Problems solved by technology

However, when analyzing messages in actual work, it is necessary to use a calculator to calculate the function code of the message where the point number is located, and to convert the message into binary or decimal data and then perform specific analysis. Therefore, the traditional message analysis method is cumbersome, error-prone, and time-consuming. Therefore, using the traditional message analysis method may easily lead to inaccurate analysis results when judging the cause of the fault.

Embodiment Construction

[0022] Substation automation special message analysis method of the present invention, its specific steps are as follows:

[0023] (1) Telemetry data packet analysis

[0024] (A) Calculate the function code of the required message data according to the input telemetry point number, and obtain the required message data. The specific method is as follows:

[0025] Let the input telemetry point number be a, when a is an even number, calculate the function code by the formula (a-1) / 2, and round the calculation result to an integer; when a is an odd number, calculate it by the formula a / 2 , and the method of rounding the calculation result to an integer to obtain the function code.

[0026] (B) Read the above message data, obtain the information word corresponding to the telemetry point number to be analyzed, convert the hexadecimal message data into decimal data, and output it. The specific method is as follows:

[0027] Assuming that the information words corresponding to the t...

Abstract

The invention discloses a special message analysis method for substation automation, and belongs to the technical field of corrective maintenance of electric power substations. The special message analysis method comprises the steps as follows: telemetry data message analysis: according to an input telemetry point number, calculating a function code of the required message data, obtaining the required message data, and converting the message data into decimal-system data for outputting; and remote signaling data message analysis: according to an input remote signaling point number, calculating a function code of the required message data, obtaining the required message data, and converting the message data into binary-system data for outputting. The special message analysis method has the benefits that a software program is made through the message analysis method provided by the invention to simplify cumbersome message analysis work, so that the message analysis time is reduced to one third of the original time, and the work efficiency is improved greatly; the degree of automation is high, the operation procedure is simple and convenient, and simultaneously, the accuracy of a message analysis result is improved; and a gap in the message analysis field is filled.

Description

technical field [0001] The invention relates to the technical field of fault inspection and maintenance of power substations. Background technique [0002] In the transition process of the replacement and overhaul of various DC screens in substations and in daily work, automation staff must rely on the results of message analysis as an auxiliary basis for fault analysis when analyzing faults, so as to judge the cause of the fault faster and shorten the fault time. time. However, when analyzing messages in actual work, it is necessary to use a calculator to calculate the function code of the message where the point number is located, and to convert the message into binary or decimal data and then perform specific analysis. If one step is wrong, the entire result will be damaged Therefore, the traditional message analysis method is cumbersome, error-prone, and time-consuming. Therefore, using the traditional message analysis method may easily lead to inaccurate analysis resul...
