摘　　要：并网逆变器需要及时跟踪电网电压,同时输出电压也要达到规定指标。目前已有多种并网逆变控制方法,均可以达到较好的控制效果。在静止坐标系下,比例谐振(PR)控制算法可以实现无静差跟踪控制,同时PR控制算法可以方便地实现谐波补偿。相比其他几种算法,PR控制算法简单,所需计算量小,有极大的应用前景。Grid connected inverter＇s output current waveform ought to be synchronized with the grid voltage,and must also meet with industrial standards.Nowadays,we have many control methods to do this with acceptable performance.Recently,a new proportional-resonant control method has been proposed.Running under stationary reference frame,it is able to regulate AC signals without static error.And harmonic compensation is quite simple using a PR controller.With its simplicity,PR control algorithm needs less calculation and can be widely used.
