Intelligent substation self-adaptive Standby power supply automatic throw-in equipment and method

Abstract

The invention provides intelligent self-adaptive automatic throw-in equipment and a method thereof of emergency power supplies in a substation. The device comprises a first fiber-optic communication module, a second fiber-optic communication module and a controller, wherein the controller is connected with a process layer network by the first fiber-optic communication module and used for exchanging SV and GOOSEs (generic object oriented substation events) messages as well as exchanges MMS information with a station control layer network. According to the invention, the running conditions of abreaker in a primary system can be identified automatically; and by combining corresponding voltage current magnitudes for identification, a substation island can be generated in accordance with network topology analysis. The device can adapt to the change conditions of the primary system, and finishes to switch power supplies in the substation in accordance with a general throw-in rule of the emergency power supplies; and the device can solve the problem that emergency self-throw-in equipment replaces logics and devices resulting from the changes of the primary system in the substation, thereby providing conditions for ensuring the safety and stability of power systems.

Description

technical field [0001] The present invention relates to a device and a method in the technical field of electric power systems, in particular to a device and method for automatically switching on an adaptive backup power supply of an intelligent substation based on real-time topology analysis. Background technique [0002] In order to ensure the reliability of the grid power supply and ensure the uninterrupted power supply of the more important loads, two independent power supplies are usually used to supply power to one load. In the event of a power outage and voltage loss, the backup power supply is automatically switched on to continue supplying power. Due to the limitations of both data acquisition and export control means, including the size of the chassis, the number of traditional analog collectors, the number of export relays, the length of the cable line from the primary to the secondary device, and the lack of interoperability between devices, etc. , The secondary...
