Detailed Description
Examples
In the monitoring method for transmitting the whole process information by the remote control command of the intelligent substation, the communication of the intelligent substation is sequentially divided into five communication layers of a regulation and control front layer, a scheduling net layer, a station control layer, a spacing layer and a process layer, the remote control command is transmitted by messages formed by different protocols on the five communication layers, and the specific messages include: the method comprises the steps of regulating and controlling 104 messages from a front layer to a scheduling network layer, 104 messages from the scheduling network layer to a station control layer, MMS messages from the station control layer to a spacer layer and GOOSE messages from the spacer layer to a process layer, wherein the messages are obtained in real time through a power communication protocol detector. As shown in fig. 1, the specific monitoring method includes the following steps:
1) and establishing a protocol information matching rule table for transmitting the whole process of the remote control command among five communication layers according to the corresponding relation of the remote control command among the three protocols. The matching rules table is shown in table 1 below:

Each remote control command forms corresponding protocol information of corresponding relations among five communication layers of a regulation front-end layer, a dispatching network layer, a station control layer, a spacer layer and a process layer, and is arranged in a matching rule table to form protocol information entries (namely rows and columns in the rule table, for example, an entry formed by each first row and each column in table 1 is Baixin 4R74 Kai-245677-CL 2201 CTRL/CBSynCSW-CL 2201CTRL/LLN0$ BR-001A:1/001A:1/00B1: 3), so that the protocol information matching rule table for transmitting the whole process among the five communication layers by the four remote control commands is established.
2) According to the matching rule table and the protocol information items thereof, establishing transmission whole process queue lists of the four remote control commands in five communication layers of a regulation and control preposition layer, a scheduling network layer, a station control layer, a spacing layer and a process layer, establishing first transmission process queue lists of the four remote control commands in the four communication layers of the scheduling network layer, the station control layer, the spacing layer and the process layer, and establishing second transmission process queue lists of the four remote control commands in two communication layers of the regulation and control preposition layer and the scheduling network layer; the first transfer process queue table, the second transfer process queue table, and the transfer overall process queue table are empty tables that completely correspond to the rows and columns of the matching rule table.
3) And filtering and classifying each monitored message according to three protocols, and extracting protocol information of each message after syntactic and semantic analysis. For example, for 104 messages, 104 remote control point numbers are extracted as specification information, for MMS messages, MMS references are extracted as specification information, and for GOOSE messages, GOOSE virtual terminals are extracted as specification information.
4) Comparing the protocol information of each of the first message and the second message with the protocol information items of the matching rule table, if the protocol information of the message is matched with the protocol information items, taking one-way transmission of the message (the first message or the second message) between the corresponding communication layers as a qualified remote control step, extracting the protocol information of the message (the first message or the second message) and storing the protocol information into a first transmission process queue list or a second transmission process queue list as the information of the remote control step, and otherwise, discarding the message (the first message or the second message).
For example: the power communication protocol detector monitors an MMS message from the station control layer to the spacing layer in real time, and the MMS message is judged to be a qualified remote control step from the station control layer to the spacing layer once by comparing protocol information items of the matching rule table, if the MMS message is matched, control reference ykdesc and report reference ykref protocol information in the MMS message are extracted and stored in a second transmission process queue table to serve as information of the qualified remote control step.
5) Summarizing the information generated in the step 4) in the remote control step, comparing the summarized information with the protocol information items of the matching rule table, if the protocol information contained in the information in the remote control step is matched with the protocol information items, storing the information in a transmission whole-process queue list, otherwise, discarding the information in the remote control step;
6) and sorting the information of each remote control step in the transmission overall process queue list according to time, calculating the time interval from the information of the first remote control step to the information of the last remote control step, and if the time interval exceeds the set time, extracting the information of each remote control step in the transmission overall process queue list to form a remote control command transmission overall process information, and storing and displaying the remote control command transmission overall process information.
In this embodiment, generally, the setting time range is 5 to 30 seconds; the matching rule table is a semantic association table formed by associating the semantics of different conventions.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and all the technical solutions and the concepts of the present invention are equivalent to or changed within the scope of the present invention.
