  1. Thus, it is difficult to find the voltage reference for the harmonic analysis. since acem are always operated near to the synchronous speed, the frequency of the excited voltage is very low, even to zero. therefore, this is the power harmonic suppression study of a complicated power supply system, in which the about harmonic general theories and methods are all inapplicable

    現代交流勵磁電機( acem )採用電力電子流器作為勵磁,其勵磁電壓諧波含量豐富,難于獲得諧波分析所需的電壓基準,同時交流勵磁電機經常工作在同步轉附近,致使勵磁電壓頻率低甚至為直流,通常的諧波檢測方法和理論都法適用,因而這是一種目前尚未深入探討過的復雜供用電系統電力諧波抑制問題的研究。
