Problems solved by technology

[0003] At present, in the early power system, the standby automatic switching device is only realized in the station end, and it is impossible to realize the circuit breaker control in two or more different station ends remotely. For the station end connected to the power plant, there is a large power grid risk and lead to power plant "islanding" effect

Embodiment Construction

[0035] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0036] Such as figure 1 The shown remote backup automatic switching system for power plants includes: a server, a plurality of backup automatic switching control terminals and station-side circuit breakers, and the server is connected to the backup automatic switching control terminal through a network. Among them, the power plant is connected to a plurality of power grid sites through access lines, and the standby self-injection control terminal is respectively set on each access line. The station end circuit breaker is installed in each power station end, and is used to control the switch of the power station end. The station end circuit breaker is connected with the controller signal of the standby self-injection control end on the same access line.

[0037] The standby self-switching control terminal is used to monitor the electrical parameters of ...

Abstract

The remote spare power automatic switching system for the power plant comprises a server and a plurality of spare power automatic switching control ends, and the server is in network connection with the spare power automatic switching control ends; the power plant is connected with a plurality of power plant terminals through access lines, and the spare power automatic switching control terminals are respectively arranged on the access lines; the spare power automatic switching control end is used for monitoring electrical appliance parameters of an access line, sending the electrical appliance parameters to the server end, and controlling the access line to be switched off or switched on according to a control command of the server end; and the server side is used for receiving the electrical parameters sent by the spare power automatic switching control ends, judging the operation state of the access line according to the electrical parameters, and sending control signals to the corresponding spare power automatic switching control ends according to the operation state. According to the invention, remote spare power automatic switching of multiple access ends of the power plant can be realized, and the island effect of the power plant is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electric power control, and more specifically relates to a remote backup and automatic switching system for power plants. Background technique [0002] The backup power automatic input device (referred to as standby self-injection) is a device that can automatically put the backup power into work quickly when the power system fails or other reasons cause the working power to be disconnected, or automatically put the equipment that has been powered off into other normal working power sources. , an automatic device that enables the user to quickly restore power. [0003] At present, in the early power system, the standby automatic switching device is only realized in the station end, and it is impossible to realize the circuit breaker control in two or more different station ends remotely. For the station end connected to the power plant, there is a large power grid risk and lead to the "islanding" effect ...
