摘要
介绍了近年来变电站直流系统在技术上的一些改进和对智能型直流系统的配置要求,重点介绍高频开关电源模块数量选择和蓄电池容量选择,并对最近设计工作中出现的新问题,如不间断电源系统(UPS)逆变电源与通信、保护电源合一的问题作了简要介绍。
A number of technologic improvements in DC system in recent years are introduced,and configuration demands on intelligent DC system,are provided to analyze how to select the module numbers of high frequency switching power supply and battery capacity. Moreover,considering the new issues in design,a little experience is briefly recommended about the DC power supply combination of UPS inverter,communication and protection power supplies.
