Abstract

After all circuit breaker information and all electric meter information in a transformer area are recorded by a master station, command information for generating characteristic current is sent to each electric meter in an electric meter information list in a transparent transmission mode according to a predetermined time interval, and the transparent transmission information is sent to the circuit breaker by a concentrator to query characteristic current information of all electric meters recorded by each circuit breaker and record time corresponding to each characteristic current information. The master station processes one-to-one superior-inferior relationships between each circuit breaker and the electric meter and between the circuit breaker and the circuit breaker based on time sequence relationships formed by the record time of all the queried characteristic current information, and generates a topology relationship graph according to all the processed superior-inferior relationships, so that the topology relationship conditions of all nodes in the transformer area are accurately generated, and operation and maintenance personnel can conveniently and timely troubleshoot problems.

Description

Technical Field

[0001] This invention relates to the field of power management, and in particular to a method, medium, device and system for generating transformer area topology relationships. Background Technology

[0002] The generation of transformer substation topology is of great significance for power management. Traditional methods for generating transformer substation topology mainly involve generating characteristic current information that follows a certain pattern between the neutral and live wires of a line through resistor switching. Then, circuit breakers and concentrators are used to sample and analyze the current information on the line and record the time stamp of signal identification to obtain the topology within the transformer substation.

[0003] However, existing methods for generating transformer area topology relationships are insufficient to accurately generate the topology relationships of all nodes (i.e., concentrators, circuit breakers, or meters) within a transformer area, making it impossible to confirm whether the topology functions are normal and providing data support for maintenance personnel to troubleshoot problems in a timely manner. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a method for generating the topology relationship of a transformer substation, which is in contrast to the above-mentioned prior art.

[0005] The second technical problem to be solved by the present invention is to provide a medium for implementing the above-mentioned method for generating the topology relationship of the transformer area, in contrast to the prior art.

[0006] The third technical problem to be solved by the present invention is to provide an electronic device for implementing the above-mentioned method for generating the topology relationship of the transformer area, in contrast to the prior art.

[0007] The fourth technical problem to be solved by the present invention is to provide a system for implementing the above-mentioned method for generating the topology relationship of the transformer area, in contrast to the prior art.

[0008] The technical solution adopted by this invention to solve the first technical problem is: a method for generating transformer area topology relationships, characterized by comprising the following steps:

[0009] Step 1: The main station records all circuit breaker information and all meter information within the distribution area, forming a circuit breaker information list and a meter information list; the circuit breaker information list contains all circuit breaker information, and the meter information list contains all meter information.

[0010] Step 2: The master station will send the command information for generating the characteristic current to each meter in the meter information list in a transparent manner at predetermined time intervals.

[0011] Step 3: After the master station sends the command information for generating characteristic current to all the meters in the meter information list, the master station sends transparent information to the circuit breaker through the concentrator to query the characteristic current information of all the meters recorded by each circuit breaker and the recording time of each characteristic current information.

[0012] Step 4: The main station processes the time sequence relationship formed by the recording time of all the queried characteristic current information to obtain the one-to-one hierarchical relationship between each circuit breaker and the meter, as well as between circuit breakers.

[0013] Step 5: The main station generates a topology diagram based on all the superior-subordinate relationships obtained from the processing.

[0014] Furthermore, in the method for generating the transformer substation topology, the processing of the one-to-one hierarchical relationship between each circuit breaker and meter, as well as between circuit breakers, is as follows: Steps 41-46:

[0015] Step 41: Obtain the node time information of the response information of all nodes connected to each circuit breaker to form a set of node time information for all circuit breakers; wherein, the node includes child nodes and grandchild nodes, and the node is a circuit breaker or a meter.

[0016] Step 42: Extract all the parent-child relationships from the node time information set, and list all the parent nodes and all the child nodes respectively. Form a list of parent nodes with all the parent nodes and a list of child nodes with all the child nodes.

[0017] Step 43: Iterate through each node in the parent node list to determine whether it has a parent node.

