Description

Technical Field

[0001] The present application relates to the technical field of power systems, and in particular, to a method, device, computer-readable storage medium, and electronic device for handling overload of the main line of a distribution network line. Background Technique

[0002] In the process of building a new power system, the distribution network line is an important access part for new distributed energy sources, charging piles, energy storage and other devices. At the same time, the distribution network line is directly responsible for supplying power to power users through distribution transformers. The safe and stable operation of the distribution network line plays an important role in the entire new power system.

[0003] Currently, for monitoring the load operation of the distribution network line, it is mainly through the distribution network master station system to monitor whether the load of the distribution network line exceeds the allowable current-carrying capacity. When the load of the distribution network line exceeds the current-carrying capacity, the distribution network dispatching agency ensures that the distribution network line does not operate over the current-carrying capacity by transferring the load or notifying the distribution network line operation and maintenance unit to control the load, providing support for ensuring the safe and stable operation of the distribution network line equipment.

[0004] Currently, when setting the current-carrying capacity of the distribution network line, the equipment management department mainly sets it based on the CT limit of the distribution network line substation, the rated load limit corresponding to the parameters of the outgoing cable equipment of the distribution network line, etc. Therefore, when the distribution network dispatching agency monitors the load of the distribution network line through the distribution network master station system, when the load of the distribution network line does not exceed the set current-carrying capacity of the distribution network line, it is defaulted that the distribution network line is operating safely and stably. However, in the actual operation process of the distribution network line, there is a problem that although the distribution network line does not exceed the current-carrying capacity of the distribution network line, the load of some line segments in the main line of the distribution network line has exceeded the rated load limit allowed by the line segment equipment itself, which may lead to long-term overload operation of the equipment and even equipment burnout, affecting the reliable supply of electricity and other situations.

[0032] In this embodiment, a method for handling overload of the main line of a power distribution network running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0033] Figure 2 is a flowchart of a method for handling overload of the main line of a power distribution network according to an embodiment of the present application. As Figure 2 shown, the method includes the following steps:

[0034] Step S201, calculate the annual maximum power supply load of the main line of the power distribution network, where the annual maximum power supply load represents the maximum annual power supply load of the main line under normal operation, and the power distribution network includes a main line and a non-main line.

[0035] Specifically, calculating the annual maximum power supply load of the main line of the power distribution network can determine the maximum load that the main line can withstand under normal operation, ensuring the safe and stable operation of the line.

[0036] Step S202, calculate the annual maximum power supply load of the tie line of the main line according to the annual maximum power supply load to obtain the tie line annual maximum power supply load, where the tie line represents a line that is directly connected to the main line.

[0037] Specifically, calculating the annual maximum power supply load of the tie line of the main line can determine the load-bearing capacity of the main line. By calculating the tie line annual maximum power supply load, the load distribution between the main line and the tie line can be discovered in time, so as to effectively plan and optimize the operation of the power distribution network, avoid the occurrence of main line overload, and ensure the stable operation of the power distribution system.

[0038] Step S203, determine whether the main line is operating in overload according to the tie line annual maximum power supply load. In the case where the main line is operating in overload, reconfigure the main line of the power distribution network to a value of the line load limit greater than the tie line annual maximum power supply load, where the line load limit represents the maximum load amount passing through the line segment.

[0039] Specifically, by determining whether the main line is operating in overload and configuring the main line with a line load limit greater than the tie line annual maximum power supply load as the main line of the power distribution network, the reasonable distribution and optimization of the main line load can be realized, avoiding main line overload, improving the power supply reliability and stability of the line, and at the same time effectively reducing the load pressure of the main line, extending the service life of the line, and ensuring the normal operation of the power distribution system.

[0040] Through the above embodiments, first calculate the annual maximum power supply load of the main line of the distribution network line. Among them, the annual maximum power supply load represents the maximum power supply load of the main line every year under normal operation. The distribution network line includes the main line and the non-main line. Then calculate the annual maximum power supply load of the connection line of the main line according to the annual maximum power supply load of the main line to obtain the connection power supply annual maximum load. Among them, the connection line refers to the line directly connected to the main line. Finally, determine whether the main line is overloaded according to the connection power supply annual maximum load. In the case that the main line is overloaded, reconfigure the main line of the distribution network line to a value where the line load limit is greater than the connection power supply annual maximum load. Among them, the line load limit represents the maximum load passing through the line segment. This application achieves the purpose of automatically counting the load conditions of each line segment of the main line of the distribution network line, comparing the load limit of the equipment itself, and analyzing whether the main line is overloaded. At the same time, it intelligently recommends the model of the transformation equipment for the overloaded line segment, thus achieving the technical effect of intelligent decision-making for automatically analyzing overloaded operation and equipment selection, improving the accuracy and efficiency of the system, and further solving the problem in the prior art that only the outgoing cable of the distribution network line can be monitored for overload, while the overload of the main line segment cannot be monitored, and manual parameter comparison and analysis are required, resulting in an incomplete monitoring range, low efficiency, and low accuracy.

