摘　　要：首先分析了风力机和直流电动机输出特性的相似性,阐述了用直流电动机模拟风力机特性的可行性。针对传统的风力机特性模拟器只能实现稳态转矩模拟的缺点,该文提出了一种可以实现风力机动态转矩模拟的新方法,并在Matlab/Simulink环境下建立了风力机特性动态模拟器的仿真模型。仿真结果表明,该动态模拟器能够很好地实现风力机的动态和稳态特性模拟。Based on the analysis of the similarity between the mechanical characteristics of DC motor and wind turbine, the possibility of wind turbine simulator by using a DC motor was discussed. Contraposing the traditional wind turbine simulators capable of imitating steady-state torque only, this paper proposes a new dynamic simulator which can track the dynamic torque of the wind turbines. The simulation model of this dynamic simulator for wind turbines was built in the Matlab/Simulink. The simulation results indicated that the simulator can imitate both dynamic and steady-state characteristics of the wind turbine.
