[0002] With the continuous expansion of the scale of power systems and the improvement of their intelligence levels, the equipment and communication nodes in the power communication transmission network are becoming more and more complex. At this time, the operation and maintenance of the power communication transmission network is becoming more and more difficult. Therefore, this application proposes a method for assisting the operation and maintenance of a power communication transmission network.

[0003] Prior art, such as the invention application patent with announcement number: CN117408669A, discloses an auxiliary method for operation and maintenance of a power communication transmission network, including: obtaining operation data and preprocessing, obtaining a first indicator set and a second indicator set; obtaining a first weight set corresponding to the first indicator set and a second weight set corresponding to the second indicator set; analyzing the first indicator set based on the support capability analysis rule and the first weight set to obtain a support capability score; analyzing the second indicator set based on the reliability analysis rule and the second weight set to obtain a reliability score; determining the power communication transmission network score through weighted summation based on the support capability score and the reliability score; formulating and executing improvement measures based on the relationship between the power communication transmission network score and the score threshold, and outputting a communication transmission network score report. By analyzing the support capability and reliability of the communication transmission network, the network transmission efficiency of the communication transmission network can be significantly improved.

[0004] Regarding the above scheme, there are the following technical problems: 1. The current technology lacks analysis of each transmission node in the power communication transmission network, and is unable to determine the specific fault location, resulting in the inability to carry out targeted operation and maintenance of the power communication transmission network, which in turn leads to reduced operation and maintenance efficiency and waste of resources, thus causing considerable economic losses to various industries.

[0005] 2. The current technology lacks analysis of the operation and maintenance priorities of each faulty transmission node, and thus cannot reasonably allocate resources, nor can it handle various power failures in a timely manner; at the same time, the current technology also lacks further analysis of each faulty transmission node after the operation and maintenance is completed. The current technology ignores this level, resulting in the inability to optimize and adjust each faulty transmission node in a timely manner after the operation and maintenance is completed, which is not conducive to improving the work efficiency and work quality of the subsequent power communication transmission network, nor is it conducive to the long-term sustainable development of the power communication transmission network. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Reference Figure 1 As shown, the present application provides a power communication transmission network operation and maintenance assistance method, comprising the following steps: Step 1, data detection: detecting the power data of each transmission node and the working data of each transmission link.

[0034] The specific process of detecting the power data of each transmission node and the working data of each transmission path is as follows: S1. When the power generation equipment generates power data, it is recorded as each power data, and the power transmission path with the shortest distance between the power generation equipment and the terminal equipment is obtained from the power communication transmission network, and each transmission node in the transmission path is obtained, and each transmission node is substituted into the node capacity model, and the capacity characteristic value of each transmission node is output. The capacity characteristic value contains data of -1 and 1. When the capacity characteristic value of a transmission node is 1, it is recorded as a transmission node, and the power data is transmitted through the node. When the capacity characteristic value of a transmission node is -1, it is not recorded as a transmission node, and the power data is not transmitted through the node.

[0035] S2. Obtain the adjacent node with the smallest straight-line distance to a transmission node with a capacity characteristic value of -1, record it as the first transit node, and obtain the capacity characteristic value of the first transit node. When the network characteristic value of the first transit node of the transmission node is 1, the first transit node replaces the transmission node. When the network characteristic value of the first transit node of the transmission node is -1, obtain the adjacent node with the second smallest straight-line distance to the transmission node and repeat the above steps until all transit nodes are replaced.

[0036] S3. Use the transmission path formed by the replaced transmission nodes as the first transmission path between the power generation device and the terminal device.

[0037] S4. Detect the transmission power of each transmission node in the first transmission path in the current cycle, and record it as the power data of each node; detect the delay and bandwidth utilization of the transmission link between each transmission node in the first transmission path in the current cycle, and record it as the working data of the transmission link between each transmission node.

[0038] It should be noted that power generation equipment includes thermal power generation equipment, wind power generation equipment, hydropower generation equipment and solar power generation equipment, etc.

[0039] It should be noted that terminal equipment includes hub substations in power grids, core computer rooms in communication networks, and distribution boxes in residential communities.

