有源电力滤波器谐波补偿方法的研究及仿真

Research and simulation of harmonic compensation method for active power filter

应用TI公司的TMS320F2812DSP作为核心处理器搭建了一台100kV·A三相三线制并联型有源电力滤波器(Active power filter,APF)的实验样机,并进行了相关实验.首先介绍了样机的总体结构,然后对谐波检测各部分的硬件设计进行了阐述,对主电路开关器件和直流电容的参数进行了选择,设计了死区和驱动保护电路,最后对有源电力滤波器实验样机的实验结果进行了分析.实验结果证明,所设计的样机对各次谐波均有良好的补偿效果,电流谐波含量降到了13%~15%.

The experimental prototype of a 100 kV·A three-phase three wire parallel active power filter（Active power filter,APF）was built by using TMS320 F2812 DSP of TI Company as the core processor,and the related experiments were carried out.First,the overall structure of the prototype is introduced.Then the hardware design of each part of the harmonic detection is described.The parameters of the main circuit switch device and the DC capacitance are selected;the dead zone and the driving protection circuit are designed.Finally,the experimental results of the APF experimental prototype are analyzed.The experimental results show that the designed prototype has good compensation effect for all harmonics,and the current harmonic content is reduced to 13%~15%.
