Abstract
The energy storage type electric propulsion traffic method of supplying power to that the present invention relates to, including: facility prepares；Vehicle pull-in charges, and vehicle sets off with storage battery power supply；Enter rolling stock section of master station at the end of operation and carry out degree of depth discharge and recharge, in case run next time.After using the present invention, vehicle only needs to carry out AT STATION quick charge, is provided electric power by accumulator completely when travelling between standing, so can erecting contact net the most AT STATION, without arranging power supply facilities between station, thus right of way, the view restriction to power supply mode in effectively overcoming city.
Description
Technical field
The present invention relates to a kind of energy storage type electric propulsion traffic method of supplying power to, be particularly suited for track traffic.
Background technology
Conventional rails traffic has two kinds of power supply modes, and one is that overhead contact line is powered, and another kind is that conductor rail is powered.The shortcoming that conductor rail is powered is: on ground line, safety in utilization is the highest, needs to cut off, and need Exclusive Right of Way at electricity segmentation with track switch；The shortcoming of overhead contact line is: device is relatively easily generated fault and inconvenient maintenance, and establishes catenary mast on ground and elevated line and can affect urban look.
Summary of the invention
The technical problem to be solved is: overcome the problem that prior art exists, it is provided that a kind of energy storage type electric propulsion traffic method of supplying power to, can effectively overcome right of way, the view restriction to power supply mode in city.
The technical scheme that the present invention solves its technical problem is as follows:
Energy storage type electric propulsion traffic method of supplying power to, comprises the following steps:
The first step, employing roof have the electric traction vehicle of pantograph, add holding storage battery on vehicle；Use the overhead contact line being only located at station；
When second step, vehicle enter station, the pantograph rising bow of vehicle is connected with contact net, makes vehicle battery start to charge up, and the charging interval is less than or equal to the dwell time；
3rd step, at the end of the dwell time, vehicle rolls station away from, vehicle pantograph fall bow, accumulator power to vehicle, makes vehicle continue to travel；When vehicle enters next anchor point, it is judged that this anchor point is station or rolling stock section of master station, if station then goes to second step, if rolling stock section of master station then goes to the 4th step；
4th step, vehicle battery is carried out degree of depth discharge and recharge, until vehicle battery is completely filled with, in case vehicle runs next time.
The technical scheme that the present invention is the most perfect is as follows:
Preferably, in the first step, overhead contact line is the rigid suspension catenary using CTA150 copper silver contact line.
Preferably, in the first step, accumulator has two groups, respectively lithium-ions battery, and vehicle can be maintained after accumulator is fully charged to run at least 8km under full-loading condition.It is highly preferred that the energy of accumulator be 49kWh, capacity be 92Ah.
Preferably, in second step, using double contact line large current charge mode during charging, static maximum charging current is 500A, and dynamic maximum charging current is 800A.
Preferably, in the 3rd step, when vehicle is positioned at the section at two stations, if the time of staying more than 3 minutes, then disables air-conditioning equipment or auxiliary equipment on car.
After using the present invention, vehicle only needs to carry out AT STATION quick charge, is provided electric power by accumulator completely when travelling between standing, so can erecting contact net the most AT STATION, without arranging power supply facilities between station, thus right of way, the view restriction to power supply mode in effectively overcoming city.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.But the invention is not restricted to given example.
Embodiment
The energy storage type electric propulsion traffic method of supplying power to of the present embodiment, comprises the following steps:
The first step, employing roof have the electric traction vehicle of pantograph, add holding storage battery on vehicle；Use the overhead contact line being only located at station；
Wherein, overhead contact line is the rigid suspension catenary using CTA150 copper silver contact line；Accumulator has two groups, respectively lithium-ions battery, and vehicle can be maintained after accumulator is fully charged to run at least 8km under full-loading condition；In the present embodiment, the energy of accumulator is 49kWh, capacity is 92Ah, so can ensure that vehicle when electric power system fault still reliable accumulator drive and travelled full journey.
When second step, vehicle enter station, the pantograph rising bow of vehicle is connected with contact net, makes vehicle battery start to charge up, and the charging interval is less than or equal to the dwell time；
Wherein, employing double contact line large current charge mode during charging, static maximum charging current is 500A, and dynamic maximum charging current is 800A, so gets final product traveling between effective refilling station and is consumed ground electricity.
3rd step, at the end of the dwell time, vehicle rolls station away from, vehicle pantograph fall bow, accumulator power to vehicle, makes vehicle continue to travel；When vehicle enters next anchor point, it is judged that this anchor point is station or rolling stock section of master station, if station then goes to second step, if rolling stock section of master station then goes to the 4th step；
Wherein, when vehicle is positioned at the section at two stations, if the time of staying more than 3 minutes, then disables air-conditioning equipment or auxiliary equipment on car, so can effectively save power supply.
4th step, vehicle battery is carried out degree of depth discharge and recharge, until vehicle battery is completely filled with, in case vehicle runs next time.
The present embodiment uses overhead contact line to be charged AT STATION, does not set contact net, accumulator provide power between standing.Station contact net is installed only at platform region；Pantograph rising bow during vehicle pull-in, utilize the time of passenger getting on/off after arriving at a station, it is boost battery charge by contact net while platform stops, once charging can make to continuously drive the row charging again of next platform of arrival by the electric energy stored, departures rear vehicle fall bow, by the independently-powered operation of accumulator to next station, without installing power supply facilities between standing.
Compared with traditional power supply mode of prior art, the present embodiment low cost, less investment, easier, it is not necessary to bury the power supply unit of precision in ground rail region underground, be not required to Exclusive Right of Way；And compared with the contact net power supply mode of all fronts, platform sets contact net the most AT STATION, contact net and platform canopy combine together in visual effect, bring out the best in each other, and do not set contact net between standing, and not only protect the landscape in city but also improve the aesthetics in city.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
