[0002] In the process of power distribution network dispatching, in the prior art, dispatchers usually analyze the power grid connection status based on the single-line connection diagram of the 10kV line and make decisions. When an accident or abnormality occurs in the power grid, the dispatcher needs to quickly and accurately grasp the real-time status of the power grid in order to formulate an effective response strategy.

[0003] However, the single-line connection diagram can only display the basic grid structure and connection relationship of a single line, and it cannot fully display the topological structure of the grid. For example, it cannot intuitively reflect the topological structure of the opposite line that has a connection relationship with the line. Especially when faced with multiple connection lines and complex grid structures, the single-line diagram cannot provide the complex connection relationship between multiple connection lines and complex grid structures, resulting in the dispatcher having to repeatedly refer to multiple different systems to compare and associate the connection relationship, which will not only lead to low efficiency and slow dispatch response speed, but also increase the risk of decision-making errors, making it difficult to meet the current needs for grid dispatch and power supply reliability.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0022] For ease of understanding, the relevant technical background of the present invention is first introduced by way of example.

[0023] The dispatching of distribution network is to comprehensively consider the physical characteristics of the power grid, load demand, power generation capacity, network loss, safety and economic operation and other factors, monitor and control the power grid in real time, and take prompt measures to deal with power grid accidents. Therefore, in order to achieve safe dispatching of distribution network, it is necessary to analyze the connection status of the power grid in real time. The line connection diagram is a power system diagram used to show the connection relationship between various power equipment and lines in the power system. The traditional distribution network dispatching method is that the dispatcher obtains the power grid connection status based on the line connection diagram, and then makes corresponding control decisions. Therefore, the line connection diagram is the key to achieve safe dispatching of distribution network. However, the line connection diagram in the prior art is for a single line, that is, a single line diagram. This type of single line diagram is only for a specific line, and therefore only contains the connection relationship of the equipment on the specific line. For example, for a 10kV line, the dispatcher makes control decisions based on the single line connection diagram of the 10kV line. For a distribution network with a complex structure, it may contain multiple connection lines, that is, there are multiple lines connecting the same or different substations or nodes, so there will be a connection relationship between the equipment on different lines. The single-line diagram can only provide the grid structure and contact relationship of the current line, and cannot intuitively reflect the topological structure of the opposite line that has a contact relationship with the line. The opposite line is the power line that starts from the current substation or node and connects to another substation or node. Therefore, when a dispatch decision is required, the dispatcher needs to manually compare and associate the contact relationships of multiple contact diagrams for different lines to determine the contact relationship between the current line and other lines. The manual comparison and association method is not only inefficient, but also prone to errors, which will lead to problems such as slow dispatch response and wrong decisions.

[0024] The present invention obtains the equipment and topological relationship data of the designated feeder, searches for the equipment belonging to different feeders, and performs topological tracking to generate the contact relationship between the equipment of different feeders, so as to form a regional contact relationship set, and then generates the required topological description file according to the regional contact relationship set, and then generates the contact relationship between the feeders in layers according to the equipment type based on the topological description file, so as to obtain regional line contact relationship sets of different levels, and finally generates the final regional line contact map according to the equipment to be displayed, and can automatically generate a complete set of regional line contact maps for the designated feeder, so as to improve the speed and accuracy of generating the regional line contact map, which can not only reflect the power grid structure and contact relationship of the designated line, but also can intuitively reflect the topological structure of the opposite line that has a contact relationship with the designated line, and can also obtain line contact maps of different levels by adopting a layered manner, and can also reduce the complexity of the contact relationship of each layer by using the layered manner, so as to improve the response speed and accuracy of the distribution network dispatching.

[0025] like Figure 1 As shown, the steps of the method for generating a distribution network area line connection diagram in this embodiment include: Step S01. Obtain all equipment information of feeders of a specified voltage level in the distribution network, topological relationship data between equipment, and real-time status information of each switch.

