If the AC secondary circuit of the smart traction substation is abnormal,it will have a significant impact on the related relay protection functions,and then affect the safety and reliability of the traction power supply system.In order to solve the problem that the secondary AC circuit mainly relies on post-maintenance and improve the maintenance level,this paper studies the online diagnosis system of the secondary AC circuit of smart traction substation,proposes the system functions and algorithms,then designs and develops an actual online diagnostic system for a certain traction substation,which achieves some ideal results.
