[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0027] Figure 1It is a flowchart of a registration method for a distribution terminal provided according to an embodiment of the present invention. This embodiment is applicable to the case where each distribution terminal to be registered is registered through a master station. Optionally, the master station may be an operation and maintenance terminal or a tester for performing maintenance operations on the distribution terminal. The operation and maintenance terminal may receive real-time information sent by the distribution terminal and perform status assessment on the distribution terminal. The tester applies an analog quantity to the distribution terminal to realize the function of testing the distribution terminal. The method may be executed by a registration device of the distribution terminal, and the registration device of the distribution terminal may be implemented in the form of hardware and / or software.

[0028] like Figure 1 As shown, the method of this embodiment is applied to a master station in a distribution network, and may specifically include:

[0029] S110. Upon receiving a registration request sent by a target powered distribution terminal in the distribution network, generate a query request corresponding to the registration request, and send the query request to the target powered distribution terminal.

[0030] Among them, the target powered-on distribution terminal may be a distribution terminal that has completed the power-on operation. Optionally, the target powered-on distribution terminal is a distribution terminal that performs the power-on operation within a preset time period. The preset time period is a time period of a preset length from the current moment. For example, the distribution terminal in the distribution network that was newly powered on within the last hour from the current moment can be used as the target powered-on distribution terminal, thereby completing the registration operation of the newly powered-on distribution terminal. The registration request is a request for applying for registration to the master station. The query request is used to query the information of the target powered-on distribution terminal.

[0031] In a specific implementation, after the target power-on distribution terminal performs the power-on operation, in order to further perform the power distribution test, a registration request may be sent to the master station. Optionally, the registration request includes at least one of the Internet Protocol address, communication port, version information and unique identification name of the target power-on distribution terminal. Through the registration request, the master station obtains at least one of the Internet Protocol address, communication port, version information and unique identification name of the target power-on distribution terminal that needs to be registered. Through the registration request, a query request for obtaining information of the target power-on distribution terminal is generated, and the query request includes the name and / or Internet Protocol address of the master station. Based on the Internet Protocol address, communication port and unique identification name in the registration request, the query request is sent to the target power-on distribution terminal.

[0032] S120: Receive a target information model corresponding to the query request sent by the target power-on distribution terminal, and perform a registration operation on the target power-on distribution terminal based on the target information model.

[0033] Optionally, the query request is a request for querying a target information model pre-built by the target power distribution terminal; the target information model is a mathematical model established based on the functional classification information of the target power distribution terminal. The functional classification information of the target power distribution terminal can be reflected through the target information model, that is, the description of the target power distribution terminal itself can be understood through the target information model. It should be noted that the target information model can be obtained by modeling the distribution terminal through the object-oriented modeling concept of IEC61850.

[0034] In this embodiment, the target powered-on distribution terminal includes a distribution terminal that performs a power-on operation within a preset time period; after receiving the query request, the target powered-on distribution terminal may send a pre-built target information model to a master station in the distribution network. After receiving the target information model, the master station performs a registration operation on the target powered-on distribution terminal based on the target information model in the following ways: if the pre-stored terminal information library does not contain the target terminal information of the target powered-on distribution terminal, add the target terminal information to the terminal information library; enter the target information model into the model database according to the information object address to complete the registration operation on the target powered-on distribution terminal.

[0035] It should be noted that the master station pre-stores a terminal database and a model database. The terminal database is used to store terminal information of distribution terminals that have established connections with the master station. The model database is used to store received information models.

[0036] In a specific implementation, after receiving the target information model, it can be determined whether the target terminal information is stored in the terminal information library; if the target terminal information does not exist, it means that the target power distribution terminal has not performed a registration operation, then the target terminal information of the target power distribution terminal can be added to the terminal information library, and the target information model is entered into the model database according to the information object address, thereby completing the registration operation of the target power distribution terminal. It should be noted that the information object address is a pre-specified storage address of the information model.

[0037] Alternatively, a registration operation for the target power-on distribution terminal is performed based on the target information model, including: when the target terminal information of the target power-on distribution terminal is included in the pre-stored terminal information library, obtaining the historical information model corresponding to the target terminal information in the model database; when the target information model is inconsistent with the historical information model, updating the historical information model based on the target information model to complete the registration operation for the target power-on distribution terminal; generating an update log corresponding to the target information model, and generating an alarm message to send to the operation and maintenance terminal.

