风力发电机组极限外推参数估计对比研究

Comparison of Parameter Estimation Methods for Extreme Load Extrapolation of Wind Turbine

本文采用全局最大值法提取风力发电机组的载荷极值,选择三参数威布尔分布预测长期极限载荷,对比分析4种不同参数估计方法(线性矩法、相关系数法、极大似然法、矩估计法)对外推结果的影响。

In this paper,the global maximum method is used to extract the maximum load from each simulation of wind turbine,and the three parameter Weibull distribution is used to predict long-term extreme load.The extrapolation results of four parameter estimation methods including L-moment estimation,correlation coefficient estimation,maximum likelihood estimation and moment estimation are compared.
