摘要/Abstract

摘要： 随着风能、太阳能等清洁能源在电网中的应用,逆变器不可或缺.电网中的谐波和不平衡负载影响电网的电能质量,因此逆变器的控制策略及控制方法尤为重要.为提高电能质量,以三相四桥臂逆变器为模型,提出了比例积分PI、矢量谐振(vector resonant,VR)控制和重复(repetitive control,RC)控制相结合的复合控制方法.其中比例积分控制器能够抑制直流分量的干扰;矢量谐振控制器能够抑制特定频率且含量较高的谐波;重复控制器抑制多次且含量较低的谐波并减小稳态误差.仿真结果验证了所提控制方法能有效提高逆变器输出电压电流波形质量.

关键词: 逆变器, 矢量谐振, 重复控制, 谐波

Abstract: In the application of wind, solar and other clean energy in the grid,inverter is indispensable.Harmonic wave and unbalanced load affect the output of the inverter, the performance of the inverter control strategy directly affects the power quality.By combining proportional integral(PI), vector resonance(VR)control and repetitive control(RC),the compound control method is proposed.PI restrain the interference of DC component, the VR controller suppresses the low harmonics.RC suppresses the higher harmonics and reduce the static error, and improve the waveform qualities of converter output voltage and current.The simulation results verify the effectiveness of the proposed control method.

Key words: converter, vector-resonant(VR), repetitive control(RC), harmonic wave
