在两相静止坐标系下采用改进的PR控制器实现对并网逆变器的控制,同时引入电容电流反馈实现了对LCL滤波器存在的固有电流谐振进行抑制控制,大大简化了并网逆变器控制算法的复杂性。通过实验对所提出的控制策略进行验证,实验结果表明,所提出的控制策略能控制感应全功率风电机组平稳发电运行,具有功率因数调节方便、无冲击并网等优点。 In the two-phase stationary coordinate system, an improved PR controller is used to control the grid-connected inverter. At the same time, the capacitive current feedback is introduced to suppress the inherent current resonance of the LCL filter, which greatly simplifies the grid-connected inverter Complexity of control algorithms. The proposed control strategy is verified through experiments. The experimental results show that the proposed control strategy can control the smooth operation of induction full-power wind turbine with the advantages of convenient power factor adjustment and no impact on grid connection.
