摘要: |
并联型有源电力滤波器(SAPF)的直流侧电容电压直接影响谐波补偿性能。合理的电容电压设定值既可以保证补偿效果,又可以降低直流侧电容的耐压值选取要求。针对三相并联型有源电力滤波器直流侧电容电压优化设计这一问题,通过对典型的负载条件下谐波电流进行分析,推导出在完全补偿谐波电流的情况下变流器的输出电压矢量值。基于空间矢量脉冲宽度调制方式(SVPWM),分析了直流侧电容电压选取方法。仿真结果验证了该方法的有效性。 |

Abstract: |
The DC-side capacitor voltage of shunt active power filter (SAPF) has direct influence on the performance of the harmonic compensation. A reasonable setting value of the capacitor voltage can guarantee the compensation effect and reduce the voltage value of the DC-side capacitor. Aiming at the problem of design and optimization of DC-side capacitor voltage, through the analysis of the current under the typical load condition, the output voltage vector of the converter is derived when the harmonic current is fully compensated. Based on the space vector pulse width modulation (SVPWM), the selection method of DC-side capacitor voltage is analyzed. Simulation results confirm the validity of the method.
