电气化铁路APF的LCL滤波器的双环控制

Dual-loop of LCL-filter of Active Power Filter for Electrified Railway

针对电气化铁路谐波治理的APF的LCL输出滤波器进行分析,采用电容电流和电网电流的双环控制,达到滤除谐波净化电网的目的。对LCL滤波器的稳定性和动态性能进行了分析设计,满足实际需求,并进行了仿真验证。

To filter the harmonic caused by electrified railways,APF is applied to the railway power system.The analysis of the LCL output filter of APF is done,using capacitance current and grid current dual-loop control to filter out the harmonic and purify grid current.The stability and dynamic performance of LCL filter is also analyzed to design the filter to meet the actual demand.Moreover, simulation is done for verification.
