A Multiattribute and Multidimensional Based Comprehensive Evaluation Method for New Multipulse Integrated Metro Traction Power Supply System

To improve the comprehensive performance of the metro traction power supply system (MTPSS), a new multipulse integrated metro traction power supply system (MI-MTPSS) is proposed in this article. The configuration and characteristics of MI-MTPSS are introduced, and based on the practical bilateral-ring power supply structure, a series of MTPSS-combinations with different standby equipment have been constructed. Meanwhile, a multiattribute and multidimensional based comprehensive evaluation method is proposed and adopted for evaluating the MTPSS-combinations comprehensively and quantitatively. According to the practical data, the practicability and reliability of the system are verified, and the MI-MTPSS is expected to be used in an industrial application in the future.
