Description
Technical field
The utility model relates to urban rail transit vehicles, particularly relates to a kind of rail traffic vehicle braking energy recycle device.
Background technology
Urban rail traffic vehicle braking energy recovery at present is in the line voltage scope, when brake voltage super or less than this scope in the time, the traction control unit by vehicle cuts off the electric energy to the electrical network feedback, all changes rheostatic brake into.The utilization of this electric energy must be satisfied the condition that has other trains to move simultaneously between two stations in addition, and this train could absorb and brake the electric energy that train feeds back this moment, otherwise the traction control unit of braking energy by vehicle consumes with regard to being automatically changeb to rheostatic brake.This method braking energy is most of to be consumed on car brakeing resistance, and the heat of generation distributes in the subway tunnel, and temperature improves year by year in the tunnel.Another energy recovery mode: the braking electric energy also is to feed back to electrical network, different is with feedback electrical network electrical power storage in the traction substation energy recycle device, can produce the problems referred to above equally, energy recovery is subjected to the restriction of line voltage size, limited the percent recovery of braking energy greatly, these plant area areas are big in addition, the cost of investment height.The utility model patent is based on vehicle from the energy recovery closed loop system as the disengaging electrical network of main body, and this method substitutes present rheostatic brake mode with part, and effective use of energy sources is used for the air-conditioning of interior or illumination etc. with the electric energy of its recovery.Overcome the voltage ripple of power network problem that present vehicle regenerating braking energy reclaims, constituted with vehicle from energy recovery closed loop control system as main body.Can not produce any impact to line voltage in addition, and this system only need absorb this section motor train unit energy, used super capacitor volume is less, is easy to power management and control, and mounting means is more flexible.
The existing urban rail transit vehicles method for saving energy that solves:
1, resistance energy-dissipating type regenerating braking energy regenerative apparatus.The main constant voltage way of recycling that adopts heterogeneous GTO/IGBT chopper and recovery resistance to cooperate.Braking energy consumes reclaiming on the resistance, is not used; And the resistance heat radiation also causes ambient temperature to rise, therefore when this device was installed in the underground substation, resistor box needed to place separately, and enough ventilation volumes need be taken measures to guarantee in this room, and install corresponding ventilation engine installation additional, also increased corresponding power consumption.
2, capacitor energy storage type or flywheel energy storage type regenerating braking energy regenerative apparatus.The main IGBT inverter that adopts is recovered to the regenerating braking energy of train in large value capacitor group or the fly-wheel motor.This method need be provided with bulky cond group and rotary machine flywheel gear as energy storage component, and the technical index of cond is also had very high requirement.
3, inversion feedback type regenerating braking energy regenerative apparatus.The main power electronic devices that adopts constitutes the high-power thyristor three-phase inverter, and the DC side of this inverter and the rectifier DC bus in the traction substation link, and it exchanges inlet wire and receives on the AC network.Because employing high-power thyristor, braking energy is directly fed back to electrical network, but because there is change of current breach in thyristor converter devices, harmonic content is big, so harmonic suppressor and power compensator must be set, cause secondary pollution and labile factor for easily the operation electrical network.
4, energy storage utilizes type regenerating braking energy regenerative apparatus again.Siemens has been developed the static closed-centre system of a kind of SITRASSES type, and the core component of this closed-centre system is a double layer capacitor.The brake energy from railway vehicles recovery system that the said firm develops can be two kinds of operational modes: automatic switchover voltage stabilizer pattern and energy saver mode under, the energy that turns back to power end is directly used in the vehicle of startup, and real-time is good.Also there are the following problems in this system: (1) energy can produce than multiple-harmonic in feeding back to the process of electrical network, pollutes electrical network, and needing increases corresponding harmonic wave control measure, causes increasing unnecessary expense expense; (2) the inverter cost of middle-voltage network needs is very high; (3) energy storage of substation's installation is bigger because of absorbing energy with super capacitor, so need bigger control of laying space and requirements at the higher level and power supply management device.
