基于DSP的并联有源电力滤波器数控系统

Shunt active power filter digital control system based on DSP

传统无源电力滤波器的设计方法过分依赖经验,优化能力弱。针对有源电力滤波器设计的难点,基于瞬时无功功率理论,开发了一种基于TMS320LF2407A的并联有源电力滤波器数字控制系统。介绍了有源滤波器的工作原理及系统结构,并详细论述了利用TMS320LF2407A芯片开发并联有源电力滤波器的设计方案,包括硬件和软件两部分。实验结果表明,所提出的设计方法正确有效,所开发的软件实用性强。

Beacuse the conventional approaches for passive power filters design depend on experiences too much and they are lack of ability for optimization and the difficulty of APF designing, a shunt active power filter（SAPF） digital control system based on TMS320LF2407A was adopted based on instantaneous reactive power theory. The working theory and the system structure of active power filter were introduced in the first. And the designing strategy of how to use TMS320LF2407A researching SAPF, including hardware and software,was discussed. The experiment indicate that this approach is correct and efficiency and the digital control system is worth to generalizing.
