摘要
文章利用拉伊达准则筛选异常点的方法,设计了一种三维风速仪风速数据质量控制软件,并进行了实际应用。结果表明:异常点可使风速极值统计结果明显偏大,但随着统计时距的延长,这种影响逐渐减小。文章设计的软件能够自动完成数据质量控制,可为科研、业务人员提供帮助。
This paper designs a software for quality control of 3D anemometer wind speed data by using the method of screening abnormal points with Pauta criterion,and it is applied in practice.The results show that the abnormal points make the statistical result of extreme wind speed significantly larger.With the prolongation of the statistical time interval,the influence decreases gradually.The software designed in this paper can automatically complete the data quality control,which can provide help for scientific research and operational staff.
