[0061] In an optional embodiment, the number of power supply users of each circuit breaker in the simulated interconnection line can be determined when the pre-selected distribution network line and multiple candidate distribution network lines are in simulated interconnection operation, and the line branch status interconnection result can be obtained. Specifically, the pre-selected distribution network line and the candidate distribution network line can be imported into the simulation model by using the power system simulation software, the simulation parameters can be set and the interconnection operation can be performed. In the simulated interconnection operation, the number of power supply users of each circuit breaker in the simulated line can be calculated and determined according to the load information and the position of the circuit breaker. According to the result of the simulated interconnection operation, the status interconnection result of the line branch can be obtained, including which line branches can supply power, which line branches have faults or power outages, etc. Through the above steps, it is possible to achieve the purpose of determining the number of power supply users of each circuit breaker when the pre-selected distribution network line and multiple candidate distribution network lines are in simulated interconnection operation based on the distribution network line topology structure and the distribution network line ledger data, and obtaining the line branch status interconnection result, which can help power system operators to effectively analyze and optimize the distribution network line interconnection and improve the reliability and stability of the power grid.

[0062] The technical solution proposed in this application is explained below in combination with an optional application scenario. As the end of the power system, the distribution network is directly connected to the power users and is responsible for providing reliable power supply to the power users. With the improvement of people's living standards, higher requirements are also placed on the quality of power supply, which brings challenges to the construction of a highly reliable grid structure of the distribution network. At the same time, with the construction of a new power system with new energy as the main body, more and more emerging energy, charging stations, energy storage and other equipment are connected to the distribution network. In order to ensure a high proportion of new energy consumption, more stringent requirements are placed on the grid structure of the distribution network. Based on the above analysis, in order to meet people's needs for high-reliability power supply quality and high-proportion consumption of new energy, it is necessary to transform the weak distribution network grid structure. For example, a single radial line improves the power supply reliability by establishing connections with other lines, and weak links in the grid such as large branches and heavy overloads need to re-establish a connection structure with other lines.

[0063] At present, the improvement of the distribution network line connection structure mainly relies on manual work. At the same time, since the distribution network line single-line diagram lacks the real-time location information of the equipment, manual work is required to further formulate the construction method of the distribution network line connection structure through on-site survey combined with systems such as equipment center and geographic information system. At present, this method has the problems of large workload and low efficiency, and there is insufficient data support, which leads to unreasonable results of the distribution network line connection construction analysis.

[0064] Based on the above problems, the main technical problems to be solved in this aspect mainly include the following aspects: based on the topological structure and geographic location information of the distribution network line, intelligent decision-making analysis of the location of the access point of the distribution network line connection structure is realized, replacing the large-scale data analysis of the location of the traditional manual connection access point; based on the distribution network line structure and operation data information, intelligent analysis of whether the newly built distribution network line connection will cause heavy overload, same-mother and same-station connection, head-end connection, etc. is realized, so as to achieve a reasonable layout of the newly built distribution network line connection; based on the geographic location information of the distribution network equipment, combined with the map system, the intelligent display of the newly constructed connection status of the distribution network line is realized, providing visual data support for the construction of distribution network line connection.

[0065] The present application proposes an intelligent decision-making analysis method for building a distribution network line connection, and its specific implementation process may include the following: data processing and analysis of distribution network line topology, operation data, geographic location information, etc., obtaining distribution network line ledgers and topology data based on the equipment center system, and obtaining distribution network line current data through the dispatching automation system, and obtaining the geographic location information of distribution network line equipment through the geographic information system (GIS), and performing correlation analysis on the data between each system.

[0066] Specifically, the distribution network line ledger and topological structure data acquisition can be based on the equipment center system to obtain the distribution network line model, and by parsing the distribution network line model, the distribution network line ledger and topological structure data information can be obtained; the distribution network line load data acquisition can be based on the distribution network line historical current data collected by the dispatching automation system to calculate the highest current of the distribution network line in the year; the distribution network line equipment geographic location information acquisition can be based on the geographic information system in the distribution network line ledger data to obtain the longitude and latitude data of the distribution network line equipment, so as to achieve the acquisition of the distribution network line equipment geographic location information.

