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。%　　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 experi-ment 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.
