Embodiment Construction

[0025] To meet the real-time requirements of wind turbine monitoring, use symmetric encryption technology and verification technology to encrypt the transmitted data at the data sending end, and insert verification information indicating the validity of the data, and decrypt it at the receiving end and follow the Validation rules are checked for validity.

[0026] The monitoring of wind turbines has high real-time performance, requiring less time-consuming encryption and decryption process. Both the sending end and the receiving end of the wind turbine monitoring data are the same system products in the station, which ensures the availability of the key. Therefore, the symmetric encryption method is very suitable for the data transmission of the wind turbine. Combined with the data verification technology, a A method to solve the data transmission security of the wind farm monitoring system.

[0027] Design a unique 32-byte encryption factor as a key to encode the transmitted...

Abstract

The invention discloses a safe data transmission method for a central monitoring system of a wind turbine generator, which comprises the following steps of: encrypting transmitted data at a data sending end by using a symmetric encryption technology and a verification technology, setting verification information representing the validity of the data, decrypting at a receiving end, and checking thevalidity according to a verification rule. The specific technical measures of the method are as follows: designing a unique 32-byte encryption factor as a secret key, encoding transmitted data, calculating the length of a data stream at a data sending end, putting the data stream into the head of the data stream, and adding verification data generated according to a verification rule into the tail of the data stream; performing reverse encoding by using the same 32-byte key at a data receiving end, and analyzing the data; extracting data information from the data stream by using the actuallyreceived data length; and obtaining verification information according to the verification rule, and comparing the verification information with the verification information at the tail of the received data stream.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and relates to a data security transmission method of a central monitoring system of a wind turbine. Background technique [0002] As a kind of power production equipment, the wind turbine generator set has a very important operation data security. If the monitoring data of wind turbines is not encrypted and verified during transmission to local workstations or remote workstations, it is easy to be eavesdropped, analyzed or even tampered with when the system is attacked. If the eavesdropping is successful, it will cause information leakage. If it succeeds, it will cause potential safety hazards in system operation. At present, there are special encryption and decryption equipment, but the use of special encryption and decryption equipment will greatly increase the cost, and increase the difficulty of system installation and debugging, and these equipment generally have restrictions...
