风力机模拟系统使在实验室内开展风力发电技术的各项研究成为可能。分析了风力机特性，建立了风力机模型。通过对异步电机间接磁场定向矢量控制技术的研究，考虑到安装速度传感器具有诸多缺陷，提出基于模型参考自适应( MRAS)转速辨识理论的无速度传感器异步电机的风力机模拟控制方法，并且考虑到转子时间常数对矢量控制系统的影响，采用同时辨识电机转速和转子时间常数，使系统辨识转速同时，对电机参数变化具有较强的鲁棒性。利用MATLAB/SIMULINK搭建了基于无速度传感器异步电机的风力机模拟系统，通过对风力机特性，最大风能捕获和电机参数对矢量控制系统影响的仿真，证明了系统的可行性。

Wind turbine simulator( WTS) is an important device for developing wind energy conversion systems. Its use makes the e-valuation and improvement of wind power generation technology in laboratory possible. A wind turbine model is built up through the research of the wind turbine characteristics. Then the indirect flux field oriented vector control strategy is studied. Because many de-fects exist in fixing speed sensor on induction motor, a speed-sensorless vector control scheme based on model reference adaptive system( MRAS) for wind turbine simulation of induction motor is proposed. Taking into account the impact of the rotor time constant on the vector control system, the paper simultaneously adopts identification rotor speed and time constant. The speed can be esti-mated accurately by the system, which system shows strong robustness to variation of motor parameters. At last, In MATLAB envi-ronment, the simulation system for wind turbine emulation based on speed-senseless control strategy of induction motor is designed. Through the simulation of wind turbine properties, maximal wind energy capture and the influence of parameter variation on vector control system,in indicates that the system is feasible.
