Traction station power line
Relay protection configuration and setting calculation principles
1 Scope
This standard specifies the basic principles, methods and requirements for the configuration and setting calculation of relay protection for the power supply lines of traction stations.
This standard is applicable to the power supply lines of traction stations for newly-built electrified railways of 110kV and above voltage levels
Consider three-phase or two-phase power. 110kV and above voltage grade power grid reconstruction, expansion of the traction station power supply line of electrified railway can be consulted
Follow the instructions.
