[0036] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] It should be noted that the terms "first", "second", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such use can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein. In addition, the term "including" and its variants should be interpreted as open-ended terms meaning "including but not limited to".

[0038] With the rapid development of social economy, the scale of the distribution network is getting larger and larger, gradually showing the characteristics of numerous points, wide area, large number of equipment, wide distribution range, and complex communication environment. The line-transformer relationship refers to the power supply subordination relationship between distribution transformers and each outgoing line of the substation. Due to reasons such as line transformation and load switching, the attribution relationship between lines and substations is unclear. Relying solely on the traditional manual line patrol method to carry out the verification of the distribution network topology structure data is not only time-consuming and laborious, but also unable to update the data in a timely manner. This leads to difficulties in carrying out distribution network operation and maintenance work, and also affects important operations such as fault diagnosis, line loss calculation, and power grid planning, making it difficult to achieve the expected results.

[0039] Therefore, there is an urgent need for a line-transformer relationship automatic correction system to quickly clarify the line-transformer relationship and timely master the topology structure of the distribution network.

[0040] Based on this, this application proposes a line-transformer relationship correction system that uses the cooperation between line-transformer terminals, master station systems, and mobile terminals to manage the line-transformer relationship, enabling timely mastery of the line-transformer relationship of the distribution network, providing guarantees for work such as fault diagnosis, line loss calculation, power grid planning, and distribution network operation and maintenance. At the same time, it also solves the problems of time-consuming and laborious data verification of the distribution network line-transformer relationship by relying on the traditional manual line patrol method and the inability to update the data in a timely manner.

[0041] The following will detail the technical solutions provided by each embodiment of this application in conjunction with the accompanying drawings.

[0042] Figure 1 Figure 1 shows a line-transformer relationship correction system according to an embodiment provided by this application. The line-transformer relationship correction method provided by the embodiment of this application can be implemented through a system as shown in Figure 1 Figure 1.

[0043] As can be seen from Figure 1 Figure 1, the line-transformer relationship correction system includes a line-transformer terminal, a master station system, and a mobile terminal. The master station system establishes communication connections with the line-transformer terminal and the mobile terminal respectively, such as 4G communication connection or 5G communication connection.

[0044] In some embodiments, the line-transformer terminal is composed of a central processing unit, a clock module, an encoding module, a decoding module, a digital-to-analog conversion module, an analog-to-digital conversion module, a carrier communication module, a transmitting module, a receiving module, a 4G / 5G communication module, a positioning module, a USB interface, and an RJ-45 interface, as shown in Figure 2 Figure 1.

[0045] Among them, the central processing unit is the core of the line transformer terminal, which manages and controls the coordinated operation of each functional module in real time through the interface. The clock module uses a high-precision clock chip to ensure the accuracy of the system clock and accurately record the time of changes in the line transformer relationship. The encoding module compiles and converts the information or data to be sent by the line transformer terminal into a signal form that can be used for communication, transmission, and storage. The decoding module accurately extracts information or data from the signals received by the line transformer terminal. The digital-to-analog conversion module converts the digital signals storing information and data into analog signals. The analog-to-digital conversion module converts the analog signals storing information and data into digital signals. The carrier communication module can generate or receive power line carrier signals with different intensities and frequencies. The transmitting module transmits the carrier signals storing information and data from the line transformer terminal to the power line. The receiving module receives the carrier signals storing information and data on the power line into the line transformer terminal. The 4G / 5G communication module is a communication form used between the line transformer terminal and the master station system, and between the master station system and the mobile terminal. The positioning module has GPS or Beidou positioning functions, can read the longitude and latitude information of the location where the line transformer terminal is located in real time, and the master station system can send commands to the line transformer terminal to read the specific location of the line transformer terminal, so as to know the location of the transformer where the line transformer terminal is located. The UBS interface is used for data transmission and can be connected to USB storage devices such as mobile hard disks and USB flash drives of USB 3.0 or USB 2.0 for data backup, synchronization, and migration. The RJ-45 interface can be connected to a computer through a network cable, and maintenance personnel can operate the computer to adjust the relevant parameter information of the line transformer terminal.

[0046] Specifically, according to different installation positions, the line transformer terminal can be divided into in-station line transformer terminals and substation area line transformer terminals. As Figure 3 shown, the in-station line transformer terminals are installed on the line side of each outgoing line in the substation, and the substation area line transformer terminals are installed on the high-voltage side of the distribution transformer. The in-station line transformer terminals and the substation area line transformer terminals establish a two-way connection based on the power line carrier.

