摘　　要：介绍了一种新型的基于混合励磁同步发电机的直驱式风力发电系统。针对混合励磁直驱式风力发电系统的特点,提出了一种新的控制策略,实现了最大风能跟踪。在同步旋转坐标系建立了混合励磁同步发电机和三相并网逆变器的数学模型,通过控制混合励磁同步电机的励磁电流来稳定三相并网逆变器的直流母线电压,并通过控制混合励磁同步发电机的转速来实现最大风能跟踪。网侧变换器采用电网电压定向的矢量控制,实现了dq轴电流解耦控制。仿真结果表明:该控制策略使三相并网逆变器有良好的动、静态性能,且实现了风能的最大跟踪。A novel direct-drive type wind power generation system based on hybrid excitation machine was introduced.A new control strategy was proposed according to the characteristics of the wind power generation system based on hybrid excitation machine to achieve peak power point tracking.The mathematical model of the hybrid excitation machine and three-phase grid-connected inverters were established in the synchronous rotating coordinate.A control strategy which through the control of excitation current of hybrid ...
