室内风速模拟的一种数值方法

A numerical method for the simulation of wind speed in laboratory

在风力发电技术的研究中,进行室内试验是最有效率的方法,这样就必须模拟实际风场的风,而自然风具有不确定性,难于精准的构造模型.运用非平稳随机过程的方法,建立基于观测数据的非平稳随机过程的数学模型,运用这个模型和康平风场实际观测数据,进行了风速样本模拟.结果表明,采用本方法只需利用少量的风速观测数据就可以很好的模拟自然风.

In studying the technology of wind energy,the most effective way is to conduct experiments in the laboratory. Thus the actual wind field should be simulated which is indefinite and is difficult to set up a model for simulation. In this paper, a mathematical model of non-stationary random process had been built that was based on the data of a non-stationary random process. This model and the data of monitoring wind were used to simulate the actual wind field in Kangping. It is shown that the actual wind can be simulated well only with a small part of monitoring wind data.