[0026] For the target feeder in the distribution network that needs to generate the regional line connection diagram, such as a 10kV large feeder, the information of equipment such as transformers, circuit breakers, switches, and the topological relationship data between the equipment can be obtained from the power grid resource library. Equipment information can include equipment ID number and equipment attributes , then the device information can be expressed as , where the device ID is the identifier corresponding to each device, and the device attributes Can include real-time on / off status of the device ,type ,capacity ,Location , whether it contains important users The information of .

[0027] It is understandable that in addition to the device ID number and device attributes, device information may also use other types of device-related information, such as device model, etc. according to actual needs. Device attributes may also use other types of attribute information besides the above attributes, such as power, power consumption, etc.

[0028] Optionally, the topological relationship data between devices can be represented based on graph theory, and an edge E can be used to connect two devices to represent the electrical connection between the two devices. Indicates the device With equipment The connection between them, and then combined with the device information and topological relationship, the information set of the target feeder can be obtained as follows: ,in n Indicates the number of devices. m Indicates the number of edges.

[0029] Optionally, the switch status values ​​of each device can be read from the distribution automation system, and the update function can be used to trigger the timed update. Triggering the use of preset automatic data update functions Update the real-time status of each switch , get the real-time status information of the switch, that is, , so that the real-time status of the switch can be automatically updated according to the changes in topological connection data, ensuring the real-time and accuracy of the generated connection diagram.

[0030] Step S02: Find out the devices belonging to different feeders according to the topological relationship data between the devices, perform topological tracking on the devices belonging to different feeders to generate the contact relationship between the devices of different feeders, and construct a regional contact relationship set.

[0031] There may be multiple feeders of a specified voltage level, and the devices with connection relationships may belong to different feeders. For example, for a 10kV large feeder, there may be multiple 10kV feeders, and there may be devices with connection relationships between different feeders. Based on the topological relationship data between the devices, the devices belonging to different feeders can be found, and then the topological tracking of the devices of different feeders can be performed separately to generate the connection relationship between the devices of different feeders, forming a regional connection relationship set. The regional connection relationship set contains the connection relationship between the devices of different lines. Topological tracking is to identify the electrical connection relationship between the feeder and its connected devices, and obtain the connection relationship between the devices of different feeders by using topological tracking, so that the topological structure of the opposite line that has a connection relationship with the current line can be quickly obtained, and a more complete topological structure of the power grid can be obtained.

[0032] Optionally, based on the acquired topological relationship data between devices, all edge E relationships in the topological relationship data can be traversed. With equipment When they belong to different 10kV feeders, it is determined that the two devices have a contact relationship between feeders, and the two devices are topologically tracked using a breadth-first search algorithm such as BFS to generate a contact relationship between 10kV large feeders and form a regional contact relationship set.

[0033] Preferably, the important users that need to be paid attention to can also be marked so that the information of the important users can be displayed in the generated regional line connection map. For example, the user number of the important user is obtained, the transformer station corresponding to the user is found, and the station is marked as "important user". , and the display settings can be made based on this tag.

[0034] Preferably, it is also possible to search for dual power users, and search for the corresponding devices on both sides of the dual power users, and add the contact relationship between the found devices and the dual power users to the regional contact relationship set. The dual power user is a single user associated with two independent user numbers. A table of user number and distribution transformer correspondence will be stored in the distribution automation system or data center. Based on the table, the belonging relationship and topological association relationship of the feeder can be obtained accordingly. If a single user is associated with two independent user numbers, the user is determined to be a dual power user, and the dual power user can be automatically identified. By automatically identifying the dual power user, the contact relationship of the dual power user is added to the distribution network area contact map, so that the relevant information of the dual power user can be easily obtained in the subsequently generated regional line contact map, so that it is convenient to use the information to formulate relevant transfer strategies and improve the power supply reliability of the power grid to important users. Assume that the set of dual power users found is expressed as , for each dual power user, apply the mapping function Find the devices corresponding to both sides of the user , , which can be expressed as , then the device , The liaison relationship with dual power users is added to the regional liaison relationship set.

[0035] Step S03: Generate a topology description file of the regional contact map according to the device information in the regional contact relationship set and the contact relationship between the devices.