[0041] Figure 3 is a flowchart of an optional method for dealing with the overload of the main line of the distribution network line according to the embodiments of the present application. As Figure 3 shown, statistically calculate the annual maximum power supply load of the main line segment of the distribution network line through the capacity conversion relationship, and then analyze and calculate the maximum load of the connection power supply of the main line segment of the distribution network line. Determine whether the main line segment of the distribution network line is overloaded through analysis and comparison, and output the line segment parameters for transformation according to the results.

[0042] In an optional solution, before calculating the annual maximum power supply load of the main line of the distribution network line, the above method further includes: obtaining the annual maximum load, capacity, and model of the distribution transformer in the distribution network line; obtaining the line load limit and cross-sectional area of the distribution network line, and obtaining the power supply path and connection line of the distribution network line. In this embodiment, obtaining the annual maximum load, capacity, and model of the distribution transformer can help determine whether the transformer meets the line load requirements. Obtaining the line load limit and cross-sectional area of the distribution network line can help evaluate the bearing capacity of the line and determine whether the line needs to be increased in capacity or upgraded. Obtaining the power supply path and connection line of the distribution network line can help determine the structure and power supply method of the line, help analyze the load conditions of the system, evaluate the bearing capacity of the line, and determine possible bottlenecks and problems, so as to formulate an effective overload handling plan to ensure the safe and stable operation of the system.

[0043] Figure 4It is a flowchart of another optional method for handling overload of the main line of a distribution network according to an embodiment of the present application. As Figure 4 shown, the data acquisition module acquires distribution network line, distribution transformer load, and equipment basic ledger data, acquires distribution network line load data based on the dispatching automation system, and acquires distribution transformer load data based on the metering automation system; at the same time, acquires cable and overhead equipment parameters based on the asset system, and acquires the connection relationship of the distribution network line through the asset system ledger.

[0044] Specifically, it is manifested as follows: 1) The asset system includes distribution transformer location information data. For the acquisition of distribution network line load data, the annual maximum load of the distribution network line is statistically obtained based on the distribution network line current data collected by the dispatching automation system every 15 minutes; 2) For the acquisition of distribution transformer load data of the distribution network line, the annual maximum load of the distribution transformer is statistically obtained based on the distribution transformer current data collected by the metering automation system every 15 minutes; 3) For the acquisition of distribution transformer parameter data of the distribution network line, the distribution transformer parameter data of the distribution network line is acquired based on the asset system; 4) For the acquisition of distribution network line segment parameter data, the cable and overhead line segment parameter information of the distribution network line is acquired based on the asset system; 5) For the acquisition of the power supply path and connection relationship data of the distribution network line, the distribution transformer situation and connection relationship data powered by the power supply path of the distribution network line are acquired based on the asset system, and data association is performed. The connection relationship is the data information of other distribution network lines directly connected to the distribution network line.

[0045] Optionally, the above distribution transformer parameter data may include, but is not limited to, parameters such as the capacity and model of the distribution transformer; the above distribution network line segment parameter data may include, but is not limited to, parameters such as the line segment load limit and line segment cross-sectional area.

[0046] According to some exemplary embodiments of the present application, calculating the annual maximum power supply load of the main line of the distribution network line includes: calculating the sum of the annual maximum loads of all distribution transformers in the distribution network line to obtain a first sum value; calculating the sum of the annual maximum loads of multiple distribution transformers on the main line of the distribution network line to obtain a second sum value; obtaining the annual maximum load of the distribution network line, calculating the ratio of the second sum value to the first sum value, and calculating the product of the ratio and the annual maximum load of the distribution network line to obtain the annual maximum power supply load of the main line. In this embodiment, by calculating the sum of the annual maximum loads of the distribution transformers and the sum of the annual maximum loads of multiple distribution transformers on the main line, the annual maximum power supply load of the main line can be determined. By comparing the annual maximum power supply load of the main line with the annual maximum load of the distribution network line, it can be judged whether there is an overload situation on the main line, so as to timely discover and handle the overload problem of the main line and ensure the safe and stable operation of the power grid.

[0047] As Figure 4As shown, after data association, the annual highest load analysis module for the normal operation mode of the main line segment of the distribution network line calculates the annual highest load of the main line segment of the distribution network line through the capacity conversion relationship based on the annual highest load of the entire distribution network line and the annual highest load data of the distribution transformers powered by the distribution network line.

