Description

A method and system for managing data from new energy power stations Technical Field

[0001] This invention belongs to the field of new energy power station data management, specifically relating to a method and system for managing new energy power station data. Background Technology

[0002] With the accelerated construction of new power systems and the continuous increase in the proportion of installed capacity of new energy sources, the number of wind power stations, photovoltaic power stations, and energy storage power stations under the jurisdiction of power generation groups has increased significantly, and a "one region, multiple stations" layout and operation management architecture is generally adopted. Against this backdrop, key equipment in new energy power stations, including wind turbines, photovoltaic inverters, box-type transformers, and energy storage converters (PCS), is experiencing rapid iteration in its equipment management and data access capabilities. While the construction of regional centralized control systems has enabled centralized collection and analysis of data from new energy power stations, effectively improving energy utilization efficiency and management effectiveness, the heterogeneous nature and spatially dispersed characteristics of new energy power station equipment present challenges to traditional operation and maintenance management models, such as increased difficulty in managing the entire lifecycle of equipment and delayed operation and maintenance responses. Simultaneously, the accumulation of massive amounts of heterogeneous data in regional centralized control systems, constrained by imperfect data governance systems and lagging analysis and mining technologies, has not yet formed a value loop supporting scenarios such as equipment health diagnosis and risk warning. The ability to mine data value and apply it in depth urgently needs to be enhanced.

[0003] Chinese invention patent application CN111049264A discloses a cloud-based energy management system, comprising: a cloud management center and several regional control centers communicatively connected to the cloud management center; and new energy substations communicatively connected to the regional control centers. This energy management system enables multi-level management and control. Specifically, multi-level management and control are achieved through the cloud management center and the several regional control centers communicatively connected to the cloud management center; and the new energy substations communicatively connected to the regional control centers. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for managing data from new energy power stations, which addresses the problems of increased difficulty in managing the entire lifecycle of equipment and delayed operation and maintenance response in existing operation and maintenance management models for equipment management and data access at new energy power stations.

[0005] To achieve the above objectives, the present invention provides a method for managing data from new energy power stations, comprising: uploading data from new energy power stations to regional centralized control zone I or II; the data from new energy power stations includes real-time measurement data; after receiving the real-time measurement data, regional centralized control zone I or II synchronizes the real-time measurement data to its database, and determines whether there are any changes in the data of measurement points in the real-time measurement data, and sends the changed data to the message bus in the form of a real-time data message, and then forwards it to regional centralized control zone III through a forward isolation device, and then sends it to the data management subsystem in the form of a real-time data message; after the database of regional centralized control zone I or II synchronizes the real-time measurement data to the database of regional centralized control zone III through the forward isolation device according to a first set period, the database of regional centralized control zone III synchronizes the real-time measurement data to the data management subsystem according to a second set period.

[0006] Furthermore, the data from new energy power stations also includes file data; the management method further includes: different types of file data are uploaded to regional control zones I and II respectively using methods corresponding to file types; the file data from regional control zones I and II are forwarded to regional control zone III in the form of files through a forward isolation device according to the set directory hierarchy; regional control zone III uses SFTP service to periodically pull different types of file data from the data management subsystem and store them in the file database corresponding to the data management subsystem; the set directory hierarchy includes power stations, categories, subcategories, and files, with the power station hierarchy having the highest order, and the order of categories, subcategories, and files decreasing in that order; higher-order levels contain lower-order levels.

[0007] Furthermore, different types of files are uploaded to the regional control zones I and II in a manner corresponding to their file types. For wind turbine vibration monitoring files, an SFTP service is established on the vibration monitoring system, and the files are then retrieved periodically by the regional control zones I and II after being proxied by the edge gateway at the wind farm. For power prediction files uploaded by photovoltaic and wind farms, the IEC102 protocol is used, and the files are uploaded to the regional control zones I and II respectively through the edge gateways at the wind farm and photovoltaic farms. For protection device fault recording files, an SFTP service is established at the protection information substation, and the files are retrieved by the regional control zones I and II after receiving the message, proxied by the edge gateway at the booster station.

