中文摘要:

摘要：静止无功发生器（SVG）能够显著地抑制和达到实时补偿效果。对于这一优势，本文采取基于T型三电平变流器拓扑结构的SVG作为研究对象，通过分析获得了系统模型，是一种存在耦合项的模型；因此为了实现解耦控制，提出了一种新型的状态反馈式补偿器，使得SVG输出电流能够稳态无误差地跟踪期望信号。同时也通过相应的控制实现了直流侧电容电压的均衡与稳定。最后在仿真软件MATLAB软件中进行了验证，为三相三电平SVG的研究与发展提供了基本保障和良好的平台。

Abstract: The static var generator (SVG) can significantly suppress and achieve real-time compensation. For this advantage, the SVG based on the T three level converter topology is taken as the object of study, the system model is obtained by analysis. It is a kind of model with coupling term. Therefore, a new state feedback compensator is proposed to realize decoupling control, the output current of SVG is guaranteed to track its desired signal without any error. For the DC side capacitor voltage balancing problem has also taken some control. The simulation model verify the effectiveness of the proposed control method. It provides basic guarantee and good platform for the research and development of the three-phase three level SVG.
