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 通過(guò)理論計(jì)算和仿真分析,比較了并聯(lián)型apf的幾種控制策略的優(yōu)點(diǎn)和缺點(diǎn),從中選擇瞬時(shí)無(wú)功理論控制策略i _ p - i _ q計(jì)算方式為指令電流產(chǎn)生的算法,并在此基礎(chǔ)上增加了抑制系統(tǒng)諧振和平衡直流側(cè)電容電壓的控制;比較了并聯(lián)型apf主電路的兩種常見(jiàn)形式,從中選擇了三相電壓型變流器的主電路形式;算出適合該apf的直流側(cè)電容和出線電感的參數(shù);設(shè)計(jì)出能有效消除apf產(chǎn)生的高次諧波的高通濾波器。
