资料介绍

在电力系统中,逆变电源作为调度数据网的供电电源,存在因控制模块损坏而导致全站通讯中断的风险。采用双电源供电方案,将变电站交流电源作为备用供电电源,提出一种不间断供电电路,能够实现调度数据网供电电源在逆变主电源与交流备用电源之间的自动切换。所提出的不间断供电电路所有辅助电源均由当前有效供电电源引出,即由主电源或备用电源提供,无需额外自备辅助电源。对双电源供电模式进行了分析,给出了不间断供电电路具体设计方案,并通过仿真和实验验证了所提出电路的有效性和可靠性。

In the power system,inverter power is the supply of the dispatching data network.It has the risk of the total station communication interrupt caused by the control module damage.A dual-power supply scheme was adopted.The AC power supply of substation was used as the backup power supply.An uninterrupted power supply circuit was proposed.It could realize automatic switching between the inverter main power supply and the AC standby power supply of the dispatching data network power supply.All the accessory power supplies of the proposed circuit were provided by the current effective power supply,i.e.the main or standby power supply.There was no additional accessory power supply.The dual-power supply modes were ana...
