[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] The power network diagram generation method based on partition units provided in this application can be applied to Figure 1 In the application environment shown, the power network 102 and the server 104 communicate with each other through the network. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0047] The power network 102 includes a plurality of first partition units and second partition units. When a second partition unit that has not constructed a power network diagram needs to construct a power network diagram, a request will be sent to the server 104. The server 104 responds to the request and obtains the power network diagrams of the plurality of first partition units, and constructs a type set with the network connection types in the power network diagrams of the plurality of first partition units as objects. Then, the power equipment in the second partition unit is obtained, and a power network diagram is constructed for the second partition unit according to its network requirements and the created type set.

[0048] In one embodiment, Figure 2 As shown, a method for generating a power network diagram based on partition units is provided, and the method is applied to Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0049] Step 202, obtaining a power network diagram of at least one first partition unit, wherein the first partition unit is a partition unit for which a power network diagram has been constructed and has no intersection with the second partition unit, and the second partition unit is a partition unit for which a power network diagram is to be constructed.

[0050] Among them, the first partition unit is the partition unit that currently needs to establish a power network diagram, and the introduced second partition unit is the partition unit that has already established a power network diagram. The first partition unit and the second partition unit both have several power devices of the same type or different types in hardware. These power devices send the current working data or monitoring data back to the monitoring platform (i.e., the server). Since the monitoring platform can identify the source of the data, when the power devices in the partition unit are connected to the existing network, the power network diagram can be constructed for the corresponding area of ​​the partition unit in the monitoring platform.

[0051] Specifically, when the second partition unit needs to construct a power network diagram, the server will obtain the power network diagram of the first partition unit as a basis for constructing the power network diagram of the second partition unit.

[0052] Step 204: Analyze the power network diagram of the first partition unit to determine the network connection type based on the power equipment, and construct a type set with the network connection type as the object.

[0053] The type set stores the network connection types of multiple first partition units.

[0054] Specifically, by intelligently analyzing the power network diagram of the first partition unit, the common points between the constructed power network diagrams can be found, and based on these common points, the network connection type of the power equipment can be extracted. For example, the three-phase lines of the transformer are respectively connected to the circuit breaker, which is one of the network connection types. For example, through the above intelligent analysis, the connection methods for different purposes in the partition unit can be obtained.

[0055] In addition, in order to improve the accuracy of the type set, the number of first partition units is often multiple, and the more first partition unit samples there are, the more accurate the type set obtained by analysis is. It is understandable that intelligent analysis can be different analysis methods, such as a wiring diagram analysis system dedicated to the power grid, or a self-built database based on deep learning according to actual needs, etc., which are not listed one by one here.

[0056] Step 206, obtaining the power equipment in the second partition unit, and generating a power network diagram of the second partition unit according to the network layout requirements of the second partition unit and the type set.

[0057] The basis of the network connection type is the power equipment of the partition unit and the network requirements of the partition unit (that is, the grid access function to be achieved).

[0058] Specifically, when the power equipment in the second partition unit is obtained, the power network diagram of the second partition can be automatically generated according to the network layout requirements and type set of the second partition unit.

[0059] In the above-mentioned method for generating a power network diagram based on partition units, the power network diagram of the first partition unit is analyzed by the server to determine the type of network connection based on the power equipment, thereby obtaining a type set for automatically constructing the power network diagram of the partition unit. Since the type set can combine multiple types of connection methods, it has good adaptability to different power equipment in the second partition unit, and can automatically construct a power network diagram based on the power equipment of the current second partition unit, so that the present application does not need to manually connect the power equipment, thereby improving the efficiency of constructing the power network.

[0060] In one embodiment, analyzing the power network diagram of the first partition unit to determine the type of network connection based on the power equipment includes:

[0061] Obtain the device type and connection relationship of the power equipment of the first partition unit; and determine the network connection type of the first partition unit based on the device type and the connection relationship.

[0062] The equipment type refers to the type and model of the power equipment, and the connection relationship reflects how the power equipment is connected. Depending on the different grid access functions to be achieved by the partition unit, the connection relationship of the same type of power equipment in the power network diagram may not be the same.

[0063] Specifically, the common point between the partition units is the power equipment. First, analyze which power equipment is in a first partition unit and what the types of these power equipment are. Then, identify the connection relationship between these power equipment, classify and summarize the connection relationship, and finally summarize the network connection type of the current first partition based on the device type and connection relationship obtained above. By analyzing each first partition unit in the above manner, multiple network connection types can be obtained for constructing a type set.

[0064] In this embodiment, the network connection type of the first partition unit is determined by obtaining the power equipment type and connection relationship of the first partition unit. For the first partition units with more constructed power network diagrams, more network connection types are determined, so that the samples of the constructed type set are richer.

[0065] In one embodiment, determining the network connection type of the first partition unit based on the device type and the connection relationship includes:

[0066] Splitting the power network diagram of the first partition unit according to a preset rule to obtain each minimum connection unit, wherein the minimum connection unit is a unit composed of power equipment and connection relationships that realize any power grid access function;

[0067] The network connection type of the first partition unit is determined according to the connection relationship between the minimum connection units.

