摘　　要：在灾后重建项目中,应大力推广采用公共直流母线变频调速新技术,将同一时刻工作于不同状态的传动装置,科学、合理地整合在一起。实现逆变反馈能量在本系统内完成彼此的再生利用,从而使回馈电能的路径最短。达到用于整流单元和逆变单元的硬件容量最小,就可保证公共直流母线电压的稳定供给和将直流母线多余能量回馈给电网的目地。从而实现了再生能源的高效、合理利用。In the post-disaster reconstruction projects, the common DC bus variable frequency speed-regulating technology should be adopted to get the driver in different working state work together reasonably at the same time, which achieved the aim of recycle of the power feedback in this system and make the shortest path of power feedback. When capacity of the rectify unit and invert unit is minimum, stable supply for common DC bus voltage will be assured and feedback of the redundant energy of DC bus back to power grid will be achieved, then efficient and reasonable utilization of renewable resources will be realized.
