摘要
针对逆变器并联系统中的零序环流问题,提出一种基于空间矢量脉宽调制(SVPWM)的零序环流抑制算法.在引入虚拟阻抗后,动态调节SVPWM中零矢量的作用时间,达到环流抑制的目的.搭建逆变器并联系统的Simulink仿真模型,验证基于SVPWM的零序环流抑制算法.结果表明,在输出滤波电感不同的条件下,零序环流峰值从±4A逐渐减小至 0左右.
Abstract
Aiming at the problem of zero-sequence circulation in the inverter parallel system,a zero-sequence circulation suppression algorithm based on space vector pulse width modulation(SVPWM)was proposed.After the virtual impedance is introduced,the action time of the zero vector in the SVPWM is dynamically adjusted to achieve the purpose of circulation suppression.A Simulink simulation model of the inverter parallel system was built to verify the zero-sequence circulation suppression algorithm based on SVPWM.The results show that the peak value of zero-sequence circulation gradually decreases from±4 A to about 0 under the condition of different output filter inductances.
