Abstract

The embodiment of the invention provides an electric transmission system which comprises a control device and a traction device. The traction device comprises a first rectification module, an invertergroup and a motor group. The first rectification module is respectively connected with the control device and the inverter group. The inverter group is connected with the control device, the first rectification module and the motor group. The motor group comprises at least one motor. The control device is used for determining the transmission ratio of the motor according to configuration information of a first train, and the first train is a train which is to be equipped with the electric transmission system. The control device is also used for determining electric signal power output by theinverter group according to the transmission ratio. The control device is also used for determining control information according to the electric signal power and sending the control information to the inverter group. The inverter group is used for determining the power of an output electric signal according to the control information. The universality of the electric transmission system is improved, and the electric transmission system can be applied to different trains.

Description

technical field [0001] Embodiments of the present invention relate to the field of electric locomotives, and in particular, to an electric drive system. Background technique [0002] Rail transit trains are equipped with electric drive systems, and the electric drive systems of electric locomotives usually include traction devices, auxiliary systems and network systems. [0003] In practice, the traction device is used to drive the electric locomotive, the auxiliary system is used to eliminate the heat generated by the traction device and supply power to the loads in the electric locomotive (such as air conditioners, lighting, etc.), and the network system is used to control and monitor traction. Operation of devices and auxiliary systems, storage of control commands and detection data, and display of control and monitoring status of traction devices and auxiliary systems to locomotive drivers. [0004] In the prior art, an electric drive system is usually designed accordin...
