单相并联型有源电力滤波器主电路参数耦合关系研究

摘要：

单相并联型有源电力滤波器(SAPF)主电路参数之间存在一定的耦合关系， 这对各参数值的合理选择有较大的影响。 通过分析现有单/三相SAPF主电路交流侧电感以及直流侧电压、 电容值等参数的计算方法， 得到了具体的单相SAPF电路参数解析表达式。 针对所得表达式各变量之间的耦合关系， 在MATLAB中进行建模优化分析， 得出一套完整的参数设计方案。 保证在特定负载下补偿后谐波含量低于2%的综合优化目标。 仿真和实验过程验证了所选参数的正确性。

Abstract： There is a certain coupling relationship among the main circuit parameters of a single-phase shunt active power filter (SAPF), which has a great influence on the reasonable selection of various parameter values. By analyzing the calculation methods of the inductance of alternating current (AC) side and the voltage and capacitance values of direct current (DC) side in the existing single/three-phase SAPF main circuit, a specific single-phase SAPF circuit parameter analytical expression was obtained. Aiming at the coupling relationship among the variables in the resulting expression, the model was optimized and analyzed in MATLAB, and a complete set of parameters design scheme was obtained, which ensure the comprehensive optimization target of the post-harmonic content below 2% is compensated under a specific load. The simulation and experimental procedures verify the correctness of the selected parameters.
