摘　　要：分析了有源电力滤波器(active power filter,简称APF)的系统结构和工作原理,采用基于瞬时无功功率理论的ip-iq检测算法,计算出APF的谐波指令电流,并选择电流跟踪控制方式之一的滞环比较方式。采用PSCAD/EMTDC软件为工具,对APF进行了建模及仿真分析;并在此基础上,设计了基于DSP的控制系统,仿真和试验结果证明了控制策略的有效性。The system structure and working principle of APF were analyzed,harmonic order current was obtained based on the instantaneous reactive power theory of ip-iq detecting algorithm,then hysteresis comparator method was applied to follow tracks of harmonic current.Modeling and simulating were carried out under the environment of PSCAD/EMTDC.Finally,control system was designed based on DSP.The experimental results proved the effectiveness of control strategy.
