Tunable Filter Development and Application Research
摘要
The proportion of new energy in current power systems is increasing, and the use of adjustable filters has significant importance for improving grid harmonic problems, maintaining grid stability, performing reactive power compensation, and effectively enhancing grid operation performance and reliability. This article explores the principles and characteristics of different harmonic mitigation methods in passive and active filtering, and proposes using adjustable components to replace fixed capacitors or fixed inductors to constitute adjustable filters specifically for passive LC filters. It also introduces the principles and characteristics of several adjustable capacitors and adjustable reactors.
