Abstract

The invention relates to a method for evaluating dynamic aerodynamic characteristics of a wind turbine, particularly provides a method and a system for evaluating the dynamic aerodynamic characteristics of the wind turbine, and aims to solve the problem of low accuracy of an existing method for evaluating the aerodynamic characteristics of a blade airfoil. In order to achieve the purpose, the method for evaluating the dynamic aerodynamic characteristics of the wind turbine comprises the steps of dividing the dynamic stall process of an airfoil into an attached flow process, a trailing edge separation process and a dynamic vortex process; determining corresponding coefficients of the airfoil under attached flow, trailing edge separation and dynamic vortex; and determining dynamic aerodynamic characteristic information of the wind turbine based on the corresponding coefficients, and evaluating the dynamic aerodynamic characteristics of the wind turbine based on the information.

Description

technical field [0001] The invention relates to the field of wind power generation, and specifically provides an evaluation method and system for the dynamic aerodynamic characteristics of a wind turbine. Background technique [0002] In a horizontal axis wind turbine, the blade is one of its key components, and the aerodynamic characteristics of the blade airfoil play a decisive role in the operation and life of the entire wind turbine. Therefore, how to accurately evaluate the aerodynamic characteristics of the blade airfoil is of great significance. [0003] The evaluation of the aerodynamic characteristics of the existing blade airfoil is mainly based on the original B-L model and the model modified by scholars, but the accuracy of these two models is not high, and the evaluation quality of the corresponding aerodynamic characteristics is difficult to meet the actual needs . [0004] Therefore, there is a need in the art for an evaluation scheme for the dynamic aerodyn...
