Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0032] Such as figure 1 As shown, the load reduction method of the wind power generating set in this embodiment includes: S1. Obtaining the measurement data of the bolt connection position in the wind generating set; S2. Analyzing the measurement data through a large database, when the analysis result does not meet the preset trigger Conditions continue to run normally, and jump to step S3 when the analysis result meets the preset trigger condition; S3. Send a preset logic command to the wind turbine to achieve the purpose of reducing the load with the actual wind turbine.

[0033] In this embodiment, the bolt connection positions in step S1 include: the flange surface of the tower, the connection surface between the blade root flange and the pitch bearing, and ...

Abstract

The invention discloses a load reduction method and system for a wind power generating set. The method includes: S1. Obtaining measurement data of bolt connection positions in the wind power generating set; S2. Analyzing the measurement data through a large database. The preset trigger condition continues to run normally, and when the analysis result satisfies the preset trigger condition, it jumps to step S3; S3. Sends a preset logic command to the wind turbine to achieve the purpose of reducing the load with the actual wind turbine. The invention can predict the running state of the wind turbine in advance, predict in advance whether the wind turbine is experiencing a large load, and adjust the control strategy in advance to reduce or avoid the large load, realize the purpose of reducing the load of the wind turbine, and greatly improve the safety of the wind turbine or reduce the wind turbine. advantages such as cost.

Description

technical field [0001] The present invention relates to the technical field of control of wind power generators, in particular to a load reduction method and system for wind power generators. Background technique [0002] The load of the wind turbine is the input of the design of all components, and the size of the load directly determines the cost of the wind turbine. Therefore, within a reasonable range, it is very beneficial to the design of the fan to reduce the load as much as possible. At present, most of the load reduction methods are to reduce the load by detecting the change of wind speed and selecting different control parameters or strategies. Or according to the different states of the wind turbine, choose different control strategies and pitch rate to reduce the load. These load reduction methods are often effective when extreme events have occurred or are occurring, and have produced or are producing adverse effects on the unit. Moreover, the accuracy of inp...