[0036] The topology description file is used to record and describe in detail the physical structure and connection relationship of the regional communication diagram to be generated. The topology description file specifically contains information about each device (transformer, circuit breaker, switch, etc.), topological relationship data between devices, real-time status information of each switch, and the communication relationship between devices between different feeders. The topology description file can be used to fully characterize the status of the equipment in the target feeder and the communication relationship between devices between different feeders.

[0037] Step S04. Layer the equipment according to the topology description file of the regional communication diagram, and perform topological tracking on each device in each layer to generate the communication relationship between the equipment between the feeders, and obtain a set of regional line communication relationships at different levels, where each layer includes multiple categories of equipment, and the next layer includes the information of the equipment in the previous layer and the added equipment of the specified category.

[0038] The importance of different users in the regional line connection diagram is different, and the distribution network pays different attention to different equipment and different users during the dispatching process. If all devices are directly displayed in the same layer, it will be difficult to quickly obtain the information of the required equipment due to the large amount of equipment and data. This embodiment adopts a layered display method, by layering all devices according to the device type, each layer displays the information of the specified type of equipment and the contact relationship between feeders, where the lower layer only displays the information of some equipment types, and the upper layer adds the specified type of equipment on the basis of the lower layer, forming a layer-by-layer detailed display method, so that the line contact relationship of different levels can be intuitively and quickly obtained. The layered display method can not only conveniently pay attention to the equipment information of a specific level, but also effectively reduce the complexity of the contact relationship because the lower layer only contains some types of equipment information, thereby improving the readability of the regional contact diagram under different dispatching operation mode adjustments and the efficiency of the dispatcher in formulating the transfer strategy.

[0039] For example, the equipment on the contact diagram is divided into four layers according to the equipment type, wherein the equipment on the first layer includes the outgoing circuit breaker and the contact switch, the equipment on the second layer includes the equipment on the first layer and the self-distribution switch, and the designated user, wherein the designated user can be a designated important user, a designated user to be monitored, etc., and the designated user can be a single power user or a dual power user; the equipment on the third layer includes the equipment on the second layer and the non-self-distribution switch, and the equipment on the fourth layer includes the equipment on the third layer and the dual power user, and the dual power user is a single user associated with two independent user numbers. Taking the designated user as an important user as an example, the generated regional line contact diagram includes four levels, the first level corresponds to: outgoing circuit breaker, contact switch; the second level corresponds to: outgoing circuit breaker, contact switch, self-distribution switch, important user; the third level corresponds to: outgoing circuit breaker, contact switch, self-distribution switch, non-self-distribution switch, important user; the fourth level corresponds to: outgoing circuit breaker, contact switch, self-distribution switch, non-self-distribution switch, important user, dual power user.

[0040] It can be understood that the specific number of layers and the type of equipment divided in each layer can be configured according to actual needs. According to different needs, the equipment that needs attention can be divided into a specific layer, and the equipment that needs special attention can be divided into a lower layer so that it can be displayed in the form of a simple diagram.

[0041] As an optional implementation, the devices are layered according to the topology description file of the regional connection diagram, and the topology of each device in each layer is tracked to generate the connection relationship between the devices between the feeders. The specific steps of obtaining the regional line connection diagram include: Step S401. Obtain the first-layer device information according to the topology description file of the regional contact map, and perform topology tracking on each device of the first layer to regenerate the contact relationship between the devices of the feeder lines to form a first-layer regional contact relationship set; Step S402. Add the specified category of equipment types to the upper layer of equipment to form the second layer of equipment, and perform topological tracking on each of the second layer of equipment to regenerate the contact relationship between the feeders to form a next layer of regional contact relationship set; Step S403: Repeat steps S401 and S402 until all layer region contact relationship sets are obtained.