[0018] Step 44: Process the data based on the result of the determination of whether a parent node exists.

[0019] If a node does not have a parent node, the node is taken as an ancestor node and removed from the list of parent nodes, then proceed to step 45; otherwise, proceed to step 43 and continue to traverse and judge the next node until all nodes have been traversed, then proceed to step 46.

[0020] Step 45: Use the list of parent nodes after the removal process as the new list of parent nodes, and proceed to step 43.

[0021] Step 46: Based on all the nodes that have been removed, obtain a list of parent-child node relationships corresponding to all of these nodes.

[0022] In an improved version of the invention, the method for generating transformer area topology relationships further includes: after the master station sends the command information for generating characteristic current to all meters, it determines whether any meters have been missed; if any meters have been missed, the master station sends the command information for generating characteristic current to the missed meter separately again.

[0023] Furthermore, in the method for generating the topology relationship of the transformer area, when the master station determines that any meter in the meter information list does not appear in the topology relationship diagram, the master station determines that any meter is a missing meter.

[0024] In a further improvement, the method for generating the transformer area topology relationship in this invention further includes: displaying the current information corresponding to the node to be queried based on the node information to be queried and the topology relationship diagram.

[0025] To ensure that the recording time sequence of characteristic currents in the circuit breakers is not incorrect, the method for generating the transformer area topology relationship is further improved by having the master station broadcast time synchronization to all circuit breakers within the transformer area.

[0026] The technical solution adopted by the present invention to solve the second technical problem is: a readable storage medium storing a computer program thereon, characterized in that, when the computer program is executed by a processor, it implements the method for generating the topology relationship of the transformer area as described in any one of the claims.

[0027] The technical solution adopted by the present invention to solve the third technical problem is: an electronic device, characterized in that it includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, it implements the method for generating the topology relationship of the transformer area as described in any one of the claims.

[0028] Furthermore, in this invention, the electronic device is the master station.

[0029] The technical solution adopted by this invention to solve the fourth technical problem is: a topology relationship generation system for characteristic currents of electricity meters, which realizes the aforementioned method for generating topology relationships of transformer substations, characterized in that it includes:

[0030] Main site;

[0031] The concentrator connects to the main station;

[0032] At least one circuit breaker, connected to a concentrator; and,

[0033] Multiple electricity meters are connected to their respective circuit breakers.

[0034] Compared with the prior art, the advantages of the present invention are as follows: The method for generating the transformer area topology relationship in this invention involves the main station recording all circuit breaker information and all meter information within the transformer area, and then sending the command information for generating characteristic current to each meter in the meter information list in a transparent manner at predetermined time intervals. The concentrator then sends the transparent information to the circuit breaker to query the characteristic current information of all meters recorded by each circuit breaker and the recording time of each corresponding characteristic current information. The main station then processes the time sequence relationship formed by the recording time of all the queried characteristic current information to obtain the one-to-one hierarchical relationship between each circuit breaker and meter, as well as between circuit breakers. The main station then generates a topology relationship diagram based on all the processed hierarchical relationships, thereby accurately generating the topology relationship of all nodes within the transformer area, which facilitates maintenance personnel to troubleshoot problems in a timely manner.

[0036] Figure 2 This is a schematic diagram of the topology relationship generation system for the characteristic current of the electricity meter in an embodiment of the present invention. Detailed Implementation

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] This embodiment provides a method for generating transformer area topology relationships. Specifically, see [link to documentation]. Figure 1 As shown, the method for generating transformer area topology relationships in this embodiment includes the following steps:

[0039] Step 1: The main station records all circuit breaker information and all meter information within the distribution area, forming a circuit breaker information list and a meter information list. The circuit breaker information list contains information on all circuit breakers, and the meter information list contains information on all meters. For example, for each circuit breaker, the circuit breaker information here can be the identifier for each circuit breaker; similarly, for each meter, the meter information here can be the identifier for each meter.

[0040] Step 2: The master station will send the command information for generating the characteristic current to each meter in the meter information list in a transparent manner at predetermined time intervals.

