摘　　要：本文通过在5.12汶川大地震后新津变电站为给金马变电站提供备用电源而自己失去备用电源的问题入手,对现有备用电源自动投入装置的原理及充放电动作逻辑进行了详细的分析,提出一种能实现自适应双向互投的备自投方案,并对该方案的充放电条件及动作逻辑进行了具体研究,最后把该方案实例运用到新津变电站中解决了之前现有备自投不能解决的新津站无备用电源问题。After 5·12 Wenchuang earthquake XinJin substation lost its standby power because of supplying electric energy to JinMa substation, from which current reserve power source automatic connection equipment’s principle, charge and discharge’s logical action was analyzed. Then one new scheme of adaptive bidirectional auto-switch-in device of stand-by power supply was proposed, based on which charge and discharge’s logical action was been studied. At last, the scheme was applied to Xinjin substation’s operation, and the problem that current reserve power source automatic connection equipment lost its standby power was resolved.
