TECHNICAL FIELD

[0001] The present application relates to the technical field of electric metering devices, in particular to a new installation and replacement method of a distributed power access unit. BACKGROUND

[0002] In the field of electric power information collection, accurately and efficiently obtaining information of the distributed power access unit is crucial for power grid management and operation optimization of power enterprises. At present, there are various electric power information collection systems and methods on the market, such as the electric power information collection system and method provided in Chinese patent publication No. CN117014742A, which realizes the function of electric power information collection to a certain extent, but still has many deficiencies.

[0003] In terms of data collection efficiency, the traditional method often needs to go through multi-link approval procedures after the installation of the distributed power access unit, resulting in lag in collecting data and failing to provide timely basis for enterprise decision-making. Moreover, the existing system and related platform are not closely connected, the checking of device asset information is cumbersome, and information sharing between departments within the enterprise is difficult, which affects work efficiency.

[0004] In terms of online loss calculation and power grid operation, the existing technology is difficult to automatically and timely collect the distributed power access unit to the corresponding area and line, and the line loss data is inaccurate and not timely, so that the power enterprise cannot accurately grasp the operation status of the power grid and it is difficult to develop effective operation strategies. In addition, there are many manual operation links and complex operation processes, which increases the cost of manpower and time and reduces the overall work efficiency. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the deficiencies of the prior art and provide a new installation and replacement method of a distributed power access unit.

[0006] The technical solution adopted by the present application is as follows: A new installation method of a distributed power access unit, applied to a system environment composed of a distributed power access unit, a concentrator, a collection system and a metering intelligent industrial control platform, to participate in line loss calculation by being collected to the corresponding area and line, the new installation method comprising the following steps: S1, after the power-on of the access unit of the distributed power, the communication module STA of the distributed power obtains the address of the access unit as the communication address, and sends the network access application to the central coordinator CCO of the concentrator; S2, after the communication module STA successfully accesses the network, the device information of the access unit is obtained, including the communication address and the communication protocol type, and is actively reported to the concentrator; S3, the concentrator receives the reported device information, and compares with the archives in the concentrator, if it is a new device, a discovery unknown electric energy meter event is generated and reported to the acquisition system; S4, after the acquisition system receives the discovery unknown electric energy meter event reported by the concentrator, the access unit asset archives in the metering intelligent industrial control platform are checked to obtain asset information; S5, the acquisition system builds archives, stores the hanging relationship of the concentrator and the access unit, and notifies the front-end and updates the cache; S6, the acquisition system generates and issues meter reading parameters, initiates a debugging process, transmits the voltage of the photovoltaic inverter hung by the acquisition to the access unit for time calibration, after successful time calibration, the acquisition system feeds back the debugging result to the back clip; S7, the acquisition system adjusts the device Internet of Things relationship by using the physical topology identification technology and HPLC transformer identification technology.

[0007] The technical scheme realizes preliminary identification and network access of the device by the communication module STA of the distributed power access unit automatically obtaining and reporting the communication address and device information to the concentrator after power-on; the concentrator compares the archives and reports the unknown device event to the acquisition system, triggers the asset information checking process of the system and the metering intelligent industrial control platform, and ensures the accuracy and integrity of the device information; the acquisition system builds archives and stores the device hanging relationship, and simultaneously generates and issues meter reading parameters, initiates remote debugging, realizes instant data acquisition and time calibration of the device; finally, the device Internet of Things relationship is dynamically adjusted by using the physical topology and HPLC transformer identification technology, so that the distributed power access unit can be accurately collected to the corresponding transformer area and line, effectively participate in line loss calculation, and thus an efficient, automatic and accurate distributed power access and management system is constructed.

[0008] In addition, the instant installation and acquisition method for the new installation and replacement of the distributed power access unit according to the above-mentioned technical scheme of the application can also have the following additional technical features: According to an embodiment of the application, in the step S2, the communication module STA supports the function of periodically reading the hung device information, and actively reports the read information to the concentrator.

[0009] In the technical scheme, the communication module STA periodically reads and actively reports, so that the concentrator can timely master the hung device information, avoid information lag, and ensure the timeliness of power grid management decision.