[0041] In other words, based on the list of electricity meter information formed in step 1, the main station sends command information to generate characteristic current to each electricity meter in the list at predetermined time intervals and in a sequential manner, until the command information to generate characteristic current has been sent to each electricity meter in the list.

[0042] Step 3: After the master station sends the command information for generating characteristic current to all meters in the meter information list, the master station sends transparent information to the circuit breaker through the concentrator to query the characteristic current information of all meters recorded by each circuit breaker and the recording time of each characteristic current information; in this process, the master station will pre-broadcast and synchronize the time of all circuit breakers in the distribution area to ensure that the recording time sequence of characteristic current in the circuit breaker is not incorrect.

[0043] In other words, after the master station sends the command information for generating the characteristic current to all the meters in the meter information list, the circuit breaker will record the response information (including the characteristic current information) to the command information. The circuit breaker will record the response time of the characteristic current information fed back by the meter, and then record this response time to form the recording time for the characteristic current information.

[0044] Step 4: The main station processes the time sequence relationship formed by the recording time of all the queried characteristic current information to obtain the one-to-one hierarchical relationship between each circuit breaker and the meter, as well as between circuit breakers.

[0045] Specifically, in this embodiment, the processing of the one-to-one hierarchical relationship between each circuit breaker and the meter, as well as between circuit breakers, is as follows: Steps 41-46:

[0046] Step 41: Obtain the node time information of the response information of all nodes connected to each circuit breaker to form a set of node time information for all circuit breakers; wherein, the node includes child nodes and grandchild nodes, and the node is a circuit breaker or a meter.

[0047] Step 42: Extract all the parent-child relationships from the node time information set, and list all the parent nodes and all the child nodes respectively. Form a list of parent nodes with all the parent nodes and a list of child nodes with all the child nodes.

[0048] Step 43: Iterate through each node in the parent node list to determine whether it has a parent node.

[0049] Step 44: Process the data based on the result of the determination of whether a parent node exists.

[0050] If a node does not have a parent node, the node is taken as an ancestor node and removed from the list of parent nodes, then proceed to step 45; otherwise, proceed to step 43, continue to traverse and judge the next node in the list of parent nodes, until all nodes have been traversed, then proceed to step 46.

[0051] Step 45: Use the list of parent nodes after the removal process as the new list of parent nodes, and proceed to step 43.

[0052] Step 46: Based on all the nodes that have been removed, obtain a list of parent-child node relationships corresponding to all the nodes.

[0053] Step 5: The main station generates a topology diagram based on all the superior-subordinate relationships obtained from the processing.

[0054] To ensure that the generated topology diagram includes all meters within the transformer substation area, the topology generation method in this embodiment further includes: after sending a command message to generate a characteristic current to all meters, the master station determines whether any meters are missing; if a meter is missing, the master station sends a separate command message to that missing meter. For example, if the master station determines that any meter in the meter information list is not present in the aforementioned topology diagram, then that meter is considered missing. This avoids the possibility of missing meters and ensures that a topology diagram including all meters within the transformer substation area is obtained.

[0055] Of course, the current information corresponding to the node to be queried can also be displayed based on the node information and the topology diagram, as needed.

[0056] This embodiment provides a readable storage medium storing a computer program, which, when executed by a processor, implements the above-described method for generating transformer area topology relationships.

[0057] This embodiment also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-described method for generating the transformer area topology. In this embodiment, the electronic device is the master station.

[0058] This embodiment also provides a topology relationship generation system for meter characteristic currents, implementing the above-described method for generating transformer area topology relationships. Specifically, see... Figure 2 As shown, the topology relationship generation system for meter characteristic currents in this embodiment includes a main station 1, a concentrator 2, multiple circuit breakers 3, and multiple meters 4. The concentrator 2 is connected to the main station 1; each circuit breaker 3 is connected to the concentrator 2, and each meter 4 is connected to its corresponding circuit breaker 3. Here, the main station 1 executes the above-described method for generating transformer area topology relationships.
