A method of establishing a predictive response system based on wind turbine load database

Abstract

The invention discloses a method for establishing a predicated response system based on a wind turbine generator load database. The method comprises the following steps: (1) establishing a load database; (2) exploring a processing scheme of the load database, wherein the processing scheme comprises a first choice scheme and a secondary choice scheme, and the first choice scheme is a regression analysis method; and (3) analyzing and comparing a processing result of the first choice scheme and the processing result of the secondary choice scheme to establish a proper load prediction response system. The advantages and the disadvantages of the prior art are combined to quickly establish the proper prediction response system, the established prediction response system can solve a problem that a load adaptability analysis or anticipation method is low in response speed on model selection requirements, the quick response of the model selection and the micro-location selection of the wind turbine generator is realized through a quick "wind resource-load-strength-adaptability judgment" response mode of the predicated response system, the load situation of each point location can be quickly predicted to be obtained so as to basically realize the "refinement" of the load adaptability analysis.

Description

technical field [0001] The invention relates to the field of wind turbine load applicability analysis, in particular to a method for establishing a prediction response system based on a wind turbine load database. Background technique [0002] Usually wind turbines are designed according to various external conditions specified by international standards GL or IEC, but the external conditions of actual wind farms are often quite different from those specified in the standards, and these external conditions (especially wind conditions) The difference between wind turbines and wind turbines mainly affects the load safety of wind turbines, so at present, wind farm projects need to carefully evaluate their external conditions when selecting wind turbines in the early stage. In a narrow sense, the load safety evaluation of pre-selected wind turbines under actual wind conditions is called load applicability evaluation. Specifically, the load applicability assessment of wind turbi...

Problems solved by technology

However, this method also has its inherent disadvantages: due to the wide range of wind turbine operating wind speeds and the complex combination of actual working conditions, this direct simulation method is very complex and time-consuming, and is suitable for the design stage, but it is used in the load adaptability assessment there are certain limitations

[0010] It can be seen that the above-mentioned existing methods for calculating or predicting the load of wind turbines under the actual wind condition parameters obviously still have various inconveniences and defects in use, and further improvement is urgently needed
