| 摘 要： | 将电网电压定向矢量控制与比例谐振(PR)控制相结合的控制策略应用于三相光伏并网系统中,实现逆变器的并网控制。该控制策略比传统PI调节器的双闭环电网电压定向控制更简便,不需要复杂的坐标旋转变换和前馈解耦控制。同时,PR控制器可以很方便地实现并网电流低次谐波的补偿。仿真结果验证了该系统的结构和控制策略的有效性,可提高电网的电能质量。

| Abstract: | The strategy of grid voltage oriented vector control combined with PR(proportional resonant)control is applied in three-phase photovoltaic grid-connected system to achieve the grid-connected of inverter.The grid voltage oriented control combined with PR control is easier compared with conventional double close-loop PI(proportional integral) control,without complex coordinate rotation and feedforward decoupling.PR controller could compensate low order harmonic of grid current easily.Simulation results verified the effective of PV grid-connected systerm and control strategy,could improve the power quality. |
