基于非平稳模型的15MW漂浮式风力机动力响应
The dynamic response of 15 MW floating wind turbine based on nonstationary model
摘要
Abstract
To investigate the combined effect of different turbulence intensity wind fields and yaw faults on the dynamic response of IEA 15 MW wind turbines,the empirical mode decomposition(EMD)method was used to decompose the wind speed at the hub,analyze the differences between traditional stationary and non-stationary models,and study the non-stationary dynamic response of wind turbine blade root flapping moment,platform pitch and pitch under different operating conditions.Research has shown that the time-varying average term obtained through EMD decomposition can better describe the pulsating trend of wind power response.The non-stationary model used in the article improves the accuracy of wind power response calculation under different operating conditions;The mean flapping moment of the blade root gradually decreases with the yaw angle,and due to the stability of steady-state wind,the mean flapping moment of the blade root decreases with the increase of turbulence intensity.And its extreme value decreases first and then increases under the combined effect of turbulent wind field and yaw fault,indicating that the combined effect of the two causes the wind turbine structure to exhibit more severe non-stationary dynamic response.The pitch and heave of the platform gradually decrease with the increase of yaw angle under steady-state wind conditions.Compared with the normal turbulent conditions under steady-state wind conditions,the proportion of pitch and heave decrease decreases.However,under extreme turbulent conditions,the mean pitch increases at a 15°yaw angle,and the extreme and mean pitch increase at a 15°yaw angle.This indicates that in the event of a unit yaw failure,turbulent wind can increase the platform's motion response.关键词