[0008] Furthermore, the directory hierarchy also includes dates, with dates ranking below the site but above the file.

[0009] Furthermore, the data management subsystem is located in the regional centralized control zone III. It is used to receive real-time measurement data and file data sent from various regional centralized control zones, and, in conjunction with information from various sites, including point tables and ledgers, to perform corresponding data storage processing on the real-time measurement data and file data. The data management subsystem has functions for file management, data management, data analysis, point table management, access control, and ledger management. The data management subsystem also provides a common interface for other business systems to access the measurement data and file data stored in the database of the data management subsystem.

[0010] The above-described technical solution of this invention provides a novel method for managing data from new energy power stations. Its beneficial effects include: based on a hierarchical architecture where data from new energy power stations is transmitted to regional control zones I or II, then to regional control zone III, and finally to the data management subsystem, the invention not only synchronizes real-time measurement data collected from new energy power stations in regional control zones I or II to regional control zone III via periodic database synchronization, ensuring the comprehensiveness of measurement data updates, but also allows regional control zones I or II to filter out changed data and send it to the data management subsystem via regional control zone III as real-time data messages. This means that only the changed portion of the measurement data is sent up in real-time. This improves transmission speed by reducing the amount of data transmitted and by minimizing the time and potential slow transmission caused by processing measurement data into other forms, thereby comprehensively improving the real-time performance of measurement data management and avoiding delays in operation and maintenance response.

[0011] This invention also provides a data management system for new energy power stations, including separate management modules for regional centralized control zone I or II, new energy power stations, and regional centralized control zone III. The management modules for regional centralized control zone I or II and the new energy power station management modules are used together to upload data from the new energy power stations to regional centralized control zone I or II. The data from the new energy power stations includes real-time measurement data. The management module for regional centralized control zone I or II is further used to synchronize the real-time measurement data to the database of regional centralized control zone I or II after receiving the real-time measurement data, and to determine whether any changes have occurred in the data of the measurement points within the real-time measurement data. The system sends the changed data to the message bus as a real-time data message, and then forwards it to the regional control zone III via a forward isolation device. The management module of the regional control zone III is also used to send that data to the data management subsystem as a real-time data message. The management module of the regional control zone I or II is also used to synchronize the real-time measurement data from the database of the regional control zone I or II to the database of the regional control zone III via a forward isolation device according to a first set period. The management module of the regional control zone III is also used to control the database of the regional control zone III to synchronize the real-time measurement data to the data management subsystem according to a second set period.

[0012] Furthermore, the data from new energy power stations also includes file data; the management module of the new energy power station is also used to send different types of file data to the regional centralized control zones I and II in a manner corresponding to the file type; the management module of the regional centralized control zone I or II is also used to forward the file data of the regional centralized control zone I and II to the regional centralized control zone III in the form of files through the forward isolation device according to the set directory hierarchy; the set directory hierarchy includes the levels of power station, category, subcategory and file, with the level of power station being the highest, and the level order of category, subcategory and file decreasing in that order; higher-order levels contain lower-order levels; the management module of the regional centralized control zone III is also used to periodically pull different types of file data from the data management subsystem through the SFTP service and store them in the file database of the data management subsystem.

[0013] Furthermore, different types of files are uploaded to the regional control zones I and II in a manner corresponding to their file types. For wind turbine vibration monitoring files, an SFTP service is established on the vibration monitoring system, and the files are then retrieved periodically by the regional control zones I and II after being proxied by the edge gateway at the wind farm. For power prediction files uploaded by photovoltaic and wind farms, the IEC102 protocol is used, and the files are uploaded to the regional control zones I and II respectively through the edge gateways at the wind farm and photovoltaic farms. For protection device fault recording files, an SFTP service is established at the protection information substation, and the files are retrieved by the regional control zones I and II after receiving the message, proxied by the edge gateway at the booster station.

[0014] Furthermore, the directory hierarchy also includes dates, with dates ranking below the site but above the file.

