摘 要：介紹了將矢量控制技術應用于軸向磁場磁通切換永磁(AFFSPM)風力發(fā)電機，研究了AFFSPM電機在直驅風電系統(tǒng)中的動態(tài)轉速響應。采用轉速-轉矩曲線模擬風力機特性，以一臺三相12/10極AFFSPM發(fā)電機作為控制對象，搭建了基于DSP的AFFSPM直驅風電系統(tǒng)整流側實驗平臺。根據(jù)葉尖速比控制給出轉速指令，應用磁場定向矢量控制策略對AFFSPM風力發(fā)電機進行了轉速跟蹤實驗。實驗結果表明，直驅風電環(huán)境下的AFFSPM發(fā)電機在采用磁場定向矢量控制時具有快速、準確的轉速響應。

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
