Description
Technical field
It is electric locomotive used in particular by the Tunnel Engineering of distributed integeration the present invention relates to a kind of power module management system
Supercapacitor module management system.
Background technique
Electric locomotive is a kind of pulling equipment of rail vehicle transport, and power is to drive vehicle wheel rotation using traction electric machine, is borrowed
The frictional force between wheel and rail level is helped, locomotive is made to orbit；This method of operation, its tractive force are not only towed electricity
The limitation of machine power, the friction also between by wheel and rail level restrict；The gradient that locomotive transportation can travel is restricted, conveying track slope
Degree generally 3 ‰, the local gradient is no more than 30 ‰.Tunnel Engineering electric locomotive is common a kind of traction in tunnel construction
Electric locomotive has the characteristics that tractive force is big, speed is high, carrying capacity is strong.Existing Tunnel Engineering electric locomotive mostly uses tradition
Lead-acid batteries are as the energy, and lead-acid accumulator is made of electrode mainly by lead and its oxide, and electrolyte is sulfuric acid solution
A kind of battery；Under discharge condition, positive main component is brown lead oxide, and cathode main component is lead；Under charged state, just
The main component of cathode is lead sulfate.The major advantage of lead-acid accumulator is voltage stabilization, cheap, the disadvantage is that than can be low
(i.e. the electric energy of per kilogram accumulators store), service life is short and daily maintenance is frequent；To constrain Tunnel Engineering electric locomotive
Carrying capacity, working efficiency.
Super capacitor be it is a kind of by polarized electrolytic matter come a kind of electrochemical element of energy storage, it is different from traditional chemistry
Power supply is a kind of power supply between traditional capacitor and battery, with property, relies primarily on electric double layer and oxidation also
Former fake capacitance charge stores electric energy.But it is not chemically reacted in the process of its energy storage, and this thermal energy storage process is reversible,
Therefore supercapacitor can be hundreds of thousands of times with repeated charge, and will not pollute.In addition, super capacitor is with very high
Power density is 10-100 times of battery, is suitable for short time high-power output, charging rate is fast, mode is simple.With the energy
The application of the development of new technology, super capacitor is gradually extensive, such as: (1) large scale supercapacitor can be used in train and subway
Brake system on, also can for material carry engineering truck provide energy output；Medium size supercapacitor can be used in too
In terms of positive energy collection of energy, because it has the characteristic that can be worked at high temperature；48V supercapacitor applications are in automobile；Small ruler
Very little supercapacitor then has very big contribution to the continued power of communications service and computer memory system storage backup power supply etc..(2)
The Low ESR of supercapacitor be for current many high power applications it is essential, for fast charging and discharging, super capacitor
The small ESR of device means bigger power output, charges within several seconds, a few minutes electric discharge；For electric tool, electronic toy etc..
(3) in ups system, supercapacitor provides instantaneous power output, as engine or the standby electricity of other uninterrupted systems
The benefit in source.(4) it is supported for the power when bus is switched to another power source from a kind of power source.(5) can low current,
Long lasting for electric discharge, the backup power supply as computer storage.(6) instantaneous power pulse application, important storage, memory system
The short time power of system is supported.
With the development of new technology of energy, the power supply of Tunnel Engineering electric locomotive is gradually substituted for by traditional lead-acid accumulator
Using super capacitor mould group as the new energy of core.To realize that super capacitor in the application of Tunnel Engineering locomotive haulage, first will

Join, connect multiple super capacitor mould groups to meet rated power and the voltage requirement of electric locomotive.State prison is carried out to monomer capacitor
Survey is easier, but highly difficult to the super capacitor group monomer capacitor working state monitoring of series, parallel together, needs to solve
Certainly number of leads it is too many, there are common mode interference, altogether the problems such as.Due to supercapacitor internal structure, electrode and electrolyte material
The characteristic of material, so that supercapacitor shows the characteristic different from ideal capacitor or battery, to its model and state-of-charge
(State Of Charge, SOC) estimation method is also studied less at present.And due to the difference of supercapacitor monomer performance
Different, it is inconsistent to lead to the problem of monomer SOC rate of change during series, parallel charge and discharge, shows monomer capacitor
Voltage change it is unbalanced.If the small monomer capacitor of capacity will overcharge or over-discharge without balanced management, capacity is big again
It is not fully utilized；This will seriously affect the generation of the service life cycle of super capacitor mould group, while also affect tunnel
Tractive force, the speed of service, load-carrying ability of engineering electric locomotive etc..
The power as required for Tunnel Engineering electric locomotive is big, operating voltage is high, need a fairly large number of mould group into
Row series, parallel uses, and the management system (Battery Management System, BMS) of working power is super capacitor
Tie between user is to be able to improve the utilization rate of super capacitor, prevents super capacitor from occurring overcharging and mistake
Degree electric discharge need to carry out real-time tracking super capacitor operating status and parameter detecting, acquire super capacitor charging and discharging state in real time, be surplus
Remaining electricity and distance travelled estimation, temperature management, Balance route, fault diagnosis, capacitor condition predicting and report between capacitor monomer
The work such as police, information monitoring, management of charging and discharging.Therefore, the BMS of Tunnel Engineering electric locomotive, which exists, needs to solve number of leads too
More, common mode interference, altogether the problems such as.The working environment of electric locomotive is complex, and electric locomotive super capacitor power source performance is by week
The influence in collarette border is very big, and excessively high and too low temperature can all influence service life and the capacity of battery.Simultaneously in SOC measurement
Fully consider temperature value at that time.Many parameters such as the remaining capacity and voltage of super capacitor, electric current, temperature, degree of aging
Related, BMS management system is needed to the accurate fast slowdown monitoring of the parameters such as monomer capacitance voltage, and there are monitoring parameters for existing system not
Comprehensively, the disadvantages of precision is not high, real-time is bad.
