摘要
有源阻尼对谐振抑制作用机理是对谐振峰值附近的输出频率分量进行反馈控制。据此,根据各反馈位置的差异,分析有源阻尼技术应用于LCL滤波器不同反馈位置的机理,并分析系统基于不同元件的有源阻尼反馈的设计要求。最终在仿真平台中将对LCL滤波器并网系统中可行的有源阻尼方案与未加入有源阻尼的进网电流直接闭环控制方案的波形图进行对比,得出了所要验证的结论。
The inhibition mechanism of active damping on resonance is to take feedback control on output frequency components near the resonant peak.Based on this,this paper analyzes the mechanism of applying active damping technology to diff erent feedback positions of LCL filter,discusses the designing requirements of active damping feedback based on different components,compares the waveform diagram of the feasible active damping scheme in the LCL fi lter grid-connected system and that of the direct closed-loop control scheme without active damping the simulation platform,and fi nally obtains the conclusion to be verifi ed.
