Abstract

The invention provides a method and a device for performing comprehensive energy saving on an urban rail transit system. The method and the device are characterized in that a traction power supply system of the urban rail transit system is powered intermittently at stations and near road segments; an energy-saving AC permanent magnet synchronous motor is used as a traction motor of an electric transmission system of an urban rail transit train; and in braking, a supercapacitor set recycles the kinetic energy of the urban rail transit train. An in-train environment control system and a train control system are powered by a battery pack and a supercapacitor box. The battery pack and the supercapacitor box are charged at positions with electricity energy.

Description

technical field [0001] The invention relates to the field of urban rail transit, and more specifically relates to a comprehensive energy-saving method and device for an urban rail transit system. Background technique [0002] Urban rail transit refers to the transportation system composed of rail transit trains such as subways and urban light rails, rails, and power supply networks. At present, most of the working energy of urban rail transit trains comes from the power supply network. The power supply voltage of rail transit trains in my country is 1500v or 750v DC voltage power supply. The operation process is as follows: figure 1 As shown, the traction power supply device 1-4 of the traction power supply system supplies power throughout the whole process. The operation of any two rail urban rail transit trains is approximately divided into start-up acceleration section a, coasting section b, deceleration stop section c, and the corresponding current curve 1-2. The power ...
