摘要
为了提升电力通信系统的稳定性,提出基于等价输入干扰的电力通信不间断电源(Uninterruptible Power Supply,UPS)并联控制策略.基于电源系统运行状态监测结果,设计基于等价输入干扰的并联控制器,求解并联控制器的参数,通过前馈修正方法,实现UPS的高效并联控制.实验结果表明,基于等价输入干扰的电力通信UPS并联控制方法在长时间运行中表现出更优秀的稳定性,可以为电力通信系统的稳定运行提供有力保障.
Abstract
In order to improve the stability of the power communication system,a parallel control strategy for power communication Uninterruptible Power Supply(UPS)based on equivalent input interference is proposed.Based on the monitoring results of the power system operation status,design a parallel controller based on equivalent input interference,solve the parameters of the parallel controller,and achieve efficient parallel control of UPS through feedforward correction method.The experimental results show that the parallel control method of power communication UPS based on equivalent input interference exhibits better stability during long-term operation,and can provide strong guarantees for the stable operation of power communication systems.
