[Abstract]:With the development of national economy, the State Grid Company has put forward the development plan of "strong Smart Grid". Digitization and intelligentization become the key to its development and face the new development requirements. Smart substation has become the only way for the future development of power grid, and the research of information recording and network communication technology of intelligent substation has become the most important research. In this paper, the communication message of intelligent substation is deeply studied. Through the analysis of network communication, the information record and analysis of intelligent substation are studied, and the following aspects are emphasized: 1) according to the characteristics of the information structure in the intelligent substation, the relevant information in the intelligent substation is separated by passive light separation technology, without affecting the secondary equipment to obtain the information. The signal with a certain proportion of energy is extracted from the original optical signal for monitoring, which avoids the inconsistency between the acquisition of the monitoring signal by the switch and the transmission of the original signal from point to point. (2) aiming at the problem of synchronous detection of merging units, this paper proposes to use communication monitoring technology to access different merging units at the same time. At the same time, the sampling value information issued by all the connected merging units is recorded and monitored.; the waveform of each sampling value message is analyzed; and the time error recorded between each merging unit and the sampling value information at one point is analyzed. In order to achieve the synchronization of the combined units test. Aiming at the problem of the conformance detection of the waveform of the combined unit, this paper puts forward the technique of passive light splitting and signal transmission and monitoring. At the same time, the input signal and output signal are monitored, and the corresponding sample waveform is drawn for comparison and analysis. On the one hand, we check the consistency of waveform at both ends, on the other hand, we calculate the transition delay of merging unit, and then evaluate the usability of merging unit. 4) aiming at the problem of analyzing the information of communication record, the paper puts forward to convert the information of communication record into fault record file, that is, COMTRADE file. The converted fault recording file is provided to the professional analysis tool for detailed analysis.
