Problems solved by technology

[0003] The power dispatch automation master station system sends the received alarm information from the substation to the alarm window display or saves it in a file. However, when a new station is commissioned or an abnormal situation occurs in a substation, a large number of alarm information enters the dispatch system, and the controller Single-point, interval, or whole-site alarm suppression cannot be performed on the alarm direct transmission screen information
At this time, a large number of alarms directly transmitted to the screen will seriously interfere with the normal monitoring work

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, a method for realizing alarm information transmission of master and sub-stations based on a service subscription method includes the following steps:

[0025] Step 1, the power dispatching automation master station establishes an association with the file service of the power system general service agreement at the sub-station end;

[0026] Step 2, the power dispatch automation master station system obtains the file list of the sub-station end through the file service of the power system general service agreement provided by the sub-station end;

[0027] Step 3, the power dispatch automation master station system obtains the configuration file of the alarm information list of the sub-station through the file service of the power system general service agreement provided by the sub-station;

[0028] The first column in the file is the...

Abstract

The invention discloses a main and sub station warning information transmission implementation method based on a service subscription mode. A power dispatching automatic main station utilizes a service architecture of a universal service protocol between the main station and a sub station and implements subscription, effect taking and real-time receiving of the power dispatching automatic main station on sub station warning information by a file service and an event service which are provided by the sub station, and thus, warning occurring to the sub station is timely and accurately known and processed without being delayed due to problems of uncertainty of the warning information and the like, so that risk resistance of a system is improved.

Description

technical field [0001] The invention relates to a method for realizing alarm information transmission of master and sub-stations based on a service subscription mode, and belongs to the technical field of electric power dispatching automation. Background technique [0002] At present, the basic application of alarm direct transmission has been realized in all levels of power dispatching automation systems, that is, the substation monitoring system sends the alarm direct transmission information to the dispatching master station through the "Power System Real-time Data Communication Application Layer Protocol", and the dispatching master station After the alarm service is processed, it will be displayed by the alarm window. In the current practical application process, the dispatching systems at all levels only stay at the level of "seeing" the alarm signal, and fail to organize and effectively use the information directly transmitted by the alarm. The personnel on duty in t...
