摘　　要：多模块化UPS供电系统便于系统扩容,提高了系统的稳定性。逆变器之间的并联控制为系统的核心,给出了一种基于有功功率与无功功率检测的全数字化无线控制方案。对方案的重要环节如数字锁相环的设计,有功功率无功功率的检测,下垂特性控制进行了分析。利用Saber软件的MAST语言完成相关模块的建模仿真,对控制方案进行了验证。The multi-module UPS can flexibly implement expansion of power system capacities and improve the system stability. The parallel control between inverters is the key factor of the system. A digital control scheme for parallel-connected inverters without communication wires was presented. The wireless control tech- nique is based on the measuring of active power and reactive power. The important links of the scheme such as the design of digital phase-locked loop, the measuring of active power and reactive power and the droop method were analyzed. The modeling and simulation are carried out, using the MAST Language in Saber, to demon- strate the effectiveness of the control scheme.
