为了实现对电力有源滤波器(APF)直流侧电压的有效控制,本文通过三段式软启动建压措施克服装置投入瞬间的冲击电流,并从主电路的拓扑结构找到直流侧电压的取值方法,提出了基于电压偏差平方值 PI 控制的策略降低了装置的空载电流,改善了补偿效果.样机的实际运行工况验证了系统控制方案的可行性,对电力有源滤波器的研制以及工程应用有一定的指导意义.

In order to achieve effective control of DC side voltage for active power filters, the input instantaneous shock current from SAPF can be overcome through a three–stage soft start-up measure and the selection method for taking DC side voltage ideal value is obtained based on the main circuit topology. The deviation square value PI control strategy is found to have reduced no-load current and improved system compensation effect. Actual operating conditions of samples verify the feasibility of the system control scheme, which is of guiding significance to the development and engineering application of active power filters.
