摘　　要：分析了风力机的静态和动态转矩特性,确定了风机模拟器的主要模拟对象,建立了风力机模型;制定了简单有效的转矩控制方案,搭建了基于DSP的直流电机风力机模拟硬件平台,应用LABWINDOWS开发了上位机界面。该风力机模拟系统不仅可以模拟不同风速时风力机的静态转矩特性,也可以模拟风塔效应和剪切效应所造成的转矩脉动,满足变速恒频风力发电系统研发的需要,可方便用于实验室条件下风电技术的研究。In this paper, the wind turbine characteristics are analyzed, and a wind turbine model is proposed, a simple and effective emulation scheme is built up based on torque control. A wind turbine emulation platform based on DSP and DC motor is set up, the supervisor system is designed and implemented using LABWINDOWS. The emulation system is used in a grid-connected variable speed constant frequency wind power system, it can emulate the static and dynamic behavior of a wind turbine, which satisfies the need of the system research, and makes the research on the wind power technology become very convenient in the laboratory conditions..
