Abstract

The present invention discloses an ac-dc-ac station electric power source which is suitable for the electrified railroad and comprises an input unit, a first power converting unit, a second power converting unit, a third power converting unit, a fourth PIC controller, a display interface and an user manually input unit. The invention has the following advantages: facilitating the good versatilityand easy maintenance by the designing of module, being able to use the lower-power grade device by the main circuit of single module, reducing the system cost, and excellent heat radiating property; increasing the stability of the system; facilitating the complete system function by the idea of multiple-core designing, excellent property and parallel processing of each core to double the processing speed of the system; obtaining full utilization of chip resource of each control core, adopting the cheap digital processing chip and low integrated cost.

Description

1. Technical Field [0001] The invention relates to an AC, DC, and AC power supply, in particular to an AC, DC, and AC station power supply for electrified railways. 2. Background technology [0002] In the technical transformation of power supply for stations in semi-blocked sections of electrified railways, as well as in the power supply systems of stations in fully blocked sections of electrified railways, in order to ensure the uninterrupted and reliable power supply of loads such as station signals and communication systems, it is necessary to directly obtain power from the traction network. A power supply device that can also take electricity from the battery pack. The power supply device should have high reliability, large electrical capacity and long-term network disconnection power supply capability, while providing technical support for railway speed increase, while saving electricity costs. In areas with underdeveloped power supply in remote mountainous areas, it can a...
