The analysis of regenerative breaking power for Taipei Rapid Transit Systems Electrical Multiple Units

Abstract

This research is mainly investigating into the power variations between non-regenerative braking power mode and the regenerative braking power mode of the Electrical Multiple Units (EMU) which are used in Taipei Rapid Transit Systems (TRTS) Nangang, Banqiao and Tucheng lines. It also aims to find the optimal usage of the regenerative braking power, not only providing a reasonable planning of the substation capacity for construction at the initial stage in order to avoid possible waste on investment, but also effectively reducing loadings of the electric power facilities and the related power expenditure at the stage of operation. Moreover, it is expected that other metro authorities in our country will therefore pay more attention to the EMU's regenerative power utilization, and eventually apply it to the planning and design of the EMU regenerative power for all the railway systems.
