Embodiment Construction

[0018] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 In the flow chart of the above steps given in , "main channel" is used to represent the main channel of the power dispatching automation system, and "standby channel" is used to represent the standby channel of the power dispatching automation system. When monitoring the main and standby channels, respectively The protocol analysis is performed on the active and standby channels, and the time events on the active and standby channels are formed respectively, and the events on the active and standby channels are automatically compared.

[0020] figure 2 It is to use the equipment connection diagram of the present invention in the electric power dispatching automation system, and in practice the method of the present invention can pass figure 2 equipment is applied. Such as figure 2 As shown, among them, the plant sta...

Abstract

The invention discloses an intelligent comparison method for main channel information and standby channel information of a power dispatching automation system. The method is characterized by comprising the following steps: first, acquiring the main channel information and the standby channel information in the same set time period in a network mirror port monitoring mode; second, performing shift-reduce parsing on the acquired main channel information and the standby channel information in real time to form events about a main channel and a standby channel, and storing the events of the main channel and the standby channel in a database; third, automatically comparing the events of the main channel and the standby channel to generate a comparison result, if the comparison result is abnormal, triggering to generate an alarm event, storing the alarm event in the database and displaying the alarm event in real time. By the method, the availability of channel data can be improved greatly, and the abnormity of the channel data can be discovered in time, so that the hot standby state of the standby channel is really in an available state at any time, and finally, a powerful guarantee is provided for improving the safe and stable operation of the power dispatching automation system.

Description

technical field [0001] The invention relates to an information intelligent comparison method, in particular to an information intelligent comparison method for main and standby channels of an electric power dispatching automation system, and the invention belongs to the technical field of electric power system automation. Background technique [0002] In order to ensure the high reliability of the communication quality, the communication between the power dispatching automation system at all levels and each plant station generally adopts a redundant configuration mode in which dual channels or multiple channels are used as backups for each other. Under the extensive use of dual-channel redundant configuration, the main and standby channels are simultaneously online for real-time communication (that is, they are hot standby for each other), and the master station uses the data uploaded by the duty channel, and issues commands such as time synchronization and remote control thr...
