Title Research On The Regenerative Braking Energy Recovery System Of Urban Rail Transit Train
Abstract
Frequent braking is one of the characteristics of urban rail transit, so the urban rail transit vehicle braking energy recovery will save a lot of energy. Rail brake energy recovery technology is an important research direction of urban rail transportation braking system.
In this paper, research the urban rail transit vehicles energy of brake recovery system. Describes the urban rail transit vehicles brake system, explained in detail the classification of urban rail transit braking technology and how it works. Describes the urban rail transit vehicles currently available in four brake energy recovery technology at home and abroad, were analyzed in four brake energy recovery system, working principle and application. And four kinds of brake energy recovery on the economy, energy recovery, grasp the situation of technology, prospects and other aspects of the country were analyzed and compared. According to a comparison designed to urban rail transit vehicles feedback type inverter braking energy recovery scheme , when the vehicle regenerative braking , regenerative energy back to the AC inverter rings serve the purpose of saving energy.
Program to maintain the existing diode rectifier based on the creation of the PWM converter as a deflector .It played the role of inverters in trains during regenerative braking. Meanwhile during peak periods PWM converter can participate in rectified voltage stability of traction network.
Key words Urban Mass Transit Regenerative braking Energy feedback PWM converter