[0040] It should be noted that the power data and link working data of each node in each transmission path are uniformly detected by the regional power grid dispatching center, and the shortest transmission path between the power generation equipment and the terminal equipment is also obtained from the regional power grid dispatching center.

[0041] It should be noted that the expression of the node capacity model is Among them i represents the capacity characteristic value of the transmission node numbered i, y i represents the total amount of electricity that needs to be transmitted through the transmission node numbered i, y max Indicates the maximum amount of power allowed to pass through the transmission node.

[0042] It should be noted that the maximum amount of electricity allowed to pass through the transmission node is uniformly set by the regional power grid dispatching center.

[0043] It should be noted that when the capacity characteristic value of the transmission node is 1, it indicates that the transmission capacity of the transmission node has not reached the upper limit and transmission can continue; when the capacity characteristic value of the transmission node is -1, it indicates that the transmission capacity of the transmission node has reached the upper limit and transmission cannot continue.

[0044] Step 2: Fault analysis: Perform fault analysis based on the detected power data of each transmission node and the working data of the transmission link between each transmission node, and then obtain each faulty transmission node and determine the fault level.

[0045] In a specific example, the fault analysis of each transmission node is performed to obtain each faulty transmission node. The specific process is as follows: based on the power data in the current detection cycle, the transmission power of each transmission node at each detection time point is extracted, and the working evaluation coefficient δ of each transmission node is obtained by analysis. i .

[0046] Based on the working data of the transmission links between each transmission node in the current detection cycle, the bandwidth utilization and delay of the transmission links between each transmission node at each detection time point are extracted, and the working evaluation coefficient δ′ of each transmission link is obtained by analysis. i .

[0047] Based on the stability evaluation coefficient of each transmission node and the working evaluation coefficient of each transmission link, according to the calculation formula Analyze and obtain the fault assessment coefficient of each transmission node Wherein, i is the number of each node, i=1, 2, ... n, a1 and a2 represent the weight factor corresponding to the working evaluation coefficient and the weight factor corresponding to the working evaluation coefficient of the transmission link, respectively.

[0048] The fault assessment coefficient of each transmission node is compared with the transmission node fault assessment coefficient threshold. If the fault assessment coefficient of a transmission node is greater than or equal to the transmission node fault assessment coefficient threshold, the transmission node is judged to have a fault and the transmission node is recorded as a faulty node; otherwise, the node is judged to have no fault and the transmission node is recorded as a non-faulty node; accordingly, each faulty transmission node and each non-faulty node are obtained.

[0049] It should be noted that the detection cycle is a period of time during which the power supply is stable and unchanged. The specific length of the cycle is determined by the staff, such as three hours or six hours.

[0050] It should be noted that the working evaluation coefficient of the transmission link between the i-th transmission node and the i-1-th node is denoted as δ′ i .

[0051] It should be noted that 0<a1<1, 0<a2<1, a1+a2=1.

[0052] It should be noted that the weight factors corresponding to the working evaluation coefficients of the nodes and the weight factors corresponding to the working evaluation coefficients of the transmission links between the nodes are obtained by the factor analysis method. First, the information of the spatial path attenuation of the working evaluation coefficients of each node and the working evaluation coefficients of the transmission links between the transmission nodes is condensed, and then the variance explanation rate after rotation is obtained, and the weight is obtained by dividing the cumulative variance explanation rate.

[0053] It should be noted that factor analysis is a well-known technology. It is a multivariate statistical analysis method that starts from studying the internal dependencies of variables and reduces some variables with intricate relationships to a few comprehensive factors; information concentration is expressed as calculating the median; the variance explanation rate is the amount of information extracted by the factor, and the variance explanation rate = characteristic root / total number of analysis items; the variance explanation rate after rotation is expressed as the variance explanation rate of the factor after maximum variance rotation.

[0054] It should be noted that the transmission node fault assessment coefficient threshold is the minimum value of the historical transmission node fault assessment coefficient.

[0055] In a specific example, the analysis obtains the working evaluation coefficient of each transmission node. The specific analysis process is as follows: the transmission power of each transmission node at each detection time point in the current detection cycle is Q iv , where v represents the number of each detection time point in the current cycle, v = 1, 2, ... k, according to the calculation formula: The work evaluation coefficient δ of each transmission node is obtained by analysis i , where k is the total number of detection time points in the current cycle, Q i(v-1)is the transmission power of the transmission node numbered i at the v-1th detection time point in the current cycle.

