本文主要研究采用旋转参考系控制策略的单相并网逆变器的性能。单相并网逆变器在小型可再生能源与电网的连接中得到了广泛的应用。当然，这些系统的单相结构无法使用一些众所周知的三相控制策略。克服这一限制的一种方法是虚拟地生成正交量，然后利用现有的三相控制方法。这种方法需要一个相移模块来生成额外的控制信号。在本文中，从动态和稳态性能的角度对用于完成此任务的几种方法进行了研究和比较。因此，系统的完整状态空间模型被导出并线性化以用于小信号研究。给出了不同方法之间的比较结果。
This paper is concerned with the performance investigation of single-phase grid-connected inverters in which rotating reference frame control strategy is used. Single-phase grid-connected inverters have found wide applications in interfacing small renewable energy sources to the grid. Naturally the single phase structure of these systems prevents using some well-known three-phase control strategies. One method to overcome this limitation is to virtually generate an orthogonal quantity and then exploit the existing three-phase control methods. This approach requires a phase-shifting block to generate the additional control signal. In this paper, several methods used to accomplish this task are investigated and compared from the standpoints of dynamic and steady-state performance. Therefore, the complete state-space model of the system is derived and linearized for small-signal studies. The results of comparison between different approaches are given.
