摘要
指出工厂企业具有低压配电系统普遍具有的特点,其电能质量最突出和普遍的问题是电网谐波。阐述了谐波的危害并对其进行了分析,指出主要的谐波源为各种电机拖动中的电力电子装置,可以通过装设无源滤波器和有源滤波器进行治理。提出了一种模块化配置方案,易于扩容和安装,且具有机柜式有源滤波器所不具备的优点。
The paper describes the factory power supply system simply and the most of important question of the power quality is harmonic in system.It analyzed that the harmonic sources were all kinds of power electronic equipments from field measurement.To suppress the harmonic,reducing the harmonic sources or compensating system for current are necessary.The passive filter and the active power filter are the effective techniques for harmonic suppression.The Active Power Filter has multifold configuration scenarios.The paper provides a modular configuration,which can be installed and expanded easily and has a rack-mountable active filter has advantages not available.
