大功率有源滤波器直流侧电容设计与电压控制

DC Side Capacitor's Design and Voltage Control in High-capacity Active Power Filter

针对现阶段高压大容量有源滤波(APF)系统直流侧电容的设计问题,根据实际装置的研制经验,系统阐述了大功率并联混合型有源滤波器直流侧电容的设计过程,并提出了一种简单有效的直流侧电压稳定控制方法。由于目前国内大功率有源滤波系统的工程应用实例很少,因此提出的设计方法与工程经验还可用于对其它有源滤波系统的研究,并起到一定的应用指导借鉴作用。

With the design problem of DC side capacitance in high-capacity active power fiher,the paper expatiates a whole set of design methods based on an actual active power filter device, and then proposes a simple control method for DC side voltage with good effect.For China there is few applications of high-capacity active power filter till now,the given parameter design method and engineering experience are useful for applications and research of other active power filter.