[0015] Furthermore, it also includes a data management subsystem, which is located in the regional centralized control area III. This subsystem receives real-time measurement data and file data from various regional centralized control systems and, in conjunction with information from each site, including point tables and ledgers, processes the real-time measurement data and file data to be stored in the database. The data management subsystem has functions for file management, data management, data analysis, point table management, access control, and ledger management. The data management subsystem also provides a common interface for other business systems to access the measurement data and file data stored in the database of the data management subsystem.

[0016] The technical solution of the new energy power station data management system described above can achieve the same beneficial effects as the new energy power station data management method described above. Attached Figure Description

[0017] Figure 1 is an example of the architecture applicable to the data management method for new energy power stations in the implementation method of the present invention; Figure 2 is an example of the steps of the data management method for new energy power stations, which mainly involves real-time measurement data, in the implementation method of the present invention; Figure 3 is an example of the steps of the data management method for new energy power stations, which mainly involves file data, in the implementation method of the present invention; Figure 4 is an example of the functional principle of the data management subsystem in the implementation method of the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] This implementation method presents a technical solution for the data management of new energy power stations. The applicable architecture is shown in Figure 1. Based on the hierarchical architecture from the new energy power station to the regional centralized control zone I or II, then to the regional centralized control zone III, and finally to the data management subsystem, real-time data messages are sent to the data management subsystem in a change + periodic manner to improve the real-time performance of measurement data management and minimize maintenance response delays.

[0020] Referring to Figure 2, the method includes: uploading data from the new energy power station to regional control zone I or II; the data from the new energy power station includes real-time measurement data; after receiving the real-time measurement data from the new energy power station, regional control zone I or II synchronizes this real-time measurement data to the database of regional control zone I or II, and determines whether there are any changes in the data of the measuring points in this real-time measurement data, and sends the changed data to the message bus in the form of real-time data messages, and then forwards it to regional control zone III through a forward isolation device, and then sends it to the data management subsystem in the form of real-time data messages; the database of regional control zone I or II synchronizes its stored real-time measurement data to the database of regional control zone III through the forward isolation device according to a first set period, and the database of regional control zone III synchronizes its stored real-time measurement data to the data management subsystem according to a second set period.

[0021] Therefore, based on the hierarchical architecture of new energy power plants, from regional control zone I or II, then to regional control zone III, and finally to the data management subsystem, the system not only synchronizes real-time measurement data collected from new energy power plants in regional control zone I or II to regional control zone III through periodic database synchronization, and then uses regional control zone III as an intermediary to periodically synchronize to the data management subsystem, ensuring the comprehensiveness of measurement data updates, but also allows regional control zone I or II to filter out data that has changed and send it to the data management subsystem via regional control zone III as real-time data messages. In other words, the changed portion of the measurement data is sent up in real time. This improves transmission speed by reducing the amount of data transmitted, and avoids the time and potential slow transmission speed caused by processing measurement data into other forms, thereby comprehensively improving the real-time performance of measurement data management and preventing delays in operation and maintenance response.

[0022] Real-time measurement data mainly includes remote signaling and telemetry data and remote pulse data of new energy power stations connected to the regional centralized control system, such as wind turbine wind speed and active power. In this embodiment, the new energy power station level is the data source, sending the data to the regional centralized control zone I or II. The data received by the new energy power station in the regional centralized control zone I or II is synchronized to the regional centralized control zone III through a forward isolation device. Then, the data is sent to the data management subsystem by the regional centralized control zone III.

