摘要
针对并联型有源电力滤波器(PAPF)直接启动产生很大的冲击电流的现象,详细分析了该现象产生的原因,提出了一种PAPF分段启动控制策略,该控制策略分为串联电阻不控整流阶段、恒流启动阶段和电压软启阶段,各阶段平稳过渡,无过电压和冲击电流现象。研制了一台50 kVA的PAPF实验样机,实验结果证明了该控制策略的有效性。
Aiming at the phenomenon that huge inrush current is generated when parralel active power filter(PAPF)directety start,the segmented startup control method for PAPF is proposed by after the cause of the phenomenon is analyzed in detail.The control method is formed in three stages:uncontrolled rectifier stage with series resistance,constant current start-up stage and voltage soft start stage.There is no overvohage and inrush current during the smooth transition.An experimental prototype with 50 kVA capacity is developed.Experimental resuhs demonstrate the effective-ness of the control strategy.
