组合风速模型研究与模拟

Research and Simulation of Combined Wind Speed Model

主要介绍了随机变量可以分解成的4个分量,以及这4个分量在变量发生随机变化时的主要作用。并将这一原理移用到风速标量中(暂时忽略风向矢量),使1个随机的风速模型分解为基本风、随机风、阵风、渐变风4个分量,代表了风速模型的稳定性、随机性、突变性和渐变性,并以表达式定义了各个分量,且以1个简单的示例模拟了一段短暂时间的风速模型。

This paper mainly introduces the four components that a random variable can be decomposed into,and the main functions of these four components when the variable changes randomly.This principle is applied to the scalar of wind speed(temporarily ignoring the wind direction vector),so that a random wind speed model is decomposed into four components:basic wind,random wind,gust and gradual wind,representing the stability,randomness,abrupt change and gradual change of the wind speed model.Each component is defined by an expression,and a simple example is used to simulate the wind speed model for a short period of time.
