摘要
为保证模块化电源并联系统能独立、稳定地长期运行,详细分析了全数字化UPS中SPWM逆变电源并联运行过程中故障的判断技术及保护处理措施,并提出了系统保护控制策略及控制流程。
For assuring that the modularized power supply system in parallel operation can steadily and independently work over a long period of time, this paper analyzed fault estimation and the protective strategies about fully digitalized SPWM inverters in parallel UPS. System protection strategies and control flow are also presented and discussed in detail.
