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
