摘　　要：提出一种新型小功率实验平台模拟兆瓦级风力机风轮特性的控制策略。通过对兆瓦级风机转矩特性等功率缩小和低转速特性的准确跟踪,实现风力机风轮静态特性的模拟。利用原动机侧变换器能够模拟兆瓦级风机缩比转矩特性,发电机侧变换器可准确跟踪风机低转速特性。分别针对风速和转速变化两种情况进行了分析,结果表明该方案能准确模拟兆瓦级风力机风轮静态运行特性。The MW wind turbine is today＇s mainstream.This paper presents a control strategy of new low power test platform to simulate the MW wind turbine blade characteristics.By reducing torque characteristics and accuratly track-ing low speed characteristics,the static characteristics of wind turbine simulation can been achieved.The prime move side converter is used to achieve simulating the torque characteristics of the MW wind turbine,generator-side convert-er is used to achieve the tracking features of the low speed characteristics of wind turbine.The experiment is done under two conditions of variable wind speed and variable motor velocity,the results show that the program can accurately simulate the operational characteristics of MW wind turbine.
