[0027] An embodiment of the present invention provides a parameter management system 100 for a wind turbine generator set. Figure 1 A schematic block diagram of a parameter management system 100 for a wind turbine generator set according to an embodiment of the present invention is disclosed. Figure 1 As shown, a parameter management system 100 for a wind turbine generator set according to one embodiment of the present invention includes a main control system 10 of the wind turbine generator set and a remote server 20 connected to the main control system 10. The remote server 20 includes a parameter database 21, which can store parameter data and parameter version information. The remote server 20 can obtain configuration parameter files to be distributed from the parameter database 21 and encrypt the configuration parameter files to be distributed. The main control system 10 includes a PLC (Programmable Logic Controller) platform. The PLC platform 11 can receive the encrypted configuration parameter files, parse them, and load data from them.

[0028] After the data is loaded successfully, the PLC platform 11 of the main control system 10 can use the parsed configuration parameter file to assign parameters to the operating variables of the wind turbine generator set. The PLC platform 11 can also group parameters accordingly for different subsystems of the wind turbine generator set.

[0029] In one embodiment, the remote server 20 may transmit the encrypted configuration parameter file directly to the PLC platform 11 of the main control system 10 .

[0030] The parameter management system 100 of the embodiment of the present invention establishes a unified parameter database 21, supports a unified data source, and has accurate and unique parameters, thereby enabling effective control and management of parameter data of wind turbines.

[0031] Furthermore, the parameter management system 100 of the embodiment of the present invention can encrypt the configuration parameter file to be sent by the wind turbine generator set, and can further parse the encrypted configuration parameter file accordingly in the main control system 10 of the wind turbine generator set, thereby ensuring the security of the data during the transmission process.

[0032] In some embodiments, the main control system 10 includes a user interface 12 connected to the PLC platform 11. The user interface 12 can be used to display information for the user to view and promptly understand parameter changes. In one embodiment, the user interface 12 can include, for example, a human-machine interface (HMI).

[0033] When data loading is abnormal, the data loading abnormality can be displayed on the user interface 12. In some embodiments, the PLC platform 11 includes a diagnostic system. When data loading is abnormal, the diagnostic system in the PLC platform 11 can generate a corresponding fault log and display the corresponding fault log on the user interface 12.

[0034] The user can also perform corresponding operations through the user interface 12 at the site of the wind turbine generator set, such as logging in, modifying the parameters of the wind turbine generator set, etc. The user interface 12 can be used to receive the parameter modifications made by the user to the wind turbine generator set.

[0035] In one embodiment, the user interface 12 can provide multiple ways to modify parameters. The PLC platform 11 can determine the user's authority based on the user's login information on the user interface 12, and can provide corresponding modification methods on the user interface 12 based on the user's authority. The multiple modification methods may include, for example, temporary modification and long-term modification. Temporary modification refers to modifying only the current actual operating value of the wind turbine generator set without changing the parameter value in the configuration parameter file. In this case, the actual operating value of the wind turbine generator set will change, but the parameter value in the configuration parameter file will not change. Therefore, the parameter value will still maintain the parameter value in the configuration parameter file when the wind turbine generator set is powered on next time. Long-term modification refers to modifying not only the current actual operating value of the wind turbine generator set but also the parameter value in the configuration parameter file. In this case, the actual operating value of the wind turbine generator set and the parameter value in the configuration parameter file will both change. Therefore, the parameter value will be saved and will still maintain this value when the wind turbine generator set is powered on next time.

[0036] After a parameter modification is successful, the user interface 12 can also save the parameter modification record, thereby facilitating the traceability of the parameter modification process. If the parameter modification is unsuccessful, an abnormality can be displayed on the user interface 12. For example, if a parameter modification is unsuccessful, the diagnostic system of the PLC platform 11 can generate a corresponding fault log and display the corresponding fault log on the user interface 12.

[0037] The parameter management system 100 of the embodiment of the present invention may further include a SCADA (Supervisory Control And Data Acquisition) system 30 connected to the main control system 10. The user interface 12 may transmit parameter modification records to the SCADA system 30, thereby enabling the SCADA system 30 to back up the parameters of the wind turbine generator set and facilitate the SCADA system 30 to trace the parameter modification process.

[0038] In another embodiment, the remote server 20 can send the encrypted configuration parameter file to the SCADA system 30, which then distributes the encrypted configuration parameter file to the PLC platform 11 of the master control system 10 of each wind turbine. For example, each wind turbine in a wind farm can update its own configuration parameter file based on an update command from the SCADA system 30. Thus, the SCADA system 30 can be used to send and update configuration parameter files for multiple wind turbines in the wind farm.

[0039] In some embodiments, the SCADA system 30 is also connected to the remote server 20. The SCADA system 30 can obtain the parameter modification record from the main control system, and based on the parameter modification record, transmit the modified parameters back to the remote server 20. After the modified parameters are verified in the remote server 20, the modified parameters can be recorded in the parameter database 21.

