摘要： 针对电气化铁路智能牵引变电所发生进线电源失压或牵引变压器故障，备用进线电源与备用牵引变压器自动投入问题，提出了基于GOOSE与SMV的网络化自投方案。将自投程序固化至2台既有主变测控装置，装置与装置之间、装置与智能组件之间通过GOOSE信号传递闭锁信号、开关分合闸信号或开关位置信号；合并单元通过SMV向装置传递电压、电流等模拟量。运行牵引变压器侧的主变测控装置作为自投的主用装置，另一台主变测控装置作为自投备用装置，确保自投功能顺利实现。现场试验结果验证了方法的有效性与正确性。

Research and application of networked auto switch function of intelligent traction substation

Abstract： Aiming at the problem of auto switch of emergency incoming power supply and standby traction transformer in the intelligent traction substation of electrified railway due to voltage loss of incoming power supply or fault of traction transformer, a networked auto switch scheme based on Goose and SMV is proposed. The auto switch program is solidified to two existing traction transformer measurement and control devices. Locking signal, switch opening and closing signal or switch position signal are transmitted between devices and between devices and intelligent components through Goose. The merging unit transmits analog quantities such as voltage and current to the device through SMV. The traction transformer measurement and control device at the side of the running traction transformer is used as the main device for auto switch, and the other traction transformer measurement and control device is used as the standby device to ensure the successful accomplishment of auto switch function. The field test results verify the effectiveness and correctness of the method.