[0047] In some embodiments, the master station system is a power supply service command system, and a new module is developed in the system to manage the line transformer relationship in the distribution network. Further, the master station system can also store relevant information of each substation area, such as transformer capacity, transformer ratio of the current transformer, etc. Staff can maintain the line transformer relationship, etc. in the master station system. Other systems, such as PMS, distribution network automation systems, etc. can extract relevant line transformer relationship information and data from the power supply service command system.

[0048] Further, when the line transformer relationship is changed and the line transformer relationship information of the in-station line transformer terminal and the substation area line transformer terminal is inconsistent, an abnormal message will be sent to the master station system. After the master station system receives the abnormal message and determines that the line transformer relationship is abnormal, it will send an alarm message to the mobile terminal.

[0049] In some embodiments, the mobile terminal is the mobile end of the master station system, capable of managing the line-transformer relationship in the distribution network and viewing relevant information of each substation area, such as transformer capacity, current transformer ratio, etc. The mobile terminal can not only receive alarm information sent by the master station system, but also maintain the line-transformer relationship and then transmit it to the master station system.

[0050] Furthermore, after the line switching or equipment replacement, the staff can correct and maintain the relevant information of each substation area in the mobile terminal, and the maintained information will be automatically transmitted to the master station system through 4G / 5G communication.

[0051] In the embodiments of the present application, if the line-transformer relationship information of the in-station line-transformer terminal and the substation area line-transformer terminal is inconsistent, an abnormal message will be sent to the master station system. After receiving the abnormal message and determining that the line-transformer relationship is abnormal, the master station system will send an alarm message to the mobile terminal, so as to manage the line-transformer relationship through the cooperation among the line-transformer terminal, the master station system and the mobile terminal, be able to timely grasp the abnormalities of the distribution network and correct the abnormalities in time, and provide guarantee for work such as fault diagnosis, line loss calculation, power grid planning, and distribution network operation and maintenance. At the same time, it also solves the problem that the traditional manual line inspection method for verifying the line-transformer relationship data in the distribution network is time-consuming and laborious and cannot update the data in time.

[0052] It should be noted that the present application is not limited to Figure 1 or Figure 2 the line-transformer relationship correction system shown, and any system, device, framework, etc. that can implement the business logic of the present application are acceptable, Figure 1 or Figure 2 which is only for exemplary illustration.

[0053] Figure 4 shows a schematic flow diagram of the line-transformer relationship correction system according to an embodiment provided by the present application. As can be seen from Figure 4 it, the method may include steps S101 to S104:

[0054] Step S101: The line-transformer terminal sends an abnormal message to the master station system.

[0055] Among them, the abnormal message is used to indicate the abnormal line-transformer relationship. For example, the abnormal message includes Substation No. 1, Outlet No. 3, and Substation Area No. 2.

[0056] Step S102: The master station system determines whether the line-transformer relationship is abnormal based on the abnormal message.

[0057] For example, if the abnormal message includes Substation No. 1, Outlet No. 3, and Substation Area No. 2, the master station system determines whether the line-transformer relationship to which Substation No. 1, Outlet No. 3, and Substation Area No. 2 belongs is abnormal based on the abnormal message.

[0058] Step S103: When the master station system determines that the line-transformer relationship is abnormal, it sends an alarm message to the mobile terminal.

[0059] The alarm message is used to indicate that the line-transformer relationship is abnormal.

[0060] Step S104: The master station system and / or the mobile terminal correct the line-transformer relationship based on the alarm message.

[0061] In some embodiments, the operation and maintenance personnel can correct the line-transformer relationship on the mobile terminal, or ignore the alarm message. After a preset time when the master station system sends the alarm message, the master station system automatically corrects the line-transformer relationship and sends a message to change the line-transformer relationship to the line-transformer terminal, and the line-transformer terminal changes the line-transformer relationship by itself.

[0062] In the embodiments of the present application, the line-transformer terminal determines that the line-transformer relationship is abnormal and sends an abnormal message to the master station system. The master station system determines whether the line-transformer relationship is abnormal based on the abnormal message. When it determines that the line-transformer relationship is abnormal, it sends an alarm message to the mobile terminal, so that the operation and maintenance personnel can correct the abnormal line-transformer relationship through the master station system or the mobile terminal based on the alarm message, thereby using the cooperation between the line-transformer terminal, the master station system and the mobile terminal to manage the line-transformer relationship, being able to timely master the abnormalities of the distribution network and timely correct the abnormalities, providing guarantee for work such as fault diagnosis, line loss calculation, power grid planning, and distribution network operation and maintenance. At the same time, it also solves the problem that it takes time and effort to carry out data verification of the line-transformer relationship of the distribution network by relying on the traditional manual line patrol method and it is impossible to update the data in time.

