Monitoring method for smart grid remote control command transmission whole process information

Abstract

The invention relates to a monitoring method for smart grid remote control command transmission whole process information, which belongs to the technical field of transmission of digital information.The method comprises steps: a protocol information matching rule table for a transmission process of a remote control command among communication layers of the grid is established; a corresponding first transmission process queue table, a second transmission process queue table and a transmission whole process queue table are established according to the matching rule table; after packets for three protocols monitored in real time are compared with the matching rule table, the protocol information of a packet which meets the matching rule table is extracted to generate remote control step information and the information is stored in the first and the second transmission process queue table; after the remote control step information is aggregated and is compared again with the matching ruletable, and the remote control step information matched with the rule table is stored in the transmission whole process queue table; and finally, all remote control step information forms remote control command transmission whole process information to be stored and displayed, and thus, monitoring on the whole process of transmission starting from a dispatching master station to each communicationlayer is completed.

Description

technical field [0001] The invention relates to a monitoring method for the whole process of information transmission by a remote command of a smart grid, and belongs to the technical field of digital information transmission. Background technique [0002] With the continuous advancement of smart grid construction, the construction of intelligent substations and smart grid control technical support systems have been completed one after another, providing important technical support for the integrated construction of regional dispatch and control of the "big operation" of regional power grids. In the power system, the dispatching master station executes a remote control command for components such as knife gates or switches, which is sent to the dispatching network through the control front, and multiple gateway machines (multiple regional dispatching substations) linked to the dispatching network receive the command from the dispatching network. After receiving the remote co...

[0003] Massive 104, MMS, GOOSE and other data or messages are received and sent all the time between the above communication layers, especially in the case of multiple gateways connected to the dispatching network, the message data is even larger, The same remote control command is scattered and out of order among the messages of different communication layers, and it is impossible to clearly express which remote control step belongs to which remote control process; because the semantics in the messages of each layer are different, the current method is Extracting the messages of each layer and analyzing them separately is not only a heavy workload, but also cannot obtain the interactive data of power grid regulation in a timely and comprehensive manner; in addition, once the remote control command is abnormal, it cannot be traced back
