| 中文摘要: |
| 通过对瞬时电压与瞬时电流乘积的周期复位积分得到基波有功电流,进而用负载电流与基波有功电流相减计算出无功电流与谐波电流之和。相对传统检测法,省去了复杂的谐波电流计算。由于这种方法应用于APF中存在难以实现直流侧平衡控制问题,提出一种新方法,即将直流侧PI调节器输出三等分后再与各相基波有功电流相加作为有功电流的参考信号,这样能实现在提供抵消谐波和无功所需的功率的同时,系统各相均能提供一定的有功电流来维持直流侧电压稳定。仿真和实验结果证明了该方法的正确性。 |

| This method obtained the fundamental active current through single-cycle reset integration of the products of the transient voltage and the instantaneous current and then load current subtracting the fundamental active current got the sum of the reactive current and the harmonic current.Because of when this method was applied to APF,it was difficult to realize DC side balancing control,a new method was proposed:the trisection of the output of PI regulator plus to each phase fundamental active current was us... |
