摘要
为了实现风电场风力发电机组载荷的快速评估,对机组载荷预测进行了研究,提出了采用多元线性回归方法进行载荷预测建模,通过训练已有的数据库,得到准确的载荷预测模型。将预测结果与实际定场址计算结果进行了对比。结果表明:主要分量的极限载荷预测误差基本在3%以内,疲劳载荷误差在2%以内,能大幅度提高载荷评估效率,提高投标响应竞争力。
In order to assess wind turbine load rapidly,load prediction was studied.A multielement linear regression method was proposed for load prediction modeling.An accurate load prediction model was obtained through load data training.Results from comparison with prediction data with actual load showed that the ultimate load prediction error of the main component was within 3%,and the fatigue load error was within 2%,which could greatly improve the efficiency of load assessment.
