| Summary: | 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. |