[0063] In some embodiments of the present application, in combination with the in-station line-transformer terminal and the substation area line-transformer terminal, step S101 where the line-transformer terminal sends an abnormal message to the master station system is described.

[0064] As Figure 5 shown, Figure 5 shows a schematic flow diagram of an abnormal message sending method according to an embodiment provided by the present application, including the following steps S201 - step S206:

[0065] Step S201: The in-station line-transformer terminal sends the first line-transformer information to the substation area line-transformer terminal.

[0066] The first line-transformer information represents the current line-transformer relationship of the in-station line-transformer terminal. For example, the content included in the first line-transformer information is: the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, then the current line-transformer relationship of the in-station line-transformer terminal is that the 3rd transformer substation area belongs to the 2nd outgoing line of the 1st substation.

[0067] Step S202: The substation area line-transformer terminal determines the first comparison result based on the first line-transformer information.

[0068] Among them, the first comparison result indicates whether the line transformation information of the first line is consistent with the line transformation relationship of the in-station line transformation terminal stored in the substation area line transformation terminal.

[0069] For example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the line transformation relationship of the in-station line transformation terminal stored in the substation area line transformation terminal is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, then the first comparison result is consistent. Another example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the line transformation relationship of the in-station line transformation terminal stored in the substation area line transformation terminal is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation, then the first comparison result is inconsistent.

[0070] Step S203: If the first comparison result is inconsistent, the substation area line transformation terminal sends the second line transformation information to the in-station line transformation terminal.

[0071] Among them, the second line transformation information represents the line transformation relationship stored in the substation area line transformation terminal. For example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the line transformation relationship of the in-station line transformation terminal stored in the substation area line transformation terminal is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation, and the first comparison result is inconsistent, then the second line transformation information is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation.

[0072] Step S204: If the first comparison result is inconsistent, the substation area line transformation terminal sends the first abnormal message to the master station system.

[0073] Among them, the first abnormal message represents the line transformation relationship stored in the substation area line transformation terminal. For example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the line transformation relationship of the in-station line transformation terminal stored in the substation area line transformation terminal is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation, and the first comparison result is inconsistent, then the first abnormal message is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation.

[0074] Step S205: The in-station line transformation terminal determines the second comparison result based on the first line transformation information and the second line transformation information.

[0075] Among them, the second comparison result indicates whether the first line transformation information and the second line transformation information are consistent.

[0076] For example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the second line transformation information is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, then the second comparison result is consistent. Another example, if the line transformation information of the first line is the 3rd transformer substation area of the 2nd outgoing line of the 1st substation, and the second line transformation information is the 3rd transformer substation area of the 2nd outgoing line of the 2nd substation, then the second comparison result is inconsistent.

[0077] Step S206: If the second comparison result is inconsistent, the in-station line-transformer terminal sends a second exception message to the master station system.

[0078] Among them, the second exception message represents the current line-transformer relationship of the in-station line-transformer terminal. For example, if the first line-transformer information is the 3rd transformer area of the 2nd outgoing line of the 1st substation, the second line-transformer information is the 3rd transformer area of the 2nd outgoing line of the 2nd substation, and the second comparison result is inconsistent, then the second exception message is the 3rd transformer area of the 2nd outgoing line of the 1st substation.

[0079] In the embodiment of the present application, when the line-transformer information of the in-station line-transformer terminal is inconsistent with the line-transformer information of the substation area line-transformer terminal, both the in-station line-transformer terminal and the substation area line-transformer terminal will send exception messages to the master station system, so that the master station system can confirm whether the line-transformer relationship is abnormal based on the exception messages.

[0080] In other embodiments of the present application, in combination with the in-station line-transformer terminal and the substation area line-transformer terminal, when the line is switched, how the in-station line-transformer terminal and the substation area line-transformer terminal send exception messages to the master station system is described.

[0081] As Figure 6 shown, Figure 6 FIG. shows a schematic flow chart of an exception message sending method according to an embodiment provided by the present application, including the following steps S301 - step S308:

[0082] Step S301: After the substation area line-transformer terminal resumes from the power-off state to the working state, the substation area line-transformer terminal sends the third line-transformer information to the in-station line-transformer terminal.

