Urban rail transit traction power supply dynamic model simulation testing system

Abstract

The embodiment of the invention discloses an urban rail transit traction power supply dynamic model simulation testing system. The urban rail transit traction power supply dynamic model simulation testing system comprises a main power substation with first capacity, a traction step-down power substation with second capacity, a rail and a vehicle to be tested, wherein the main power substation is used for reducing voltage of first alternating current and outputting second alternating current to the traction step-down power substation; a ratio of the first capacity to the capacity of the main power substation in a traction power supply system is a first preset value; a ratio of the second capacity to the capacity of the traction step-down power substation in the traction power supply systemis a second preset value; the traction step-down power substation is used for reducing voltage of the second alternating current and converting the alternating current to direct current and outputtingfirst direct current to the vehicle to be tested, so that the vehicle to be tested can run on the rail under driving of the first direct current. Scientific experimental research is carried out on aphysical model, so that the most real result can be obtained; meanwhile, the establishment process of the physical model is simple, and then the problems that the existing simulation result is inaccurate and the whole model establishing process is complicated are solved.
