Abstract
The invention discloses a power supply system used for diesel locomotives and diesel motor cars. The power supply system includes a three-phase alternating current generating set, and the three-phase alternating current generated by the three-phase alternating current generating set falls into two circuits. In each circuit, the three-phase alternating current is rectified into stable direct current by a high voltage rectifying device and a high voltage capacitor respectively, the direct current then passes through a resistance braking converter, an auxiliary converter and a traction converter in order, and finally drives a three-phase asynchronous traction motor. The resistance braking converters are disposed between the high voltage rectifying devices and the auxiliary converters. The two resistance braking converters are connected to a resistance braking device together, the output current of the two auxiliary converters is connected to a filter together to undergo filtering treatment, and is then output through a power supply transformer. According to the power supply system provided by the invention, one generating set can supply power to each system of a locomotive in the same system, and the energy can realize mutual complementation. Also resistance braking energy can be fully utilized to improve the running economical efficiency of a whole train, thus reducing the operation cost of users.

The three plase alternating current that described three phase alternator group produces divides two-way; Each road is rectified into stable direct current through high-voltage rectifying device and high-voltage capacitor respectively, more successively by rheostatic brake current transformer, AuCT, traction convertor, finally drives phase asynchronous traction electric machine.
Between described high-voltage rectifying device and AuCT, rheostatic brake current transformer is also set; Described two rheostatic brake current transformers are connected with rheostatic brake device jointly, and the outgoing current of two AuCTs is also jointly connected to filter and carries out filtering processing, then by supply transformer, exports.AuCT converts the HVDC after high-voltage capacitor rectification to the power supply of frequency and voltage constant, and filter improves the quality of power supply.
As optimal way, high pressure three phase switch is set between described AuCT and filter.After arranging like this, can control easily disconnection or the closure on this road of filter.
As optimal way, described supply transformer output AC-HEP, AC220V, AC-aux, supply transformer is also exported respectively DC-aux, DC24V by electric power conversion apparatus.
AC-HEP three plase alternating current provides power for passenger train, AC220V alternating current provides miniwatt household electricity for locomotive, AC-aux three plase alternating current provides the power supply of frequency and voltage constant for locomotive assisting system, and DC-aux, DC24V provide power for locomotive storage batteries charging, DC machine, illumination, electric component, microprocessor control system, diesel engine control system.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: simplified locomotive system, improved locomotive reliability; In same system, can be that locomotive assisting system, power supply system of train, locomotive traction system are powered by same generator set, its energy can supplement mutually; Also can make full use of rheostatic brake energy, improve the economy of the operation of whole train, reduce user's operation cost.