[0023] In a specific embodiment, the steps of the above-mentioned method for managing real-time measurement data (which may be referred to as measurement data or station-end measurement data) of new energy power stations mainly involve the following steps: 1) New energy power stations of different business types (such as wind farms, photovoltaic power stations, booster stations, etc.) realize the management of real-time measurement data such as SCADA within the station through the edge gateway, and then transmit the data through the IEC. 1) The data is sent to the regional control zones I and II via protocol 104; 2) After receiving the station measurement data, the front-end service of the regional control zones I and II first performs the data writing operation to the real-time database (i.e., the database of the regional control zone I or II), then determines whether the measurement data has changed, and sends the changed measurement data to the message bus such as Kafka according to a certain format; 3) The regional control zones I and II forward the real-time database and message bus data to the regional control zone III through the forward isolation device; 4) The regional control zone III sends real-time data messages to the message bus of the data management subsystem in a change + periodic manner; 5) After receiving the real-time measurement data, the data management subsystem stores it in the time-series database (i.e., the database of the data management subsystem) according to the dimensions of region, plant, equipment, etc.

[0024] Furthermore, in this embodiment, the data for the new energy power station also includes file data; in fact, the file data mainly includes wind turbine vibration monitoring files (CMS), protection device fault recording files (FRS), and power prediction files (PPS).

[0025] Based on this, referring to Figure 3, the data management method in this embodiment further includes: different types of file data are sent to regional control zones I and II respectively in a manner corresponding to the file type; the file data in regional control zones I and II are forwarded to regional control zone III in the form of files through a forward isolation device according to the set directory hierarchy; regional control zone III uses SFTP service to periodically pull different types of file data from the data management subsystem and store them in the file database corresponding to the data management subsystem; the set directory hierarchy includes stations, categories, subcategories and files, with stations having the highest hierarchy order, and categories, subcategories and files having progressively lower hierarchy order; higher-order levels contain lower-order levels.

[0026] This design, through a standardized directory hierarchy, forwards file data from Regional Control Zones I and II to Regional Control Zone III, making the transmission of file data clearly hierarchical. This facilitates the classification, storage, and hierarchical management of Regional Control Zone III and the data management subsystem. Especially in scenarios with large data volumes, such as new energy power plants, it can avoid the accumulation of massive amounts of heterogeneous data in the regional control system, thereby facilitating subsequent data scheduling and analysis.

[0027] In this embodiment, the directory hierarchy also includes dates, with dates ranking below the station level but above the file level. Of course, in other embodiments, if the file name already includes date information, or if it's unnecessary to display date information during transmission, the directory hierarchy may not include dates. In a preferred embodiment, files in Area Control Zone I or II are forwarded to Area Control Zone III via a forward isolation device according to the directory hierarchy: station / category / date / subcategory / file (e.g., wind power station / PPS / 20250514 / CDQ / DPDFDC_CDQ_20250514_0000.WPD).

[0028] Specifically, in this embodiment, different types of files are sent to the regional control zones I and II in a manner corresponding to their file types, including: for wind turbine vibration monitoring files, an SFTP service is built on the vibration monitoring system, and the files are retrieved periodically by the regional control zones I and II after being proxied by the edge gateway at the wind farm; for power prediction files sent by photovoltaic and wind farms, the IEC102 protocol is used to send the files to the regional control zones I and II respectively through the edge gateways at the wind farm and photovoltaic farms; for protection device fault recording files, an SFTP service is built by the protection information substation, and the files are retrieved by the regional control zones I and II after receiving the message, through the edge gateway at the booster station.

[0029] Different types of new energy power plants submit different types of documents. Wind power plants mainly submit CMS and PPS documents, photovoltaic power plants mainly submit PPS documents, and booster stations mainly submit FRS documents. In a specific embodiment, the steps of the above-mentioned method for managing new energy power station data, which mainly involves file data (which can be referred to as files), include: a) CMS files are periodically retrieved by regional control zones I and II after an SFTP service is established at the vibration monitoring system workstation and proxied by the edge gateway; PPS files are uploaded to regional control zones I and II via the edge gateway through the IEC102 protocol; FRS files are retrieved by the regional control zone after receiving messages and an SFTP service is established at the information protection substation and proxied by the edge gateway; b) Files in regional control zones I and II are forwarded to regional control zone III according to the directory hierarchy of power station / major category / date / minor category / file through a forward isolation device; c) Regional control zone III provides an SFTP service, and the data management subsystem periodically retrieves different types of files and stores them in a distributed file system (i.e., the file database corresponding to the data management subsystem), and maintains the relationship between files and business data in the file database.

