A Detecting Approach of Harmonic Currents Based on the Least Compensated Currents

本文提出一种基于补偿电流最小原理的谐波与无功电流检测方法,并在此基础上构成的APF加以实现。该检测方法不仅对周期变化的畸变电流有很好的补偿特性,而且对突变电流能快速跟踪,不仅适用于单相,而且适用于三相电路。理论分析和仿真结果证实了所提方案的正确性和可行性。

This paper proposes a new detecting approach of harmonic and reactive currents based on the least compensated currents, and obtains realization with active pewer filter. The proposed detecting approach not only can be good compensatory characteristic for aberrant currents of periodic change, but also can track rapidly for chopped currents. It can be the same with single-phase and three-phase circuits. The results of the theoretical analysis and computer simulation confirm the validity and feasibility of the proposed approach.
