有源电力滤波器的设计

Design for Active Power Filter

随着电力电子装置的广泛应用,大量的谐波和无功电流注入电网,引起污染,造成电能质量问题日益严重,有源电力滤波器是补偿电力系统谐波及无功功率的重要装置,其控制的实时性和准确性是实现有效补偿的一个关键。以三相系统中的电网电流为研究对象,介绍了有源电力滤波器的系统结构和工作原理,讨论了主要元件参数的设计和计算。

With the wide application of power electronic equipments in power system, more harmonic and reactive current are poured into the power system, which cause power pollution and make the power quality problem increasingly serious. Active power filter is an important equipment to Compensate harmonic and reactive current in power system and the key of the effective compensation lies in the real - time and accurate control. Focusing on the current of three - phases power supply, the system configuration and operation principle of APF are introduced. The design and computing of the main components are discussed.
