摘要

由于配电系统中的大多数负载是感性的，因此通过电容器的应用进行功率因数校正是自然的选择。然而，电容器的安装会产生额外的问题，因为谐波污染和自然共振。为了避免这些问题，本文提出了一种新的电力电容器抗谐振有源系统。提出的有源系统由功率因数电容器串联的电力电子电流变换器组成。这将确保电力电容器具有低谐波含量，避免谐波谐振或失真公用电压造成的损坏。为了证明该系统的有效性，给出了一些结果。

An anti-resonance active method for a power factor correction capacitive system

Since most loads in electrical distribution systems are inductive, power factor correction through the application of capacitors is the natural choice. However, the capacitor installation can create additional problems, because of harmonic pollution and natural resonance. To avoid these problems, this paper proposes a new anti-resonance active system for power capacitors. The proposed active system is composed of a power electronics current converter connected in series with the power factor capacitors. This will ensure that the power capacitors have low harmonic content, avoiding the damage caused by harmonic resonance or distorted utility voltage. Some results are presented in order to show the effectiveness of the proposed system.
