摘 要：介绍了将矢量控制技术应用于轴向磁场磁通切换永磁(AFFSPM)风力发电机，研究了AFFSPM电机在直驱风电系统中的动态转速响应。采用转速-转矩曲线模拟风力机特性，以一台三相12/10极AFFSPM发电机作为控制对象，搭建了基于DSP的AFFSPM直驱风电系统整流侧实验平台。根据叶尖速比控制给出转速指令，应用磁场定向矢量控制策略对AFFSPM风力发电机进行了转速跟踪实验。实验结果表明，直驱风电环境下的AFFSPM发电机在采用磁场定向矢量控制时具有快速、准确的转速响应。

Abstract: Introduction was made to the application of vector control technology in axial field flux-switching permanent magnetic wind power generator (AFFSPM). Study was made on dynamic rotation speed response of AFFSPM generator in direct-drive wind power system. The rotation speed-torque curve was adopted to simulate wind generator characteristics. With a three-phase 12/10-pole AFFSPM generator as control object, the experimental platform of AFFSPM direct-drive wind power system at rectifier side was built based on DSP. According to blade-tip-speed ratio control, rotation speed instructions were given and the field oriented vector control strategy was used to carry out rotation speed tracking experiment for AFFSPM wind generator. Experimental results show that in direct-drive wind power environment, the AFFSPM generator with field oriented vector control has swift and correct rotation speed response.
Key words: axial-field; flux-switching; direct-drive wind power generation; vector control
