摘要

提出了一种新的单相并联有源电力线调节器(aplc)在零平均功耗下运行的控制方法。正弦源电流与源电压同相的幅值可由瞬时负载功率的平均值确定。然后，通过从负载电流中减去源电流获得分流APLC的命令电流。既不需要庞大的过滤器，也不需要耗时的计算。并联电源补偿器提供负载电流的所有谐波，电源只提供基波分量。在样机上的实验结果验证了该方案的可行性。

A new control method for single-phase active power line conditioners

A new control method for single-phase shunt active power line conditioners (APLCs) operated under zero average power consumption is proposed in this paper. The amplitude of the sinusoidal source current which is in-phase with the source voltage can be determined from the average value of the instantaneous load power. Then the command current for the shunt APLC is obtained by subtracting the source current from the load current. Neither bulky filter nor time-consuming computation is required. The shunt power compensator supplies all the harmonics of the load current and the source only supplies the fundamental component. Experimental results on a prototype verify the feasibility of the presented scheme.
