摘要:
 针对LCL型逆变器谐振尖峰以及对并网电能质量影响的问题，采用比例电容电流与并网电流叠加的电流反馈算法消除LCL型逆变器固有谐振尖峰带来的影响，并在比例谐振控制器基础上增加多个谐振环，用于抑制并网电流低频谐波和谐振电流含量，从而提升对电网电流控制的准确性和并网系统的稳定性。最后设计了2 kW并网逆变器LCL型滤波器参数，在Matlab/Simulink上仿真与实验平台验证了控制算法的可行性。
Abstract:
 Aiming at the problem of resonance peak of LCL inverter and its influence on grid connected power quality, the current feedback algorithm of superposition of proportional capacitor current and grid connected current is adopted to eliminate the influence of inherent resonance peak of LCL inverter. Several resonance rings are added on the basis of proportional resonance controller to restrain low-frequency harmonic and resonant current content of grid connected current, so as to improve the current to grid Accuracy of control and stability of grid connected system. Finally, the LCL filter parameters of 2kW grid connected inverter are designed, and the feasibility of the control algorithm is verified by the simulation and experiment platform on MATLAB/SIMLINK.
