REGENERATIVE DRIVE FOR SUBWAY TRAINS. PART 4: OVERALL SYSTEM PERFORMANCE

Vehicle energy consumption and savings for the Toronto Bloor-Danforth Subway Line are evaluated. Two vehicle loads are chosen (for this evaluation) indicative of rush-hour and nonrush-hour operation. A comparison test run shows the numerical simulation to be within a few percent of actual measured data. Evaluation of round trip results indicate energy savings as high as 33 percent for a large vehicle weight, but based on daily operation, savings are more realistically 26 percent. The effect of long coasts (5 percent) on actual station runs is again shown to be detrimental to the energy savings for the regenerative system.
