摘要
本文通过对充电设施工作产生的谐波分析及仿真,得出采用基于SPWM脉宽调制闭环指令电流的跟踪控制方法,采用闭环能量回馈方案的装置对充电设施谐波补偿的高精度控制进行验证,有效检测抵消充电设施引起的谐波,实现对充电设施谐波污染的治理,提升电能质量。
The tracking control method based on SPWM pulse width modulation closed-loop command current is obtained by harmonic analysis and simulation of charging facilities. The closed-loop energy feedback scheme is used to verify the high- precision control of the harmonic compensation of the charging facilities, which effectively detects and counteracts the harmonics caused by the charging facilities and realizes the control of the harmonic pollution of the charging facilities and improves the power quality.
