Technical Field
The invention relates to the technical field of intelligent substations, in particular to a telemechanical warning information acceptance system and method for an intelligent substation.
Background
And before the newly-built transformer substation is put into operation, the in-station alarm information needs to be checked and accepted.
At present, the work of checking and accepting the warning information of a newly-built substation generally comprises two stages: in the first stage, a communication channel between the transformer substation and the master station is not communicated, and a worker actually operates equipment in the transformer substation to check and accept background alarm information; and in the second stage, after the communication channel between the transformer substation and the master station is opened, in-station debugging personnel and master station monitoring personnel communicate through a telephone, in-station debugging personnel actually operate relevant equipment on site in the transformer substation point by point, alarm information is transmitted to the master station through telecontrol, and the master station monitoring personnel confirm the correctness of the alarm information.
The above acceptance mode has the following inherent defects:
1) part of the work needs to be repeatedly completed
Before and after the communication channel between the transformer substation and the master station is communicated, workers in the transformer substation need to actually operate all equipment twice before and after; namely: in the first stage, workers in the transformer substation need to check and accept background alarm information by actually operating equipment in the transformer substation; in the second stage, monitoring personnel of the main station check the telecontrol alarm window, and workers in the transformer substation perform actual equipment operation.
2) The monitoring personnel of the main station must participate in acceptance
In the second stage of acceptance, the monitoring personnel of the main station not only need to keep telephone contact with the debugging personnel of the transformer substation constantly, but also need to pay attention to the alarm information window of the main station in real time and make timely judgment, so that the labor intensity is high, and for the monitoring personnel of the main station, the monitoring personnel of the main station basically have no time to deal with relevant matters of other transformer substations.
3) The acceptance time is restricted by the communication channel
The telemechanical warning information can not be debugged and checked in advance before the communication channel between the transformer substation and the main station is not linked under the limitation of communication channel service opening between the transformer substation and the main station.