[0010] According to an embodiment of the application, in the step S3, the concentrator needs to support the function of periodically reading the device information in the central coordinator CCO, and comparing with the acquisition archives in the concentrator to generate an unknown electric energy meter event, so as to prevent missing.

[0011] This technical solution addresses the generation of unknown energy meter events, enabling managers to quickly locate problems, accurately handle abnormal equipment information, and improve the efficiency of power grid equipment management.

[0012] According to an embodiment of the present invention, in step S4, the acquisition system supports automatic debugging functions, including automatic time synchronization, automatic generation and distribution of meter reading parameters, and automatic collection of real-time voltage data to confirm that the equipment parameters are correctly distributed.

[0013] In this technical solution, automatic time synchronization is used to ensure that the time of each device in the acquisition system is synchronized, so that the data acquisition has a unified time reference; automatic generation and distribution of meter reading parameters is used to accurately configure the acquisition tasks according to different device types and acquisition requirements, so as to ensure the accuracy and relevance of data acquisition; automatic collection of real-time voltage data is used to verify the correctness of the device parameter distribution, and to form a closed-loop management by using real-time data feedback.

[0014] According to an embodiment of the present invention, in step S4, the automatic debugging function includes automatically matching the collection scheme issued by the concentrator according to the user type corresponding to the unknown device, and automatically issuing the collection scheme when the user type is newly added.

[0015] In this technical solution, the system pre-stores data acquisition scheme templates corresponding to different user types. Using data classification and association technology, it establishes a mapping relationship between unknown device information and user types. When a new user type device is identified, the system automatically selects and distributes a suitable data acquisition scheme from the scheme library according to preset rules and algorithms. By increasing the consideration of the diversity and variability of power data acquisition services, the system achieves accurate matching between data acquisition schemes and user types through intelligent means.

[0016] According to an embodiment of the present invention, in step S5, the acquisition system supports the automatic storage function of data from unknown devices, establishes a temporary data storage table, and supports the automatic storage of measurement and acquisition data sent by unknown devices, including curve tables, daily frozen energy value tables, and event tables.

[0017] In this technical solution, when the acquisition system detects an unknown device connecting and uploading data, the automatic storage function is immediately activated. The system first creates a temporary data storage table as the initial storage area for the unknown device's data. For different types of data uploaded by the unknown device, the acquisition system performs targeted processing. Measurement data, such as real-time voltage and current, are directly stored in the corresponding area of ​​the temporary data storage table. The system further categorizes and stores the data according to its characteristics. A curve table records the measurement data of the device changing over time; the system organizes the measurement data and stores it in the curve table at preset time intervals to reflect the dynamic changes in the device's status. A daily frozen energy value table stores the energy value at specific times each day; the system extracts relevant data at fixed times each day and stores it in this table. An event table records various event information occurring on the device; when the unknown device generates an event and uploads data, the system stores this event data in the event table. The entire process is completed automatically without manual intervention. According to an embodiment of the present invention, in step S6, the data acquisition system supports WEB functionality and supports querying relevant information, debugging results, data and statistical information of unknown devices by unit, time period, device type, station area / user name, concentrator address / asset number, which facilitates user management and monitoring.

[0018] In this technical solution, when a user needs to query information about unknown devices, they can initiate the operation using the web function of the data acquisition system. After entering the web interface, the user selects the appropriate query dimension according to their needs in the query condition input area. If querying by unit, the system will filter out all relevant records of unknown devices under that unit in the database. When querying by time period, the system will accurately locate the activity information of unknown devices within the selected time period. After selecting the device type, only the details of unknown devices of that type will be displayed. Entering the area / user name can quickly obtain the data of unknown devices in the corresponding area. Entering the concentrator address / asset number can accurately locate the information of unknown devices associated with a specific concentrator. After completing the condition settings and clicking the query button, the system's backend database performs retrieval and matching based on these conditions, extracting the relevant information, debugging results, data, and statistical information of the unknown devices that meet the conditions, and presenting them on the web interface. By viewing this information, users can clearly understand the status and debugging situation of unknown devices, thereby achieving efficient management and real-time monitoring of unknown devices and ensuring the stable operation of the entire data acquisition system.

