中文摘要：

针对微网中的谐波问题,对多台有源滤波器（APF）的并联运行治理微网谐波进行了研究,在比较并研究了均流策略和各种并联策略后,提出了一种新的微网中APF并联方法和控制策略,研究了均流策略和并联实现方法。通过仿真验证了该方法的可行性和可靠性,说明该方法具有很好的动态性能和补偿效果。

英文摘要：

Aiming to solve the harmonic problems in Micro grid, the parallel operation of multiple APFs（active power filter） was studied. After compared and studied many strategies of current sharing and parallel operation, a new kind of parallel operation and contral stratege was proposed, and studied the implementation of the stratege. Finally, the simulation results verify the feasibility and reliability of the method, and show that the method has a good dynamic performance and compensation effect.
