电力电子技术快速发展,各种电力电子装置广泛应用,使得谐波问题越来越严重。针对某电渣炉的单相供电方式和谐波的多样性,本文对国内外抑制谐波的有关资料概述,对电渣炉单相供电方式进行谐波分析,提出采用把具有良好谐波抑制的混合有源电力滤波器HAPF与无源滤波器相结合的综合谐波抑制策略。
The rapid development of power electronics technology, a variety of power electronic devices are widely used, making the harmonic problem more and more serious. Aiming at the single-phase power supply mode and the diversity of harmonics in a electroslag furnace, this paper summarizes the relevant literature about the suppression of harmonics at home and abroad, carries on the harmonic analysis on the single-phase power supply mode of the electroslag furnace, proposes to adopt the harmonic suppression Hybrid Active Power Filter HAPF and Passive Filter Combined Harmonic Suppression Strategy.
