Background technique

The biggest difference between smart substations and conventional substations is that the secondary system depends on the substation system configuration description file (SCD, System Configuration Description).

The secondary circuit of the smart substation mainly relies on optical fiber and network, replacing the traditional secondary cables, and the traditional terminals have also been replaced by "virtual terminals".

For relay protection maintenance personnel, the secondary circuit (virtual terminal, virtual circuit) of the smart substation has become a "black box". When overhauling relay protection equipment, especially relay protection maintenance test transmission equipment, there is no effective and fast means to locate the abnormal position of relay protection secondary circuit and action signal, and there is no convenient and intuitive relay protection maintenance test transmission means of process monitoring.