[0040] Continue to refer to Figure 1 As shown, in some embodiments, the parameter management system 100 of the present invention may further include a development and design platform 40 connected to the remote server 20. Development and testing can be performed on the development and design platform 40 based on the parameters in the parameter database 21. After the test is completed, the tested parameters are returned and updated to the parameter database 21. This allows for consistency in wind turbine parameters from development to application.

[0041] Figure 2 The following is a flow chart showing the internal processing of the main control system 10 of a wind turbine generator set after the configuration parameter file is given to the PLC platform of the main control system according to an embodiment of the present invention. Figure 2 As shown in the figure, during the initialization phase, the parameter system in the main control system calls the parameter configuration file from the file system and loads the configuration file data. If the data loading is abnormal and the parameters do not meet the requirements, the diagnostic system is called to determine the fault type, generate a corresponding fault log, and display it on the HMI. If the data loading is successful, the process continues and the parameters are successfully read. The parameter version is obtained and the parameter version information is simultaneously entered into the online software package version management for unified management of parameter versions. Furthermore, the parameter values ​​are obtained and used to assign the wind turbine operating variables to perform the corresponding process control.

[0042] During the run phase, is there a SCADA update command from the SCADA system? If so, it indicates that the configuration parameter file in the PLC platform has been replaced. The process then returns to the parameter file acquisition step, rereading the configuration parameter file and loading the data. If there is no SCADA update command, it indicates that the configuration parameter file in the PLC platform has not been replaced. At this point, the process continues according to the parameter information in the previously read configuration parameter file, grouping the parameters according to the different subsystems of the wind turbine and displaying them on the HMI.

[0043] Users can log in to the HMI and modify the parameters of the wind turbine generator set. If the modification fails due to, for example, user permission issues or the modified parameter value being outside the specified range, the diagnostic system can be used to determine the cause of the modification failure, generate a corresponding fault log, and display it on the HMI. If the modification is successful, the parameter modification process is recorded in the event log. At the same time, the process returns to the step of obtaining the parameter value, and the modified parameters are used for corresponding process control.

[0044] Figure 3 The following is a flow chart showing the parameter transmission of a wind turbine generator set according to an embodiment of the present invention. Figure 3 As shown, the parameter feedback of a wind turbine generator set according to one embodiment of the present invention can be performed from step S11 to step S17. In step S11, for example, the SCADA system can be triggered regularly or manually to start the parameter feedback mechanism. In step S12, the main control system of the wind turbine generator set can encrypt the saved parameter modification record and send it to the SCADA system in the form of a file. In step S13, after the SCADA system obtains the encrypted parameter file of the wind turbine generator set, it can send the encrypted parameter file to a designated remote server. In step S14, the remote server can parse the encrypted parameter file. In step S15, the parameter modification in the parsed parameter file is confirmed. In step S16, after the modified parameters are verified on site, if it is confirmed that the wind turbine generator set operates well using the modified parameters, the modified parameters can be written into a unified parameter database. In step S17, if the operating effect of the modified parameters cannot be confirmed temporarily, further verification of the parameter values ​​is continued.

[0045] The parameter management system of a wind turbine generator set in one or more embodiments of the present invention can achieve consistency in the parameters of the wind turbine generator set from development to application, and ensure accurate feedback iteration after parameter modification, so as to ensure that the actual application effect of the wind turbine generator set is controllable and the parameters after verification can be accurately fed back.

[0046] The parameter management system of the wind turbine generator set according to one or more embodiments of the present invention uses a parameter database with a unified data source, which can ensure the consistency of design parameters and operation parameters.

[0047] The parameter management system of a wind turbine generator set according to one or more embodiments of the present invention can encrypt data during the process of parameter issuance and transmission, support encryption and decryption of configuration parameter files, and ensure parameter security.

[0048] Furthermore, the parameter management system for wind turbines according to one or more embodiments of the present invention supports parameter modification and recording at the wind turbine end during the application of wind farm data, facilitating traceability management.

[0049] The parameter management system of the wind turbine generator set in one or more embodiments of the present invention is at the wind turbine end. After parameter verification, the actually used parameters can be sent back to a unified parameter database through a timed feedback mechanism, and recorded and improved in the unified parameter database, so that the wind turbine generator set parameters can be truly applied to the actual iterative development process, which is conducive to the optimization and iteration of the wind turbine generator set parameters.

[0050] An embodiment of the present invention further provides a wind farm. The wind farm may include multiple wind turbines and a parameter management system for the wind turbines as described in the above embodiments. The parameter management system may manage the parameters of the multiple wind turbines.

This article uses specific examples to illustrate the parameter management system of the wind turbine generator set and the wind farm of the embodiment of the present invention. The description of the above embodiment is only used to help understand the core idea of ​​the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the spirit and principles of the present invention, the present invention can also be improved and modified. These improvements and modifications should also fall within the scope of protection of the claims attached to the present invention.
