Abstract

The protection of DC traction supply systems plays a very important role in guaranteeing the safety and reliability of DC traction supply systems for subway vehicles. It should trip the fault installation selectively and quickly when the fault occurs. Therefore, by establishing a mathematics simulation model of DC traction supply system matching the actual metro state, it provides theoretical basis for studying the principle of the protection, scheme configuration and setting the fixed value. Through analyzing the typical DC traction supply system of subway and its simulation calculation, an adaptive microprocessor-based protection scheme in DC traction power system is presented.
