资料介绍

为抑制电网谐波电压对三相并网逆变器入网电流的影响,建立了三相并网系统αβ静止坐标系下的诺顿等效电路模型.在分析电网电压前馈控制和多谐振控制对电网谐波电压抑制效果的基础上,提出了一种电网电压前馈控制+多谐振控制的组合谐波抑制技术,并对不同策略下并网电流时域波形和谐波频谱进行对比分析.仿真结果验证了所提谐波抑制技术的正确性和优越性.

To suppress influence of grid voltage harmonics on grid current of three-phase grid-connected inverter,Norton equivalent circuit model of inverter system is established under the αβ stationary frame. A combination harmonic suppression scheme is proposed based on performance analysis of grid voltage feed-forward and multiresonant control schemes. Then the harmonic suppression performances of different schemes are analyzed and compared from the standpoint of time-domain and frequency-domain of grid circuit. Finally,simulation results are presented to demonstrate the correctness and superiority of the proposed schemes.
