风力发电机组不同于火电等传统发电机组的最大之处
在于其原动机功率的本质不可控，这是由风速的易变性和不
可控性造成的。风速状况对风力发电系统的性能有着重要的
影响，也使得风速模型成为风力发电系统仿真模型的重要部
分。该文针对风速随机变化的特性，在风速统计特性研究的
基础上，用自回归滑动平均(ARMA)方法建立了具有一定
功率谱密度特性的风速模型。对该模型所模拟的风速序列进
行了分析和验证，并与现有仿真程序中风速模型的结果进行
了对比，结果表明该文提出的ARMA模型能

Abstract-The mobile radio channel can be simulated as a
complex-valued random process with a time-varying variance.
This paper describes an implementation of that process using
a real-time Digital Signal Processing (DSP) technique. The simulato