[0019] To achieve the above objectives, the present invention also provides a method for immediate installation and replacement of distributed power access units.

[0020] A method for immediate replacement of a distributed power access unit, applicable to information changes of already installed distributed power access units, is provided in a system environment consisting of a distributed power access unit, a concentrator, a data acquisition system, and a metering intelligent industrial control platform. The replacement method includes the following steps: S8. On-site personnel will pre-collect and install the new distributed power access unit; S9. After the newly installed distributed power access unit is powered on, the communication module STA performs the steps of network access, equipment information acquisition and reporting. S10. The concentrator receives new device information and compares it with the existing files. If a device change is detected, a device change event is generated and reported to the data acquisition system. S11. After receiving a device change event, the acquisition system updates the connection relationship file of the concentrator and the access unit, and notifies the front-end to update the cache. S12. The data acquisition system regenerates and distributes the meter reading parameters, initiates the debugging process, ensures the new equipment works properly, and feeds back the debugging results to the back clip.

[0021] This technical solution provides the hardware foundation for information changes by having on-site personnel pre-order and install new distributed power access units. After the new unit is powered on, the communication module STA performs network access, equipment information acquisition, and reporting steps, achieving preliminary collection and transmission of new equipment information. The concentrator receives the new equipment information and compares it with the existing files, detects equipment changes, generates equipment change events, and reports them to the acquisition system, completing the preliminary review and transmission of the new equipment information. After receiving the event, the acquisition system updates the connection relationship files and notifies the front-end and updates the cache to ensure the consistency and accuracy of data within the system. Finally, the acquisition system regenerates and distributes meter reading parameters, initiates the debugging process, and feeds back the debugging results to the back clip, completing the configuration and debugging of the new equipment.

[0022] According to an embodiment of the present invention, in step S10, after receiving the equipment change event, the acquisition system performs verification and update of the equipment asset information to ensure that the new equipment information is consistent with the asset file in the metering intelligent industrial control platform.

[0023] According to one embodiment of the present invention, in step S11, after the temporary file is converted into a formal file, the acquisition system automatically migrates the data in the temporary storage table to the production environment.

[0024] Compared with the prior art, the present invention has the following advantages: (1) This invention uses the "install and collect" technology. After the distributed power access unit is newly installed, it can immediately upload key information to the collection system, automatically complete the filing, parameter distribution and collection task allocation, avoid the problem of data lag caused by multiple approvals in the traditional process, and improve the data collection efficiency. The collection system is seamlessly connected with the metering smart industrial control platform to realize the rapid verification of equipment asset information and promote information sharing among various departments within the enterprise. (2) This invention automatically aggregates distributed power access units to corresponding transformer areas and lines to participate in line loss calculation, ensuring the real-time nature of line loss data, enabling power companies to accurately grasp the power grid operation status and optimize operation strategies; it also realizes remote automatic installation and commissioning, reducing on-site manual operation links, simplifying the operation process, reducing manpower and time costs, and improving work efficiency.

S2. After the communication module STA successfully joins the network, it obtains device information from the access unit, including the communication address and communication protocol type, and actively reports it to the concentrator. S3. The concentrator receives the reported device information and compares it with the files in the concentrator. If it is a newly installed device, an unknown energy meter discovery event is generated and reported to the data acquisition system. S4.

[0028] This technical solution enables the distributed power access unit to automatically acquire and report its communication address and device information to the concentrator after power-on, achieving initial device identification and network access. The concentrator then compares the data with the records and reports unknown device events to the acquisition system, triggering an asset information verification process between the system and the intelligent metering control platform to ensure the accuracy and completeness of device information. Based on this, the acquisition system automatically builds its own records and stores device connection relationships, while simultaneously automatically generating and distributing meter reading parameters and initiating remote debugging to achieve real-time data acquisition and time synchronization. Finally, utilizing the physical topology of the distribution area and HPLC distribution area identification technology, the system dynamically adjusts the IoT relationships of the devices, ensuring that the distributed power access unit can be accurately allocated to the corresponding distribution area and line, effectively participating in line loss calculation, thereby constructing an efficient, automatic, and accurate distributed power access and management system.