[0083] Among them, the third line-transformer information represents the current line-transformer relationship of the substation area line-transformer terminal.

[0084] For example, if the outgoing line 1 of the 1st substation is powered off, resulting in the power-off of the 1st area, when the tie switch between the outgoing line 1 and the outgoing line 2 is closed, the 1st area resumes power supply. After the substation area line-transformer terminal resumes from the power-off state to the working state, at this time, the substation area line-transformer terminal sends the third line-transformer information to the in-station line-transformer terminal, and the third line-transformer information includes the 1st area of the outgoing line 2 of the 1st substation.

[0085] Step S302: The in-station line-transformer terminal determines a fourth comparison result based on the third line-transformer information.

[0086] Among them, the fourth comparison result represents whether the third line-transformer information is consistent with the line-transformer relationship stored in the in-station line-transformer terminal.

[0087] For example, if the third line-transformer information includes the 1st area of the outgoing line 2 of the 1st substation, while the line-transformer relationship stored in the in-station line-transformer terminal should be the 1st area of the outgoing line 1 of the 1st substation, at this time, the fourth comparison result is inconsistent.

[0088] Step S303: If the fourth comparison result is inconsistent, the substation line transformer terminal sends the first line transformer information to the substation area line transformer terminal.

[0089] Step S304: The substation area line transformer terminal determines the first comparison result based on the first line transformer information.

[0090] Step S305: If the first comparison result is inconsistent, the substation area line transformer terminal sends the second line transformer information to the substation line transformer terminal.

[0091] Step S306: If the first comparison result is inconsistent, the substation area line transformer terminal sends the first abnormal message to the master station system.

[0092] Step S307: The substation line transformer terminal determines the second comparison result based on the first line transformer information and the second line transformer information.

[0093] Step S308: If the second comparison result is inconsistent, the substation line transformer terminal sends the second abnormal message to the master station system.

[0094] For the specific implementation manners of Steps S303 - S308, reference may be made to the above Steps S201 - S206, and details are not described herein again in the embodiments of the present application.

[0095] In the embodiments of the present application, when a line switching occurs, the substation area line transformer terminal triggers the sending of an abnormal message, so that the master station system determines whether the line transformer relationship is abnormal based on the abnormal message.

[0096] The following takes Figure 7 as an example to illustrate the situation of line switching. The passive working mode of the line transformer relationship correction system is as follows:

[0097] When the line switching is carried out, the 10kV outgoing line 1 will be powered off, resulting in the power outage of the 102 transformer substation, and the terminal of the transformer and line in the substation area stops working. Close the tie switch between the 10kV outgoing line 1 and the 10kV outgoing line 2, and the 102 transformer substation resumes power supply, and the terminal of the transformer and line in the substation area works again. After the terminal of the transformer and line in the 102 substation area resumes working, it first sends the transformer and line information to the terminal in the station to determine the belonging line of this substation area. The transformer and line information is transmitted along the power line to the terminal of the transformer and line in the station on the 10kV outgoing line 2 of the substation. After receiving the transformer and line information, the terminal of the transformer and line in the station compares it with the transformer and line information stored in itself, and will find that the messages are inconsistent. At this time, the terminal of the transformer and line in the station on the 10kV outgoing line 2 sends the transformer and line information to the terminal of the transformer and line in the 102 substation area again. After receiving the transformer and line information, the terminal of the transformer and line in the 102 substation area compares the transformer and line information with the transformer and line information stored in itself, and will find that the two pieces of transformer and line information are inconsistent. At this time, the terminal of the transformer and line in the substation area not only sends the transformer and line information to the terminal of the transformer and line in the station, but also sends an abnormal message to the master station system through the 4G / 5G communication method. After receiving the transformer and line information, the terminal of the transformer and line in the station compares the transformer and line information with the previous sent transformer and line information, confirms that the two pieces of transformer and line information are indeed inconsistent, and the terminal of the transformer and line in the station will send a message to the master station. After receiving the transformer and line information of the terminal of the transformer and line in the station on the 10kV outgoing line 2 and the terminal of the transformer and line in the 102 substation area, the master station system compares them again. If the two pieces of transformer and line information are indeed inconsistent, it will send an alarm message to the mobile terminal through the 4G / 5G communication method for the line operation and maintenance personnel to judge. The line operation and maintenance personnel can confirm the change of the transformer and line relationship on the mobile terminal, or ignore the alarm message. After 30 minutes of the warning from the master station system, the master station system automatically changes the transformer and line relationship, and at the same time sends a change message for changing the transformer and line relationship to the terminal of the transformer and line in this substation area and the terminal in the station, and the terminal of the transformer and line changes it by itself.