[0038] In a specific implementation, if the terminal information library contains the target terminal information of the target powered-on distribution terminal, it means that the target powered-on distribution terminal is a distribution terminal that has been registered and then powered off, and the historical information model corresponding to the target terminal information can be directly determined in the model database. If the historical information model is consistent with the target information model, it means that the functional classification information of the target powered-on distribution terminal has not changed, and the real-time working information of the target powered-on distribution terminal can be directly obtained to perform operation and maintenance operations on the target powered-on distribution terminal. If the historical information model is inconsistent with the target information model, it means that the functional classification information of the target powered-on distribution terminal has changed. In order to accurately obtain the information of the target powered-on distribution terminal, the historical information model can be updated based on the target information model.

[0039] Specifically, the historical information model can be replaced with the target information model; or, the historical information model can be compared with the target information model, and the description of each information object address can be compared in turn to see if they are consistent. For inconsistent information object addresses, the first information corresponding to the information object address in the historical information model can be replaced with the second information corresponding to the information object address in the target information model to complete the update of the historical information model. Exemplarily, if the configuration information version number description is changed, the description information under the corresponding information object address is updated, and the update of the historical information model is completed.

[0040] Furthermore, in order to ensure the security of the distribution network, an update log corresponding to the target information model can be generated after the historical information model is updated, and the specific changes to the historical information model can be understood through the update log. In order to ensure that the update operation is a compliant operation, an alarm message can be generated based on the update log and sent to the operation and maintenance terminal, so that the operation and maintenance personnel can view the alarm message in time and determine whether the update operation is compliant based on the update log.

[0041] This embodiment provides a method for registering the target powered-on and power distribution terminal for two different situations of whether the target terminal information exists in the terminal database, thereby improving the registration flexibility.

[0042] The technical solution of the embodiment of the present invention is applied to a master station in a distribution network. When a registration request is received from a target power-on distribution terminal in the distribution network, a query request corresponding to the registration request is generated, and the query request is sent to the target power-on distribution terminal; a target information model pre-constructed in the target power-on distribution terminal is queried through the query request, and a target information model corresponding to the query request is received from the target power-on distribution terminal. Since the target information model is a mathematical model established based on the functional classification information of the target power-on distribution terminal, no manual operation is required, and the functional classification information of the target power-on distribution terminal is obtained through the received target information model, thereby reducing the workload of the staff; the registration operation of the target power-on distribution terminal is performed based on the target information model, thereby achieving the effect of improving the work efficiency and accuracy in the registration process of the distribution terminal.

[0043] Figure 2 It is a flowchart of another registration method for distribution terminals provided according to an embodiment of the present invention. Based on the above embodiments, this embodiment also includes: upon receiving an application association service request sent by at least one distribution terminal, establishing a bilateral application association with at least one distribution terminal; sending a target message for obtaining a pre-built information model of the distribution terminal to at least one distribution terminal; receiving the information model and terminal information corresponding to the target message sent by the distribution terminal, building a terminal information library based on the terminal information, and building a model database based on the terminal information. Among them, the explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0044] S210. Upon receiving an application association service request sent by at least one power distribution terminal, establish a bilateral application association with at least one power distribution terminal.

[0045] The application association service request is a request for requesting to establish an association service with the primary station.

[0046] In a specific implementation, the master station may simultaneously receive application association service requests sent by multiple distribution terminals, and the application association service request may include terminal information of the distribution terminal, and the terminal information includes at least one of an Internet Protocol address, a communication port, version information, and a unique identification name. When the master station receives the application association service request, it may determine whether the distribution terminal that sends the application association service request is a compliant device. If it is a compliant device, a bilateral application association is established with the distribution terminal. If it is not a compliant device, in order to ensure the safety of the distribution network, the terminal information of the distribution terminal may be recorded for alarm processing.

[0047] In this embodiment, the power distribution terminal can pre-generate an information model based on the functional classification information. The information model includes a data acquisition and monitoring control module, a protection module, a remote maintenance module, and a real-time monitoring module; the data acquisition and monitoring control module, the protection module, the remote maintenance module, and the real-time monitoring module respectively include a first logical node and a second logical node; the first logical node is used to store common information between modules, and the second logical node is used to store information of logical devices corresponding to the module.

