| Summary: | The new round of scientific and technological revolution has propelled the informatization of the urban rail transit industry into a stage of intelligent development, and hence the traditional construction mode and operation service mode have been gradually changed. However, due to diverse factors such as geographic environment, level of economic development, and population density, the development of rail transit in various cities in China is uneven. In order to promote the healthy and orderly construction of informatization and intelligence of the urban rail transit industry, top-level design is needed to coordinate development strategies, clarify construction goals, determine key tasks, and plan implementation paths. The advanced information and communication technology was used to realize real-time data interaction among traction substations, bidirectional converters, trains, signal system, and energy management and control system (ECMS) in this paper. From the perspective of traction grid source and load matching, energy utilization, power quality, and system security, an integrated, collaborative and shared urban rail transit smart traction power grid was built to implement systematical energy dispatch between trains and substations, load forecasting, fault location, and train operation plan optimization. Taking an actual metro line 2 of a certain city as an example, the effectiveness of the proposed smart traction power grid was verified on the road-network-vehicle integrated simulation platform. Finally, the key issues that need to be further studied and resolved in engineering practice were provided. |