[0030] In this embodiment, the data management subsystem is located in the regional centralized control zone III, as shown in Figure 4. It receives real-time measurement data and file data from various regional centralized control systems and, in conjunction with information from each site, including point tables and ledgers, processes the real-time measurement data and file data for database storage. This data management subsystem in this embodiment possesses functions such as file management, data management, data analysis, point table management, access control, and ledger management. It also provides a common interface for other business systems to access the measurement data and file data stored in the subsystem's database, thus fulfilling the function of a data foundation. This effectively enables the aggregation, storage, and management of full data from multiple regional new energy power stations, providing a data foundation for new energy power station analysis, operation and maintenance, and early warning services.

[0031] This embodiment provides a technical solution for a data management system for new energy power stations, including separate management modules for regional centralized control zone I or II, new energy power stations, and regional centralized control zone III. The management modules for regional centralized control zone I or II and the new energy power station management modules are used together to upload data from the new energy power stations to regional centralized control zone I or II. The data from the new energy power stations includes real-time measurement data. The management module for regional centralized control zone I or II is also used to synchronize the real-time measurement data to the database of regional centralized control zone I or II after receiving it, and to determine whether the real-time measurement data contains... When data changes at the measurement point, the changed data is sent to the message bus as a real-time data message, and then forwarded to the regional control zone III via a forward isolation device. The management module of the regional control zone III is also used to send that data to the data management subsystem as a real-time data message. The management module of the regional control zone I or II is also used to synchronize the real-time measurement data from the database of the regional control zone I or II to the database of the regional control zone III via a forward isolation device according to a first set period. The management module of the regional control zone III is also used to control the database of the regional control zone III to synchronize the real-time measurement data to the data management subsystem according to a second set period.

[0032] The aforementioned system, based on a hierarchical architecture from the new energy power plant to regional control zone I or II, then to regional control zone III, and finally to the data management subsystem, not only synchronizes real-time measurement data collected from new energy power plants in regional control zone I or II to regional control zone III through periodic database synchronization, and then periodically synchronizes it to the data management subsystem via regional control zone III, ensuring the comprehensiveness of measurement data updates, but also allows regional control zone I or II to filter out changed data and send it to the data management subsystem via regional control zone III as real-time data messages. In other words, only the changed portion of the measurement data is sent up in real time. This improves transmission speed by reducing the amount of data transmitted and by minimizing the time and potential slowdowns caused by processing measurement data into other forms, thereby comprehensively improving the real-time performance of measurement data management and avoiding maintenance response delays.

[0033] Real-time measurement data mainly includes remote signaling and telemetry data and remote pulse data of new energy power stations connected to the regional centralized control system, such as wind turbine wind speed and active power. In this embodiment, the new energy power station level is the data source, sending the data to the regional centralized control zone I or II. The data received by the new energy power station in the regional centralized control zone I or II is synchronized to the regional centralized control zone III through a forward isolation device. Then, the data is sent to the data management subsystem by the regional centralized control zone III.

[0034] In a specific embodiment, the working steps of the above-mentioned new energy power station data management system, which mainly involves real-time measurement data (which may be referred to as measurement data or station-end measurement data), include: 1) New energy power stations of different business types (such as wind farms, photovoltaic power stations, booster stations, etc.) realize the real-time measurement data such as SCADA within the station through the edge gateway, and then transmit the data through the IEC. 1) The data is sent to the regional control zones I and II via protocol 104; 2) After receiving the station measurement data, the front-end service of the regional control zones I and II first performs the data writing operation to the real-time database (i.e., the database of the regional control zone I or II), then determines whether the measurement data has changed, and sends the changed measurement data to the message bus such as Kafka according to a certain format; 3) The regional control zones I and II forward the real-time database and message bus data to the regional control zone III through the forward isolation device; 4) The regional control zone III sends real-time data messages to the message bus of the data management subsystem in a change + periodic manner; 5) After receiving the real-time measurement data, the data management subsystem stores it in the time-series database (i.e., the database of the data management subsystem) according to the dimensions of region, plant, equipment, etc.

