根据虚拟试验对复杂风场环境的实际需要,提出了综合风场环境模型的概念。采用面向对象的建模方法建立了综合风场模型框架,对综合风场模型进行了顶层描述。通过静态模型和动态模型描述了虚拟试验综合风场的静态结构和动态行为。设计了通用的综合风场模型接口,使得该模型可以更好的应用到不同的虚拟试验平台中。设计了可扩展的基本风场模型库,保证了综合风场模型的可扩展性。针对基本风场中常见的大气紊流和微下击暴流,分别使用随机过程的方法以及涡环原理模型建立其数学模型,用于实时产生虚拟试验风场数据。最后介绍了该模型在虚拟试验中的一个应用实例,该实例表明,虚拟试验综合风场环境模型可以更好、更灵活的为虚拟试验提供支持。
According to the actual needs of virtual experiment for complex wind farm environment, the concept of integrated wind farm environment model is proposed. An object-oriented modeling method was used to establish a comprehensive wind farm model framework and a top-level description of the integrated wind farm model. The static structure and dynamic behavior of virtual test wind field are described by static model and dynamic model. A general integrated wind farm model interface is designed, which makes the model better applied to different virtual test platforms. A scalable base wind farm model library is designed to ensure the scalability of the integrated wind farm model. Aiming at the common atmospheric turbulence and micro-downburst in the common wind field, the mathematical models of the turbulence model and the stochastic process are respectively used to generate the data of the virtual experimental wind field in real time. Finally, an application example of the model in virtual experiment is presented. The example shows that the virtual experiment integrated wind field environment model can provide better and more flexible support for virtual experiments.
