably configure the communication mode of the node based on the communication resource configuration strategy, so as to realize the comprehensive coverage of the corridor area of ​​the transmission line corridor communication on the basis of reasonable cost control, effectively avoid the communication blind spot problem of the transmission line corridor, and greatly improve the communication quality and data transmission efficiency of the transmission line corridor.

[0174] refer to Figure 4 , Figure 4 It is a flow chart of the second embodiment of the method for modeling and terminal design of a flat, emergency, satellite-ground fusion communication network for wide-area monitoring of transmission line corridors of the present invention.

[0175] Based on the above first embodiment, in this embodiment, step S10 further includes:

[0176] Step S101: quantifying the importance of each transmission line based on the tower position of each node in the transmission line corridor to obtain importance quantification parameters.

[0177] It is understandable that the importance of a transmission line is related to its position in the network. The power grid is equivalent to a network graph, and the centrality of the edge is quantified. The importance of a line can be determined by analyzing the change in centrality when a line is disconnected. The greater the change, the more important the line is in the network. The specific quantification formula is as follows:

[0178] ;

[0179] ;

[0180] in, Indicates the importance of the line in the line network. represents the identity matrix, Representation Node right The central contribution of represents the network feature matrix, and represents the network structure before and after the line is removed, represents the centrality in the equivalent network diagram of the power grid before and after the line is removed, and the centrality represents the importance of the line, and are model parameters, is the adjacency matrix of the power grid equivalent network graph.

[0181] Step S102: Quantitatively analyze the historical fault data of each transmission line to obtain quantitative parameters of the historical faults of each transmission line.

[0182] It should be noted that, in this embodiment, the possibility of line area failure is understood through quantitative analysis of line fault history data, which is used as a reference for subsequent communication resource configuration. The specific formula is:

[0183] ;

[0184] in, represents the quantitative parameter of historical faults, represents the historical fault occurrence rate of the line, is the scope of the impact of historical failures, and are the fault data weighting factors respectively.

[0185] Step S103: Quantitatively analyze the historical meteorological data of each transmission line to obtain the historical meteorological quantitative parameters of each transmission line.

[0186] It should be noted that this embodiment analyzes the frequency of extreme weather in the line area and the equipment failure caused by extreme weather to understand the threat level of regional meteorological conditions to line equipment. The specific formula is quantified as follows:

[0187] ;

[0188] in, is a historical meteorological quantitative parameter, is the frequency of extreme weather conditions in the area. The potential damage degree of the meteorological disasters in the area to the equipment can be obtained from the historical data of failures caused by previous meteorological disasters. and are the meteorological data weighting factors respectively.

[0189] Step S104: determining the line importance level of each transmission line in the transmission line corridor based on the importance quantification parameter, the historical fault quantification parameter and the historical meteorological quantification parameter.

[0190] It should be noted that the importance level of the area where the line is located is determined based on the importance of the line in the network, the analysis of the historical fault data of the line, and the meteorological conditions of the line. Line nodes with a certain importance level need to be equipped with satellite Internet terminals for emergency communication capacity backup, and at the same time deploy an appropriate number of backup aggregation nodes and appropriately increase the number of monitoring sensors. The importance level of the line can be expressed as:

[0191] ;

[0192] in, Indicates the importance level of the line. Indicates the importance of the line in the line network. represents the quantitative parameter of historical faults, is a historical meteorological quantitative parameter, , and Quantify the weight factor for the importance level.

[0193] This embodiment quantifies the importance of each transmission line based on the tower position of each node in the transmission line corridor, obtains importance quantification parameters, quantifies and analyzes the historical fault data of each transmission line, obtains the historical fault quantification parameters of each transmission line, quantifies and analyzes the historical meteorological data of each transmission line, obtains the historical meteorological quantification parameters of each transmission line, and determines the line importance level of each transmission line in the transmission line corridor based on the importance quantification parameters, the historical fault quantification parameters and the historical meteorological quantification parameters, thereby accurately quantifying the importance level of each transmission line, identifying the important lines in the transmission lines, thereby ensuring the stability of the communication quality of the important lines and reasonably allocating communication network resources.

[0194] In addition, an embodiment of the present invention also proposes a computer-readable storage medium, on which is stored a program for modeling and designing a flat, emergency, satellite-ground fused communication network for wide-area monitoring of transmission line corridors.
