摘要:
当电网电压存在背景谐波时,LCL型并网逆变器的并网电流会产生明显的畸变。为了抑制电网电压背景谐波对并网电流的影响,对LCL型并网逆变器电压谐波抑制策略进行研究,在电网电压比例前馈控制策略的基础上,分析LCL型并网逆变器逆变侧电感值以及滤波电容值对电网电压比例前馈控制策略的影响,对两者进行综合性考虑。实验结果表明:减小逆变侧电感以及滤波电容均会增强电网电压比例前馈控制策略对电网电压背景谐波的的抑制能力,并且减小滤波电容拥有更好的抑制能力和更优良的经济特性。
Abstract:
When the background harmonics exist in the grid voltage, the grid current of the LCL grid-connected inverter will produce obvious distortion. In order to suppress the influence of grid voltage background harmonic on grid-connected current, the voltage harmonic suppression strategy of the LCL grid-connected inverter is studied. ba<x>sed on the grid voltage proportional feedforward control strategy, the influence of inverter side inductance value and filter capacitor value of the LCL grid-connected inverter on grid voltage proportional feedforward control strategy is analyzed, and both of them are comprehensively considered. The experimental results show that: reducing the inverter side inductance and the filter capacitor will enhance the suppression ability of the grid voltage proportional feedforward control strategy to the grid voltage background harmonics, and reducing the filter capacitor has better suppression ability and better economic characteristics