[0067] It is possible to conduct intelligent analysis of the location of access points for the connection construction of distribution network lines. Based on the topological structure data of the distribution network lines, the analysis starts from the equipment at the end of the distribution network line public equipment that can establish the contact point and gradually moves towards the front end of the line. It is analyzed whether there are other adjacent lines within the specified range of the equipment where the contact point can be established, and other adjacent distribution network line access points within the specified range are used as access points for the connection construction of the distribution network lines.

[0068] Specifically, data analysis of public equipment on distribution network lines can be carried out. Based on the inventory data of distribution network line equipment analyzed by the distribution network model, it can be considered that only public equipment on distribution network lines can be used as distribution network line connection establishment points, and distribution network line dedicated equipment cannot be used as distribution network line connection establishment points; data analysis of the location of preliminary access points for connection of public equipment on distribution network lines can be carried out. Based on the data of common equipment of distribution network lines, the data of power room in cable lines and pole tower of overhead lines are analyzed and used as the data of preliminary access point for the construction of common equipment of distribution network lines; the situation of other lines adjacent to the preliminary access point for the construction of common equipment of distribution network lines can be analyzed. Among all the preliminary access point locations of common equipment of distribution network lines, starting from the end of distribution network lines, the preliminary access point is analyzed according to the geographical location information of the distribution network common equipment ledger to determine whether there are other adjacent distribution network lines that can be connected within the specified diameter range of K, for example, 500 meters can be used as the default. The access point for the connection of the other distribution network line must also be the power room in the cable line of common equipment of distribution network and the pole tower of overhead line. At the same time, if there are multiple adjacent distribution network lines that can be connected within the specified diameter range of K, all adjacent distribution network lines are included as access points that can be connected, and subsequent preferential analysis is performed.

[0069] The feasibility analysis of the distribution network line connection construction plan can be carried out. Based on the analyzed distribution network line connection construction access point and the data information of the adjacent distribution network line on the opposite side, the heavy overload after the connection construction, the connection with the same 10kV bus and the same substation, and the large branch situation can be used to analyze whether the constructed connection point is feasible.

[0070] Specifically, a heavy overload analysis of the distribution network line connection construction can be performed. Based on the operating load data of the distribution network line on this side and the opposite distribution network line constructed by the connection, it can be analyzed whether the constructed connection will cause a heavy overload on the opposite distribution network line during the load transfer process during the actual operation process. The allowable current carrying capacity of the distribution network line on this side that needs to be connected can be determined. The annual maximum load of the distribution network line on this side is F1 amperes, which can be the maximum load of the first year mentioned above; the allowable current carrying capacity of the adjacent opposite distribution network line to establish the connection is F2 amperes, which can be the rated current carrying capacity of the candidate line mentioned above; the annual maximum load of the adjacent opposite distribution network line is L2 amperes, which can be the maximum load of the second year mentioned above; the load simultaneity rate is t, and after the load of the distribution network line on this side that needs to be connected is transferred to the adjacent opposite distribution network line, the annual maximum load rate of the adjacent opposite distribution network line is f, which can be the above-mentioned line operation heavy overload connection result, which can be expressed as:

[0071]

[0072] If the annual maximum load rate f of the adjacent opposite distribution network lines is greater than or equal to 80%, it means that the constructed connection will cause heavy overload of the adjacent opposite lines during the load transfer process, and the connection construction plan is not the optimal plan; if the annual maximum load rate f of the adjacent opposite distribution network lines is less than 80%, it means that the connection construction plan is a preliminary optional plan.

[0073] The distribution network line connection construction with the same 10kV bus and the same substation connection analysis can be carried out, that is, the connection result of the line bus and the substation can be determined. Based on the distribution network line ledger data, the 10kV bus and the substation to which the distribution network line on this side that needs to be connected belong can be analyzed, as well as the 10kV bus and the substation to which the distribution network line on the adjacent opposite side that is connected can be analyzed; if the distribution network line on this side that needs to be connected and the distribution network line on the adjacent opposite side that is connected belong to the same 10kV bus or are powered by the same substation, it means that the connection construction plan is not the optimal plan; if the distribution network line on this side that needs to be connected and the distribution network line on the adjacent opposite side that is connected do not belong to the same 10kV bus and are not powered by the same substation, it means that the connection construction plan is a preliminary optional plan, and the specifications of the above-mentioned line bus can be determined according to actual needs and are not limited here.

