As shown in Figure 1, this Vehicular accumulator cell is mainly tramway train and provides electric energy when independent operating.So-called independent operating, namely when no touch net and third-rail feeding, relies on vehicle power institute accumulate normally to run.This unit is made up of ultracapacitor and battery pack, and this kind of combination had both had super capacitor charging fast speed feature, had again the advantage of battery pack electric discharge lasting stability.This power-supply system mode of operation can be divided into three phases: platform charge condition, operation discharge regime and regenerative brake charge condition.It is below each state description.
Platform charge condition: this stage, storage battery only completes charging energy-storing work, and train electricity consumption is provided by platform.Train is in platform to be stopped, rise pantograph and introduce DC 750V electric energy from station air wire, flow through the circuit protection device such as lightning arrester, Qb, through isolation and switching device etc. to after electric energy process, become train available electrical energy, so far power flow is divided into two-way: a road flows into auxiliary inversion unit, DC 750V electric energy is converted to AC 380V/220V electric energy and assists consumer for train; Another road in the participation of energy storage management control unit directly to the super capacitor fast charging in storage battery, simultaneously by super capacitor to battery charging.
Run discharge regime: be about to start, stop super capacitor charging, disconnect station contact system, fall pantograph, on car, consumer (traction system and auxiliary consumer) is by storage battery power supply.Start, super capacitor discharges, and electric energy flows into traction unit through traction inversion unit (VVVF) variable-frequency variable-voltage.Startup completes, and train changes by storage battery power supply, and electric energy is delivered to current consumer after subordinate inverter and traction invertor process respectively.Super capacitor is to battery charging, and this process continues in operational process always.
Regenerative brake charge condition: train braking, storage battery stops powering to traction system, and under regenerative brake detection control unit controls, train starts regenerative brake.In this stage, electrical motor becomes electrical generator, and train momentum is converted into electric energy, to reach deceleration object.Electric energy is converted into after DC 750V by traction system through traction invertor, and to super capacitor charging under energy storage management control unit participates in, super capacitor is to battery charging simultaneously.
In order to make up the deficiency of existing electric power system, do not affect again the supply regular power of tramway train, the invention provides a kind of railroad car power supply plan, the demand of vehicle electrical system can either be met, all inconvenience that contact system, the 3rd rail and vehicle-mounted energy storage for power supply system are brought can be solved again.
This programme does not adopt contact system or third-rail feeding pattern, required electric energy is not obtained from outside vehicle power supply facilities in operational process, can run by self institute's accumulate, specific implementation process can be divided into two parts according to the state of vehicle: run power consumption state and stop energy storage state.Run power consumption state: vehicle sends signal, disconnect station power-supply battery group and be connected with station cable, make station cable power down maintain safe condition, vehicle pantograph is packed up, and vehicle brings into operation, and the start-up period of vehicle is powered by super capacitor.Starting completes, and enters stable operation stage, and change and powered to traction system and auxiliary using electricity system by storage battery, super capacitor is to battery charge.The solar energy-electric energy that station power-supply battery group is provided by station and common power frequency alternating current power supply charging, ensure lower subnormal use.Braking and stop energy storage state: vehicle applies braking, and super capacitor is drawn regenerative brake and produced electric energy to battery charge.After vehicle arrives at a station, stretched pantograph, vehicle sends control signal, makes station air wire charged, utilizes passenger getting on/off time remaining to charge, charges to super capacitor.
Power consumption running state: departures, pantograph is packed up, cab signal sending set sends signal simultaneously, platform signal receiving device receives train starting signal, cut off the connection between station power-supply system and station air wire, make station air wire be in the safe condition of dead electricity, train starting, powered to traction system by super capacitor, train starting.Starting completes, and provides electric energy by storage battery to traction system, and super capacitor turns to and continues charging to storage battery, ensures the persistence of train operation.Meanwhile, provide direct supply by solar panel photovoltaic generating system and 380V/220V electric power system to station power supply (battery pack), to its charging.
Energy storage halted state: train arrival, disconnecting the electric energy of storage battery to traction system provides, and connects super capacitor and traction system, starts regenerative brake.In this process, traction system fills energy by continuing to super capacitor.Train enters the station, and cab signal transmission and reception apparatus sends signal to platform Signal reception sending set, connects the electric power supply of station power-supply system and station air wire, makes station air wire with the required DC 750V electric power of train charging.Meanwhile, pantograph rises, powered with station conductive cable contacts, charges to super capacitor.Treat that train enters the station stopping, utilizing the passenger getting on/off time, pantograph and station air wire continuous contact powered, super capacitor charges continuously and healthily.Carrying completes, and train enters again power consumption running state.
The beneficial effect of this new-type power supply plan is:
While guarantee vehicle normally runs, without the need to overhead cable, on the appearance of the city without impact, safety, reliably; Have no special requirements to environment for use, cost is lower, easy to maintenance; Power compared to pure super capacitor, this programme both make use of the advantage of super capacitor, had effectively avoided deficiency again, can permanent supply.
