基于LabVIEW风力发电系统中风场的模拟

摘要

In order to better monitor the performance of the wind power generation system,as the key link in wind power generation simulation system,it is necessary to study the wind field model.The wind speed mathematical model is composed of the basic wind,a gust of wind,the gradient wind and the random wind,and simple mathematical formula is used by each part,and then the mathematical model of each part and the whole combination wind speed are simulated in LabVIEW language.It is verified that the method can provide a good foundation for the establishment of laboratory wind power simulation system and can better reflect the natural wind speed situation.%为了更好地对风力发电系统性能进行监测,风场作为风力发电模拟系统中的关键环节,有必要对其模型进行研究.采用由基本风、阵风、渐变风和随机风4部分组合的风速数学模型,且每部分都用简单的数学公式建模,再利用LabVIEW语言对每部分及整个组合风速的数学模型进行仿真.经验证,该方法能够为实验室风力发电模拟系统的建立提供良好的基础,可以较好地反映自然风速的情况.