[0074] A large branch analysis of the distribution network line can be performed, that is, the connection result of the line branch status can be determined. Data can be parsed based on the distribution network line model to count the circuit breaker switches that do not have a connection point in the later section of the distribution network line after the distribution network line that needs to be connected is connected according to the plan. The distribution transformers powered by each circuit breaker switch are counted separately, and the user number of each distribution transformer is analyzed. If there are multiple distribution transformers with the same user number, they are defaulted to a unified user. The number of users powered by the circuit breaker in each later section that does not have a connection point is counted based on the user number. If the number of users powered by the circuit breaker switch that does not have a connection point in the later section is greater than the judgment threshold, for example, 10 households, it is defaulted to be a distribution network line that needs to be connected. The connection construction has a large branch, which means that the connection construction is not the optimal solution; if the number of users powered by the circuit breaker switch that does not have a contact point in the later section is greater than 10 households, it means that the connection construction plan is a preliminary optional plan. The judgment threshold of the number of users powered by the above-mentioned circuit breaker switch can also be determined according to actual needs and is not limited here.

[0075] It can conduct intelligent analysis on the optimal solution for the connection of distribution network lines. It can start from the access point at the very end of the distribution network line that can be connected, conduct feasibility analysis on the connection of distribution network lines, and analyze the access point and adjacent distribution network line content of the optimal solution for the connection of distribution network lines.

[0076] Specifically, during the feasibility analysis of the distribution network line connection construction, the access point at the end of the distribution network line that can be connected can be used. If there is no heavy overload, connection with the same 10kV bus and the same substation, large branches, etc. after the distribution network line connection is constructed, the network construction plan at the end of the distribution network line is the optimal plan, and the connection construction plan analysis work is completed.

[0077] If during the feasibility analysis of the distribution network line connection construction of the access point that can be connected at the end of the distribution network line, if there is heavy overload, connection with the same 10kV bus and the same substation, large branches, etc. after the distribution network line connection is constructed, the network construction plan at the end of the distribution network line is not the optimal plan, and it is necessary to continue to analyze the access points that can be connected from the end of the distribution network line forward.

[0078] During the feasibility analysis of the distribution network line connection construction from the access point at the end of the distribution network line to the front end of the line, if there is no heavy overload, connection with the same 10kV bus and the same substation, large branches, etc. after the distribution network line connection is constructed, the network construction plan analyzed only to this access point is the optimal plan, and the connection construction plan analysis work is completed.

[0079] During the feasibility analysis of the distribution network line connection construction from the last contactable access point to the front end of the line, if all the contact access points of the distribution network line are heavily overloaded, connected with the same 10kV bus and the same substation, and have large branches, then the last contactable access point in the distribution network line and the corresponding adjacent opposite line are the optimal solutions.

[0080] It is possible to display multi-dimensional data on the map of the distribution network line connection construction plan. Based on the distribution network line topology structure and the location information such as the longitude and latitude of the power supply equipment, combined with the analysis results of the distribution network line connection construction plan, it is possible to display multi-dimensional data on the map of the distribution network line topology structure and equipment, connection construction plan and other data information by calling the map.

[0081] The distribution network line topology and equipment map can be displayed in real time. Based on the geographical location information and topology of the distribution network line, the distribution network line topology and power supply equipment data can be displayed on the map by calling the real-time map information. The distribution network line topology and equipment map can be displayed in real time through the map.

[0082] It can intelligently sort and display the distribution network line connection construction schemes. It can realize intelligent sorting of distribution network line connection construction schemes based on the schemes analyzed by the distribution network line connection construction methods, and based on whether the connection construction schemes will cause heavy overload, mother 10kV bus or substation power supply, and large branches. It can also display the access points of the distribution network lines that need to be connected on this side of each scheme and the access points of the adjacent distribution network lines on the opposite side.

[0083] The map of the distribution network line connection construction plan can be displayed intuitively. According to the location information such as the longitude and latitude of the lines that need to be connected on this side and the access points of the adjacent distribution network lines on the opposite side of each connection construction plan, combined with the line power supply path relationship in the connection construction plan, the distribution network lines that need to be connected on this side, the adjacent distribution network lines on the opposite side and the newly constructed connection lines can be marked with different colors to realize the intuitive display of the distribution network line connection construction plan map.

[0084] It can realize intelligent decision-making analysis of the location of the access point of the distribution network line connection structure, and can realize intelligent analysis of whether the newly built distribution network line connection will cause heavy overload, same-mother and same-station connection, head-end connection, etc.; it can realize intelligent display of the newly constructed connection status of the distribution network line.
