摘要

描述了锂电池能量回收系统的设计方案，并对系统的进网电流谐波抑制能力进行了深入的理论分析和仿真研究，总结了系统的谐波阻抗特性。在此基础上，探讨了通过优化控制策略进一步抑制电网电压畸变引起的低次谐波的方法，同时分析了基于电网电压定向的PI控制策略的局限性。以一台3.7 kVA能够稳定运行的样机实现了设计方案，并通过一系列实验结果验证了所述方法的正确性和有效性。

Abstract

The design scheme of a grid-connected system is described for the lithium battery power recovery. The harmonic current suppression capability of the proposed system is analyzed in detail. Based on the derived system harmonic impedance， a method to optimize the harmonic suppression by adjusting the control scheme is discussed， as well as the limitation of regular controller. Simulation and experimental results with a 3.7 kVA prototype machine validate the proposed method.
