Problems solved by technology

However, the principle of using the screen coordinate capture software to set the working conditions is to capture the key operations of the mouse or keyboard, based on the value of the screen coordinate points, there must be a clear sequence of execution, so the setting process is cumbersome, inefficient, and universal. low reliability
Therefore, in general, there is currently no mature and general quick setting method for load calculation setting

Embodiment Construction

[0025] Such as figure 1 As shown, the implementation steps of the method for fully automatic generation of working conditions used in wind turbine load calculation in this embodiment are as follows:

[0026] 1) According to the input wind resource data and the basic parameters of the fan, calculate the intermediate parameters required for the generation of the specified basic Bladed wind model. The intermediate parameters include fixed value parameters and threshold parameters. The threshold parameter is the upper boundary value used to set the threshold, The lower boundary value or both upper and lower boundary values, the threshold parameters correspond to the variables that need to be modified in the basic Bladed model file; the initialization settings specify the wind model parameters of the basic Bladed wind model, and save the intermediate parameters and wind model parameters for subsequent calls.

[0027] In this embodiment, the wind resource data in step 1) includes ai...

Abstract

The invention discloses a full-automatic working condition generation method and device used for wind turbine generator load calculation. The method includes the following steps that firstly, a middle parameter and a wind model parameter are calculated; secondly, a basic Bladed model file is selected, and a constant value parameter in the wind model parameter and the middle parameter is substituted; thirdly, according to a variable in the basic Bladed model file, a series of working condition variable value sets are generated; fourthly, new Bladed model file data are generated for each working condition variable value set with the basic Bladed model file as a template; fifthly, the data are saved according to specified routes and working condition file names. The device comprises a middle parameter and wind model parameter generation module, a model file import module, a working condition variable value set circulating generation module, a variable searching and modifying module and a working condition file saving module. By means of the method and device, the working condition setting process is simplified, working conditions are generated full automatically, operation is easy and quick, reliability is good, and accuracy is high.

Description

technical field [0001] The invention relates to the technical field of load calculation of wind turbines, in particular to a method and device for fully automatic generation of working conditions for load calculation of wind turbines. Background technique [0002] At present, the main tool for wind turbine load calculation in the wind power industry is the Bladed software of GH Company. Load calculation using Bladed needs to be set according to the working conditions specified in the IEC or GL standards. Since there are many factors to be considered, there are as many as 3,000 working conditions for a complete set of load calculations. The traditional way is to use the Batch that comes with Bladed to set the working conditions, which is time-consuming and laborious, and it is easy to make mistakes during the setting process due to the large number of parameters. It is understood that in the prior art, there is a method of using the screen coordinate capture software to real...
