摘要
为减少电力系统中的谐波与无功功率污染问题,提高电能的有效利用率,设计了一种经济性的三相四开关并联型有源电力滤波器。阐述了三相四开关并联型有源电力滤波器主电路关键参数的计算方法,分析了有源电力滤波器的主电路拓扑结构、控制系统硬件原理及算法的软件实现流程。现场工程应用案例证明了该系统的可行性和有效性。
To reduce the harmonics and reactive power pollution and improve the effective utilization of ener- gy, a low-cost three-phase four-switch shunt active power filter was proposed. Key parameters calculation of three- phase four-switch shunt active power filter was presented. The topology structure of main circuit, the principles of the control system and the flow of the control software were described. The application in industrial site proves its feasibility and validity.
