As shown in figure 1, this Vehicular accumulator cell is mainly tramcar provides electric energy in independent operating.So-called independent fortune OK, i.e., in the case of contactless net and third-rail feeding, can normally it be run by vehicle power institute storing up electricity.This unit is by super electricity Container and batteries are constituted, and such a combination had both had the characteristics of super capacitor charging is quick, again there are batteries to discharge The advantage of lasting stability.This power-supply system working condition can be divided into three phases:Platform charged state, operation discharge condition with And regenerative braking charged state.It is each state description below.
Platform charged state:This stage, battery is only completed charging energy-storing work, and train electricity consumption is provided by platform.Train Stop in platform, rise pantograph and introduce DC 750V electric energy from station overhead line, flow through the electricity such as arrester, high-speed circuit breaker Line protection device, through isolation and switching device etc. to electric energy processing after, as train available electrical energy, so far power flow is divided into two Road:Auxiliary inversion unit is flowed into all the way, and DC 750V electric energy is converted into AC 380V/220V electric energy for train auxiliary electrical equipment Use;Another road is direct to the super capacitor fast charging in battery in the participation of energy storage management control unit, while by surpassing Level electric capacity is to battery charging.
Run discharge condition:It will start, stop charging to super capacitor, disconnect station contact net, fall pantograph, car Upper electrical equipment (trailer system and auxiliary electrical equipment) is by storage battery power supply.Start, super capacitor electric discharge, electric energy is through traction Inversion unit (VVVF) variable-frequency variable-voltage flows into traction unit.Start completion, train changes by storage battery power supply, and electric energy is through auxiliary inversion Device and traction invertor are delivered to electrical appliance after handling respectively.Super capacitor is to battery charging, and this process is in running In be continued for.
Regenerative braking charged state:Train braking, battery stops powering to trailer system, detects and controls in regenerative braking Under unit control, train starts regenerative braking.In this stage, motor is changed into generator, and train momentum is converted into electric energy, with Reach deceleration purpose.Electric energy is participated in after trailer system is converted into DC 750V through traction invertor in energy storage management control unit Under to super capacitor charge, while super capacitor is to battery charging.
In order to make up the deficiency of existing electric power system, and the normal power supply of tramcar is not influenceed, the present invention provides a kind of Railroad car power supply plan, can either meet the demand of vehicle electrical system, can solve the problem that again contact net, the 3rd rail and A variety of inconvenience that vehicle-mounted energy storage for power supply system is brought.
This programme is not used in contact net or third-rail feeding pattern, running and not obtained from outside vehicle power supply facilities Required electric energy, can run, specific implementation process can be divided into two parts according to the state of vehicle by itself institute's storing up electricity:Operation power consumption shape State and stopping energy storage state.Run power consumption state:Vehicle sends signal, disconnects station power-supply battery group and connects with station cable Connect, station cable power down is maintained safe condition, vehicle pantograph is packed up, and vehicle brings into operation, and the start-up period of vehicle is by surpassing Level capacitances to supply power.Start and complete, into stable operation stage, change and powered from battery to trailer system and auxiliary electricity system, Super capacitor charges to battery.Solar energy-electric energy and common power frequency AC that station power-supply battery group is provided by station Charging, it is ensured that under subnormal use.Braking and stopping energy storage state:Vehicle applies braking, and super capacitor draws regenerative braking production Raw electric energy simultaneously charges to battery.After vehicle arrives at a station, pantograph is extended, vehicle sends control signal, makes station overhead line powered, Persistently charged, charged to super capacitor using the passenger getting on/off time.
Consume energy running status:Outbound, pantograph is packed up, while cab signal dispensing device sends signal, platform signal connects Train starting signal is received by device, the connection between cut-out station power-supply system and station overhead line is in station overhead line The safe condition of dead electricity, train starting is powered from super capacitor to trailer system, train starting.Start complete, from battery to Trailer system provides electric energy, and super capacitor is turned to persistently to charge to battery, it is ensured that the persistence of train operation.Meanwhile, by too Positive energy cell panel photovoltaic generating system and 380V/220V electric power systems provide dc source to station power supply (battery pack), to it Charging.
Energy storage halted state:Train arrival, disconnects battery and the electric energy of trailer system is provided, connection super capacitor is with leading Draw system, start regenerative braking.During this, trailer system persistently will fill energy to super capacitor.Train enters the station, and cab signal connects Transmit and receive device and send signal to platform signal transmission and reception apparatus, connection station power-supply system and the electric energy of station overhead line are supplied Should, make station overhead line with DC 750V electric power needed for train charging.Meanwhile, pantograph rise, with station conductive cable contacts by Electricity, charges to super capacitor.Treat that train enters the station stopping, using the passenger getting on/off time, pantograph persistently connects with station overhead line Touch by electricity, super capacitor charges continuously and healthily.Carrying is completed, and train enters power consumption running status again.
Originally the beneficial effect of new-type power supply plan is:
It is safe on the appearance of the city without influence without overhead cable while ensureing that vehicle is normally run, reliably;To using ring Border has no special requirements, and cost is relatively low, easy to maintenance;Powered compared to pure super capacitor, this programme both make use of super capacitor Advantage, and effectively avoided deficiency, can be with permanent supply.