[0056] In a specific example, the analysis obtains the working evaluation coefficient of the transmission link between each transmission node. The specific analysis process is as follows: the bandwidth utilization rate and delay of the transmission link between each transmission node at each detection time point in the current detection cycle are respectively recorded as G iv and R iv , according to the calculation formula: The working evaluation coefficient δ′ of each transmission link in the current cycle is obtained by analysis i , where G i(v-1) and R i(v-1) They respectively represent the standard value of bandwidth utilization and the standard value of delay of the transmission link between each transmission node.

[0057] In a specific example, the level of each faulty transmission node is determined, and the specific process is as follows: the position of each faulty transmission node is determined based on the fault assessment coefficient of each transmission node obtained by analysis, when a transmission node fails, the node with the shortest distance from the faulty node is obtained, recorded as and the auxiliary node of the faulty node is substituted into the node capacity model, when the capacity characteristic value of the auxiliary node is 1, the auxiliary node is used to replace the faulty transmission node for power transmission, and the faulty transmission node is recorded as a secondary faulty transmission node; when the capacity characteristic value of the auxiliary node is -1, the auxiliary node is not used to replace the faulty transmission node for power transmission, and the faulty node is recorded as a primary faulty transmission node; accordingly, each secondary faulty transmission node and each primary faulty transmission node are obtained.

[0058] It should be noted that the auxiliary node of each faulty transmission node is a node outside the first transmission path.

[0059] Step 3: Operation and maintenance plan analysis: Determine the operation and maintenance priority of each faulty transmission node based on its fault level and the number of connected terminal devices, and then formulate an operation and maintenance plan and perform resource scheduling.

[0060] In a specific example, the operation and maintenance priority of each faulty transmission node is determined according to the level of each faulty transmission node and the number of connected terminal devices. The specific process is as follows: the number of terminal devices connected to each secondary faulty transmission node F is obtained. i , and use the fault assessment coefficient of each secondary fault transmission node Substitute into the calculation formula: The operation and maintenance priority index χ of each secondary fault transmission node is obtained by analysis i ,in is the transmission node fault assessment coefficient threshold, ψ1 and ψ2 are the weight factors corresponding to the fault assessment coefficient of the secondary faulty transmission node and the weight factors corresponding to the number of terminal devices connected to the faulty node, respectively.

[0061] The operation and maintenance priority index of each secondary fault node is obtained, substituted into the operation and maintenance evaluation model, and the operation and maintenance characteristic value of each faulty transmission node is output. The operation and maintenance characteristic value contains data of -1 and 1. When the operation and maintenance characteristic value of a faulty transmission node is 1, the faulty transmission node is recorded as a primary operation and maintenance fault point, otherwise it is recorded as a secondary operation and maintenance fault point; and each primary faulty transmission node is recorded as a primary operation and maintenance fault point; accordingly, each primary operation and maintenance fault point and each secondary operation and maintenance fault point are obtained.

[0062] It should be noted that the more terminal devices the faulty transmission node is connected to, the more important the faulty transmission node is.

[0063] It should be noted that 0<ψ1<1, 0<ψ2<1, ψ1+ψ2=1.

[0064] It should be noted that the setting method of ψ1 and ψ2 is the same as that of a1 and a2, so it will not be repeated here.

[0065] It should be noted that the expression of the operation and maintenance evaluation model is in represents the operation and maintenance characteristic value of each secondary fault transmission node, χ i represents the operation and maintenance priority index of each secondary fault transmission node, χ max Indicates the threshold of the operation and maintenance priority index of the secondary fault transmission node.

[0066] It should be noted that the operation and maintenance priority index of each historical secondary fault node is obtained from the regional power grid dispatching center, and the median is taken as the threshold of the operation and maintenance priority index of the secondary fault transmission node after normal distribution.

