摘　　要：传统的备自投不能实现各个设备之间的互操作,使整个电网的信息难以共享,且接线较复杂,难以维护与扩展。以IEC 61850为通信标准规范,设计了一种变压器数字化备自投的实现方案。详细分析了不同运行方式下的逻辑过程以及完成数字化备自投的实现方式,对备自投出现的特殊问题提出了一些解决方法。采用OPNET仿真软件对变压器备自投通信方式进行仿真验证。结果表明,数字化备自投具有较高的实时性,完全满足标准规定的4 ms。Traditional standby power supply automatic switching can not achieve interoperability between the various devices. It is difficult to share in the entire grid, and the wiring is more complicated, so it is difficult to maintain and expand. Using IEC 61850 for communication standard, a transformer digital standby power supply automatic switching implementation scheme was designed. The logical process under different operation modes was analyzed, some solutions for special problems of standby power supply automatic switching were proposed. OPNET software simulated the communication modes of the transformer digital standby power supply automatic switching. The results show the digital standby power supply automatic switching has high real-time, fully meets the standard requirement of 4 ms.
