Research on Intelligent Traction Substation Technology of High-speed Railway
Research purposes:The intelligence of high-speed railway traction power supply system is an important component of high-speed railway intelligence,and the intelligent traction substation is the core of the intelligence of traction power supply system and the trend of intelligent development of traction power supply system.At present,the intelligent technology of high-speed railway traction substations in China is in the initial stage of development,and the level of intelligent technology is relatively low.This paper conducts research on the intelligent primary equipment,wide area protection,auxiliary monitoring and other technical solutions of traction substations,and proposes a system solution to achieve intelligent traction substations.Research conclusions:(1)The technical characteristics of intelligent traction substations are summarized from six aspects,facilitating a deeper understanding of intelligent traction substations.(2)The intelligent traction substation adopts a"three layer,two network"layout,with a more simplified and clear structure.(3)The intelligent solution for primary equipment is recommended to use integrated and integrated equipment for new equipment,and externally mounted and separated equipment for renovation equipment.(4)The use of networked wide area protection has achieved isolation of traction network fault sections and self-healing reorganization of power supply arms,achieving intelligent control between substations.(5)The research content of this paper can provide technical reference for the intelligence of traction substations.
