A Research on the Load Calculation Method in Designing the Traction Power Supply for Integrated Subway – MCR

Abstract

This paper presents a load calculation method in the design of a traction power supply for integrated subways. Integrated subways have a large carrying capacity and the ability to balance between meeting travel needs and satisfying conditions such as high quality service, cost optimization for railway infrastructure construction, and installation of traction power systems. In an integrated model, the calculation of the traction power supply design is much more complicated than in other stand-alone models. This paper presents the research results on the load calculation method of a traction power supply for the operation of the system. The results show the feasibility of the method when applied to an asynchronous loading system and met the standards of IEEE P1653.2, EN 50328, and IEC 60146-1 in the design of the power supply for permitted overloads according to class VI.