[0048] Specifically, it is manifested as follows: 1) Statistical analysis of the load data of distribution transformers on the distribution network line. Based on the account data in the asset management system, analyze the distribution transformers powered by the entire distribution network line. At the same time, obtain the annual highest load of each distribution transformer from the metering automation system based on the distribution transformer account. Let there be M distribution transformers (i.e., distribution transformers) on the entire distribution network line, and L i be the annual highest load of the i-th distribution transformer. Then the sum of the annual highest loads of the distribution transformers on the distribution network line, L z (i.e., the first sum value) is: ; 2) Statistical analysis of the load data of the distribution transformers powered by the main line segment of the distribution network line. Based on the power supply path of the distribution network line obtained from the asset management system, analyze the distribution transformers powered by the main line segment of the distribution network line. At the same time, obtain the annual highest load of each distribution transformer from the metering automation system based on the distribution transformer account. Let there be N distribution transformers powered by the main line segment of the distribution network line, and L i be the annual highest load of the i-th distribution transformer. Then the sum of the annual highest loads of the distribution transformers powered by the main line segment of the distribution network line, L F (i.e., the second sum value) is: ; 3) Statistical analysis of the annual highest load of the main line of the distribution network line under normal operation mode. Based on the annual highest load data of the entire distribution network line obtained from the dispatching automation system, and at the same time, combining the calculated load data of the distribution transformers on the distribution network line and the load data of the distribution transformers powered by the main line segment of the distribution network line, obtain the annual highest load data of the main line segment of the distribution network line through capacity conversion. Let the annual highest load of the entire distribution network line be F Z (i.e., the annual highest load of the distribution network line). Then the annual highest load F F (i.e., the annual highest load of the main line) of the main line segment of the distribution network line under normal operation mode is: .

[0049] According to some exemplary embodiments of the present application, calculating the annual maximum load of the connecting line of the main line based on the annual maximum load of the power supply, and obtaining the annual maximum load of the connecting power supply, including: obtaining the annual maximum load of each connecting line, and determining the maximum annual maximum load as the annual maximum load of the connecting line; calculating the sum of the annual maximum load of the power supply and the annual maximum load of the connecting line, obtaining the coincidence factor, calculating the product of the sum of the annual maximum load of the power supply and the annual maximum load of the connecting line, and the coincidence factor, to obtain the annual maximum load of the connecting power supply. In this embodiment, obtaining the annual maximum load of each connecting line can help determine which lines have overload problems and find the specific problematic lines. Calculating the sum of the annual maximum load of the power supply and the annual maximum load of the connecting line, and calculating the coincidence factor can determine the annual maximum load of the connecting power supply, so as to ensure the normal operation of the power supply system at the maximum load. By calculating the product of the sum of the annual maximum load of the power supply and the annual maximum load of the connecting line and the coincidence factor, the annual maximum load of the connecting power supply can be obtained, which can better evaluate and plan the load situation of the distribution network system and ensure the reliability and stability of the system.

[0050] As Figure 4 shown, for the analysis of the annual maximum load of the connecting power supply of the main line segment of the distribution network line, based on the asset system ledger data analysis of the distribution network line with direct connection, combined with the analysis of the annual maximum load data of the opposite-side distribution network line with direct connection in the dispatching automation system, analyze the annual maximum load of the connecting power supply of the main line segment of the distribution network line.

[0051] Specifically manifested as: 1) Statistical analysis of the annual maximum load data of the opposite-side distribution network line with direct connection, based on the asset system ledger data analysis of all opposite-side distribution network lines with direct connection. At the same time, according to the opposite-side distribution network line information, obtain the annual maximum load of the distribution network line in the dispatching automation system. Let there be n opposite-side distribution network lines with direct connection, and F i be the annual maximum load of the i-th opposite-side distribution network line. The annual maximum load F ZF in the opposite-side distribution network lines with direct connection (i.e., the annual maximum load of the connecting line) is: ; 2) Analysis of the annual maximum load of the connecting power supply of the main line segment of the distribution network line. Based on the annual maximum load F F of the normal operation mode power supply of the main line segment of the distribution network line calculated and analyzed in S2 and the annual maximum load F ZF of the opposite-side distribution network line with direct connection, calculate the annual maximum load of the connecting power supply of the main line segment of the distribution network line, and consider the coincidence factor k. The coincidence factor k is default set to 0.9. The annual maximum load F YX of the connecting power supply of the main line segment of the distribution network line (i.e., the annual maximum load of the connecting power supply) is: .

[0052] According to some exemplary embodiments of the present application, determining whether the main line is overloaded based on the annual maximum load of the contact power supply includes: obtaining the rated current-carrying capacity of the main line; determining that the main line is overloaded when the annual maximum load of the contact power supply is greater than or equal to the rated current-carrying capacity; and determining that the main line is not overloaded when the annual maximum load of the contact power supply is less than the rated current-carrying capacity. In this embodiment, according to the relationship between the annual maximum load of the contact power supply and the rated current-carrying capacity of the main line, it is possible to determine whether the main line is in an overloaded state, timely discover the overloading problem of the main line and take measures to ensure the safe and stable operation of the system.

[0053] Specifically, for the analysis of the overloaded operation of the main line segment of the distribution network line, based on the annual maximum load F of the contact power supply calculated by S3 for the main line segment of the distribution network line YX , at the same time, query the parameters of the main line segment of the distribution network line through the asset system to obtain the rated current-carrying capacity F corresponding to the line segment ED , by analyzing and comparing F YX and F ED numerical values, determine whether the main line segment of the distribution network line is overloaded. When F YX ≥ F ED , it is defined as the main line segment of the distribution network line being overloaded; when F YX < F ED , it is defined as the main line segment of the distribution transformer line not being overloaded.
