| 摘 要： | 在海上风力发电系统运行过程中,通过对低海况下塔架结构的应力水平监测,获得一系列的结构应力幅与风速风向的关系及自重对塔架结构应力的影响关系。基于灰色预测模型——GM（1,1）模型,本文对塔架结构的高风况下应力水平进行预测,计算了塔架结构的承载能力,为今后塔架的设计研究提供了基本的试验数据。

| Abstract: | Through monitoring the stress level of offshore wind turbine generator system under low oceanic condition in practical working process,a series of data between stress amplitude and wind speed as well as wind direction are attained,and the influence of deadweight on the stress is also obtained.The collected data are used to predict the stress level of the wind turbine tower under high oceanic condition based on grey predicting model——GM（1,1） model and to calculate the tower＇s bearing capacity in this paper.This provides the experimental data for tower design henceforth. |

| Keywords: | grey prediction wind turbine tower stress level GM(1 1) model |
