Abstract In order to solve the problems of the traditional traction power supply system, such as the insufficient utilization of the regenerative energy of trains, the large fluctuation of DC power supply, the low power factor of AC network, a flexible traction power supply system scheme with the introduction of bidirectional converter is proposed. This paper introduces several typical working modes of flexible traction power supply system and the realization scheme of bidirectional substation. The key technologies such as bidirectional converter modeling, DC characteristic optimization and decentralized reactive compensation are studied. The hierarchical control structure of flexible power supply system is proposed to realize the flexible control of AC-DC hybrid system. The simulation model of urban rail flexible power supply system is established, and the system function and performance under typical application scenarios are verified, and the comprehensive optimization of the system is realized.

Key words： Urban rail transit flexible traction power supply hybrid energy saving
