摘要: 在分析有源电力滤波器拓扑结构的基础上,研究了直流母线电压和进线电抗器的选择对有源电力滤波器无功补偿效果的影响,提出了基于电压平均值的电抗器改进选择策略。实验结果表明,直流母线电压为720 V、APF侧电抗器值为1.5 mH时,电网电流畸变率小,系统动态性能良好。Abstract: The paper studied influence of DC bus voltage and line reactors on reactive compensation effect of active power filter based on analysis of its topology, and proposed improved selection strategy of reactor based on average voltage. The experimental results show that grid current distortion is small, and system dynamic performance is good under the condition of DC bus voltage of 720 V and APF side reactor of 1.5 mH.