[0048] The remote maintenance module is used to implement the first fixed value issuance of the time-limited overcurrent and the second fixed value issuance of the inverse time-limited overcurrent of the distribution terminal. The data acquisition and monitoring control module, the remote maintenance module and the real-time monitoring module all include a battery maintenance unit for remote on-site maintenance of the battery in the distribution terminal. The real-time monitoring module includes a gas insulation monitoring unit and a liquid insulation monitoring unit. The remote maintenance module and the real-time monitoring module both include an overheating logic node. The data acquisition and monitoring control module and the real-time monitoring module both include a judgment node. The judgment node is used to monitor the unbalanced voltage and current to determine whether the voltage transformer and the current transformer are disconnected. The real-time monitoring module also includes a terminal status monitoring general logic node, which is used to uniformly model the monitoring quantities that cannot be mapped to the logical nodes in the IEC 61850-7-4 protocol. The gas insulation monitoring unit is used to detect the gas insulation medium, and the liquid insulation monitoring unit is used to detect the liquid insulation medium. The overheating logic node is used to detect whether there is an overheating condition.

[0049] S220. Send a target message for obtaining a pre-built information model of the distribution terminal to at least one distribution terminal; receive the information model and terminal information corresponding to the target message sent by the distribution terminal, build a terminal information library based on the terminal information, and build a model database based on the terminal information.

[0050] In a specific implementation, for a distribution terminal that has established a bilateral application association, the master station obtains the model name, version number, logical state, physical state, and capability list of the distribution terminal, and sends a target message to the distribution terminal. The target message is a message for obtaining an information model. Specifically, a target message for obtaining a pre-built information model of a distribution terminal is sent to at least one distribution terminal, including: for each distribution terminal, generating a target message for obtaining a pre-built information model of the distribution terminal according to a preset format; wherein the preset format includes at least one field of a start character, a message length, a control field, a type identifier, a variable structure qualifier, a transmission reason, an application data service unit public address, and an information object address; and sending a target message corresponding to each distribution terminal.

[0051] It should be noted that, from the working mode of the distribution terminal, the information exchange of the distribution terminal is mainly through the communication between it and the master station. The preset format can adopt the message format of the 104 protocol. Furthermore, on the basis of the 104 protocol, an application data service unit can be expanded to adopt an octet string as a data type to transmit the description of the corresponding information body. After the distribution terminal is connected to the master station, the information model of the distribution terminal is arranged according to the information object address and waits for the call command of the master station.

[0052] In this embodiment, the format of the response message sent by the distribution terminal may be: message length, control field, type identifier, variable structure qualifier, transmission reason, application data service unit public address, information object address, octet string length and octet string.

[0053] In a specific implementation, the information model and terminal information corresponding to the target message sent by the distribution terminal are received, and a terminal information library for storing the received terminal information is constructed, and a model database for storing the received information model is constructed. Through the model database, during the real-time communication between the master station and the distribution terminal, it is not necessary to carry the self-description information every time. The self-description information of the distribution terminal can be determined through the information model stored in the model database, thereby saving network bandwidth. When the information model of the distribution terminal changes, the changed information model is obtained online by executing application association operations, reading the server directory, reading the logical device directory, reading the logical node directory, reading the data directory, and reading the data definition service.

[0054] S230. Upon receiving a registration request sent by a target powered distribution terminal in the distribution network, generate a query request corresponding to the registration request, and send the query request to the target powered distribution terminal.

[0055] Optionally, before generating a query request corresponding to the registration request, it also includes: when it is detected that the main station is in a restart state, sending a calling message to at least one pre-associated distribution terminal, so that the called distribution terminal that receives the calling message generates a called information model according to the calling format requirements of the calling message, and sends the called information model to the main station.

[0056] In order to avoid the loss of stored information due to the restart of the master station, when it is detected that the master station is in a restart state, a calling message can be sent to at least one pre-associated distribution terminal after the master station restarts. The calling message is used to obtain the information model of the distribution terminal. The calling message and the target message can use the same format. The distribution terminal that receives the calling message is called the called distribution terminal. After receiving the calling message, the called distribution terminal generates a called information model according to the calling format requirements and sends the called information model to the master station. The calling format requirements are used to indicate the composition format of the information model. Exemplarily, the composition format includes servers, logical devices, logical nodes, data, data attributes, and attribute definitions.

[0057] This embodiment reacquires the called information model after detecting that the master station is restarted, so as to avoid the loss of the previously stored information model, thereby facilitating better maintenance of the power distribution terminal.

[0058] S240: Receive a target information model corresponding to the query request sent by the target power-on distribution terminal, and perform a registration operation on the target power-on distribution terminal based on the target information model.

[0059] In this embodiment, the target information model is sent to the master station through the target power distribution terminal, so as to realize plug-and-play between the master station and the distribution terminal. It should be noted that the master station can be an operation and maintenance terminal or a relay protection tester. Through the registration method provided in this embodiment, plug-and-play between the relay protection tester or the operation and maintenance terminal is realized.