[0042] For example, the devices on the contact diagram are divided into four layers according to device type. The first-layer device model set in which the device type is the outgoing circuit breaker and the tie switch is marked as a hierarchical display, uses the breadth-first search algorithm BFS for topology tracking, regenerates the connection relationship between the 10kV large feeders, and forms the first-layer regional connection relationship set; based on the first-layer device model set, add The equipment type is the switch as the second-layer equipment model set. The breadth-first search algorithm BFS is used for topology tracking to regenerate the connection relationship between the 10kV large feeders to form the second-layer regional connection relationship set. On the basis of the second-layer equipment model set, add The equipment type is non-distributed switch as the third-layer equipment model set. The breadth-first search algorithm BFS is used for topology tracking, and the connection relationship between the 10kV large feeders is regenerated to form a third-layer regional connection relationship set; on the basis of the third-layer equipment model set, dual power users are added as the fourth-layer equipment model set, and the breadth-first search algorithm BFS is used for topology tracking to regenerate the connection relationship between the 10kV large feeders to form a fourth-layer regional connection relationship set.

[0043] It is understandable that topology tracking may also adopt other tracking algorithms besides the breadth-first search algorithm BFS, such as a boundary tracking algorithm, a vector topology tracking matching algorithm, and the like.

[0044] Step S05. Find the devices to be displayed and the device sets on the corresponding power supply paths from the regional line connection relationship sets at each level, and generate a final regional line connection diagram.

[0045] For each level of regional line connection relationship set, the required equipment can be screened for display, so that the required equipment information can be displayed in layers, and finally the required regional line connection diagram is formed. The regional line connection diagram contains multiple layers, and each layer displays the required equipment information and the connection relationship between feeders.

[0046] By further simplifying each level, the complex connection relationship can be further reduced, and the information of the devices that need to be paid attention to can be clearly displayed. As an optional implementation, the steps of searching for the devices to be displayed from the regional line connection relationship set of each level and generating the final regional line connection map include: Step S501. Find the devices required to be displayed at each layer in the regional line contact diagram, and find the device set on the power path of the required display device through the topology; Step S502: merge the devices that do not need to be displayed on the power path, and generate virtual line devices for connection according to the coordinates of the merged devices, that is, merge the devices that do not need to be displayed and the line segments between the devices into equivalent connecting lines to indicate the connected relationship; Step S503: Render the devices to be displayed and the newly generated virtual line devices to generate the final regional line connection diagrams of different levels.

[0047] The devices required to be displayed at the above-mentioned layers may be important users, dual-power users, or other users that require attention, and may be configured according to actual needs.

[0048] Optionally, you can also use graphic automatic layout algorithms and components to optimize the layout. For example, based on the principles of placing outlet switches on the left and right sides, horizontal and vertical lines, and avoiding crossing lines as much as possible, you can generate simplified regional communication diagrams at different levels. Finally, use graphic display and interactive components to display the generated regional communication diagram, so that you can achieve layered display control of the simplified regional communication diagram.

[0049] The present invention automatically generates a regional line connection diagram based on the connection switches and connection relationships between the distribution network feeders, and displays them in layers according to the equipment types, which can intuitively display the topological structure and equipment status of different levels of power grids. Based on the regional line connection diagram, the dispatcher can quickly grasp the real-time status and topological structure of the current line and the opposite line that has a connection relationship with the current line, thereby significantly improving the speed and efficiency of decision-making. In addition, when dealing with power grid accidents or abnormal situations, it can also adapt to the ever-changing power grid environment and user needs, and has good flexibility and scalability.

[0050] In a specific application embodiment, the effect of the four-level regional line connection diagram generated by the above method of the present invention according to the connection switch and connection relationship between the 10 kV large feeder lines of a distribution network is as follows: Figure 2~Figure 5 As shown, Figure 2~Figure 5 The corresponding topological structure diagrams are part of the first, second, third and fourth levels. Different colors in each diagram represent different feeders. The rectangular symbols in the diagram represent switches, double dots represent dual-power users, and dotted boxes represent users belonging to the same switch station or ring main unit. Important users may be single-power users or dual-power users. Figure 2 , Figure 3 The dual power users are designated as important dual power users. Figure 2~Figure 5 It can be seen that the connection diagram generated by the present invention can reflect the connection relationship between different feeders, and adopts a layered approach to display information of different types of equipment layer by layer, thereby simplifying complex topological relationships.
