摘　　要：并联型有源电力滤波器广泛应用于终端配电所及终端负荷的谐波与无功补偿。通过分析电网中的典型谐波源,说明整流器直流侧为电感滤波时,特性类似谐波电流源,为电容滤波时,特性类似谐波电压源。在分析并联型有源电力滤波器工作原理的基础上,研究并联型有源电力滤波器对不同谐波源的补偿特性。通过研究得出结论:并联型有源电力滤波器适用于补偿电流源型谐波源非线性负载,不适用于补偿电压源型谐波源非线性负载,并且会产生谐波电流放大效应。同时给出了抑制谐波电流放大效应的措施。Parallel active power filter is widely used for harmonic and reactive power compensation in terminal distribution station and terminal load.By analyzing typical harmonic source in the power grid,it is shown that when the DC side of the rectifier is the inductive filter,its characteristic is similar to harmonic current source,while it is the capacitive filter,its characteristic is similar to harmonic voltage source.Based on the analysis of the working principle of parallel active power filter,the compensation characteristics of parallel active power filter for different harmonic sources were studied.The conclusion drawn through research is that parallel active power filter is suitable for compensating nonlinear load of current source type harmonic source,but not suitable for compensating nonlinear load of voltage source type harmonic source,and the latter will produce harmonic current amplification effect.In addition,the measure was provided to suppress the amplification effect of harmonic current.