[0035] Furthermore, in this embodiment, the data for the new energy power station also includes file data; in fact, the file data mainly includes wind turbine vibration monitoring files (CMS), protection device fault recording files (FRS), and power prediction files (PPS).

[0036] The management module for new energy power stations is also used to send different types of file data to regional control zones I and II in a manner corresponding to the file type. The management modules of regional control zones I and II are also used to forward the file data of regional control zones I and II to regional control zone III in the form of files through a forward isolation device according to the set directory hierarchy. The set directory hierarchy includes stations, categories, subcategories, and files, with stations having the highest hierarchy order, followed by categories, subcategories, and files in descending order. Higher-order levels contain lower-order levels. The management module of regional control zone III is also used to periodically pull different types of file data from the data management subsystem through the SFTP service and store them in the corresponding file database of the data management subsystem.

[0037] This design, through a standardized directory hierarchy, forwards file data from Regional Control Zones I and II to Regional Control Zone III, making the transmission of file data clearly hierarchical. This facilitates the classification, storage, and hierarchical management of Regional Control Zone III and the data management subsystem. Especially in scenarios with large data volumes, such as new energy power plants, it can avoid the accumulation of massive amounts of heterogeneous data in the regional control system, thereby facilitating subsequent data scheduling and analysis.

[0038] In this embodiment, the directory hierarchy also includes dates, with dates ranking below the station level but above the file level. Of course, in other embodiments, if the file name already includes date information, or if it's unnecessary to display date information during transmission, the directory hierarchy may not include dates. In a preferred embodiment, files in Area Control Zone I or II are forwarded to Area Control Zone III via a forward isolation device according to the directory hierarchy: station / category / date / subcategory / file (e.g., wind power station / PPS / 20250514 / CDQ / DPDFDC_CDQ_20250514_0000.WPD).

[0039] Specifically, in this embodiment, different types of files are sent to the regional control zones I and II in a manner corresponding to their file types, including: for wind turbine vibration monitoring files, an SFTP service is built on the vibration monitoring system, and the files are retrieved periodically by the regional control zones I and II after being proxied by the edge gateway at the wind farm; for power prediction files sent by photovoltaic and wind farms, the IEC102 protocol is used to send the files to the regional control zones I and II respectively through the edge gateways at the wind farm and photovoltaic farms; for protection device fault recording files, an SFTP service is built by the protection information substation, and the files are retrieved by the regional control zones I and II after receiving the message, through the edge gateway at the booster station.

[0040] Different types of new energy power plants submit different types of documents. Wind power plants mainly submit CMS and PPS documents, photovoltaic power plants mainly submit PPS documents, and booster stations mainly submit FRS documents. In a specific embodiment, the working steps of the above-mentioned new energy power station data management system, which mainly involves file data (which can be referred to as files), include: a) CMS files are periodically pulled by regional control zones I and II after an SFTP service is built on the vibration monitoring system workstation and proxied by the edge gateway; PPS files are sent to regional control zones I and II via the edge gateway through the IEC102 protocol; FRS files are pulled by the regional control zone after receiving the message and an SFTP service is built on the information protection substation and proxied by the edge gateway; b) Files in regional control zones I and II are forwarded to regional control zone III according to the directory hierarchy of power station / major category / date / minor category / file through a forward isolation device; c) Regional control zone III provides SFTP service, and the data management subsystem periodically pulls different types of files and stores them in the distributed file system (i.e., the file database corresponding to the data management subsystem), and maintains the relationship between files and business data in the file database.

[0041] In this embodiment, the data management subsystem is also part of the new energy power station data management system. Specifically located in the regional centralized control area III, it receives real-time measurement data and file data from various regional centralized control systems. Combining this with information from each power station, including point tables and ledgers, it processes the real-time measurement data and file data for database storage.
