Wind power plant information security system based on identity authentication and maintenance method

Abstract

The invention discloses a wind power plant information security system based on identity authentication and a maintenance method. The wind power plant information security system comprises a wind field maintenance control system and an authorization end, wherein the wind field maintenance control system distributes different types of maintenance information to the authorization end; a verification end used for reading the maintenance information stored in the authorization end and verifying the maintenance information; and a wind-driven generator controller connected to the verification end, and used for receiving the maintenance information read by the verification end after the verification end verifies the maintenance information, and executing corresponding operations according to different types of maintenance information. According to the invention, a unauthorized person can be prevented from logging in the system to operate the wind-driven generator, information and operation of logging in the system by maintainers can be recorded, and maintenance work of the wind-driven generator is facilitated.

Description

technical field [0001] The invention relates to a wind power plant, in particular to an identity authentication-based wind power plant information security system and maintenance method. Background technique [0002] At present, the tower tube door of domestic wind turbines is currently the key door lock for most wind turbines in China. Due to long-term exposure to the outside of the tower tube, it is easily corroded by rain or air. After a long time, the key cannot be used to open the door. Lock. Because the tower tube door lock is a keyed door lock, it is easy to be violently destroyed by criminals who enter the tower tube to steal wind turbine equipment. It is easy to cause damage and loss of unit components. And because there are many wind turbines in the wind farm, if all the wind turbines use the same key, the security will be reduced, or if the keys of each unit are not uniform, it is often easy to take the wrong key and affect the maintenance efficiency of the wind...

AI Technical Summary

Problems solved by technology

[0002] At present, the tower doors of domestic wind turbines are mostly keyed door locks. Due to long-term exposure to the outside of the tower, they are easily corroded by rain or air. After a long time, the key cannot be used to open the door. Lock

Since the tower door lock is a key door lock, it is easy to be violently destroyed by criminals who enter the tower to steal wind turbine equipment

Easy to cause damage and loss of unit components

And because there are many wind turbines in the wind farm, if all the wind turbines use the same key, the security will be reduced, or if the keys of each unit are not uniform, it is often easy to take the wrong key and affect the maintenance efficiency of the wind turbines

And at present, the maintenance personnel who enter the unit can only be recorded through the key record book of the maintenance personnel on duty in the wind farm, which is easy to miss and misremember
