Power supply device for transformer substation

Abstract

The invention relates to a power supply device for a transformer substation, which comprises two transformers (1,2) and two ATS switches (3,4), wherein ATS switches are connected with sections of alternating current buses (5,6) respectively; each section of the alternating current bus is connected with an alternating current feeder module, a charging module, an intelligent lighting feeder module and the like; and each charging module is connected with the same alternating current bus (7), and the alternating current buses are connected with two sets of the direct current feeder modules, two sets of inversion power modules, two sets of DC-DC modules and one set of accumulators (8) respectively. The power supply device has the advantages that: all the switches are intelligently modularized and integrated in a chassis; a switch programming control hardware platform is established and modules are integrated into the network through network communication technology, so the power switch for the transformer substation has the functions of activating preset programs and completing programmed operation besides the conventional manual control, remote control and protective control according to related information triggering conditions.

Description

Technical field: [0001] The invention relates to a power supply device for a substation station. Background technique: [0002] At present, the technology of AC power supply and DC power supply equipment used in domestic substations is relatively mature, but the idea of ​​independent development of DC and AC has been used in China. The power consumption of the substation station includes AC system, DC system, UPS uninterruptible power supply system, communication power supply system, etc. These power systems have been produced and installed by different suppliers, and management has been assigned different professionals for maintenance. There are some drawbacks to this model: [0003] (1) It is difficult to achieve system management for existing substation power supplies: AC systems provided by different suppliers are generally incompatible with DC system communication protocols; AC and DC cannot be coordinated, AC and DC information sharing is poor, and it is difficult to achiev...
