Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0030] Such as figure 1 As shown, the method for stabilizing power supply under the condition of train rescue and return in this embodiment, the steps include:
[0031] 1) When the train is in the rescue return working condition, connect the pre-set low-voltage power supply to the traction converter of the train, and the traction converter controls the motor of the train to turn into a generator state;
[0032] 2) When the motor is in the generator state, the traction converter provides the electric energy fed back by the motor to the auxiliary load for power supply, and adjusts the power generation state of the motor according to the energy consumed by the auxiliary load in real time, so that the electric energy fed back by the motor is equal to that required b...

The invention discloses a stable power supply method for a train under a rescue returning working condition. The stable power supply method comprises the steps that (1) when the train is in the rescue returning working condition, a pre-arranged low-voltage power source is connected into a traction converter of the train, and a motor of the train is controlled by the traction converter to be switched into a power generator state; and (2) when the motor is in the power generator state, the traction converter provides the electric energy fed back by the motor for an auxiliary load for power supply, and the power generation state of the motor is adjusted in real time according to energy consumed by the auxiliary load, so that the electric energy fed back by the motor and the energy consumed by the auxiliary load are balanced. The stable power supply method for the train under the rescue returning working condition has the advantages that operation is easy and convenient, the required cost is low, power can be supplied to the auxiliary load when the train is in the rescue returning working condition, and the stability of power supply is maintained.
Description
technical field [0001] The invention relates to the technical field of train rescue return, in particular to a method for stabilizing power supply under train rescue return working conditions. Background technique [0002] During the operation of the train, there may be a situation where the power cannot be obtained from the grid due to the failure of the pantograph. Usually, at this time, it can only be returned to the station by means of rescue by other vehicles. During the rescue and return process of the train, if the auxiliary equipment (including air conditioning, lighting and other equipment) of the rescued train can be maintained to work normally, and the normal power supply of the auxiliary equipment can be maintained, it can still provide a comfortable environment for passengers to ride in the event of a failure, and relieve the crew. The work pressure of personnel and drivers. At present, there are few studies on the train rescue return technology, especially the...
