Through theoretic reckoning and simulating analyzing , several control strategies for shunt apf were compared and chose ip - iq arithmetic of the instantaneous reactive power theory control strategy as the right scheme to produce the instructing current . based on it , some new control arithmetic was subjoined to suppress the resonance in system and balance the dc side capacitor voltage . two topologies of main circuit were compared and chose the three - phase voltage - source converter with a split - capacitor as its main circuit structure 通过理论计算和仿真分析,比较了并联型apf的几种控制策略的优点和缺点,从中选择瞬时无功理论控制策略i _ p - i _ q计算方式为指令电流产生的算法,并在此基础上增加了抑制系统谐振和平衡直流侧电容电压的控制;比较了并联型apf主电路的两种常见形式,从中选择了三相电压型变流器的主电路形式;算出适合该apf的直流侧电容和出线电感的参数;设计出能有效消除apf产生的高次谐波的高通滤波器。
