As shown in Fig. 2, for according to the block diagram of the braking recovery system of the train of one embodiment of the invention.In order to Convenient for description, an energy-accumulating power station is illustrated only in this embodiment.Wherein, as shown in Fig. 2, distributor 203 and drawing electric network 1 It is connected with electric brake 201, there is node between distributor 203 and electric brake 201；One end of two-way DC/DC converters 204 It is connected with battery 202, the other end of two-way DC/DC converters 204 and the node phase between distributor 203 and electric brake 201 Even.
First controller 205 is used to prepare electric appliance 203 and two-way DC/DC converters 204 in train braking time control and will brake Electric energy feedback is opened to Traction networks 1, such as by distributor 203, and two-way DC/DC converters 204 are closed, to brake electricity Traction networks 1 can be directly fed back to.And first controller 205 two-way DC/DC converters 204 are controlled according to the voltage U of Traction networks The braking electric energy of train 2 is absorbed by battery 202.
Also, in one embodiment of the invention, the braking recovery system of train further includes：Energy-accumulating power station 3, wherein Energy-accumulating power station 3 is connected with Traction networks 1, and energy-accumulating power station 3 includes second controller 301, and second controller 301 is used for according to Traction networks Voltage U or control centre 4 issue instruction control energy-accumulating power station 3 carry out charge or discharge.Wherein, energy-accumulating power station 3 may include At least one energy-storage battery and corresponding two-way DC/DC converters.In an embodiment of the present invention, as shown in Fig. 2, energy-accumulating power station 3 may include multiple 160KW-80KWh modules, and the anode of multiple 160KW-80KWh modules is connected, and passes through positive cabinet and Traction networks 1 anode is connected, and the cathode of multiple 160KW-80KWh modules is connected, and is connected with the cathode of Traction networks 1 by cathode cabinet.
Specifically, when train 2 is braked, traction electric machine is changed into generator operating mode, electricity system from motor working condition Dynamic device 201 generates braking electric energy and braking electric energy is fed back to Traction networks 1.When the train negligible amounts on Traction networks 1 are drawn Load on net 1 is smaller or Traction networks 1 on the train braked it is more when, the braking electric energy fed back on Traction networks 1 can be more than The electric energy needed for train operation on Traction networks 1, so as to cause the raising of the voltage U of Traction networks.At this point, the first controller 205 The voltage U of monitoring Traction networks 1 in real time preferentially controls train 2 when the voltage U of Traction networks 1 is increased by the first controller 205 Battery 202 absorb braking electric energy.Meanwhile the second controller 301 of energy-accumulating power station 3 monitors the voltage U of Traction networks, if arranging The voltage U of Traction networks 1 continues to increase after the battery of vehicle 2 is absorbed, then second controller 301 controls energy-accumulating power station 3 from leading Draw the absorption electric energy of net 1 to charge.Similarly, when the train quantity on Traction networks 1 is more, i.e., the load on Traction networks 1 is larger When, the voltage U of Traction networks 1 can be reduced, and the second controller 301 of energy-accumulating power station 3 monitors the voltage U of Traction networks 1 in real time at this time, when When the voltage U of Traction networks 1 is reduced, energy-accumulating power station 3 is preferentially controlled by second controller 301 and is discharged to improve Traction networks 1 Voltage.If the voltage U of Traction networks 1 continues to reduce, the first controller 205 also can control battery 202 to discharge to carry The voltage of high Traction networks 1.
It should be noted that the battery 202 of train 2 can be powered for the illumination of train, air-conditioning, multimedia.Energy storage Power station 3 may be provided among station, and the braking electric energy of recycling is used to supply for the illumination at station, air-conditioning, multimedia etc. Electricity.In this way, braking electric energy can be for recycling and reuse by battery 202 and energy-accumulating power station 3, while power transformation can be reduced The load stood, has saved the energy.

