Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The invention provides a backup self-switching device with the function of regional self-switching, which is suitable for the power supply system with a dual power supply serial supply structure. Refer to figure 1 shown. Power station 1 and power station 2 are two power stations. Station A, station B and station C are three series power supply substations. 001-008 are the switches for each series supply. Among them, 005 is the open-loop point under the current operation mode. The scale of the series power supply structure shown in this figure is only an example. When the number of series power substations and series power switches increases or decreases, the present invention is still applicable. The dual power sources in this figure are power station 1 and power source station 2 in form. For other forms of dual power sources, for e...

Abstract

The invention discloses a backup automatic switching apparatus with an area automatic switching function, used for a power supply system of a dual-source serial supply structure. The backup automatic switching apparatus comprises an area backup automatic switching device and a plurality of acquisition and execution units, the area backup automatic switching device is configured at any one power supply station or any one serial supply transformer station, the plurality of acquisition and execution units are respectively arranged at two power supply stations and each serial supply transformer station, and all the acquisition and execution units respectively interact real-time information with the area backup automatic switching device through a fiber communication network; and each acquisition and execution unit acquires analog quantity information of the station corresponding to each acquisition and execution unit, after converting the analog quantity information into switching quantity information, uploads the switching quantity information to the area backup automatic switching device, at the same time, receives switching-off and switching-on commands transmitted down by the area backup automatic switching device and executes switching-off and switching-on motion. By using the backup automatic switching apparatus provided by the invention, power supply can be quickly recovered for a power-off serial supply transformer station through switching-off and switching-on operation at a time when any one serial supply switch is taken as an open loop point. The invention also discloses a backup automatic switching method for a backup automatic switching apparatus with an area automatic switching function.

Description

technical field [0001] The invention relates to an automatic switching device for power transmission and distribution in a power system, in particular to a microcomputer standby power automatic switching device and method. Background technique [0002] In recent years, standby automatic switching devices have been widely used in power grids of 220kV and below, and have played an important role in maintaining the stability of the power grid and improving the reliability of power supply. [0003] If the standby automatic switching device is to function, there must be a backup power supply and a backup switch in a hot standby state. When the working power supply loses power, the backup self-switching device jumps off the switch of the original working power supply, closes the switch of the backup power supply, realizes the rapid and automatic input of the backup power supply, and restores the power supply for the substation. The backup switch in the hot standby state of the ba...