[0098] The following takes Figure 7 as an example to illustrate the situation of line switching. The active working mode of the device for correcting the transformer and line relationship is as follows:

[0099] When the line switching is carried out, the 10kV outgoing line 1 will be powered off, resulting in the power outage of the 102 transformer substation, and the terminal of the transformer and line in the substation area stops working. The line operation and maintenance personnel change the line belonging of the 102 transformer substation in the mobile terminal or the master station system, and the master station system sends the changed transformer and line information to the terminal of the transformer and line in the station on the 10kV outgoing line 2 and the terminal of the transformer and line in the 102 substation area through the 4G / 5G communication method. After receiving the changed transformer and line information, the terminal of the transformer and line in the station on the 10kV outgoing line 2 updates its own message. Close the tie switch between the 10kV outgoing line 1 and the 10kV outgoing line 2, and the 102 transformer substation resumes power supply, and the terminal of the transformer and line in the substation area works again. At this time, the terminal of the transformer and line in the substation area will receive the changed transformer and line information sent by the master station system and correct its own line belonging.

[0100] In addition, under normal line operation conditions, the in-station line-transformer terminal sends line-transformer information to the substation area line-transformer terminal. This line-transformer information is transmitted to each substation area under this line using power line carrier communication technology. After receiving the line-transformer information, the substation area line-transformer terminal compares the received line-transformer information with the line-transformer information stored in itself. If the two pieces of line-transformer information are consistent, the substation area line-transformer terminal sends the line-transformer information stored in itself to the in-station line-transformer terminal. This line-transformer information is also transmitted to the in-station line-transformer terminal using power line carrier communication technology. After receiving the line-transformer information, the in-station line-transformer terminal compares the received line-transformer information with the line-transformer information sent by the in-station line-transformer terminal last time. If the two pieces of line-transformer information are consistent, it is determined that this substation area belongs to this line and the line-transformer relationship is normal, and there is no need to send an abnormal message to the master station system.

[0101] In some embodiments of the present application, in combination with the first abnormal message sent by the in-station line-transformer terminal and the second abnormal message sent by the substation area line-transformer terminal, an explanation is given on whether the line-transformer relationship determined by the master station system based on the abnormal message in step S102 is abnormal:

[0102] The master station system determines a third comparison result based on the first abnormal message and the second abnormal message. The third comparison result indicates whether the first abnormal message is consistent with the second abnormal message; if the third comparison result indicates that the first abnormal message is inconsistent with the second abnormal message, the master station system determines that the line-transformer relationship is abnormal and sends an alarm message to the mobile terminal. If the third comparison result indicates that the first abnormal message is consistent with the second abnormal message, the master station system determines that the line-transformer relationship is normal, and at this time, the master station system does not send an alarm message to the mobile terminal.

[0103] Furthermore, after receiving the alarm message, the master station system will send an alarm message to the mobile terminal. If the operation and maintenance personnel correct the line-transformer relationship through the mobile terminal within the preset time, the mobile terminal sends a first correction message to the master station system. The first correction message is used to indicate the line-transformer relationship corrected by the operation and maintenance personnel. The master station system sends the first correction message to the substation area line-transformer terminal and the in-station line-transformer terminal, so that the substation area line-transformer terminal and the in-station line-transformer terminal correct the line-transformer relationship based on the first correction message. Or, if the operation and maintenance personnel do not correct the line-transformer relationship through the mobile terminal within the preset time, the master station system will automatically correct the line-transformer relationship and send a second correction message to the substation area line-transformer terminal and the in-station line-transformer terminal to indicate the substation area to which the in-station line-transformer terminal belongs. The substation area line-transformer terminal and the in-station line-transformer terminal correct the line-transformer relationship based on the second correction message.

[0104] Even further, the master station system and / or the mobile terminal send positioning information to the line-transformer terminal to obtain the position of the transformer to which the line-transformer terminal belongs, so that it is convenient for the operation and maintenance personnel to perform on-site maintenance.

[0105] Next, the line-transformer relationship correction system proposed in the present application will be described separately from the aspects of the in-station line-transformer terminal, the substation area line-transformer terminal, the master station system, and the mobile terminal.
