摘　　要：针对链式网络变电站间不能同时使用备自投的问题,提出了一种远方备自投的解决方案。远方备自投装置利用光纤通道相互交换信息,通过串接变电站间的配合,实现远方备自投功能。远方备自投在韶关电网得到了实际应用,整组试验表明,该装置可有效提高供电可靠性,减少负荷损失。In view of the problem that the chain power grid substations can′t use automatic back-up power supply devices at the same time,aremote standby power supply automatic switching scheme is proposed.This device uses optical fiber channels to exchange information with each other,and realizes the function of remote automatic switching to backup power supply through the cooperation among serial substations.The remote automatic back-up power supply device has been applied in Shaoguan Power Grid.The experiments show that the device can effectively improve the reliability of power supply and reduce the load loss.
