有限阻抗型混合有源电力滤波器的新检测方案
A NEW HARMONICS DETECTION DESIGNING FOR HYBRID ACTIVE POWER FILTER OF FINITE HARMONIC IMPEDANCE
摘要
Abstract
Applying feedforward control of harmonic voltage to hybrid active power filter of finite harmonic impedance can restrain line harmonic voltage. It is found that the higher voltage signal will reduce the extraction quality of harmonic current if current and voltage signals use the same d-q filter. In this paper, a LC filter inserted before d-q filter for voltage signal pre-process can attenuate the fundamental component of voltage signal effectively and change the harmonics slightly only. Analytic and experimental results show that the method can keep the extraction quality of harmonic current and meet the requirement of harmonics extraction of line voltage without increasing the system complexity.关键词
