摘　　要：分析了风力机的输出特性,建立了风力机模型,通过比较风力机和永磁同步电机(PMSM)特性,提出了基于PMSM风力机模拟的转矩-转速控制方案;对PMSM采用i_d=0的矢量控制方案,满足风力机转矩输出特性的模拟要求。该风力机模拟系统应用于离网型变速恒频永磁同步风力发电系统,实现了风力机在不同风速、全转速范围的风力机特性输出,满足了永磁同步风力发电系统进行最大功率追踪的需要。搭建了一套完整的风力发电模拟试验平台,验证了PMSM模拟风力机的可行性。The output characteristics of wind turbine （WT） and its mathematical model were analyzed and established. Based on these, the control method of wind turbine simulation （WTS） in accordance with torque-speed curve was proposed by comparing the characteristics of WT and PMSM. To satisfy the requirements of the torque characteristic of WT, the vector control strategy by i~ = 0 was adopted in it. This WTS was applied in variable speed constant frequency off-grid permanent magnet synchronous wind power system （WPS）. Its output characteristics in various speeds of wind and motor shaft could meet the requirements for maximum power point tracking （MPPT） for PMSG control. A platform for WPS was constructed to verify the feasibility of the proposed WTS control method.
