Abstract: The Active Power Filter(APF) is an effective technique of eliminating harmonics and reactive power compensation.APF includes two parts of the topology configuration and its control system,and the key problem of active filtering technique is its control system,which determines the performance and compensating effect of APF.An all-digital control system of the hybrid active power filter based on dual DSPs is introduced.The novel control strategy,hardware structure and software modules are described in detail.A 20 KVA prototype is developed,and the test results show that it is good in performances and in harmonics elimination,reactive power compensation.In addition,this facility is in favor of application due to its good cost performance.

摘要: 有源电力滤波器是近年发展起来的治理谐波和无功补偿的一种有效的技术。有源电力滤波器主要包括拓扑结构和控制系统两部分,而控制系统是APF的核心部分,决定了APF的性能指标和补偿效果。介绍了一种全数字控制双DSP结构混合有源电力滤波器控制系统,详细分析了全数字控制系统的新型控制算法、硬件电路和软件流程。搭建了一个20 KVA的样机进行了实验研究,实验结果表明该装置滤波和无功补偿效果较好,这种HAPF的性能价格比较高,具有良好的工程推广应用价值。
