Embodiment

[0022] like figure 2 As shown, a low-emission, high-environmental-friendly double diesel generator set shunting locomotive power source includes a diesel generator set, a traction converter and a locomotive power battery system, and the alternating current generated by the diesel generator set passes through the traction converter The AC / DC conversion module rectifies and filters it into direct current through the supporting capacitor, and the two poles of the supporting capacitor are connected to the power battery of the locomotive power battery system. There are two diesel generator sets, which are diesel generator set 1 with relatively small power and relatively Larger diesel generator set 2, the output of diesel generator set 1 is controlled by switch 1, the output of diesel generator set 2 is controlled by switch 2, and the locomotive microcomputer controls the excitation drive module of diesel generator set 2 according to the information provided by the driver controller...

Abstract

The invention discloses a low-emission highly environment-friendly shunting locomotive power source of double diesel generating sets. The shunting locomotive power source includes the first diesel generating set with relatively lower power, the second diesel generating set with relatively higher power, a traction converter and an engine power battery system; alternating current emitted by the twodiesel generating engines is rectified by an AC / DC conversion module in the traction converter and converted into direct current by means of filtering of a supporting capacitor; the two electrodes ofthe supporting capacitor are connected to a power battery of an engine power battery system, and an engine micro-computer controls an excitation driving module of the second diesel generating set according to information supplied by a driver controller. Through adoption of the two diesel generating sets different in power, the first diesel generating set lower in power runs for a long time at rated power, and the second diesel generating set higher in power only runs when the engine power battery system breaks down, and low-running traction work or big-load shunting traction work needs to be done, and the switch engine power source has the advantages of being low in emission and highly environmentally friendly.

Description

technical field [0001] The invention relates to a shunting locomotive power with double diesel generator sets, which adopts two diesel generator sets, has the characteristics of low emission and high environmental protection, and belongs to the technical field of rail transportation. Background technique [0002] At present, domestic and foreign oil-electric hybrid shunting locomotives are composed of a diesel generator set and a power battery, such as figure 1 shown. Regardless of whether the locomotive diesel generator set and the power battery are mildly mixed, moderately or heavily mixed, the power of the on-board diesel generator set is quite large, and it is quite difficult to achieve low emissions and high environmental protection. Contents of the invention [0003] The object of the present invention is to provide a low-emission, high-environmental protection shunting locomotive power source and a power supply method thereof with dual diesel generator sets.
