Abstract The arising of wind turbine simulator(WTS) makes the evaluation and improvement of wind power generation technology in laboratory possible. In this paper, by analyzing the aerodynamic characteristic of wind turbines, it unveils that the conventional static simulation method of WTS will change the frequency model of real wind turbine, and can not reproduce its transient behavior. Although the appearance of dynamic simulation method could overcome these problems, the common used method which is realized by derivative calculation of rotor speed will greatly deteriorate the stability of WTS, and increase the design strength and difficulty because low-pass filters should be elaborately designed. Therefore, another dynamic simulation method which thoroughly eliminates the usage of derivative operator and considerately improves the performance of WTS is addressed, whereas the complexity of WTS remains unchanging. The operational principle and feasibility of the two methods are detailed discussed. Finally, simulation and experiment are carried out.

Key words： Wind power generation WTS dynamic simulation derivative operator stability
