Transforming plant communication supervisor and device for monitoring channel status

Abstract

The invention discloses a monitoring device of a substation communication management machine and channel status and relates to the monitoring technical field; the monitoring technical problems of the communication management machine and the channel status are solved; the monitoring device comprises all the channels and is characterized in that: the monitoring device further comprises a switch of a normally closed contact for controlling the power supply of the management machine; a channel detecting module for detecting the working status of all the channels, and connecting and controlling the switches for reposition of the management machine (working procedure); and a wireless communication module which is connected with a communication detecting module for the communication of the management machine and the wireless transportation of the working status signal of the channels. The monitoring device has the characteristics of reducing the maintenance cost of the substation communication management machine and the channel status and leading faults to rapidly and accurately notify maintainers.

Description

technical field [0001] The invention relates to a monitoring communication technology, in particular to a monitoring communication technology used for substation communication management machines and channel working states. Background technique [0002] In the power system, the basic situation is that a dispatch center controls dozens of substations. The dispatch center is in the urban area, and the substation is tens of kilometers or even hundreds of kilometers away from the dispatch center. In order to realize power automation, each substation communicates with the dispatcher, and the communication methods include telephone communication, carrier modem communication, microwave communication, optical fiber communication, etc. Taking cost and effect into consideration, carrier modem communication is generally used at present, and optical fiber communication is used in a few places with good conditions. It is conceivable that communication is a very critical link. If there ...

Problems solved by technology

This method has great limitations: if the communication management machine fails, the dispatch center cannot see the status of each channel, and cannot judge whether the management machine fails or the channel from the management machine to the dispatch center fails

Similarly, if the channel from the management machine to the dispatch center fails, the dispatch center will not be able to see the status of each channel, nor can it determine whether the management machine is faulty or the channel from the management machine to the dispatch center is faulty.

In the power system, the maintenance of the general management machine belongs to the dispatching department, while the maintenance of the communication channel belongs to the communication department. Since it is impossible to determine whether the failure of the management machine or the failure of the channel from the management machine to the dispatching center, both departments can only send personnel Go to substations tens of kilometers or even hundreds of kilometers away to check and repair, resulting in a waste of manpower and material resources
