Abstract
The invention discloses a network system control-based medium-voltage redundant power supply scheme for a subway train. A three-phase medium-voltage power supply bus is adopted; all three-phase AC loads on the subway train are connected to the power supply bus; the power supply bus is simultaneously powered by four low-power auxiliary converters; a train network system uniformly controls each auxiliary converter to be merged into the medium-voltage bus; and each auxiliary converter is provided with an AC voltage synchronizing device. When one auxiliary converter is broken down, the train is also powered by three auxiliary converters, and normal operation of a medium-voltage load of the train is not affected, so that the power supply reliability of the train is improved. Due to reduction of one power supply bus, a cable and a connector are reduced; the routing scheme is simplified; and the weight of the train is reduced. On the other hand, two high-power auxiliary converters are changed into four low-power auxiliary converters, so that the design difficulty and the total design cost of the auxiliary converters are greatly reduced.

The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides the middle pressure redundant power supply scheme of a kind of subway train Systematical control Network Based.
Six joint marshalings are only provided with a medium-pressure electricity supply bus, and four small-power AuCTs replace two high-power AuCTs in the past, by the grid-connected power supply of networked control system of the train AuCT.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The middle pressure redundant power supply scheme of subway train of the present invention Systematical control Network Based, adopt a three-phase medium-pressure electricity supply bus, on subway train, all three-phase alternating current loads are connected on this power supply buses, adopt four small-power AuCTs to power for this power supply buses simultaneously, be incorporated to middle pressure bus by each AuCT of the unified control of train network system, and each AuCT is provided with an alternating current voltage synchronizer.
Before four small-power AuCTs of the present invention are incorporated to middle pressure bus, need to be specified wherein by TCMS system that an AuCT is as main convertor, and other current transformers are as auxiliary current transformer; Main convertor synchronously detects without the need to carrying out grid-connected phase sequence when being incorporated to middle pressure bus, needs to carry out grid-connected phase sequence and synchronously detect when auxiliary current transformer is incorporated to middle pressure bus.
TCMS system of the present invention be random specify wherein an AuCT as main convertor.
If subway train is six joint marshallings in the present invention, described four small-power AuCTs are arranged on first and third, four, six joint trains respectively, are arranged at the often AuCT saved on train and are designated as SIV1, SIV3, SIV4 and SIV6 respectively; Described TCMS system inside is provided with the cycle accumulor counter of a 24s, and this 24s is divided into 4 time slices, and each time slice is 6s, and TCMS system specifies a wherein AuCT to start, and concrete start-up time, fragment was as follows:
| Time (s) | 0-6 | 6-12 | 12-18 | 18-24 |
| Device number | SIV1 | SIV 3 | SIV 4 | SIV 6 |
。
The present invention adopts technique scheme to have following technique effect:
When the present invention has an AuCT fault, train also has three AuCTs to power, do not affect in train and press load normally to run, thus improve train power supply reliability, owing to reducing by a power supply buses, thus decrease cable and connector, simplify cabling scenario, reduce the weight of train.
Two high-power AuCTs change four small-power AuCTs on the other hand, and AuCT design difficulty and total design cost are reduced significantly.