[0068] Specifically, according to the wiring diagram of the first partition unit, some common connection relationships can be analyzed and obtained. Taking the realization of a certain function as a unit, the corresponding power equipment and its connection relationship are summarized into the minimum connection unit, and then the power network diagram of the first partition unit is formed by connecting these minimum connection units to each other. Therefore, it can be known that in addition to obtaining the minimum connection unit, the connection relationship between these minimum connection units must be determined, so that the function determined by the minimum connection unit is combined into the total function of the first partition unit, and the network connection type of the first partition unit is summarized.

[0069] In this embodiment, the first partition unit is split according to a preset rule to obtain the minimum connection units, and then the network connection type of the first partition unit can be determined according to the connection relationship between the minimum connection units.

[0070] In one embodiment, generating the power network diagram of the second partition unit according to the network layout requirement of the second partition unit and the type set includes:

[0071] According to the network layout requirements of the minimum connection unit and the second partition unit in the type set, the connection relationships of the power equipment in the second partition unit are obtained; according to the grid access functions realized by the various connection relationships, the first connection relationship whose grid access function conflicts with the power grid environment is deleted; according to the preset principle, the second connection relationship that has not been deleted is displayed, and the second connection relationship is used as an alternative option for the power network diagram of the second partition unit.

[0072] Each connection relationship includes a plurality of first connection relationships and a plurality of second connection relationships.

[0073] Specifically, first obtain the network requirements of the first partition unit, for example, what access function the first partition unit needs to achieve, and then obtain the power equipment of the first partition unit. According to the network requirements and the number and type of power equipment, match the minimum connection unit in the type set. Since there may be multiple connection relationships obtained after matching, it is necessary to delete the connection relationships that cannot achieve the network requirements, and the remaining connection relationships are displayed based on the optimal principle for operation and maintenance personnel to choose. Among them, the optimal principle can be the principle of maximizing functions or the principle of minimizing resource consumption. Operation and maintenance personnel can set it according to actual needs.

[0074] In this embodiment, the function of automatically constructing a power network diagram for a new partition unit based on a historical power network diagram is implemented. Since the type set can combine multiple types of connection methods, it has good adaptability to different power equipment in the first partition unit. It can automatically construct a power network diagram based on the power equipment in the current first partition unit, avoiding manual connection of power equipment and improving the efficiency of building the power network.

[0075] In one embodiment, displaying the undeleted second connection relationship according to a preset principle includes: displaying the undeleted second connection relationship according to a principle of maximizing functions or a principle of minimizing resource consumption.

[0076] Among them, the principle of maximizing functions means that when selecting various connection relationships, the server will give priority to the connection mode that maximizes the functions. The principle of minimizing resource consumption means that when selecting various connection relationships, the server will give priority to the energy consumption generated after the connection of various power devices, the required circuit connection equipment, etc., which are the least consumed. It is feasible to use either the principle of maximizing functions or the principle of minimizing resource consumption as the preset principle, or use them as the preset principles at the same time.

[0077] In this embodiment, the second connection relationship that has not been deleted is displayed according to the principle of maximizing functions or minimizing resource consumption, so that the displayed second connection relationship can achieve maximizing functions or minimizing resource consumption.

[0078] In one embodiment, Figure 3As shown, the method for generating a power network diagram based on partition units includes:

[0079] Step S302: Acquire a power network diagram of at least one first partition unit.

[0080] The first partition unit is a partition unit for which a power network diagram has been constructed and has no intersection with the second partition unit, and the second partition unit is a partition unit for which a power network diagram is to be constructed.

[0081] Step S304: Acquire the device type and connection relationship of the power devices of the first partition unit.

[0082] Step S306, splitting the power network diagram of the first partition unit according to a preset rule to obtain each minimum connection unit.

[0083] Among them, the minimum connection unit is a unit composed of power equipment and its connection relationship that realizes any grid access function.

[0084] Step S308: determining the network connection type of the first partition unit according to the connection relationship between the minimum connection units.

[0085] Step S310, obtaining the power equipment in the second partition unit, and obtaining the connection relationship of the power equipment in the second partition unit according to the minimum connection unit in the type set and the network layout requirements of the second partition unit;

[0086] Step S312, according to the grid access functions realized by each connection relationship, deleting the first connection relationship whose grid access function conflicts with the power grid environment;

[0087] Step S314: displaying the second connection relationship that has not been deleted according to a preset principle, and using the second connection relationship as an alternative item of the power network diagram of the second partition unit.

[0088] In this embodiment, the server analyzes the power network diagram of the first partition unit to determine the network connection type based on the power equipment, thereby obtaining a type set for automatically constructing the power network diagram of the partition unit. Since the type set can combine multiple types of connection methods, it has good adaptability to different power equipment in the second partition unit, and can automatically construct the power network diagram based on the power equipment of the current second partition unit, so that the present application does not need manual connection of power equipment, thereby improving the efficiency of constructing the power network.
