According to one embodiment of present invention, after battery 202 absorbs braking electric energy, when the voltage U of Traction networks is more than When third predetermined threshold value U3,205 control machinery brake 207 of the first controller, which starts cooperation electric brake 201, carries out train 2 Braking, wherein third predetermined threshold value U3 is more than the first predetermined threshold value U1.In an embodiment of the present invention, if on Traction networks 1 Train is less, or the train braked at this time is more, then after battery 202 and energy-accumulating power station 3 absorb braking electric energy, Traction networks 1 voltage U will continue to increase, and when the voltage of Traction networks 1 is more than third predetermined threshold value U3, control machinery brake 207 starts, To carry out auxiliary braking to train 2.
Specifically, after battery 202 and energy-accumulating power station 3 absorb braking electric energy, the voltage U of Traction networks will continue to increase Adding, the first controller 205 monitors the voltage U of Traction networks in real time, if the voltage U of Traction networks is more than third predetermined threshold value U3, First controller, 205 control machinery brake 207 starts, in this way, passing through mechanical braking while carrying out electric braking to train 2 Auxiliary braking is carried out to train 2, is more than maximum to avoid the voltage U of Traction networks to reduce the braking electric energy of the generation of train 2 Constant voltage, and precisely quickly parking may be implemented.
It should be noted that when the travel speed of train 2 is less than 5Km/h or needs inlet parking, can equally control Mechanical brake 207 processed is opened to be braked to train 2.
As described above, by taking the voltage class of Traction networks is 750VDC as an example, the embodiment of the present invention carries out returning for braking electric energy The strategy received and recycled 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 U of Traction networks 1, on-vehicle battery 202 The quantity of train 2 on electricity Q and Traction networks 1 carries out the distribution of braking electric energy to integrate.Specifically, it is fed back in braking electric energy After Traction networks 1, consumption absorption first is carried out by other vehicles on train, superfluous braking electric energy is preferentially by the first controller The on-vehicle battery 202 of 205 control braking trains itself is absorbed, and can not be absorbed in on-vehicle battery 202 or absorbability is limited When, energy-accumulating power station 3 is controlled by second controller 301 and is absorbed, later, if the voltage of Traction networks 1 continues to increase, in control The battery that the heart 4 then controls the non-brake train on Traction networks 1 is absorbed.
Specifically, when train 2 is braked, braking electric energy feeds back to Traction networks, first determines whether the electricity Q of battery 202 Whether the first power threshold Q1 is less than or equal to, if electricity Q is less than or equal to the first power threshold Q1, battery 202 can absorb Electric energy is braked, at this point, the first controller 205 monitors the voltage U of Traction networks in real time, if the train negligible amounts on Traction networks 1 Load i.e. on Traction networks 1 is smaller or Traction networks 1 on the train braked it is more, the raising of the voltage of Traction networks can be caused, when The voltage U of Traction networks 1 is more than the first predetermined threshold value U1, such as when 845V, and the battery of control braking train itself absorbs braking electricity Energy；If the voltage U of Traction networks 1 continues to increase after the battery of braking train itself is absorbed, as the voltage U of Traction networks More than the second predetermined threshold value U2, such as when 855V, second controller 301 controls energy-accumulating power station 3 and absorbs braking electric energy.In control electricity After pond 202 and energy-accumulating power station 3 absorb braking electric energy, if the voltage U of Traction networks 1 continues to increase, when the voltage of Traction networks 1 is big When third predetermined threshold value, control centre 4 controls the battery in non-brake train and absorbs braking electric energy.In the embodiment of the present invention In, after the battery of control braking train absorbs braking electric energy, the voltage U of Traction networks 1 can be reduced, as the voltage U of Traction networks 1 Less than or equal to the 4th predetermined threshold value U4, such as when 830V, the battery for controlling braking train stops absorbing braking energy.
