摘要:
      在d-q-0坐标系下建立了三相四线直流电容中分结构的单调谐式混合有源电力滤波器(HAPF)的数学模型。通过此数学模型,对含中线电感与不含中线电感的单调谐式HAPF无源部分的滤波特性进行了分析和讨论。根据HAPF有源部分的容量分析并结合其无源部分的滤波特性,优化了一般负载谐波电流情况下的三相四线单调谐式HAPF的结构,并给出了其直流侧最小电压等级的表达式,通过减小HAPF有源部分容量达到了降低HAPF成本的目的。最后,通过仿真验证了最小电压等级理论的正确性及此优化结构的有效性。
Abstract:
      This paper establishes a mathematical model of three-phase four-wire center-split single-turned hybrid active power filters(HAPF)in d-q-0coordinate. Based on this mathematical model,the filtering characteristics of the passive part of the single-tuned HAPF with and without neutral inductor are analyzed and discussed. According to the HAPF active part capacity analysis and the filtering characteristics of its passive part,the structure of the three-phase four-wire single-turned HAPF can be optimized and its minimum DC-link voltage expression can be deduced based on the general harmonic current contents of the loading. Therefore,the cost of the HAPF can be lowered by reducing its active part capacity. Finally,the correctness of the minimum DC-link voltage theory and the effectiveness of this optimized structure are verified by simulation.
