摘要
为了解决多个逆变器并联时的相位同步和振幅平衡问题,提出了在控制电路中加入重复控制器的控制方案,它可以实现稳态无静差控制,输出和输入的相位完全一致,可以用于多个静止变频电源的直接并联.仿真结果证明了在满足小增益稳定条件下该方案的可行性.
A controller scheme that the repetitive controller can be put in the control circuit is presented in this paper, to achieve the same phase and balanced amplitude while multi-inverters being in parallel. The scheme can be used for static zero error control, the same phase of output and input and the multi-inverters directly in parallel as well. Simulation results show that the scheme is feasible, under the condition of low-gain stability.
