The embodiment of the invention provides a parameter management system 100 of a wind generating set. Fig. 1 discloses a schematic block diagram of a parameter management system 100 of a wind park according to an embodiment of the invention. As shown in fig. 1, a parameter management system 100 of a wind generating set according to an embodiment of the present invention includes a main control system 10 of the wind generating set and a remote server 20 connected to the main control system 10. The remote server 20 includes a parameter database 21, the parameter database 21 may store parameter data and parameter version information, and the remote server 20 may obtain a configuration parameter file to be delivered from the parameter database 21 and encrypt the configuration parameter file to be delivered. The main control system 10 includes a PLC (Programmable Logic Controller) platform, and the PLC platform 11 may receive the encrypted configuration parameter file, analyze the encrypted configuration parameter file, and perform data loading.
The PLC platform 11 of the master control system 10 may perform parameter assignment on the operation variables of the wind turbine generator system by using the analyzed configuration parameter file after the data is successfully loaded.

And obtaining parameter values, and assigning the operation variables of the wind generating set by using the obtained parameter values to execute corresponding process control.
In the run phase, determine if there is a SCADA update command from the SCADA system? If an SCADA updating command exists, the configuration parameter file in the PLC platform is replaced, the process returns to the step of acquiring the parameter file again, and the configuration parameter file is read again and data loading is carried out. If the SCADA updating command does not exist, the configuration parameter file in the PLC platform is not replaced, at the moment, the process is continued according to the parameter information in the configuration parameter file read previously, the parameters are grouped correspondingly based on different subsystems in the wind generating set, and the parameters can be displayed on the HMI.
The user can modify the parameters of the wind generating set by logging in the HMI, and the parameters of the wind generating set are modified. If the modification fails due to, for example, a user authority problem or a parameter modification value exceeding a predetermined range, the diagnostic system may be adjusted to determine the cause of the modification failure, and a corresponding fault log may be generated and displayed on the HMI. If the modification is successful, the modification process of the parameters can be recorded through the event records, and meanwhile, the process returns to the step of acquiring the parameter values, and the modified parameters are used for carrying out corresponding process control.