[0067] In a specific example, the operation and maintenance plan is formulated and resources are scheduled. The specific process is as follows: for each first-level operation and maintenance fault point, an operation and maintenance team composed of various professionals is formed, and various operation and maintenance equipment and tools are equipped. The professionals are assessed regularly and various equipment and tools are inspected and repaired. When operating and maintaining the first-level operation and maintenance fault point, three or more professionals are required to work together.

[0068] For each secondary operation and maintenance fault point, an operation and maintenance team composed of staff with operation and maintenance experience is formed, and equipped with various operation and maintenance equipment and tools. Relevant staff members take turns on duty. When performing operation and maintenance on the secondary operation and maintenance fault point, one or more staff members are required to work together.

[0069] It should be noted that professionals include electrical engineers, power communication engineers and high-voltage engineers, etc.

[0070] It should be noted that various types of operation and maintenance equipment and tools include multimeters, oscilloscopes, high-voltage generators and relay protection testers.

[0071] It should be noted that staff with operation and maintenance experience refers to staff who have participated in first-level operation and maintenance or second-level operation and maintenance work.

[0072] Step 4: Node optimization: After the operation and maintenance is completed, optimize each faulty transmission node.

[0073] In a specific example, after the operation and maintenance is completed, each faulty transmission node is optimized. The specific optimization process is as follows: B1. For each secondary faulty transmission node, its historical fault count and the straight-line distance from the corresponding auxiliary node are obtained, and the optimization evaluation coefficient γ of each faulty transmission node is obtained through comprehensive analysis. i , and substitute it into the node optimization model to analyze and obtain the optimized characteristic value of each faulty transmission node. The optimized characteristic value contains two data, 1 and -1. When the optimized characteristic value of a faulty transmission node is 1, the faulty transmission node is optimized and the faulty transmission node is recorded as a secondary fault point to be optimized. When the optimized characteristic value of a fault point is -1, the faulty transmission node is not optimized and the fault point is recorded as a secondary normal fault point. For each primary faulty transmission node, it is optimized and recorded as each primary node to be optimized. Based on this, each secondary faulty transmission node to be optimized, each secondary normal fault node and each primary fault point to be optimized are obtained.

[0074] B2. For each secondary fault point to be optimized, each auxiliary node is updated to the corresponding transmission node, and each transmission node is updated to each auxiliary node; for each primary fault point to be optimized, a transmission node with a node capacity characteristic value of 1 is added at the position of its corresponding auxiliary node, and it is updated to the auxiliary node of the corresponding faulty transmission node.

[0075] It should be noted that the auxiliary node numbered as the i-th fault transmission node is recorded as the i-th auxiliary node.

[0076] It should be noted that the expression of the node optimization model is where θ i represents the optimized eigenvalue of each secondary fault transmission node, γ i represents the optimization evaluation coefficient of each secondary fault transmission node, γ max Indicates the threshold of the optimization evaluation coefficient of the secondary fault transmission node.

[0077] It should be noted that the threshold of the optimization evaluation coefficient of the secondary fault transmission node is the minimum value of the optimization evaluation coefficients of each secondary fault node in history.

[0078] In a specific example, the comprehensive analysis obtains the optimized evaluation coefficient γ of each faulty transmission node: iThe specific process is as follows: the number of historical failures of each secondary fault transmission node and the straight-line distance from the corresponding auxiliary node are recorded as Z i and T i , according to the calculation formula:

[0079] The optimized evaluation coefficient of each faulty transmission node is obtained by analysis, where Z′ and T′ represent the standard value of the number of failures of the faulty transmission node and the standard value of the distance from the corresponding auxiliary node, respectively, and b1 and b2 represent the weight factor corresponding to the historical number of failures of the faulty node and the weight factor corresponding to the distance from the corresponding auxiliary node, respectively.

[0080] It should be noted that the number of failures of each transmission node is obtained from the regional power grid dispatching center, and the median of each failure number is normally distributed as the standard value of the secondary failure transmission node. Similarly, the standard value of the distance between the secondary failure transmission node and its corresponding auxiliary node is obtained.

[0081] It should be noted that 0<b1<1, 0<b2<1, b1+b2=1.

[0082] It should be noted that the setting method of b1 and b2 is the same as that of a1 and a2, so it will not be repeated here.
