摘要
有源电力滤波器的控制系统及选用的控制算法是决定滤波效果的关键。近年来,随着电子技术的飞速发展及各种数字处理芯片性能的显著提高,有源电力滤波器的控制系统逐步由模拟控制系统向数字模拟混合控制系统和数字控制系统转化。基于DSP和CPLD的全数字控制系统设计出的高性能动态补偿装置——三相四线制有源电力滤波器(APF),可对大小与频率都变化的谐波和无功进行快速补偿,能够满足有源电力滤波器对控制系统的要求。
The control system of active power filter and the selected control algorithm are the key issues that will decide the filtration effect. Recently,with the fast development of electronic technology and dramatic improvement in the performance of various digital processing chips the control system of active power filter gradually changes from analog control system to digital control system and digitalanalog hybrid control system. The high-performance dynamic compensation device based on DSP and CPLD is capable of making rapid compensation to the harmonic wave and reactive power whose size and frequency are always on the change to meet the demand of active power filter to the control system.
