Iqmethod ) 、 the harmonic current detection based on synchronous reference frame transformation have been analyzed iq法)、基于同步坐標變換的無功與諧波電流的檢測方法。
So there are good prospects for alternating current excitation generators . in this thesis, the operation principle of aceg and the excitation control strategy based on dynamical synchronous reference frame are analyzed, the simulation models of the generator and excitation controller are established based on the saber simulator . according to the requirement of aceg, the converter should have regeneration capability, and the input and output currents of converter should be sinusoidal 由于交流勵磁發(fā)電機既可能運行于勵磁系統(tǒng)向電機轉子方輸入電功率,也可能運行于勵磁系統(tǒng)將轉子方輸出的電功率回饋給電網,根據交流勵磁發(fā)電機系統(tǒng)對勵磁變頻器功率雙向流動及變頻器輸入和輸出電流諧波含量少、諧波幅值小的要求,本文提出采用輸入和輸出性能優(yōu)良的矩陣式交-交變頻器作為勵磁電源。
