LCL滤波并网逆变器的控制策略

本文关于LCL滤波并网逆变器的控制研究，研究了最合适的关于LCL滤波并网逆变器的控制方案。在开关的频率保持在同一个水准的时候在一个开关的周期内，研究组进行了对于逆变器的多次采样研究，有效地减少了在数字技术下控制的延时情况，提高了系统中本来的控制范围与延时时间。在定量分析的方式下，小组中的研究人员已经证实的开展了对LCL滤波并网逆变器本质性能的研究，分析了它的优势性能。与常规有源阻尼多环结构相比，该方案采用电流单环控制即可实现系统稳定，无需增加传感器，从而简化了控制结构。在最后，研究人员也同时通过了实验来对LCL滤波并网逆变器的性能进行了验证分析。

Control strategy of grid connected inverter with Yang Wenchi LCL filter

In this paper,a grid connected inverter with LCL filter control research,the control scheme of the most suitable for grid connected inverter with LCL filter.In the switching frequency remained at the same level of in a switching period,study group were for inverter multiple sampling study,effectively reduces the delay in digital control,to improve the system in the original control and delay time. In quantitative analysis,group of researchers has confirmed the carried out research on grid connected inverter with LCL filter is the essential properties,analyzes its performance advantages.With conventional active damping polycyclic structure.Ratio,the scheme using the current single loop control system can achieve a stable, without increasing the number of sensors,thus simplifying the structure control. Finally, the researchers also at the same time,through the experiment to the performance of grid connected inverter with LCL filter were analysis and verification.
