基于数据库的风电场疲劳载荷适应性平台

Wind Farm Fatigue Load Site Suitability Tool Based on Database

提高风电场疲劳安全性评估的效率,是载荷工程师亟待解决的技术问题。由于陆上风电场及海上风电场的多变性,风电场不同机位点的风资源条件有所不同,导致每一个机位点的疲劳载荷不一样。风场适应性软件开发平台结合通过大量的数据分析,进行载荷敏感性分析,推导出各种风条件对载荷的影响,从而建立疲劳载荷数据库。通过输入各个机位点的风条件,检索数据库并进行插值计算后直接提取各机位点的疲劳载荷,从而直观并极大地提高风电场疲劳安全性评估效率。

Improving the efficiency of wind farm fatigue safety assessment is a technical problem to be solved urgently by load engineer.Due to the variability of onshore and offshore wind farms,some wind farms have different wind resource conditions at different sites,resulting in different fatigue loads at each location.The wind farm site suitability tool combines a large amount of data analysis for load sensitivity analysis,calculates the influence of wind conditions on load,finds out relevant laws,and establishes a fatigue load database.By entering the wind conditions of each wind turbine location,searching the database and performing interpolation calculations,the fatigue load of each wind turbine location can be directly extracted,there by greatly improving the efficiency of wind farm fatigue safety assessment.
