摘　　要：针对混合型有源电力滤波器(HAPF)中的无源滤波器(PF)会与线路电感发生并联谐振的问题,提出一种补偿非线性负载谐波和抑制无功补偿装置和线路电感谐振的控制策略。与检测负载侧电流相比,检测网侧电流具有控制目标闭环和节省硬件采样环节的优点。最后通过仿真和实验验证了所提控制策略的有效性。Aiming at the problem of parallel resonance between passive filter(PF)and line inductance in hybrid active power filter(HAPF),a control strategy for compensating nonlinear load harmonics and suppressing reactive com pensation device and line inductance resonance is proposed.Compared with detecting load current,detecting power side current has the advantages of controlling target closed loop and saving hardware sampling.Finally,simulation and experiment verify the effectiveness of the proposed control strategy.
