| Popis: | Objective The structure of DC (direct current) traction power supply system for urban rail transit is complex and without any backup power supply. Once a malfunction occurs, it may directly lead to a train-stopping accident. In view of the shortcomings of the traditional traction power supply system bilateral tripping scheme exposed in actual projects, as well as the current low intelligence level in DC traction power supply system, it is necessary to study and propose a scheme to improve the reliability of bilateral tripping in DC traction power supply system intelligentization means. Method A bilateral tripping and self-healing scheme for DC traction power supply system based on GOOSE (generic object oriented substation event) communication is proposed. The scheme constructs GOOSE process layer communication network within the DC traction power supply system, achieving bilateral tripping and self-healing reconstruction of DC traction power supply system via the rapid real-time exchange of various information within and between traction substations. Laboratory simulation and field verification are carried out regarding the proposed scheme. Result & Conclusion The bilateral tripping and self-healing scheme for DC traction power supply system based on GOOSE communication has higher reliability, better real-time performance and higher intelligence level for wide application. |
