| 摘 要： | 针对泵站使用的蓄电池直流操作电源系统存在的问题，提出了采用“双整流器组冗余型直流电源系统”方案．该直流电源系统采用两套高频开关整流器组，两路独立交流电源输入，各自供一组高频开关整流器组，输出经二极管直接接至同一组直流母线．直流母线为单母线不分段，不设蓄电池组．正常情况下，两路独立的交流电源同时供电，两组整流器组中所有高频开关整流模块并列运行，共同承担全站的负荷电流．当其中任一路交流电源系统发生事故或某一组整流器组故障、检修退出运行时，正常的一组整流器组可单独运行，承担泵站的全部负荷．使用结果表明，这种设计具有交流电源无间隙切换、事故放电能力大、可扩容性强等优点，并可推广为多个交流电源同时供电，实现多交流电源不间断切换，进一步提高直流电源系统的可靠性．

| Abstract: | Regarding the current problem in the pumping station caused by DC operation power system from storage battery,"the double commutating redundancy DC power supply system" is proposed.It contains two sets of high frequency switch commutator with two independent ways of alternating current input.Each input supplies to one set of high frequency switch commutator and both of the output connect directly to the same direct current central wire through diode.The mother line is a single line without breaking and disconnecting to storage battery.Normally the two independent AC powers could supply power at the same time. All the high frequency switch commutating modules run together simultaneously to load the(electricity) of whole pumping station.Once one of the AC power system is out of use from accident,going down or termly maintaining,the other set could work independently to load the electricity of whole pumping station.The actual operation result proves that this design has the advantage of AC power supply continual switching without breaking,strong discharge capability during accident,and high expanding(capacity) etc.It could also be upgraded to multi AC power supplying electricity simultaneously to achieve the continual switching without breaking among multi power,thus could improve the reliability of the DC power.pumping station;DC power supply;double-commutating;pedundancy |
