摘要
UPS的并联冗余运行不仅可提高电源系统的容量,还可提高系统的可靠性。提出了一种分布式控制并联方案来实现多台逆变电源并联控制系统,并分析了逆变电源并联运行控制过程中的电压和电流特性。试验运行结果表明各模块均流效果好,控制策略可行,可达到比较理想的并联运行控制效果。
UPS parallel redundant power supply operation can not only enhance the capacity of the system, but also improve the reliability of the system. a parallel distributed control programs to achieve multiple parallel inverter power source control system was presented in this paper, and the voltage and current charactericitics were analyzed in the process of parallel operation of inverter power control. The test results show that the current sharing of the modules is effective, the control strategies are feasible and the control of the parallel operation is satisfactory.
