TA21 traction substation automatization system

Traditional traction substation system is designed based on watching with people.The system based on watching without people have been mainstream recently,but it is very difficult to satisfy the demand of watching without people indeed.New style traction substation automatization system developed up to date and applied to traction substation based on watching without people is introduced in this article. The composed structure of the system was analyzed and its function and characteristic was illuminated.Its typical applied pattern was discussed based on part of secondary circuits.The illustration above showed that the system can meet the need of substation watched without people indeed.