As described above, as shown in figure 11, by taking the voltage class of Traction networks is 750VDC as an example, the braking of the embodiment of the present invention The strategy of the recycling and reuse of electric energy is specific as follows：
One) recycling of electric energy is braked
According to one embodiment of present invention, in train braking, according to the voltage of Traction networks, the electricity of on-vehicle battery 202 Amount and Traction networks 1 on train 2 quantity come integrate carry out braking electric energy distribution, braking electric energy feed back to Traction networks 1 it Afterwards, consumption absorption first is carried out by other vehicles on train, superfluous braking electric energy preferentially controls battery by the first controller 205 202 are absorbed, and when on-vehicle battery 202 can not absorb or absorbability is limited, energy-accumulating power station is controlled by second controller 301 3 are absorbed.
Specifically, as shown in figure 11, when being braked to train 2, braking electric energy feeds back to Traction networks, first determines whether battery Whether 202 electricity Q is less than or equal to the first power threshold Q1, if electricity Q is less than or equal to the first power threshold Q1, battery 202 can absorb braking electric energy, at this point, the first controller 205 monitors the voltage U of Traction networks in real time, if the row on Traction networks 1 Load on vehicle negligible amounts, that is, Traction networks 1 is smaller or Traction networks 1 on the train braked it is more, the electricity of Traction networks can be caused The raising of pressure, when the voltage U of Traction networks 1 is more than the first predetermined threshold value U1, such as when 845V, the battery 202 of control train 2 absorbs Brake electric energy；If the voltage U of Traction networks 1 continues to increase after the battery of train 2 is absorbed, as the voltage U of Traction networks More than the 4th predetermined threshold value U4, such as when 855V, second controller 301 controls energy-accumulating power station 3 and absorbs braking electric energy.In the present invention Embodiment in, after control battery 202 and energy-accumulating power station 3 absorb braking electric energy, the voltage U of Traction networks 1 can be reduced, when leading The voltage U for drawing net 1 is less than or equal to the second predetermined threshold value U2, such as when 830V, controls battery 202 and energy-accumulating power station 3 stops absorbing Braking energy.
That is, as shown in figure 11, when the voltage U of Traction networks reaches the 4th predetermined threshold value U4, controlling energy-accumulating power station 3 Start to absorb braking electric energy；When the voltage U of Traction networks, which is more than the first predetermined threshold value U1, is less than the 4th predetermined threshold value U4, control electricity Pond 202 absorbs braking electric energy；When the voltage U of Traction networks is less than the second predetermined threshold value U2, braking electric energy only feeds back to Traction networks 1。
Two) recycling of electric energy is braked
When the train run in the starting of train 2 or Traction networks 1 is more, the voltage U of Traction networks 1 can be reduced, and at this time will The braking electric energy that battery 202 and energy-accumulating power station 3 recycle is discharged into the electric energy loss that Traction networks 1 can be supplemented on Traction networks 1.Specifically Ground, first determines whether the electricity Q of battery 202 is more than or equal to the second power threshold Q2, if electricity Q is more than or equal to the second electricity Threshold value Q2, then battery 202 can discharge, at this point, the voltage U of the real-time monitoring Traction networks of second controller 301, works as Traction networks Voltage U be less than the 5th predetermined threshold value U5, such as when 810V, control energy-accumulating power station 3 discharges.Further, the first control Device 205 monitors the voltage U of Traction networks, and judges whether the voltage U of Traction networks is less than the 7th predetermined threshold value U7, if the first control Device 205 judges whether the voltage U of Traction networks is less than the 7th predetermined threshold value U7, then second controller 301 controls energy-accumulating power station 3 and carries out Electric discharge, meanwhile, the first controller 205 control two-way DC/DC converters 204 enter discharge mode so that train 2 battery 202 to Traction networks 1 discharge.
In addition to this, when power supply trouble occurs for Traction networks 1, battery 202 can be controlled and enter discharge mode, to realize row The emergency driving of vehicle 2.
In this way, the braking power consumption that absorbed in battery 202 and energy-accumulating power station 301 can be fallen, in order to 202 He of battery Energy-accumulating power station 301 continues the recycling of braking energy, saves operation cost.
